What are the advantages of fuselage mounted engines?

Advantages of fuselage-mounted engines:

• Low moment of inertia in roll.
• Lower overall surface area, thus lower friction drag, when compared to podded engines.
• Precompression of the forward fuselage can be used to increase supersonic thrust.

Why are engines mounted under wings?

Structural strength. Wings want to bend upwards as lift increases, and to counteract this wing bending relief, fuel tanks are in the wings and engines are mounted under the wings. Due to this wing bending relief, much larger and heavier engines can therefore also be used.

Which type of jet engine is best?

Compared with a turbojet engine, the turboprop has better propulsion efficiency at flight speeds below about 500 miles per hour. Modern turboprop engines are equipped with propellers that have a smaller diameter but a larger number of blades for efficient operation at much higher flight speeds.

Why do business jets have rear mounted engines?

The rear-mounted engine and wings shift the aircraft’s center of gravity rearwards, improving fuel efficiency, although this will also make the plane slightly less stable and more difficult to handle during takeoff and landing.

Why do aircraft have tail mounted engines?

Wings on an aircraft with rear-mounted engines can be simpler since they didn’t have to support the extraneous weight. Also, since the engines are higher up they’re less susceptible to FOD – foreign object damage – debris or rocks that can be sucked into the engine when the aircraft is taking off or landing.

Why are under wing mounted engines the most common layout for transport aircraft?

Placing engines on the wing provides beneficial wing bending relief in flight. The further the engines are away from the fuselage the greater the wing bending relief so engines buried in the wing root provide little relief.

What is end plate effect?

The endplate causes a blockage effect on the flow and an additional viscous effect, especially near the endplate. This combined effect of the endplate significantly reduces the magnitudes of the velocities under the lower surface of the wing. The largest combined effect of the endplate occurred at the lowest clearance.

What are the disadvantages of a fuselage mounted engine?

Disadvantages of fuselage-mounted engines: Worse accessibility for maintenance. Variants using a different engine cost much more to develop. Engine fires or loss of a turbomachinery blade pose a much bigger threat to the structure. No bending moment reliefor flutter dampingfor the wing.

Are wing-mounted aircraft engines possible?

Wing-mounted engines can only be found in designs which were optimized for raw speed, such as the P-38or the YF-12. Even the Me-262was initially designed with fuselage-mounted engines, hence its triangular fuselage cross section.

Where are jet engines mounted in a fighter aircraft?

Most modern jet fighter designs incorporate their engine(s) within the fuselage, while most other medium/large aircraft mount them either under the wings or on the rear fuselage. What are the advantages and disadvantages of in-fuselage jet engine placement, compared to those mounted on the fuselage or wings of an aircraft?

What are the advantages and disadvantages of under-Wing vs aft-mounted engines?

— Submitted by reader Dave, Golden, Colo. Answer: Each has advantages and disadvantages. Under-wing engines provide easier access to service but are limited in size by the height of the landing gear. Aft-mounted engines require that the horizontal stabilizer be above the engines, usually resulting in a T-tail.
