Myasishchev M-50

Although built only in prototype form, this design by Myasishchev was an extremely advanced turbojet-powered bomber with supersonic flight capability. In configuration, the Myasishchev M-50, codenamed 'Bounder' by NATO, had a shoulder-mounted cropped delta-wing, a conventional tail unit with all-swept surfaces, and landing gear comprising retractable tandem main units mounted on the fuselage centre line, each with a four-wheel bogie; while retractable outrigger balancing struts, each with two wheels, were mounted near the wingtips. The slender area-ruled fuselage provided pressurised accommodation for a crew of three and incorporated a large weapons bay. Power was provided by four wing-mounted Soloviev D-15 turbo-jets of 13000kg thrust in underwing pods. First flight of the M-50 is thought to have taken place in 1957, and the last of several prototypes, re-designated M-52, took part in the Soviet Aviation Day fly-past in 1961. With the two re-heated outer engines relocated to the wing tips, the M-52 was powered by four Kolesov ND-7F or VD-7F turbojets, with an afterburning thrust of 18145kg. Considered formidable by the West, the M-52 was estimated to be capable of Mach 1.83 or 1950km/h at optimum altitude.


Although the principles of 'waisting' the fuselage to achieve the area rule effect were widely known by 1955, they were not applied to the M-50, leading again to high drag.

The M-50 was almost exactly the same length as the XB-70, with a slightly longer wingspan, but less than half the wing area.

The wing was swept at 50 degrees, regarded by Western experts as a poor choice when combined with a high wing loading. The wing was generally thought to be too small.

The wingtip engine location contributed significantly to drag. The pylons which attached them to the wing underwent significant modification between public appearances.

The Bounder was intended ro carry a weapons load of up to 20,000kg.

The M-50 Bounder actually first flew on October 27, 1959. It was the subject of a false December 1958 report in Aviation Week about the Soviet Union getting a nuclear-powered strategic bomber into the air, but it would be clear that the M-50 was fueled by kerosene. The M-52 was similar to the M-50 but added an extra horizontal stabilizer on the top of the rudder and had a cockpit where by crewmembers sat side by side.

The outside engines didn't feature afterburning.

Quite similar to the B-58.Sadly it didn't go into production

A fine Russian aircraft - could be said a shame that it wasn't put into service???!!! Imagine these being snapped over the North Atlantic by Royal Navy Phantoms /Lightnings or Saab Drakens /Viggens during the Cold War instead of the familiar (But equally impressive) 'Bear'.

Really near to some never built American interinal projects (early B-58). Isn't it?


Do you have any comments?
