Why do jet engine airplanes fly faster than propeller airplanes?
Jet engines are faster due to the way they generate thrust. They produce thrust by increasing the pressure inside the engine with a combustion reaction. The increased pressure in the engine exerts more force in the forward direction. Propeller airplanes generate thrust using the difference in air pressure created by the rotating propeller blades. The shape of the propeller blades are like a twisted wing. Jet engines just have the ability to generate a lot more power to thrust the aircraft forward.
