How does aircraft drag increase with speed?
Drag increases by the square of velocity increase, for example, tripling speed increases drag by a factor of nine!
What are the purposes of the slats and flaps of an airplane's wings?
Slats and flaps increase drag and also increaselift. The increase in drag slows the aircraft down, and the increase in lift lowers the stall speed, which slows the landing speed of the aircraft.
What is the purpose of winglets?
Winglets increase an aircraft's operating efficiency by reducing induced drag at the tips of the wings
What is used to slow down an aircraft?
If the aircraft is coming into land then the hinged part of the wing called Flaps are lowered to increase the amount of Drag over the wings. If you think of drag as an air-born form of braking then Flaps down means the aircraft the aircraft slows but increases the maneuverability the pilot has over the aircraft. If the aircraft is on the ground then wheel brakes are very useful
How is aerodynamics used in airplanes?
Everything on the outside of an aircraft is designed to be low drag and strong enough to cope with flight..
What happens when thrust is greater than drag?
When thrust is greater than drag, the aircraft will accelerate and increase its speed. This will lead to a climb in altitude or a change in direction due to the increased force pushing the aircraft forward.
Do rear spoilers increase gas mileage?
Spoilers decrease gas mileage. Spoilers are designed to create down force, which creates drag. The drag will increase gas usage.
How do increce drag on an airplane?
By changing the aerodynamic properties of the fuselage or wings. If you can physically interrupt the flow of air across the body of the aircraft and make it less aerodynamic than you are able to create and increase the amount of drag in flight. The 2 most common ways to increase drag in a modern aircraft is to arm the spoilers (speed brakes) or lower landing gear.
What cause thrust to increase or decrease?
Thrust can increase when engine power is increased or when the angle of attack of the aircraft is increased. Thrust can decrease when engine power is reduced or when drag on the aircraft increases due to factors like airspeed or weight.
What effect does resistance have on the acceleration of aircraft?
Resistance, or drag, acts opposite to the direction of motion and reduces the acceleration of aircraft. High resistance can slow down an aircraft and make it harder to increase speed or maintain acceleration. Pilots account for resistance when planning maneuvers and adjusting engine power to overcome drag.
What does drag do for an aircraft?
Drag slows down aircraft, which is why designers of aircraft that are supposed to be fast pointy and waisted, because a pointy shape has less drag, and waisted because of the area rule, which also helps an aircraft to go faster.
What is drag in an aircraft?
In aircraft aerodynamics, drag is the force that opposes forward motion, caused by air resistance as the aircraft is pushed forward by it's engines.
