Abstract
A system for determining the proper instant of time to launch an object, h as a target or torpedo, from an aircraft to cause the object to impact a water surface at a predetermined nose-down angle, thereby preventing structural damage due to high impact forces. The system utilizes signals produced by instrumentation representative of the aircraft pitch and angular rate of pitch. The desired launch altitude and predetermined impact angle are physically set into the system by means of adjustable voltage sources. These parameters are processed in the system such that the system forms a complete electronic analogy to the physical laws which govern the motion of the free falling object. In operation, the system continuously computes the predicted impact angle based on the instantaneous inputs of the aircraft's altitude, pitch angle and pitch rate. It then compares the predicted impact angle with the predetermined impact angle. Whenever the predicted impact angle exceeds the predetermined impact angle, a launch signal is produced to release the object.
