Sorry - i used the translation - programm.
Im searching informations, pictures and measures for my new book wiriting project about the 1" Coffman startercartridge. Feel free to contact me!
It looks like a Cartridge Electric Engine Starter 35gr No 7 Mk 1. Length is 4.3 inches. Outside diameter (of the base) is 1.05 inches.
Main charge is a single tube of cordite. A priming charge is of cordite pellets.
Herewith, a diagram of the Coffman Starter as would be used on an aircraft utilising a Rolls-Royce Griffon aero engine(s).
I had previously assumed the propellant was consumed within the case, this however is not situation. The propellant is ejected from the case and is stopped by the 'Nose Grid' where combustion is completed.
He is looking for any information on the cartridges and their variations as well as any available documents on them. Photos of the cartridges are also welcome.
