Here are a few solutions that can some of the problems to solve..
Surely you will need to test them in practice, before se makes the right decisions as to the shape of the structure of the drive.
Perhaps such a solution with a single tube might be the most efficient, because it will most laminar flow

Or a Cutter Heron

Of course, a whole can be properly enclosed guard areodynamic...

Well, here an example, if the electric drive can also adapt to the helicopter. Turbine itself would be inside the helicopter, but it would not be permanently linked to the rotor, so that no torque moved...

It is air- gear drive

Interesting Felix.
Now check out a fully proven aircraft that has undertaken all the roles asked of it for over 40 years.
WALLIS AVIATION CONFIDENTIAL
Kenneth Wallis MBE was born at Ely Cambridge in 1916 and was educated at Kings School Ely. His interest in engineering and aviation was aroused at a very early age. His father and uncle had both raced their own motorcycles and by May 1910 had completed an aeroplane, the Wallbro Monoplane. This was very advanced for its time, with a primary structure of steel tubing and roll control by ailerons, rather than the wing warp of the day.
Upon leaving school Kenneth Wallis entered his fathers motor and cycle business.
In his spare time he built a number of high-speed boats, employing both air and under water propellers. His first racing success came at Denver Sluice Cambridgeshire in 1934 and his last was the fifty-six Missouri Marathon in the USA in 1957.
In 1937 he obtained his pilots A licence and joined the Civil Air Guard at its inauguration.
He enlisted as an RAF Volunteer at the outbreak of World War Two, serving as an operational pilot on Lysanders in 268 Squadron Army Co Operation, prior to transferring to Bomber Command in 1941, flying Wellingtons over Germany.
Exciting moments in 1941 were, a hurried parachute descent from low level at night and in fog returning from a raid, a crash landing successfully carried out after a wing had nearly been cut through by a balloon cable and a fire in the bomb load while over the target.
Upon completion of his tour of bombing operations in April 1942, Wallis commanded an aerial gunnery school at an Operational Training Unit.
In 1944 he flew a Wellington X to Italy, for further bombing operations.
Returning to the UK in 1945. He served as a Flight Commander at the Central Gunnery Training School prior to specialising in Air Armament and eventually received a Permanent Commission in the newly formed Technical Branch of the RAF.
Although in the Technical Branch, he remained in flying practise and held Green Instrument Ratings on jets.
From 1956 to 1958 he held a Technical Flying post in Strategic Air Command USA, flying the ten engine B-36 Intercontinental bombers in Europe and the Far East.
His technical posts have mostly been in the field of research and development, in the Armament Design Establishment (Small Arms), the Ammunition and Lethality Divisions of the Ordnance Board, Air Ministry and Fighter Command.
As OC Armament of the first Canberra jet bomber Station he was responsible for inventions improving the Canberra Strike Capability.
On leaving the RAF in the early 1960s, Wallis began construction of his first autogyro, although he had made extensive studies of the type over many years. Having flown almost every type of aircraft and developing armament systems at the highest level, all of which have proved successful and many of which are still in front line service, it may come as a surprise that Ken Wallis considers the autogyro to be the ideal aircraft for a tactical, front line attack and support role.
The simple construction and minimum cost of the Wallis Autogyro also make it suitable for many rolls in Civil Aviation, which are at present undertaken by much more expensive and complicated aircraft.
Since the 1960s, Wallis Aviation has undertaken a continual development program of the type and experimented with every conceivable Military and Civil application. No other constructor of autogyros has anywhere near the knowledge or practical experience of this type of aircraft. Wallis is the undisputed leader in the field.
Other autogyros at present in use, mainly for fun flying, do not have the performance of the Wallis Machines and cannot be compared.
Ken Wallis MBE now lives in Norfolk, where he continues with developments on autogyros. He has his own small airfield and experimental workshops. A hanger contains some 19 autogyros, all of which are operational and capable of fulfilling a wide range of tasks.
Wallis Type Development
The first prototype WA/116 was an open framed aircraft using a target drone engine. The type WA/116 has been continually modified and improved to successfully undertake all the operational demands placed on it and is now a fully proven aviation system with exceptional performance.
