I like fast
model aircraft, which the local model aircraft clubs refer to as guided
missiles, as they expelled me........
Some of the
pictures on this page are big and will take a little while to load. No
One of the
gas turbine motors shown below is actually a bit on the big side for model aircraft,
as it makes 70bhp (shaft) and over 100 pounds of static thrust.... It is a
Plessey Dynamics Solent, gas turbine starter or gts about 18 inches long.
There are more pictures of
this gas turbine lower down the page.
It started life as a military APU (auxiliary power unit) on a full size
Phantom F4 fighter Jet. It was used to start the main engines primarily,
so it is just a starter motor! This device was big and bulky with its own
fuel and oil, and electric starter system all built in. The gearbox, and
secondary power take off turbine was all removed and machined away,
leaving a light powerful pure turbojet jet engine that you can hold in one
The picture above is a 380mph
Pulse-jet powered delta, that works entirely differently from gas
turbines. This one plane has no undercarriage, and takes off with the aid
of the bungi cords stretched out to 'ping' it off the ramp. Pulse-jets are
fearsomely loud, to the point of blurring your vision and making you feel
Basically they are a simple
empty tube with a fuel injector and a reed valve in the front. No throttle
and they start and stop instantaneously, and this also makes you jump!
Radio Control and good piloting skills are essential!
Above another fast pulse-jet
delta by a Dutch team at Evington. All these powerful pulse-jet engines
are home built, from a drawing that you can download
as designed by the Dutch team. This is a well developed unit, but requires
careful construction using rolled 0.5mm stainless steel sheet, and spot

jet model aircraft.
Above is a small gas
turbine, home built, Called a "Shreckling" after the designer,
actually sat running on my bench in my bedroom. It might look peaceful
here but it cleared us out the room pretty quick.

Back to the bigger one first
seen at the start of this page the Solent after conversion to thrust only.
This may finish up propelling a wheelchair! I kid you not!

This is to show the size
difference between the Solent, and the little Shreckling motor.
Finally the end of a very
big page! This is a photo of noise, the plane can just be seen behind the
guy bent over it. Pulse jets are VERY loud. The guys starting it have ear
plugs, the crowd do not - look at their faces, and fingers in ears!
