Kosdon TRM Rocket Motor Hardware

KOSDON TRM reloadable rocket motors, also known as Truly Recyclable Motors, are machined from high strength seamless 6061T6 aluminum tubing. The forward closure (delay & ejection charge head) is machined from 6061 aluminum and the nozzle is of graphite, which is good for at least 20 firings! The forward and graphite nozzle are sealed to the casing with o-rings of high temperature resistant silicone rubber. The o-rings are good for many firings. The nozzle doesn't have to be removed between re-firings over a two or three day period.

The design philosophy of the KOSDON Reloadable (TRM) is elegance, simplicity and functionality. On each end of the motor casing an internal groove has been precision machined. The grooves are for snap ring fasteners which hold in the nozzle and forward closure. The delay element does not have to be under compression in order to seal nor in contact with the propellant grain to ignite.

KOSDON Motors are manufactured in SAE sizes which closely match the metric standards used in model and high power rocketry. The 1" motor will fit into a 29mm mount with an adapter available from KOSDON. The 1-1/8" motor measures 28.575mm, and fits into a standard 29mm mount. The 1-1/2" motor measures 38.100mm and fits into the standard 38mm mount. The 2-1/8" motor measures 53.975mm and fits into the standard 54mm mount.

1 - Motor Casing
1 - Re-Usable Graphite Nozzle
1 - Forward Closure (Either Delay Or Plugged)
3 - Snap Rings
