| Abstract: | The motion model of "zero-zero" jettison of aircraft canopy was developed to get the trajectories of the jettisoned canopy and the perfect jettison angle, and the agreement between model prediction and experimental measurement result was satisfactory. The rule of the air input of the underside cavity was also discussed in order to get the pressure curve .The result of all the research can be used to predict the trajectories of aircraft canopy in the "zero-zero" jettison. |