The later type WA/116 aircraft have weatherproof cockpit and all Weather capability. Various engines have been used, including the McCulloch, Rotax, Subaru and the Norton Wankel rotary.
A larger airframe was designed for the WA/117, to take a Rolls Royce 4 cylinder aero engine and this type proved equally as successful.
The WA/118/M is one in a line of high performance types using an Italian Meteor Alpha 4 cylinder supercharged radial 2-stroke engine.
WA/120/R-R is an enclosed cockpit aircraft using the R-R O-240 engine of 130hp awaiting record use.
There are a number of two seater versions, including a two seater WA/116/F-2 and the WA/122 R-R. All these aircraft have been used for demanding Military 2 seat requirements.
Wallis Autogyros Formal Testing
1961 to 63 Type WA/116
Photo recording of rotor and fuselage clearances over extreme manoeuvres and full flight spectrum.
Photo recording of control movements, fuselage response, airspeed, attitude and rotor rpm.
Electrical strain gauging of critical area of pylon tube, at that time it did not have any bracing struts, control rods, undercarriage and keel tube, over the full flight spectrum and including heavy landings, rough ground operation, etc.
Recording of altitude achieved at 100 yards from brakes off.
Climb to 7500 feet with 100 LB load.
Handling tests to fixed wing light aeroplane standards i.e. hands off recovery from unusual positions. Many landings with engine switched off from various heights.
After demonstrations to the Air Registration Board a Certificate of Airworthiness was granted in August 1962, allowing Army trials
under OR 353 to proceed.
1964 Type WA/116
Photo recording of rotor dynamics employing a high speed cine camera turning with the rotors to record blade flexing in vertical, horizontal and torsional modes.
Using wool tufts to record airflow over the blades covering a range of speeds and manoeuvres. Dynamic teeter movement checks, over the full flight spectrum, in relation to the teeter limits and the position of the rotor relative to fuselage datum was also included in all the recordings.
1970 to 74 Type WA/116 and 117
In collaboration with British Aircraft Corporation Guided Weapons Division, fuselage vibration analysis was undertaken, with a view to carriage of remote sensing equipment in an RPV version, by open shutter photography of a strobed light source on the ground at night.
With control input transducers, rate gyros in 3 axes and voice recorder, recording on an Admiralty Recorder, fuselage response to control movements and attitude. Recorded from level flight over speed range of 40 to 120 knots IAS.
Analysis was undertaken of the radar echo.
Recordings taken by kine theodolite of take offs and landings at varying all up weights.
Sound recording, measurement and analysis made, using Concorde test Laboratory.
Measurements were taken of propeller thrust over complete flight spectrum.
In collaboration with the RAE Bedford, using the BAC control response recording equipment. Further tests taken of control response of WA/117 with and without a horizontal stabiliser, control column fixed and free.
Using kine theodolites recording taken of altitude and attitude control in low level flight about 3 feet above runway accelerating 10 to 90 kts, then suddenly closing the throttle.
Flights undertaken at all up and tare weight ratio of 3.14 to 1, recording control inputs and fuselage response to throttle changes, centre of gravity changes, trim and climbs, step pulse control inputs, both with and without horizontal stabiliser.
The above tests and others were undertaken during the Vinten Licence Agreement and are recorded in the test reports, by Beagle, BAC, RAE and Wallis.
Wallis Autogyros in Working Roles
Cine
16mm and 35mm Panavision cameras rigidly mounted have been carried for cine photography for feature films such as the Eon Productions James Bond 007 film You Only Live Twice and Charles Fries Production The Martian Chronicles.
Three 16mm cameras are normally carried viewing forward and on the beam for TV Documentaries, such as Portrait of a River and the Thames Barge Race in Under Sale for the BBC.
Still Photography
Fixed aerial reconnaissance cameras in vertical and oblique modes, together with intervalometers for vertical line overlaps in formats from 70mm to 9 inch. Photography in shallow beam oblique mode, using a large format F-52 camera, with 36inch lens, has been undertaken at ranges of up to 10 kilometres, for special purposes.
F-24 cameras have been modified to produce continuous recording, to simulate infrared linescan imagery.
Hand held cameras of all sorts are also used.
Panoramic Photography
In 1978, in a flight over central London the new Vinten Type 751 Panoramic Aerial Reconnaissance camera was used for dramatic shots of the city for the SBAC show program. The camera is used in cross track and beam oblique modes.
Multi Band Photography
