why jet engines are attached to the wings of the airplane ,not other part?
Why Jet Engines are Attached to Airplane Wings
Click For Summary
Jet engines are typically attached to airplane wings for reasons related to aerodynamics, weight distribution, and maintenance efficiency. While some aircraft, like military jets, have engines mounted in different locations, wing-mounted engines generally enhance stability and reduce drag. The placement also allows for easier access during maintenance. The design decision is influenced by the aircraft's intended use and performance requirements. Understanding these factors is crucial for grasping modern aircraft design principles.

They are not always placed on the wings. Where is the engine in an F-16 jet?

thank you so so much berkeman,it was Great.
A rule of thumb of aircraft engineers is every 10% increase in the power level engines are run at corresponds to a 50% decrease in engine lifetime. This is a general phenomenon of turbomachinery. Then it is likely it also holds for rocket turbopumps.
Then quite key is the rule also holds in reverse, every decrease in power level by 10% can result in doubling the lifetime of the engine. Then by running the engine at 0.9^5 = 0.60 power level can result in 2^5 = 32 times longer lifetime. For...
