Stupid Question, Do Planes And Boats Use Engines Just Like Cars?

[Gizmo j]

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?

You can't put a car engine in a plane

The marine propulsion systems market is driven by the need for faster, cleaner and fuel-efficient engines. Less carbon-emitting alternatives are critical.

Pssst.... maybe someone should tell the OP about Google.

You're not fvcking sorry at all don't lie.

Also pretty much everything you post is a "stupid question".

Nothing better than a Yamaha boat engine in a Ford or Volvo!

my teacher told me there's no such thing as a stupid question

Flash Gordon loved freedom so I wouldn't be surprised if his space ship burned fossil fuel.

That's not true. There have been many examples of automotive engines retrofitted into aircraft. That doesn't mean it wasn't a typical Gizmo question though.

You got left behind huh.

Does anyone have will it takeoff thread bookmarked? I feel op needs to read that.

Superman pushes planes through the air. Aquaman pushes the boats. Ground vehicles use magic. The gasoline is just for the vroom vroom sound.

This thread kind of makes me want to Chevy V8 big block swap a Cesna. Maybe add twin turbo.

Imagine trying to bring a plane on a dyno.

Someone fitted a V12 Rolls-Royce Merlin (sans turbo) into a RR

They are too numerous to mention there are Subaru engine conversions, there was a whole slew of VW engine powered home builts. There are automotive diesel engines that have been converted for aviation.

Rotary engines (think Mazda RX7/8 Wankel) are somewhat popular in custom gliders and other lightweight aircraft because of their power to weight ratio , compactness/simplicity, and reliability when properly maintained

Typical car engine isn't really optimized for the same requirements of aircraft: more extreme emphasis on power to weight ratio, reliability, and also different powerband

Something like a typical Cessna probably has the closest thing resembling a "car" engine in that it's a similar style inline reciprocating piston engine but special built for purposes of aviation

Old aircraft often used "radial" engines which were reciprocating piston engines but with the cylinders arranged radially.

Almost any plane you fly on commercially today will be using some form of turbine ("jet") engine, even if it has a propeller- turboprops are the most common for shorter distance regional flights, which is essentially a turbine engine powering a propeller.

Larger planes like your 737s use turbofans, which are similar in concept with a turbine engine powering a "fan" but have the fan internal to the engine nacelle and thus can feed the bypass air back into the exhaust stream to gain more efficiency. The large fan in front of the engine is what's producing the vast majority of the thrust. This style engine is generally incapable of breaking the sound barrier, but they can be very efficient at cruising just below it

Turbojet engines (that are propelled by the engine thrust alone and what the layperson might think of as a "jet" engine) would be those found in military aircraft like fighter jets, which may also incorporate an afterburner which is just a way to throw fuel economy out the window for a bit of extra thrust by dumping extra fuel in the chamber downstream of the exhaust turbine. Since the velocity of the exhaust is so high they can be capable of speeds far above sound barrier

Likewise there was at least one prototype for a turbine powered car.
