What is the purpose of the flaps on a plane?
Wing flaps change the shape of the airplane wing. They divert the air around the wing as necessary. The setting of the flap determines whether they are used to increase lift (as on takeoff) or increase drag (used on landing.)
What is the physics behind flying an airplane?
Forces acting upon an aircraft Drag – acting opposite to the relative motion of the aircraft, generated by the air resistance. Thrust force makes the airplane move forward. As the airplane moves forward, the relatively flowing air over the wings will produce a lift force on the wings.
How does physics affect the performance of an airplane?
These force more air downward and increase the pressure difference on the wing. Physics describes the performance of propellers and helicopter rotors in precisely the same manner. The force of gravity on the Earth is measured to be 9.8 Newtons/kg. An aircraft must overcome this force to get airborne.
How does the angle of attack work in an airplane?
The angle of attack (Newton) and the change in pressure (Bernoulli) both act to direct the aircraft in the desired direction. Various types of flaps are used to increase lift for landings and takeoffs. These force more air downward and increase the pressure difference on the wing.
How is the force of gravity measured on an airplane?
Physics describes the performance of propellers and helicopter rotors in precisely the same manner. The force of gravity on the Earth is measured to be 9.8 Newtons/kg. An aircraft must overcome this force to get airborne. To be of any use it must also lift passengers, fuel and cargo.
How are drag and thrust related to flight?
Flapping the wings quickly or moving quickly generates lift well, as does having a large wing area. Thrust is also a vital force for flyers; without it, the drag forces would slow the animal down enough to reduce lift forces (i.e., down we go!). Having large flight muscles is a good way to produce thrust.
