I'm sorry if this is stupid for me to ask but would really like to know.

Do planes and Boats Use something different? Or is it just the same type of engine?

Planes use jet turbines, which operate differently to internal combustion engines.
For boats, yeah they also use inteneral combustion engines sometimes.

Seems like any craft can run a turbine - missile, helicopter, aircraft, tank, car, boat.
So versatile.

they are extremely versatile in converting gobs of fuel to power. Not efficiently, but they are light weight in terms of HP per pound. They also have long MTBF compared to reciprocating engines.

You could put an airplane on an aircraft carrier but turn the plane around on the catapult. Get the engine at full power and see how far down the deck the airplane stops once catapulted. Would this give you some kind of dyno reading and stuff?

Speaking of putting the wrong kind of motor on the wrong vehicle, this guy is putting a jet engine on a pontoon boat! Imagine you're just having a peaceful time fishing and this dude is barreling down the lake with afterburner at full tilt, on his pontoon! :D

Jay Leno has a motorcycle powered by a turbine engine that Bell uses in their 206B/L series helicopters.

You can't put a car engine in a plane
I've been flying planes a lot lately. For planes, the biggest issue is regulation of approved fuels and engines for a particular aircraft. Currently, aviation sticks to Jet A or AVgas engines and they are defined as piston or turbine engines with strict guidelines for certification. If you have an experimental aircraft, you can get away with more, but can't fly it in the same places or over populated areas. Until the FAA grants non AVgas engines clearance, there aren't many options.

This company is making a conversion to run off flex fuel, a lighter aluminum chassis, and AVgas too, but I have no idea what they'll have to do for the FAA to approve their design.


You can use just about any engine in a boat. Inboards are basically car engines. The catch is that they often are coated with marine grade paints, grease, and sealants. Most ocean-going vessels are powered by diesel engines. I know quite a few sailboats I've seen had smaller tractor engines due to their 20-30hp, compact size, and superior fuel economy. Of course, if you want speed....you can easily get a 300-500hp engine. It just takes a lot of balancing power along with prop size, pitch angle, boat weight, etc....to avoid prop cavitation and general poor performance. Point is, there's less to screw up on a boat than an aircraft, but still can be a lot to it.