Multi band photographic techniques have been explored and operational roles undertaken. The system employs four F-95 70mm aerial reconnaissance cameras, with narrow cut filters, operating simultaneously. A radar altimeter is employed, for precise height control at low altitude over undulating terrain.
The System has been used for coastal ecology research, detection of buried cadavers, in experiments and operations for the Police Scientific Development Establishment.
It has also been used for the detection of crop disease and the detection of coastal pollution using the Type WA/120, fitted with a multi band camera pack.
The WA/120 was in the Science Museum Exploration Exhibition from 1976 to 1985.
Stereo Photography
Stereo Photography, using F-95 and F-24 cameras, has been undertaken for the Institute of Terrestrial Ecology and other agencies.
Tracking of Suspect Vehicles
Fitted with a special antenna array, which can be lowered beneath the aircraft in flight and a cockpit VDU, trials have been undertaken on behalf of the Police Scientific Development Establishment.
Video Recording
Video recording has been undertaken from 1970 to date.
Low light recording is undertaken in very low light conditions and at night, with a light source on the aircraft.
Video is employed as a crosscheck of visual searches, for the Police and other agencies. The use of the latest digital video systems, including Fovean sensors is being explored.
Steady Scope Visual Aid
British Aerospace Steady Scope binoculars can be used, the natural hands off stability of the aircraft allowing efficient use of the equipment.
Infra Red Linescan
First flown by day and night in 1970 on military trials, the various developments of IRLS have been carried out very successfully.
Following trials at RAE Farnborough in 1987. Miniature infrared Line Scan with real time transmission of imagery to a ground station has been employed on post strike airfield damage reconnaissance under MOD Contract.
This is the system used by the Tornado GR1 and the Euro Fighter.
Other uses are detection of leaks in water pipelines up to eight feet below the surface, detection of animals and vehicles, heat losses in buildings, hot water plumes from industrial discharges, etc.
Crop-Spraying
Using ultra low volume spray gear, which can be lowered beneath the aircraft in flight, electro statically charged droplets have been successfully discharged in experiments for the Rotherhamstead Experimental Station Ministry of Agriculture.
Other work has been undertaken for ICI, using their Electrodyn system carrying a trailing conducting lead to measure the potential difference between the earth’s surface and the discharge nozzles.
Stereo Radar
Trials have been undertaken employing a stereo radar system capable of deep penetration of land or water, for the detection of land mines or other objects.
Military and Naval Trials and Exercises
The type WA/116 aircraft built under licence by Beagle Aircraft ltd, under Operational Requirement No 353, were on trial by the Army Air Corps in 1962 to 64. The requirement was hardly realistic, calling, among other things for the installation of a very old technology A-41 radio normally used in a tank. Coupled with the noise of the then very unreliable converted McCulloch target plane engine, the weight of the radio and the discomfort of the open frame aircraft in the very cold 1962 to 63 winter, it is not surprising that the trials next involved a two-seat cabin helicopter.
The AAC finally settled for the three seat Augusta Bell 47, the Sioux.
The military XR/942 was flown by its designer in the 1962 SBAC show at Farnborough and is still in operation.
XR/943, fitted with a cockpit nacelle, as are XR/942 and 944, is well known as James Bonds Little Nellie used in the James Bond film, You Only Live Twice, shot in Japan and Spain in 1966. She has now undertaken over 700 major air displays.
Exercise Green Lanyard
In 1981 Wallis was asked to provide an aircraft for the February 1982 Aerial Quick Deployment Exercise Green Lanyard. The aircraft was transported with 42 armed troops and two road vehicles in a C/130 Hercules aircraft.
The 1962 ex military trials aircraft XR/944 was up dated by exchange of the McCulloch engine by a Certified Franklin aero engine, returned to military camouflage and in later form was fitted with two Oerlikon 81mm Sura D anti tank rockets. A fully successful anti tank role was confirmed.
Flown into the Battle Training Area in the Hercules, as soon as the aircraft was run down the ramp, it was ready for flight.
Various reconnaissance flights were undertaken operating from unprepared sites. The aircraft had the ability to taxy up to various Critical Points, which would have been inaccessible to any other aircraft.
Army Air Trials of Micro light Aircraft, Netheravon May 1983
