WebOne can expect optimum fuel efficiency from them at altitudes below 25,000 feet. Turboprops can further reach a ceiling altitude of 30,000 feet. Turboprop engines are built to generate thrust primarily through the rotation of the propellers. These propellers work more efficiently at lower altitudes where the air is denser. WebMay 13, 2024 · Thrust is the force which moves an aircraft through the air. Thrust is generated by the propulsion system of the airplane . How is thrust generated? Thrust is a mechanical force which is generated through the reaction of accelerating a mass of gas, as explained by Newton's third law of motion.
