Abstract:

The report is aimed towards determining the effects on catapult performance of using it to propel a live load. The report describes how an analytical model is built up using a previously developed lumped parameter representation of the human body and ejection seat together with a simple direct stroking catapult. Using this catapult, which is characterized by a sinusoidal type development of propulsive force, the difference between the live load and an equivalent rigid load is, in fact, rather small. The importance of the work described in the report is considered to be rather in the development of the model, which can be used for a wide range of similar problems, than in the results of the small number of problems tested.
