Oh, I didn't realize they simply use it to propel it forward by pushing against the air.Kair said:I am not an expert on turbine engines, but I think the Abrams uses the turbine to power the tracks, while this Batmobile uses it to push air behind it like a jet would (the turbine is from a jet too). Pushing air is very inefficient compared to pushing dirt as the Abrams does.Kenjitsuka said:I wonder what the top speed is!
The ultra heavy M1A1 Abrams Battletank is also powered by a turbine engine, and it can go reaaally fast.So you can imagine how powerfull those babies are!
That's indeed a very silly use of the raw power from the turbine.
I figured this turbine power Batmobile was powering the wheels directly, like the Abrams...
I laughed. Hard.Earnest Cavalli said:
Does it even need to be said that I want one? Then I'm only several billion dollars, 2 dead parents, years of training and a continent away from being Batman.
So am I the only one who read the youtube description? Everyone is asking "how fast is it", when the guy clearly states:
That doesn't give you specific numbers, but it gives you a pretty good idea of what it's capable of (you know, assuming that custom frame is capable of withstanding the forces, which it probably is).
It would generate a lot more power, but it would require a heavy drive shaft.Kenjitsuka said:Oh, I didn't realize they simply use it to propel it forward by pushing against the air.Kair said:I am not an expert on turbine engines, but I think the Abrams uses the turbine to power the tracks, while this Batmobile uses it to push air behind it like a jet would (the turbine is from a jet too).

Responding in reverse order:Uriel-238 said:
- You could filter the air, but the filtering could cause a loss of efficiency, in that it requires the air to be drawn through a micro filter that has high resistance.
- Aircraft alloys are more expensive then standard alloys because they require very high BHP steel or to be very light weight. The amount of force an aircraft exerts is quite large and high grade steel is expensive. That's one thing that is used in aircraft engines. Also air planes are generally made out of duralinium (an aluminium alloy, that hardens as it oxidizes) or titanium (fighter jets). How ever, race cars I think are possibly titanium or more likely duralinium, I know that from watching a documentary where they replaced the chassis of the car (usally low/mild steel) with a more lightweight alloy, also some sports cars are made out of
duralinium.
EDIT: Cars do use air breathing engines. The pistons work by bringing in cool air and compressing it, then igniting fuel in it to provide heat/expansion, and the fact that the air has to be cool and compressed is a loss of efficiency for the engine because energy is lost to the radiator used to cool the pistons down. I don't think cars filter the air that they breath in too much as a spark-piston engine doesn't have the same high velocity air intake that causes particle erosion on aircraft. You hit the nail on the head with the fact that the engines like turbines, that have so much more horse power, breath a lot of air. Or a lot more, comparatively.
EDIT: Duralumin. Bloody doctor who google result screwing my spelling check.
He got the engine out of military surplus from an old military drone. I can't actually find that navy drone with the turbine engine so I can't find out if it's engine is one of the following leading to the described results.Kair said:I am not an expert on turbine engines, but I think the Abrams uses the turbine to power the tracks, while this Batmobile uses it to push air behind it like a jet would (the turbine is from a jet too).

- Turbojet : Pushes air
- Turbofan : Pushes air
- Turboprop : Turns a propellor, you can use this to turn a car's wheels instead. You can modify it to act like a turboshaft engine.
- Turboshaft : Absolute best case turbine engine for a ground vehicle, the abrams uses this, basically it uses the high pressure air to turn a fan that turns a crank that turns the wheels. Using air to turn a fan might seem bad, but it's quite efficient and powerful.
The guy stated that he learned about turbines. If I was going to get a military surplus turbine engine to put it in a car, I would get turboprop/turboshaft and modify it as to my needs.
Also, the message states:
"The engine powers the rear wheels via a semi automatic transmission and is driven like any other conventional production car"
So yeah, it's not pushing air to move.
