Abstract:
A totally new concept for providing emergency auxiliary hydraulic and electric power for commercial and military aircraft is described. The approach is ideally suited for meeting the demands for secondary power during an all-engine-ou t situation.

The concept is a totally self-contained, monofueled, turbine system. It consists of a constant speed turbine deriving its power from a monofuel, which is fed to a decomposition chamber and controlled by a unique fuel control system. Fuel is stored hermetically until required. It is then supplied via a positive expulsion tank system yielding attitude and altitude independent operation. Explanation is given specifically about system philosophy, fuel selection, fuel tankage, gas generator, turbine power conversion, control system and ground checkout.
