Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of www.- aircraft generally cruise most efficiently at about Mach.
For the sake of clarity, some definitions: reaction engine: includes both rockets and www.- engine pushes some mass in one direction and by reaction it achieves thrust in the opposite one.. jet (engine): is used to refer to airbreathing engines. The aircraft carries the fuel, but not the oxidizer; that is taken from the surrounding atmosphere. Jan 27,  · This is why real life rockets and planes are streamlined: They are shaped in a manner that makes it easy to part the air in front and lead it around the rocket.
