Abstract

This research work present mainly on various thermodynamic aspects of solid propellant gas generator for aircraft application. A gas generating device is hot gas generator that creates high temperature and pressure combustion gas on burning of the propellant inside the cartridge case. Thermodynamics is the branch of science which deals with energy transformation into work and vice versa. These devices are filled with energetic materials (EMs) and used to perform a critical operation in an emergency under adverse conditions. It releases the energy very quickly. Gas generator has a large number of applications and its demand is continuously increasing in the areas of aerospace and aeronautical technologies. A data acquisition system is used to record time to maximum pressure (TPmax) and maximum pressure (Pmax) generated in closed vessel (CV) for solid propellant gas generator. A double base (DB) propellant is used as medium for gas generation. The purpose of this research paper is to establish the various relationships and to determine various thermodynamic properties for solid propellant gas generator used in aircraft application. Specific heat of propellant varies from 0.25 to 0.35 cal/g/0C, calorimetric value 925 cal/g, force constant 1052 J/g, co-volume 0.989, flame temperature 2944 K and etc. were experimentally determined.
