I was looking at some old jetex designs and I noticed that they used to sell "thrust augmenter" tubes. These were of a larger diameter than the Jetex unit itself and it was supposed to "augment" the thrust...somehow.
Then I was looking at the Lil Augie and Augie, 2 ducted propulsion designs from the 60's....
So that got me to thinking; I am fully aware of the Krushnic effect... but what if you had a model rocket motor thrusting into a slighlty larger diameter tube, such as air was "rammed" into a scoop such that this slowed down air was directed right along side the exhaust plume.
would this work to increase the actual thrust of the motor?
What I'm thinking of is some kind of ram air induction system ..I know that model rockets generaly stay subsonic, but would some air still be compressed some?
I did some patent seraches and other resarch and there are air breathing solid propellant rocket motors.... but they direct the rammed air directly into the top of the solid propellant rocket motor....
I'll try and get a rough drawing up soon
thanks
