Can't believe I'm the first to think of this!!! (maybe not surprised, though).



The rotary engine can achieve additional thrust by directly injecting fuel at the engine exhaust (step 12 in diagram). The process, we'll call afterburn, gives the RX-7 a rocket-like boost as the fuel ignites in the exhaust chamber. The tradeoff is higher fuel consumption, a greater amount of heat, and consequently, greater visibility to the enemy. https://www.nopistons.com/forums/pub...1047683517.gif



I'm planning on removing the sub woofer box that currently occupies the hatch in my seven and installing a fuel cell. The fuel cell will have to be SAE certified to AMS 3269A, the (jet) fuel might be a little more expensive but that's just another trade off. Now for the hard part, to control my variable nozzle (Mil-I-27191C) fuel injectors (mounted a few degrees clockwise below the spark plugs) I'll have to fab some sort of circuit board using TTL components similar to that of MOSFET technology. What the circuit will do is take feed back from fang factor, ambient air temp, boost, and combustion temp using a quad-output/input switching sensing power supply (A-A-50764) and determine the level of afterburn that will be safe for given situation. Estimations on power increase can't be stated at this time, still in R&D. https://www.nopistons.com/forums/pub...#>/gotrice.gif



The cat will have be removed https://www.nopistons.com/forums/pub...#>/biggrin.png , system will probably have to be used with water/alcohol injection (maybe nitrious) to keep intake temps to a minium...IT'S GUNNA GET HOT IN THERE!!!

Whats the point? melt the turbo?

you must have alot of time on your hands to come up with such a think. That seems kinda dangerous.

no - use extreme heat to spool that mothafawker at lightening speed!

ROTOR KILLER, im anticipating a post in a few weeks explaining the death of a member, apparently attempted to light his farts on fire while yelling "AFTERBURNER" in the presence of an open container of highly explosive jet fuel.



farts are for stinking not lighting



umm im off topic, good luck testing and tuning. wear a helmet

is this serious? I honestly can't tell if it's supposed to be a joke.

pengaru 10-17-2003 07:33 PM

i had to check if it was done april 1st

This won't work. IT's called anti-lag and it destroys the turbine wheel of an exhaust, not to mention mega-accelerated bearing wear due to sharp thrusting, etc.

It technically will but won't. I've seen at a few tractor pulls (real tractors) and they place another fuel injector before the turbo (in the manifold) and spray fuel while they are pulling. They go from 0-60 psi in a matter of seconds. If any body knows about jet engines, it kinda works like that. But the downside, unless the turbo is cooled alot, the turbo usually is fried after a pull or two.

CONGRATULATIONS!!!!!



We have a winner! I was researching the Pratt Whitney F119-PW-100 engine...hence "afterburner" and more "visibility by the enemy"...and just put rotary engine in place a few times.



This was a total joke, but obivously I'm not very funny. Yeah I'm really going to take out my sub woofer to make room for a JET fuel cell https://www.nopistons.com/forums/pub...>/rolleyes.gif but I guess none of you know me, so...



My thought on way this wouldn't work is a jet is powered off exhaust, where in RX-7's we have a drivetrain.



I'll keep my rambling thoughts to myself from now on...
