The students will be able to explain how air power can help airplanes fly. The students will construct a working model of an air engine.
Aircraft powered by jet, piston, or rocket engines are capable of sustained flight.
Remaining aloft longer means the aircraft offers greater utility and convenience to users. The aircraft engine provides a constant source of thrust to give the airplane forward movement. The straw represents the fuselage and the balloon represents the aircraft engine. Once the balloon is filled with air, there is a difference in air pressure between the outside and the inside of the balloon. The inside of the balloon has higher pressure than the outside of the balloon.
