**History of the Yak-54**

OKB Yakovlev almost always engaged in the creation of training and aerobatic sports aircraft: UT-1, UT-2, Yak-18, Yak-18, Yak-50, Yak-52 PM, PS. But the further, the fight with rivals became more difficult, especially with foreign ones. "Zlín", "Extra", "Laser", "KAP", "Pitts" have always been leaders in the world market, demonstrating their technical superiority. They went around the indicators of our Yak-50: in the late seventies, vigorous aerial acrobatics - high-speed angular rotations became fashionable. As a result, we have more compact and light cars YAK-55 and Su-26. In 1984, H. Makagonova, piloting the Yak-55 in Hungary, became the world champion. Two years later this highest title was succeeded by L. Nemkova in England at Su-26.

The main problem rests on the motor. We do not have engines similar to "Laikomingu" or "Rotax". If we consider a whole series of machines, starting from the Yak-50 and ending with the two-seater Su-29, then they have one engine - a star-shaped 360 hp. With it, a sports Yak-54 was built. It is worth highlighting the painstaking painstaking work of engineer Vladimir Popov and designer Dmitry Drach: in the harsh conditions of the current economy, they succeeded, together with the OKB team, to develop a sports aircraft for the latest modification requirements. And the idea to take as a basis Yak-55M for Yak-54 belongs to the General Designer A.N. To Dondukov. The weight of small nuances in the design led to excellent results. The main pilot Andrei Sinitsyn was pleasantly surprised by the new car. Yak-54 turned out to be much better Yak-55M, and its cost price is almost two times lower compared to the two-seat Su-29. And in the characteristics of stalling and reverse flight, he managed to outperform his rival.

To the category of non-ordinary attributed and "Acrobat". This short-winged baby was extremely light, only 700 kg. The engine was still quite cumbersome (half the weight of the device) and had a power of 360 hp. But how original were the layout and aerodynamic solutions. Among the foreign designs, the most interesting was "Pitts" - practically a toy biplane, surprisingly maneuverable, durable, performing dizzying pirouettes around its tail. By the way, the Yakovlevs had a longstanding creative friendship with business people and American designers. In the states, even a magazine called "Yak pilot club" is published.
