How is an airfoil shaped?
Each aircraft has a different shaped airfoil. The purpose of the airfoil shape is to reduce drag over a range of speeds which the aircraft wing operates at while providing the least possible drag at the cruising speed (regular flight speed) in order to ensure good performance.
What creates lift?
An aircraft in flight experiences an upward lift force, as well as the thrust of the engine, the force of its own weight, and a drag force. The lift force arises because the speed at which the displaced air moves over the top of the airfoil (and over the top of the attached boundary layer) is greater than the speed at which it moves over the bottom and because the pressure acting on the airfoil from below is therefore greater than the pressure from above,This is how planes get lift.
What is an airfoil?
an object shaped to produce lift by the bernoulli principle when moving in a fluid
Why drag increases as lift increase - for helis?
The production of lift creates induced drag. To create more lift, more airspeed is needed, and with airspeed, comes drag.
Did the Wright brothers invention work and why?
Their aircraft? Yep. It was a biplane, and it produced lift by moving air over an airfoil. The effect of an airfoil is described in part by the Bernoulli Principle.
Who designed the first airfoil?
In 1939, Eastman Jacobs at the NACA in Langley, designed and tested the first laminar flow airfoil sections. These shapes had extremely low drag and the section shown here achieved a lift to drag ratio of about 300.
How do you control drag from increasing on helicopter?
Drag cannot be eliminated because drag always acts parallel to the relative wind. We can control by purchasing or using the right airfoil on the aircraft. An airfoil with smooth surface produces more lift than one with a rough surface. A rough surface creates turbulence, which reduced lft and increases drag.
How does an airoplane fly?
it has a shape on its wing called airfoil search it up it combined forces of thrust weight drag and lift must be equal.
Will any shape work an airfoil?
Each aircraft has a different shaped airfoil. The purpose of the airfoil shape is to reduce drag over a range of speeds which the aircraft wing operates at while providing the least possible drag at the cruising speed (regular flight speed) in order to ensure good performance.
What is the difference between airfoil profile and airfoil section?
The difference between airfoil and airfoil section is that airfoil is a structure with curved surfaces designed to give the most favorable ratio of lift to drag in a flight, it is used as the basic form of wings, fins, and tailplanes of most aircraft. An airfoil section is the cross- sectional shape or profile of an airfoil. I studied that in sixth grade for a model plane that I did a report on. Researching into things that aren't required can help put you farther into life's riches. Hope I helped.
What has the author Edwin J Saltzman written?
Edwin J. Saltzman has written: 'In-flight lift-drag characteristics for a forward-swept wing aircraft (and comparisions with contemporary aircraft)' -- subject(s): X-29 aircraft, Wave drag, Lift, Airfoil profiles, Swept forward wings, Drag, Transonic speed
Why an airfoil is important for flight?
airfoil is important beacause it boils
What shape is most conducive to optimizing lift?
airfoil
What is subsonic airfoil?
which airfoil must produce the lift with less than one mach number . that is called sub sonic airfoil...... Another answer would be : an airfoil designed to perform below the speed of sound.
What does Hydrofoil mean?
1. an airfoil-shapped "wing" designed to operate in the water; used to lift boats and ships out of the water at high speed to reduce drag 2. a ship equipped with hydrofoils
How is an airfoil shaped?

How does airfoil generates?
The air shear going under the wing when flaps are down pushes the plane up off the ground. The reason why planes have wings up is to create low drag and high lift.