Three Wallis aircraft, including the Rolls Royce engined WA/122, were demonstrated. Many officers, including General Sir Richard Vickers were given flight experience on the W/122. A Franklin engined WA/116 gave solo experience to AAC instructors.
Exercise Gryphons Gold
Gryphons Gold was a behind the lines exercise conducted in the STANTA training area in November 1983.
The type WA/122 and the single seat WA/116, XR/944 and a Vinten built 116 were all employed. Again the WA/122 was used to provide transport to senior officers and to provide specialists with an aerial view of progress, such as bridge building.
The ground capability of the WA/122 was appreciated by the Brigadier passenger, after landing in unprepared sites, it was possible to traverse very rough paths, under trees, to the various KPs.
Hand held video recording was undertaken with XR/944.
Demonstration and Trials at Altenstadt, Air and Land (BWB) Transport School Bavaria December 1983
Two Wallis WA/116 aircraft Franklin powered and the two seater WA/122, took part in demonstrations and provided air experience for German Military personnel, operating from the perimeter of the snow covered grass airfield.
Several officers later had solo experience, flying a WA/116 from the airfield perimeter cleared of snow at Kaufbeuren.
TLRRPS Symposium, 14 NATO Nations, Konstanz Training Area West Germany June 1984
Two Wallis WA/116s and the WA/122 two seater, were demonstrated, taking off and landing in unprepared sites.
These trials and previous demonstrations at Altenstadt, Kaufbeuren and other sites including the Wallis airfield, resulted in a military order being placed with Wallis licensees.
A German helicopter instructor was converted to PPL(G) Standards on the WA/116, in the UK, with a view to instructing on the V/122.
Roles later undertaken in Germany and in the Middle East remain confidential.
Exercise Keswick
Following Paper Study by Wallis autogyros and MOD/R&D Contracts, Wallis was contracted to prepare aircraft to take part in the Post Strike Airfield Damage Reconnaissance Exercise Keswick, at R.A.F North Luffenham in April 1987.
The WA/117 was fitted with miniature infra Red linescan and real time imagery transmission, together with an F-95 camera and controls, 720 channel radio and equipped for night flying. This aircraft was tested at RAE Farnborough prior to the exercise.
Also prepared were a Limbach powered WA/116, equipped for video recording and another WA/116 which had served as a flying test bed for several engines, including the Norton Wankel and Rotax 532.
Operations were conducted under all weather conditions by day and night. Take offs and landings at night were from a short piece of perimeter track marked by four small battery powered lanterns.
The aircraft performed exactly to the trials schedule under realistic conditions.
Naval Trials Operating from Small Fast Patrol Craft
Vosper Thornycroft (UK) ltd had expressed an interest in the possibility of the Wallis aircraft being operated from their small fast patrol vessels, which were far to small to carry a helicopter.
Take off and landing would necessitate the vessel proceeding fast enough to provide airspeed for VTOL performance from a very small platform.
Roles envisaged were over ships horizon surveillance, target identification and guidance of ships weapons to the target.
Trials started with the autogyro keeping station with a fast patrol craft on trials in the Channel. This was followed on the 9th of March 1982 by some 25 take offs and landings on the rear half deck of a flatbed lorry, at 30 and 35 mph on the runway at RAF Watton.
On the 9th of June 1982, the two seat WA/116-T was landed solo, on the cabin roof of a small pleasure vessel adapted for the trial, moving into the wind at 8 knots.
On the 10th of November 1982, the WA/116-T was out of sight of land, over a heavy North Sea swell, before finding and landing on HMS Dumbarton Castle, a fishery protection frigate having unserviceable stabilisers. The very high superstructure immediately forward of the helicopter platform caused airflow reversal but the autogyro was flown off for its return to Lowestoft.
Tests a year later were conducted with a Franklin powered WA/116, from a Vosper Thorneycroft fast patrol vessel. The clear airflow and airspeed that the vessel could provide made VTOL operation easy. Naval operation was fully proven.
SPECIAL PHOTOGRAPHY, SAUDI PORTS AUTHORITY
In October 1983 the WA/117, equipped with the Vinten Type 751 Panoramic camera and hand held aerial cameras, was transported to Saudi Arabia by an Air Saudi transport plane.
Special photography of the ports at Jeddah and Damman was undertaken, the aircraft operating from the port area, in temperatures up to 40dg Centigrade.
Very many thousands of good photographs were obtained, the aircraft often operating very close to harbour crane jibs etc, to obtain special views, in addition to conventional low and medium altitude photography.

