Introduction to Flight Part 1 of 4This course is designed to help students learn andunderstand the forces that enable an airplane to fly.According to the National Aeronautics and SpaceAdministration (2010), the four forces that affect howan airplane flies are; lift, drag, thrust, and weight.Part 1 introduces the students to the first force; lift.
Course Objectives•Given several examples of both effective and non-effectivepaper airplane models, the students will be able to accuratelywhy each example is or is not an effective model for flight with95% accuracy.•Given a standard paper airplane, the students will be able toexplain the forces of lift, drag, thrust, and weight and accuratelyexplain how those forces affect an airplanes flight with 95%accuracy.•Given a standard sheet of 8” X 11” paper, the students will beable to fold an effective paper airplane that can withstand flightfor a minimum of ten seconds from the second story balcony ofthe Avionics Building.
Lift •Lift is the force that directly counters the weight of an airplane and holds the airplane in the air. •Most of an airplane’s lift is generated by the wings. •Lift is produced by the motion of the airplane through the air.
Lift•Lift occurs when a moving flow of gas is turned by a solid object.•The flow is turned in one direction, and the lift is generated inthe opposite direction.•Because air is a gas and the molecules are free to move about.•For an airplane’s wing, both the upper and lower surfacescontribute to the flow turning.
Lift•You can control lift by changing theangle of the airplanes wing relative tothe wind or by increasing ordecreasing airspeed.•You can also change the shape of thewing by lowering the flaps whichextend the area of the wing.•Anytime you do something to changelift, drag is affected. If you increase lift,drag increases. Drag is a by-product oflift.
