Why are jet engines more efficient at high altitude? Jet engines work more efficiently at high altitude because the air is cooler. … Hence, the larger the expansion of the air when heated, the faster the aircraft moves because it is the expansion of air that drives the turbines of the jet engine which generates more power for lesser fuel burn.
Are planes more fuel efficient at higher altitudes? Aircraft burn less fuel for a given volume of air at higher altitudes because there’s less oxygen for it to burn. So, for a given air intake you have to lean the mixture back as you gain altitude. Aircraft fly faster at higher altitudes because lower air density means there’s less air drag.
At what altitude do jet engines stop working? Fanjet engines stop working at about 50,000 ft. Turbojet engines such as the Olympus in Concorde can reach 60,000ft. The SR71 flew to over 70,000ft but that was a hybrid ram jet and was operating at ‘coffin corner’ where even a small change in operation could cause flame out.
Which engine is best for flying at high altitudes? One of the advantages of the jet engine over the piston engine is the jet engine’s capability of producing much greater amounts of thrust horsepower at the high altitudes and high speeds. In fact, turbojet engine efficiency increases with altitude and speed.
