MAI helicopter and VTOL projects

[hesham]

Hi,

A strange design to MAI, the V.Kisyelyova.

 

[Jemiba]

Looks like an ornithopter, a flapping wing design .. ???

 

[hesham]

Hi,

there was also MAI Krychit a three engined VTOL light transport aircraft.

 

[hesham]

Hi,

Anther two aircraft to MAI, the Inalyot-8 and Skat,
they also a VTOL projects.

Hesham,

Do you have any details on the tilt-wing in Post 98 and do you know if it's related in anyway to the four engined tilt-wing shown below?

I've seen this mis-identified on the Key Forums as the Kamov "Hoop", but the only other information which I've been able to find is a quote from Nigel Eastaway's Russian Aviation Research Trust which suggests that it is based on a model in MAI, which was "a student design exercise and was never a serious project considered for building. Not a total fake but probably dawn from a description of the MAI model".

Does anyone have any other information?

 

[hesham]

Sorry McGreig,

I only know that it was a really project from MAI of 1963 and not fake,
but I have no details about it,may be anyone can translate this.

Hesham,

The attached artwork comes from a Russian website, but the original source isn't a Russian one! It was published in Karl-Heinz Eyermann's "Lufttransport - Spiegelbild der Luftmacht" (Berlin/G.D.R., 1967). The illustrator tried to give an impression how we should imagine such a tiltwing design. There is no evidence for exactly this layout!

 

[hesham]

No my dear Boxkite,

In a russian site about VTOL aircraft you can find this aircraft;

Hesham, Boxkite has CLEARLY explained that the image is not authentic. Please read what he said.

Boxkite,

Thanks for the information on the source of the tiltwing art. This seems to tie into the Russian Aviation Research Trust comment in my original post that the tiltwing was "not a total fake but probably drawn from a description of the MAI model".

The history of the MAI designs (both under the Soviet regime and nowadays) is a fascinating one, full of little-known projects of all kinds.
Among these, several rotary and VTOL projects which show that the thinking on these technologies followed the same lines as what was being developed in America at the time.

These flying platforms, for instance, are reminiscent of Curtiss-Wright's, Hiller's and especially Piasecki's own projects.

1°) A VTOL platform project
2°) A VTOL platform project
3°) A VTOL platform prototype in construction (reminiscent of Piasecki's AirGeep).
4°) A VTOL platform project (looking more like an electric razor or a veggie slicer than an aircraft though!)

 

[Stargazer]

The MPVVA project of the 1980s is not unlike Hiller's Flying Platform, but it is meant as a UAV:

 

[Stargazer]

Helicopter projects also echo the work of other design bureaus in other countries:

1°) The SKB-MAI light helicopter project.
2°) A large compound helicopter project remarkably similar in concept to the British Fairey Rotodyne.

 

[Stargazer]

There was also an interest for individual, ultra-light rotorcraft.

1°) The Boldirev Gyroplan seems to follow a similar concept to the British Hafner Rotachute.
2°) Three-view arrangement of the Boldirev Gyroplan.

 

[Stargazer]

Another individual, ultra-light rotorcraft, entirely foldable, developed in the early 1970s:

1°) A. V. Gremyatskiy in his IV-4 helicopter.
2°) The Gremyatskiy IV-4 when folded.
3°) Three-view arrangement of the Gremyatskiy IV-4.

 

[Stargazer]

As for Engineer F. P. Kurochkin, he followed the path of the shoulder-mounted rotor:

 

[Stargazer]

Some other rotorcraft types were studied at MAI in the early years, some of which have already been discussed on this forum:

1°) Mikhail Sukhanov's Koltseplan STOL fighter:

2°) The Sokol, a tilt-wing VTOL fighter:
http://www.secretprojects.co.uk/forum/index.php/topic,6106.0

3°) The Bratukhin Omega-1 helicopter:

[Stargazer]

With the 1960s, the X- series of projects appears, which carry a much more distinctive appearance and present more unique concepts:

1°) The X-1 autogyro.
2°) X-1 autogyro three-view arrangement.
3°) X-3 light twin-duct flying platform three-view arrangement.
4°) The open-air X-4 three-rotor vehicle.
5°) The very similar X-5 in three-view.

 

[Stargazer]

Finally, a number of rotary wing drones or UAVs were studied (and sometimes flown). As I don't speak Russian fluently I am unfortunately unable to say what each of these was studied for!

1°) An r/c helicopter.
2°) The DPV-100 drone helicopter.
3°) The DPLA 603-03.
4°) The DPLA 603-05.
5°) The RUM-V2 co-axial r/c helicopter.
6°) The RPS-1.
7°) The RPS-2.
8°) An RPS model.

Another picture of the X-5.

Can't remember where I got it.

2°) A large compound helicopter project remarkably similar in concept to the British Fairey Rotodyne.

I believe this was Ivan Bratukhin's design study for a heavy-lift transport helicopter.

 

[Stargazer]

Faireyov Rotodynsky...

Boldirev autogyro (not Borderev):

Hi,


can we consider those MAI design,a flying platform,I mean the only lower two projects ?.

Hi,

A strange design to MAI, the V.Kisyelyova.

#Paul Atredies, your 'thopter ready at gate 8, Paul Atredies, your 'thopter is ready at gate 8". ;D

MAI Super Heavy VTOL Transport

In 1952, a special directorate devoted to helicopter design was established at the Moscow Aviation Institute (MAI), headed by academician Boris Yuriev. In 1954, a team of specialists was assembled to design a heavy VTOL vehicle, with the general configuration of a tiltrotor.

The concept was mutated and by 1956 it had changed to a Tail Sitter-type heavy VTOL transport, very advanced and ambitious for the time.
