The arc image furnace is a laboratory device which may be used to ignite rocket propellant, simulating the conditions of overall heat flux and pressure levels obtained in the rocket motor. Ignition in a motor is usually initiated by a pyrotechnic device which produces a heating effect mainly by conduction of heat by hot particles impinging on the propellant surface and convective heating from the hot gases flowing over the surface. There is only a small proportion of the heat transferred by radiation from the igniter products. In the arc image furnace, however, radiant heat is the means used for igniting the propellant. Thus it is not an absolute test of ignition delay, but it gives an indication of the delays which may be expected from a solid propellant.
