Description
This motor was originally used to tow a specially constructed net of Cordtex (Primacord), used for demolition purposes. The motor was originally called Motor, Rocket, 5 inch, Cordtex Net, Mk I. Proposed new nomenclature for the motor is Motor, Rocket, 5 inch, No. 3 Mk I.
The motor consists of a steel cylinder, threaded at each end to receive a pressure plate. The pressure plates are threaded internally, the forward one to receive a pressure plate plug and obturator, the after plate to receive the venturi. Two distance collars are beneath the pressure plates to position the cordite propellant grain, which is castellated at the forward end to receive the igniter.
