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.

How wing is attached to fuselage?

The wings are attached to the main fuselage body using a lug. The bending moment and shear loads from wing to the fuselage structure is transferred through the lug structure. The attachment is done by series of pinned lug between wing side of wing box and fuselage.

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.

What are the advantages of wing mounting the engines?

$\\begingroup$An advantage of wing mounting the engines is that it frees up fuselage space for cargo, be it boxed or self-loading.$\\endgroup$ – FreeMan Apr 3 ’19 at 18:46

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

One advantage of the aft-mounted engines is that they do not create as much asymmetric thrust as under-mounted engines when one engine fails, because they are much closer to the centerline of the airplane. Under-wing mounted engines produce a significant yaw when an engine fails, while aft-mounted engines produce less.

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?