Feliks,
I think you might get some argument from Sikorsky. Their X2 prototype achieved 260kts.
And yes, the X2 is a helicopter in the same sense that the Lynx is a helicopter. It derives all of its lift from a powered rotor. It can take off vertically, hover, and land vertically.

Getting rid of the 'troublesome' back propeller (tail rotor). is only a small part of the problem when trying to improve the efficiency of rotorcraft.
With a tip jet helicopter or autogyro convertiplane, there still needs to be a thrust method for lateral (rudder) control.
On the twin turboprop autogyro the rotodyne, the left and right airscrews were used with a wide blade pitch range to achieve lateral control.
The engines also drove two clutched compressors feeding air to the tip jets when lit, one compressor for each opposite pair of its four rotor blades.
This gave a one engined redundency with fully maintained control in tip jet flight and with the very gradual sink rate in its mainly autorotational (autogyro) flight mode, the aircraft was safer than even a fixed wing aircraft. Unlike any current helicopter.
It was often demonstrated in the hover on one engine.
On the W116 we would use two air jet bleeds from the main engine exiting at the base of the rudder, for lateral (rudder control) in hover.
There is already full cyclic control with a joy stick and tip jet throttle up will increase blade angle to match power increases for collective control.
Dont forget the W116 is a FULLY proven aviation system and these additions would produce a hugely cost effective military and civil aircraft.
With the cost being so low it could easily be built in large enough numbers to consolidate military theaters such as Irag and Afghanistan.
Unfortunately in the UK we are still dealing with corrupt military spending based on profit for other countries and back handers.

The sophisticated method of cheating is to loosen the meter from its wall mount and tilt i 90° forward. If this type of metering device is put flat on its face it stops counting..
Again, as above, it probably pays of to know when the meter man drops by for a visit.

The next higher step of the criminal history of the story is a position in front of such a device measuring large neodymium magnet.

I was with my friends in the Museum of aviation again. "I'd like him to show this demo in which the effect of the vacuum State at the top of the wings, which blows the wind from the fan, the ball is sucked in by a transparent tube
provided in the middle of the wings and a peg that pops up on the wing.
Doing this experience again, so your friend can see it, I am surprised that the ball a is NOT sucked in tube!!
It is that this experience has been vandalized, and the ball is sucked on
Vandalized based on this, with a transparent tube to the bottom was several times the seeds.
But this was not the reason for the lack of vacuum in the tube.
After arrives home, thoroughly by looking at the about the well running the show.
http://www.youtube.com/watch?v=Fb8IFfnbjY8...player_embeddedI noticed that the tube on the film extends over the upper surface of the wings have 70 mm
The vandalizet show the tube was brought down to equality with the upper surface of the wing.
And this was the main reason for the lack of vacuum in the tube !
Simply air her upper surface of the wing, when it encounters a simple hole in the wing, just get it and seeking to keep the pipes, eliminates any vacuum in it.!!
That is, that the ball could be the suck by the vacuum arising at the top of the wings, in this case the pipe must extend over the upper surface of the wing by about 70 mm !!!
When this tube does not extend, this does not transmit its down this vacuum, even in the smallest degree.
Why is this, explain the following drawings:



Yes so we are one of the one cases where due to vandalism, we fully the specificities of of the Red Baron Windmill...
According to estimates, the surface of the wing of a 100 m square, with a wind speed of 30 km\/h can produce approximately 750 KG lift.
To get 100 KG of thrust of the propeller to the ultralight trike, the engine must have a power of about 50 KW
You can take also denied that the 100 KG over da US 50 KW electrical Dynamo.
Which had managed to seize the entire lift such 100 m ^ 2 wings which is 750 KG, a power Dynamo would be 300 KW.
The Windmill of the Red Baron 100 m x 30 m = 3000 m ^ 2 and this will give us the 9000 KW.
Now you can build 10 such wings one above with which 30000 m ^ 2 = 90 MW.
No and now depends on how many% of this theoretical power we capture this lift and exchange it into electrical current.
