Experimental studies of the ignition of a solid propellant in water

The ignition of a solid propellant in water by means of an unsealed system of ignition in the form of an open channel with a heating coil placed in th e channel is considered. The ignition system operates according to the prin ciple of creation of extreme conditions of water boiling in the channel wit h heat supply from an electrical heater. It was established visually that t he heating of the walls is preceded by a preliminary period connected with the change in the state of aggregation of water. The system was tested on s olid-propellant specimens.
