ROTOR MOTOR Objectives The students will: Construct a rotary wing model. Define a mathematical relationship using a model. Standards and Skills Science Science as Inquiry Physical Science Position and Motion of Objects Science and Technology Science Process Skills Observing Making Models Controlling Variables Mathematics Problem Solving Estimation Measurement Graphing Background Air must move across the surface of a wing to produce lift. To fly, birds and insects use a flapping motion to move the air over and around the wing surface. The wings of airplanes are attached to the fuselage in a fixed position. Lift is generated by moving the entire wing and body through the air. Helicopters are rotary wing aircraft; they rotate the wing surface through the air to produce lift. 72 Aeronautics: An Educator’s Guide with Activities in Science, Mathematics, and Technology Education EG-1998-09-105-HQ
lift lift fixed wings rotating wings direction of blade through air lift faster airflow/lower pressure slower airflow/higher pressure cross section of aircraft wing, or a rotor blade rotor blades Lift is produced by the pressure differences caused by the shape of rotating blades; this is the same way lift is produced by aircraft wings. The rapidly moving air over the top of the blade creates low pressure; the air beneath the blade is moving slower, so it creates higher pressure (see "Paper Bag Mask" pages 26-27, Bernoulli's principle, for more information). High pressure under the rotor blades creates lift which causes the aircraft to rise. Since the paper models have no motor, they only have one source of lift. As the paper models fall they will spin, imitating the rotation of the rotor blades of a helicopter. Because there is no thrust to produce upward movement, the helicopter will not fly upward, but the spin will reduce the rate of fall by producing lift, resisting the force of gravity. paper model NASA builds and tests experimental helicopters and tiltrotor airplanes in an effort to achieve lower noise levels and greater fuel efficiency. Models are tested in NASA's wind tunnels at Langley, Lewis, and Ames Research Centers.
