Yakovlev Yak-36

Development of a V/STOL fighter for the Soviet navy's new 'Kiev' class of aircraft-carriers began during the early 1960s. Intensive studies bore fruit in the shape of a number of Yakovlev Yak-36 "Freehand'"research aircraft, with a bicycle undercarriage under the fuselage augmented by wingtip outriggers. The aircraft is believed to have been powered by a pair of 36.78kN Koliesov engines, each with a rotating nozzle. These gave a tremendous thrust margin, and powerful autostabilisers gave a rock-steady hover, using reaction control 'puffer jets' in the tail, wingtips and at the tip of a long nose-probe. The Yak-36 was not an operational aircraft, although it did lead directly to the Yak-38.

Luna, some fast checking shows that the Yak-36s used R-27-300 engines. Dunno if accurate or not, though.

He would be interesting to know with certainty which were the motors
used in the prototypes. they were Tumanskii R-11, R-13 or R-27? My
opinion is that the last one is turbofan and at the time of the Yak-36
they did not exist.

Do you have any comments about this aircraft ?
