Next message: (no name): "T&T: What the hell is a Kort nozzle?"
Hi All,
when I was a youngster (many years ago) my older
brother and I used to play with a 'rocket motor'
for models which I think was called a "JETX".
These little units were basically a hollow tube
that containrd a couple of pellets (of unknown
material) and a "thrust cap" which was basically a
screw-on cap with a small hole to allow the
combustion products to exit in a high velocity
fashon.
They would propel our little balsa wood model
airplanes very nicely, to a velocity that could
assure a flight of much longer duration than we
could acheive with a hand launch.
They offerred, as an option, a 'thrust improver'
that looked very much like the devices shown in
the website refferred to as "xxxx" (I can not
remember the name right now. Sorry for the CRS
Syndrome symptom).
These devices worked. Thrust was improved by at
least 20%, by actual testing of verticle endurance
timing with a stopwatch (high tech in the '50s).
Therefore, the concept of the thrust enhancing
effects of these XXXX nozzles is supported.
OK. WHAT WAS THE NAME AGAIN?????
