How can a plane create more lift?
To produce extra lift at takeoff, planes have flaps on their wings they can extend to push more air down. Lift and drag vary with the square of your speed, so if a plane goes twice as fast, relative to the oncoming air, its wings produce four times as much lift (and drag).
How does the design of the airplane affect the lift?
How does the design of the airplane affect the lift? Lift is created by the shape of the wing, which makes the air pressure above the plane’s wing less than the pressure below. This causes the plane to lift forward. When the lift is greater than gravity, the plane goes up.
What type of stress resists a crushing force?
Compression is the stress that resists a crushing force. [Figure 1B] The compressive strength of a material is also measured in psi. Compression is the stress that tends to shorten or squeeze aircraft parts.
What kind of aircraft has a lifting body?
A lifting body is an aircraft that relies for lift on the shape of its fuselage, not on protruding wings. Many early lifting bodies were triangular as viewed from above and “tubby” as viewed from the side.
Can a jet plane separate from a lifting body?
The crew could, if required, take advantage of the lifting body’s crossrange capability to steer far from their orbital path. The jet plane separates from the lifting body pod.
How are planes designed to reduce skin friction?
Minimizing the wetted surface area is aimed at reducing skin friction and has led to the design of planes that are basically one single body with wings. Splitting up a larger body into a number of smaller bodies, with the same overall volume and hence cargo and passenger space, increases the surface area and hence skin friction.
What makes a good model for an airplane?
A good model should give you a lot of bang for the buck. The means being able to predict relevant quantities about the real world while making a minimum of assumptions. As a plane moves, it carves out a tube of air. This air was stationary, minding its own business, until the airplane rammed into it.
