Ok so im wondering what restricts a plane or helicopter or in other words causes it to lose energy (speed)

EXAMPLE: gravity, and airflow

Layman: What keeps a flying vehicle from getting like 1000 mpg?

If you were trying to make a flying vehicle from scratch lets say?

wings are important to generate lift, however they also do a pretty darn good job at generating drag.
Cars have transmissions so you can keep changing gears to keep your revs low and use less gas. But in a plane the friction increases w/ speed so you keep needing more and more power to stay at a faster speed so you could never hook up a transmission. Moving to a larger gear would create a loss in power that would slow you down...so a plane's engine must keep speeding up and speeding up using more and more fuel.

The major cause of loss of power in fly vehicles are air resistance, heat carried away by the exhaust, gravitation force, friction between the internal parts of an engine or turbines.

Most engines loose power the higher that u go the less ox. u have the less fuel that will burn giving the efficient power. Turbines are affected less but when u burn fuel u got to have xo.
