Jetex "rocket" motors were
quite popular during the 1940s through the 1970s. Their debut in the modeling
world was in 1948, per the
Jetex.org
website. Unlike Estes rocket engines that used combustion to generate a high
velocity ejection stream, Jetex fuel pellets merely "burned" at a constant rate
while the exhaust was forced through a small orifice in the engine's metal
housing (casing). Also unlike Estes engines, the Jetex casing was reusable and
re-fuelable. Half a dozen or so sizes and thrust levels eventually were
produced. I had a couple of the Jetex 50 engines that got strapped to Guillows
balsa gliders and, to some degree, were made to fly in jet-like fashion. For
some reason I always had a hard time getting the igniter wire wick to keep
burning after it went through the orifice, but was probably my ineptitude since
plenty of people had great success.
