Why is the 737 engine flat on the bottom?

Why is the engine bottom flat? This would prevent the engines from hitting the ground, even if they were larger than previous models. Subsequently, the engines on future 737s were flattened along the bottom. This allowed them to contain a larger fan and turbine without compromising on ground clearance.

Why are jet engines angled?

The results cover the emergency cases in which one engine is inoperative. The results indicate that a suitable jet engine angle in trimmed flight may reduce the total drag, the fuel used, the thrust required and/or maximize the range and endurance.

What type of engine is on a Boeing 737?

CFM International CFM56Boeing 737-800 / Engine type

The CFM56-7B is the exclusive engine for the Boeing Next-Generation single-aisle airliner. In total, over 8,000 CFM56-7B engines are in service on 737 aircraft, making it the most popular engine-aircraft combination in commercial aviation.

How many engines are on a Boeing 737?

two jet engines
The 737-800 is the most common 737NG variant. The Boeing 737 Next Generation, commonly abbreviated as 737NG, or 737 Next Gen, is a narrow-body aircraft powered by two jet engines and produced by Boeing Commercial Airplanes.

Do jet engines turn clockwise?

In the western world, most propellers and fans of turbofan engines turn clockwise when viewed by the pilot, counterclockwise when viewed from the other side, the observer in the airport.

Which direction do jet engines turn?

On most twin or multi-engine propeller driven aircraft, the propellers all turn in the same direction, usually clockwise when viewed from the rear of the aircraft. In a counter-rotating installation, the propellers on the right wing turn counter-clockwise while those on the left wing turn clockwise.

Does Boeing make their engines?

The Boeing Company does not make aircraft engines because it has chosen to specialize and focus on manufacturing aircraft frames where it has carved a niche for itself!

What kind of engines does Boeing use?

Boeing already uses GE engines on nearly every commercial aircraft they build[xii]. Boeing installs GE engines on its 747, 767, 777 and 787 families of aircraft.

How does a plane engine work?

All jet engines, which are also called gas turbines, work on the same principle. The engine sucks air in at the front with a fan. The burning gases expand and blast out through the nozzle, at the back of the engine. As the jets of gas shoot backward, the engine and the aircraft are thrust forward.

What type of plane had engine failure?

Over the past five years, the problem of engine covers detaching due to fan-blade failures that spew parts forward appears to have primarily surfaced on two Boeing aircraft types, the 777 and 737, which use engines made by different manufacturers, according to current and former FAA officials.

Why do some planes have engines above the wings?

That’s about what I can come up from memory, maybe someone can merge all answers into a comunity wiki kinda post.. Mounting jet engines above the wings (see: Antonov An 72, Boeing YC-14) takes advantage of the Coandă effect to increase lift and improve short-field takeoff and landing performance.

Why do planes return to the trimmed angle of attack?

An important concept for pilots to understand is that if the airplane is at a balanced, “in-trim” angle of attack in flight, it will generally seek to return to the trimmed angle of attack if upset by external forces or momentary pilot input. This is due to the longitudinal stability designed into that airplane.

Where are the engines mounted on a jet airplane?

Different jet airplanes mount the engines in different ways. How does the engine location affect aircraft performance? Is one better than the other? Engine location performance-affecting factors: 1. Mounted in the wing root 2. Mounted in pods under the wing 3. Mounted inside the tail or on pods on the rear fuselage

Why did Boeing choose the CFM56-3?

In the early 1980s Boeing selected the CFM56-3 to exclusively power the latest Boeing 737 variant, the 737-300. The 737 wings were closer to the ground than previous applications for the CFM56, necessitating several modifications to the engine.
