Sukhoi Shkval Sukhoi Shkval The Sukhoi Shkval (Russian Сухой Шквал, English Squall) was a Soviet project for an interceptor in the Tail-sitter design. In 1960, the young designer Rolan G. Martirossow (who later became chief designer) began his own initiative with a team of 10 people, designing an aircraft of a completely new class - a single-seater, highly capable Tail-sitter for intercepting hunting. Soon the team got permission to work on the project in his spare time and the project got the name Shkval-1 ([Squall-1). At the same time Yakovlev worked at the Yak-36 and Hawker Siddeley at the Harrier. Both designs
Sukhoi-Gulfstream S-21 Sukhoi-Gulfstream S-21 Sukhoi-Gulfstream S-21 was a projected Russian-American supersonic business jet. In the early 1990s, Gulfstream Aerospace and the Sukhoi Design Bureau began a joint effort to develop a supersonic small business jet, code named the S-21. Due to questionable market demand for commercial supersonic air travel, commitment to the project weakened and delays mounted. Gulfstream eventually dissolved the partnership, although Sukhoi continued work on the S-21. The S-21 would be capable of sustained cruise at Mach 2+ and much research and development has gone into the management of the troublesome transonic effects phenomena associated with near Mach 1 air
