Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Yakovlev Yak-1000 was a Soviet supersonic technology demonstrator intended to evaluate the aerodynamic layout and field performance of the cropped delta wing discussed in captured German documents in combination with the new Lyul''ka AL-5 turbojet. The tandem undercarriage proved to be unsatisfactory and there were serious flight stability problems related to the delta wing, enough so that it never flew after an accident during taxiing tests. A June 1950 Council of Ministers directive ordered Yakovlev to develop a supersonic fighter that used the 50 kN (11,000 lbf) Lyul''ka AL-5 axial compressor turbojet. Based on a recommendation from one of TsAGI aerodynamicists, Yakovlev was directed to use the rhomboid or cropped delta-shaped wing covered in captured German research. The directive was extremely ambitious as it required the maximum speed to be Mach 1.7 at a time when the world speed record was barely over the sound barrier.
