Hi Paul,

Paul:
" For the new guys this is what the TTC aircraft  looks like.

 No cowl because  aero drag is down in the noise if you are able to
 climb vertically."

What do you mean by this statement? What has noise got to do with it?

Paul:
" In theory we can at 175 MPH [straight up].  The slip stream does a good job of
 cooling the turbo."

You actually fly with no cowl? And this cools the turbo just by hanging out in the breeze?


 650HP under 1000 pounds.

Really?

Yes.

It is a slang expression in scientific circles used when recording data.
Electronic sensors put out electrical static and it is called noise.
It is electrons bouncing around in the device and  the wires when current flows.
This is at very low voltages. Any time you are recording a signal
or data it is always there but if the signal is significant you don't see it.

Turn the gain up on an amplifier with a microphone attached in
a very quiet room and you will hear noise. It comes from the
electrons bouncing around in the microphone, amp and wires.

Another example is the squelch in an aircraft two way radio.
The squelch is set to a level that cuts it off.

Here is a low res  video of the TTC in a test flight up in the desert.
We had a lot of tuning problems we had to fix and spent months
working with the Motec. Finally gave up and put a manual
waste gate on it. The first time we ran that configuration it fixed it and it ran
three or four times better :-)

In fact the boost ran away and hit 100 inches of Hg!!!!!

That would blow the cylinder heads off an aircraft engine right
through the cowl sheet metal. That level of BOOST does NOT phase a
Wankel rotary.  That is almost seven atmospheres!!!!.

ROTARIES DON'T BLOW UP !!!!!!.

 Even the silicon nitride apex seals DID NOT FAIL.
