What produces the most lift at low-speed?

A: The straight wing is found on a lot of low-speed airplanes. This kind of wing extends from the body of the airplane at right angles. These wings provide good lift at low speeds, and they are structurally efficient, but are not suited to high speeds.

How do planes fly Bernoulli?

Bernoulli’s principle helps explain that an aircraft can achieve lift because of the shape of its wings. They are shaped so that that air flows faster over the top of the wing and slower underneath. The high air pressure underneath the wings will therefore push the aircraft up through the lower air pressure.

How does thrust help an airplane fly?

Thrust is the force which moves an aircraft through the air. Thrust is used to overcome the drag of an airplane, and to overcome the weight of a rocket. The engine does work on the gas and accelerates the gas to the rear of the engine; the thrust is generated in the opposite direction from the accelerated gas.

What are wings used for?

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.

What are trapezoidal wings used for?

A trapezoidal wing is a straight-edged and tapered wing planform. It may have any aspect ratio and may or may not be swept. The thin, unswept, short-span, low-aspect-ratio trapezoidal configuration offers some advantages for high-speed flight and has been used on a small number of aircraft types.

What are the advantages of trapezoidal airfoils?

Trapezoidal = excellent lift characteristics (as long as you don’t have to fly fast), cheap to manufacture, need to keep span short and airfoil thickness thin to go fast (e.g. F-104) Nose shape for the space shuttle was a trade of material (inconel, carbon/carbon, ceramic), weight, cost, durability.

Are tapered wings structurally and aerodynamically efficient?

Tapered wing narrows towards the tip. This indeed is structurally and aerodynamically efficient. Aerodynamicists wanted a trapezoidal wing because it provides more aspect ratio since it is good for aerodynamics. It is also probably the best balanced wings providing low aerodynamic drag at high speeds.

How do you increase the sweep of a swept trapezoidal wing?

In a swept trapezoidal wing, the line of maximum chord is swept at an angle, usually forward. This increases the sweep of the leading edge and decreases the sweep of the trailing edge, and in the extreme case both edges sweep backwards by different amounts. The transition form, where the trailing edge is straight,…
