How does the wing shape affect flight?
Airplanes’ wings are curved on top and flatter on the bottom. That shape makes air flow over the top faster than under the bottom. As a result, less air pressure is on top of the wing. This lower pressure makes the wing, and the airplane it’s attached to, move up.
Can fighter jets go straight up?
The F/A – 18 has a thrust to weight ratio which is greater than 1-to-1. This means that the engines produce more thrust than the weight of the plane in certain situations. This means that it can keep flying up vertically, as long as the air supply to the engines does not reduce significantly.
What gives an airplane a forward force?
“As an airplane’s propellers spin, they give the airplane a forward force (thrust). As an airplane moves forward, the shape of its wing creates lower pressure above the wing than below, yielding a net upward force known as lift.”
How do the wings of an airplane generate lift?
The wings generate most of the lift to hold the plane in the air. To generate lift, the airplane must be pushed through the air. The air resists the motion in the form of aerodynamic drag. Modern airliners use winglets on the tips of the wings to reduce drag. The turbine engines , which are located beneath the wings,…
Why do aircraft fold their wings before take off?
To save space aboard the deck of U.S. flattops, aircraft built for carrier operations can fold their wings making room for more planes. Obviously wings must be extended tbefore catapult launch. But what happens if the wings aren’t unfolded before take off?
Why does a plane fly with a lot of drag?
That shock wave generates lots of drag. The air flowing over the wing crosses a massive pressure boundary, which sucks energy out of the airflow – causing drag. Plus, the air can lose so much energy that it separates from the wing, causing more drag.
What is the difference between a swept wing and straight wing?
On a straight wing airplane, all of the airflow over the wing travels parallel to the aircraft’s chord line. But, on a swept wing, only some of the air flows parallel to the chord line. The other part flows perpendicular to the chord – this is called spanwise flow. Only the component of airflow flowing parallel to the chord line accelerates.
