A Model for Bomblet Ejection from Missiles.

摘要

Ejection of bomblets from a missile which does not have an active ejector mechanism is studied. A model is developed for this process which yields a measure of ejection time, bomblet position at early times and trajectories. The model involves centrifugal (roll rate effect) and aerodynamic forces. A gross knowledge of the flow field is necessary and an estimate for forces on a bomblet while it is penetrating a shear layer is crucial. It is shown that a bomblet may be trapped in a separated flow pocket. Results from the model are consistent with some observations and have been useful in design and performance studies. (Author)
