VINTAGE JETEX MODEL MOTOR + FUEL PELETS

IN USED CONDITION UNTESTED

Jetex engine was a type of solid-fuel rocket engine produced for model aircraft. Originally developed in 1947, by Wilmot, Mansour & Company Ltd of Southampton, it was first demonstrated in early 1948, Aeromodeller featured Jetex power on front cover. The first motors were the Jetex 100 and 200, with the more powerful Jetex 350 following in November 1948. The most popular motor, the Jetex 50, was introduced in May 1949, along with kits for a model plane and model car using Jetex power.

Jetex engines were powered by a solid pellet of guanidine nitrate, which burnt to release a variety of gases in copious volume, leaving no solid residue or ash. Thrust developed was fairly modest, suitable for horizontally launched flying models rather than vertically launched rockets. exhaust gas was not excessively hot, which is a safety advantage. Fuel and wick to ignite the pellets was manufactured by Imperial Chemical Industries (ICI). The engine casing was made of an aluminium alloy and was reusable, new fuel pellets and ignition wick being a consumable that could be bought and used in the engine.


Compared with modern Estes-type rockets, the Jetex is quite different. It has a much gentler, cooler exhaust, so flight characteristics tend to feature gradual acceleration rather than firework-like performance. The cooler exhaust is easier to handle and does not require extensive flameproofing of the airframe. However, the fuel is more toxic and requires special handling to keep it dry and in working condition
