Keywords: aircraft combat effectiveness

The relationship between aircraft configuration parameters and combat effectiveness is investigated by means of a computer aided aircraft design program developed in our university. The study shows that when the take off weight of aircraft is constant, only 20%-50% of improvement of aircraft combat effectiveness can be made with performance improvement, while more than 150% of combat effectiveness improvement can be achieved by using advanced radar and missiles. The enhancement of combat effectiveness is always the goal of military aircraft design. The combat effectiveness is related to many factors, such as the aircraft configuration parameters (take off weight of aircraft, payload, engine thrust, specific fuel consumption, wing area, wing aspect ratio, wing thickness ratio, wing sweep angle, wing taper ratio and other geometric parameters), the radar parameters and missile parameters. In this paper, based upon an aircraft improvement design, the relationship between aircraft configuration parameters, radar parameters, missile parameters and combat effectiveness is studied with the computer aided aircraft design program developed in our university[1]. Made were also the optimization of wing geometry and sensitivity analysis of the wing geometry, radar parameters and missile parameters.
