Higley Road P.O.

The system will be designed to vary the ejection energy to control the countermeasure eject velocity, using a computed solution from given factors of depth, temperature, weight, and speed. The concepts will include a segmented solid-propellant gas generator, a throttled output gas generator and a gas generator with oxidizer addition to the propellant by-products. Three propellants will be evaluated and compared for each concept. Benefits: The current MK 77 gas generator has a progressive mass flow versus time output with sufficient energy to launch heavy munitions at submarine-rated depth. Using this same gas generator with potentially sensitive countermeasures risks damage due to a high shock pulse. The tailored gas generator to be studied in this program provides less impulse when low force is needed, such as a shallow depth launch, and can be adapted across a wide range of countermeasures.
