Now the "weird" thing was NO comments were being displayed at ALL the LAST time I checked :o)

Great ATR stuff... now why not build one and fly it?

John Bossard

DougGard,
Funny you should ask…
Flight test data with an ATR would be quite persuasive in convincing folks of the advantages of this propulsion engine. But it’s a sort of “chicken-and-egg” thing.
Currently, there are plans in the works to test fly some ATR derivatives.
Also, its worth mentioning that it is believed that the soviets had a sea-skimming anti-ship missile that was powered by an ATR engine, although this rumor has never been confirmed to my knowledge.
Anyway, stay tuned.

This is a good patent re ATR using solid propellant.
U.S. Patent 4096803 http://www.google.com/patents/about?id=dw43AAAAEBAJ&dq=4096803

Huu,
thanks for this patent reference. I am indeed of aware of this ATR concept, and it is in fact referenced in a few of mine and others ATR papers. We call solid propellant ATRs "SPATTERS", i.e. SPATRs.
Although their performance is the lowest of all ATRs, they offer some logistical benefits and what we call "wooden round" attributes.
I do appreciate all references to ATR related concepts, patents, etc.
