HYBRID INFLATION MODULE DISSOCIATED ENERGETIC MATERIALS / ISRS

摘要

In the context of a contract in collaboration with Alcatel Space, PyroAlliance has been charged to study an inflation module of a SAR antenna permitting its setting under pressure during 10h. This project deals with the feasibility of a subsystem composed of:o Hybrid gas generation technologyo Driving by an oxidiser flow regulation systemo A module appropriate to the redundant free air is implemented notably to ensure the draining at the end of working.O Besides in order to answer the performances and environments formulated by Alcatel, a cooling module is designed to minimize the gas temperature.The Hybrid propulsion is based on an erosive combustion of a fuel block subjected to an oxidizer flow. This pyrolysis process takes place on the surface of the fuel and the decomposition gases are then burned in an oxidiser stream. In order to start the reaction, the oxidiser/fuel pair must be heated up on contact with ignition system gases.The main advantages of this technology are:o When the system is not active, it is not considered to be a standard energetic object (I.e. pyrotechnic). This reduces the operational constraints.
