Abstract

Abstract: Aircraft canopy trajectory of fighter F/A-18C was successfully simulated with solving the Reynolds-Averaged Navier-Stokes equations and the 6-DOF motion equations based on the moving grid technique. The effects of trajectory and the states of the canopy caused by different positions of the center of gravity of the canopy were analysed. The conclusion was educed that the retrusive center of gravity could cut the period of the jettison and optimize the flight trajectory.

Key words: canopy, Navier-Stokes equation, 6-DOF motion equation, center of gravity, trajectory
