The report presents the results of an experimental study in which aluminized and non-aluminized composite solid propellants were ignited under different environmental conditions. Ignition was achieved by radiative, convective and chemical heating. An optical system operating in two narrow wavelength bands was used to detect the onset of ignition on and near the surface of the propellant. It was found that ignition delay time was dependent on the wavelength used for detection, the method of heating, and other environmental factors. The implications of these results are discussed in relation to existing ignition theories, and recommendations are made for further study.
