Abstract

Focused on the features of stealth, super-maneuverability and supersonic cruise of the future fighter, the authors identified the main difficulties and gave some practical solutions to lift-drag characteristics at sub-/tran-sonic speed, high A. O. A. aerodynamic performances at low speed and supersonic drag characteristics. The authors believed that design goals could only be achieved by studying flow principles deeply, digging up the potentials of present aerodynamic improving measures, developing new aerodynamic concepts, adopting interrelated integration and flight control measures and compromising on the multiple design points.
