Its Russian the "Photon" https://www.rulit.me/books/mir-aviac...301234-26.html built by Moscow Aviation Institute OSKBES MAI. «Foton» (Photon). An experimental airplane in 1987

OH if correct

I assume its Open House, so one for all you experts

You will make it easy if you post British helicopters.

You may be partly right ;)

Surely we should only include aircraft which could actually fly? This one never managed it...

A good tip re rotorcraft. :O

It was designed to fly but Newton's Law of gravity won out when tested. If PDR1 cares to post the answer sent by PM it is over to him.

It's the ghastly 'tip jet' Percival P74 which as mentioned above fortunately never managed to get airborne.

I have no pics so open house again.

Well if no one else is playing, how about this one:

Supermarine 508: predecessor to the Scimitar :ok:

Ok, that's near enough the 24 so I'll call it. John got it bang-on - It's the Supermarine type 508 variant of the straight-winged precursor to the Scimitar. This one had the V-tail and other design changes to suit it for the "rubber deck" wheel-less carrier landing trials:

John has the batton

There is some interesting stuff online about the 508 :ok:

Quote:

In the late 1940's, the Royal Navy investigated the design of a flexible “sprung” rubber deck for an aircraft carrier on which an aircraft could land on the underside of its fuselage, without the need for an energy absorbing undercarriage. It was hoped that in addition to reducing the over weight by up to 7%, it would also decrease the number of accidents during landings.

Supermarine produced a design to meet this requirement, designated Type 505 with a thin, straight wing and a V-tail powered by two Rolls-Royce Avon engines mounted on the fuselage sides.

In 1948 however, the Admiralty has second thoughts and a decision was made to fit a tricycle undercarriage instead, resulting in the Type 508 built to Specification N.9/47.

The first Type 508 (VX133) made its maiden flight from Boscombe Down on 31st August 1951 before carrying out further carrier-trials aboard HMS Eagle.

A second prototype (VX136) flew on 29th August 1952. In addition to a slightly larger tailcone to accomodate the proposed tail-warning radar, it carried the planned cannon armament and was significantly different enough to be designated Type 529.

Both the 508 and 529 featured straight-wing configurations and as predicted their speed was relatively modest at 607mph. By the time the first prototypes had flown it had already been decided that a swept wing version would be needed.

The planned third prototype was redesigned with swept wings and designated Type 525, this being the immediate progenitor of the Supermarine Scimitar.

Sadly the only 525 was lost in a crash but the design had proved successful enough to lead into the production of the much developed Type 544.

Specification

Type 508 Powerplant Two 6,500 lb thrust Rolls-Royce Avon RA.3 Span 41 ft 0 in Maximum Weight Not available Capacity and armament Single pilot, four 30 mm cannon (Type 529) Maximum Speed Approx 600 mph

Number built

Type 508 One (VX133) Type 529 One (VX136)

Survivors

No aircraft survive - believed to have been scrapped

A great image showing the size of the beast: the Scimitar must have been a lot of aircraft off the deck compared to the Sea Hawk!

New challenge to follow :cool:

Here we go: getting away from those things that need to run up and down runways to get airborne ;)

Exact model designation, please :ok:

I recognise those hangars! 3-blader so it's the Mk.1.

Definitely more than three blades: Mk 1 what? :hmm:

See post 961. Mk.2 had the stub wings and Mk.3 had four main rotor blades. There's one not far from where the photo was taken.

Your post 961 seems to have omitted the type, as I saw it. Sure it's the Mk 1 but I didn't see you identify the Bristol 173 in that or your latest post?

Jhieminga has the Bristol 173, so over to you :ok:

I believe that's the Lambach HL-2.
