1974, to our surprise, China obtained the patent of Speer's military engine, which was the top product at that time. Although we applied for a patent, China's new industrial materials and other technologies were too backward at that time. It was not until 20 13 that this localization road was completed, and it was equipped on the JH -7 Flying Leopard fighter, which also made Flying Leopard a main fighter completely independent of imported engines.
Extended data:
Flying leopard has good flying performance at low altitude.

The swept upper wing with medium aspect ratio has serrated leading edge and obvious dihedral angle, the outer wing has aerodynamic torsion and the wing root has rounded corners. Oblique fixed axis full motion, middle and lower flat tail, large swept back, single vertical tail.
