DEVELOPMENT AND TESTS FOR ACHIEVING RELIABILITY AND REPRODUCIBILITY OF SOLID PROPELLANT GAS GENERATORS 600420
The applications for solid propellant gas generators in the Guided Missile field are discussed. Characteristics are related to their applicability in specific areas. Desirable properties of propellant and other gas generator components are cited, based on such factors as the effect of exhaust gases on turbine, gas valves, and other missile components. Design features are described which result in the capability of solid generators to perform reliably and reproducibly after temperature cycling and other environmental tests. Schematic diagrams of a typical solid generator are shown for orientation. Components critically affecting reliability and reproducibility are indicated.
The importance in the reliability and reproducibility picture of various components within the gas generator itself is discussed. Specific items covered include effect of nozzle size and tolerances on exhaust gas mass flow rate, methods of achieving reliable ignition, and pressure drop through the filter and exit tube. Development problems and approaches to their solution are discussed. Among these are achieving dimensional control of propellant grains, developing nozzle inspection techniques, and formulating of process and quality control procedures necessary to insure reliability.
