Research on effect airwake acts on glide performance of carrier-based aircraft

The kinematic model of carrier-based aircraft was established. The airwake model described in USA military standard was introduced and analyzed. A landing simulation system was build based on the kinematic model of aircraft and airwake model. Numerical simulation was carried out to research the effect that airwake acted on the flight performance of carrier-base aircraft. Simulation results show that the gliding track of aircraft affected by airwake is lower than reference gliding track, which reduces the landing safety. The random component and free-air turbulence component of airwake own the dominate part of effect, the steady component makes contribution too, the periodic component acts little effect on aircraft. Airwake affects flight performance of aircraft by putting effect on the aerodynamic force of aircraft but not aero dynamical moment.
