I know the jet turbine thing is just based on movie reality.
But is it possible to put one in real life?
Can a jet turbine be set in front of the vehicle like that and have the exahust(afterburner) not shoot out diirectly like airplanes?
In the bamtobile, the driver's cockpit seperates the turbine and the afterburner. So is it possible to channel the massive jet air intake around the car without frying the cockpit?

Never say never because anything is possible. However, it’s not very practical or even very feasible. Afterburners (augmenters) work by reintroducing fuel and ignition into the turbine exhaust gases. Simple put it's a contained explosion behind a jet engine. To duct the exhaust gases from the back of the engine around the cockpit and back into an afterburner would cause the engine to lose a lot of its original thrust. To use the thrust and afterburner to propel the car would work well on a drag strip (Like the Lava Machine) but would be useless on the street. The noise created by the jet engine alone would be enough to drive you crazy. Now that being said could a jet engine be used in a car? Yes it can and has been done. The common configuration is to use what is known as a Gas Turbine Compressor (GTC) or an Auxiliary Power Unit (APU). These small jet engine work real well for creating compressed air and do pretty good with creating shaft horsepower or brake horsepower. These engines are also used to turn reduction gearboxes and could be configured to connect to a transmission and used like any conventional engine. Also the heat created in jet engines reaches as high as 1000 deg Celsius in the combustion section in some engines, higher in others. Usually the exhaust gas temperature is cooler but probably still extremely high. Again they are very loud and use a lot of gas. So, can it be done? Sure, but I wouldn't want to be the person doing it. Good luck if you get it to work I want to see the pictures.

Thanks for detailed explanation.
So getting back to the question, currently the batmobile jet turbine configuration would be impossible and impractical then right?

| its possable if u got the money, but highly impratical, becase u would never really be able to use it.

I'm sorry the excessive detail. I'm a jet engine mechanic. Let me put it this way. It is possible with enough money, the right parts, and by someone who has a large team of qualified builder, but extremely impractical. I say go for it. Jax

OK folks check this out. I was just looking at my AMT model of the 1989 Batmobile and it seems that it is possible. The bottom of the model has the engine connected to a transmission and the exhaust vented under the car. The side intakes feed a Ram Jet style engine. This may bet a little detailed. Years ago when Chuck Yager was trying to break the sound barrier there were aircraft called the X-series. Yager had the X-1, etc. These aircraft were dropped from very high altitudes and as air rushed through the aircraft intake fuel (and solid rocket fuel) was ignited. This created an afterburner affect. The rest is history so to speak.
Now, back to the Batmobile. After looking at the bottom of the model you can see that the 2 side intakes do feed a Ram Jet type of engine. Here's the catch, the car would have to be already moving to have enough air pressure created in the rear engine for it to work. This set up would make it one super fast car and I for one would love to see someone build it. "If you build it they will come." I'll be there..... and I bet most of the people on this board will be there too.....

Some of the jet race cars use J79GE-15 motors. It would take up most of the cockpit. You could not carry enough fuel for a sustained run for any extended period of time. You could use a small JFS or EPU for the jet sound and could push the car around town.

Jax,
I really appreciate your answers.
But could you rephrase them in layment's term.
Half the technical things you said just passsed over my head.
Thanks and sorry.
