Tourbillion


Recommended Posts

And so, the last tourbillion with wooden wings has been launched two days ago and here is report:

1. The fuse (see Fuse Machine topic) worked perfectly.
2. The composition burned fine with rich spark spray.
3. The spin speed looked just about right as well as humming sound.
4. The device did not fly.

Possible reasons of failure to fly:

1. Propeller wings angle too low.
2. Exhaust hole eroded and widened too quickly.

Overall, the device looked seriously efficient but performed poorly. Next one should have propeller even more twisted and we'll see what happens.
Now, do not be too critic about humble me....

A week ago I fired another one with wooden wings, this time with wings twisted at substantially steeper angle...I thought it would help but it didn't.
The blody thing did not fly! It spinned all around the concrete floor sprinkling white sparks and humming like mad, but it couldn't lift off.
The nozzle was definitely too wide. This tourbillion was rammed almost half a year ago and the composition could be deteriorated by the time, don't know.
Anyhow, the shame was on me again as my cousines sons were expecting some performance...

No comments, please.
