compare the air craft weight&size the engine is seems very small how the engine getting this much power to?

Answer 1

Uh?

Answer 2

You can't judge the power of an engine by looking at it. You have to go by the numbers. The carrier pilot who posted gave some good examples.

If you see an airplane take off and fly away, you will then save yourself a lot of worry if you will just accept the fact that the engine is powerful enough to provide the thrust required to overcome all the drag of the airplane and accelerate it to a sufficient speed that the wing produces enough lift to overcome the force of gravity holding the airplane down.

Look on the internet for pictures of a C-124 Globemaster cargo plane from the 1940s-1950s. The visual proportions of that airplane are all you need to convince you that you have to go by the numbers to know that the wing is big enough to support it and the engines are powerful enough to pull it along.

A co-worker walked through the office pulling a length of string. Someone asked him why he was pulling the string, and he replied, "because it's a whole lot easier than pushing it."

Answer 3

The engine doesn't lift the aircraft and isn't designed to have the power to do so. All the engine has to do is get the aircraft moving fast enough so the wings develop enough lift to make the aircraft fly. To do this, the engine has to overcome the resistance to forward motion. Once the wheels are off the ground the only resistance is the air resistance.

Answer 4

Engines, reciprocal (with propellers), turbo (with propellers driven by jet), and jet (no propellers), burn fuel. Reciprocal engines burn a form of gasoline like the gasoline your car uses. Turbo and jet engines burn something like kerosene. That's where they get all that power.

The reciprocal engine aircraft I flew on and off aircraft carriers in the Navy generated 1550 horsepower each at take off power. Each one of those engines generated more than five times more power than most of the high powered automobiles on the road.

Reciprocal engines for aircraft typically have a lot more cylinders than car engines. One aircraft engine I know of, for the EA1, had eighteen cylinders, more than twice the number of a V8 car engine.

In addition to more cyclinders, a typical high powered aircraft engine uses turbo power. This means the air going into each cylinder is compressed over and above atmospheric pressure. Bottom line, the engine puts out more power than it would without the turbo compression.

Jets also create a lot of power. Their power is measured in pounds of thrust. There is an equation for converting thrust (pounds) to horsepower, but it is rather complex; so I won't bother with it. But check this out:

"The NASA data also includes a few other planes, so let's compare the power generated by the subsonic 747 airliner to a supersonic fighter like the F-4 Phantom II. In this example, the F-4 cruises at Mach 1.8 at 55,000 ft (16,765 m). The aircraft's two turbojet engines produce 11,560 lb (51,430 N) of thrust at its cruise speed of 1,742 ft/s (531 m/s). This combination of force and speed equates to a power of 36,620 hp (27,310 kW)." [See source.]

So, there you are, an F-4 with 11,560 lbs of thrust in each jet engine and going like a bat out of hell produces 36,620 HP of power. Clearly that kind of power can not only keep the airplane flying, but flying at almost twice the speed of sound.

Answer 5

Hehehe. If you want to learn to fly (and I mean serious stick and rudder really *fly*) go get sailplane slapped on your ticket. Once you can fly like the Eagles, then you get to fly *with* them.

There's nothing to beat the feeling of coreing a thermal with a bald Eagle only a couple hundred yards away who's doing the same thing.
