Fluid supply systems

Abstract

The invention relates to a fluid supply system and seeks to provide a simpler, safer but reliable system than at present known. The fluid supply system comprises a multi-charge solid propellant gas generator and a fluid expulsion unit integrated into a single unit, the gas generator being provided in a cap (8) for a chamber (1) having a gas portion (3) and a fluid portion (2) and a movable partition (4) between these two portions operable to expel fluid from the chamber when the gas generator is rendered operative. The system also comprises ignition control means (22) operable to control the ignition of the solid propellant charges (13) when required to give a fully controllable system output. The system can be designed for supplying under pressure fluids such as hydraulic oil, fuels, oxidants and water and is particularly useful in aerospace applications.
