Lift can be increased by curving the wing downward. Most aircraft have 'flaps' at the rear inner edge of the wing to achieve this. Some aircraft even have 'slats' at the front of the wing to increase lift even more. - If you Google 'aircraft slats', you will see a great picture of slats and flaps on an Airbus A310

Can an aircraft overcome lift without wings or propellers?
No, that is not possible except with rotors. (which I would include among propellers)
Why are the wings of some planes bent up at the tips?
These are called winglets. They reduce drag therefore increase lift.
What is the difference between the flight of a plane and a helicopter?
Both use the pressure difference caused by air moving over the wings at different speeds to generate lift; a plane by moving those wings in the direction of travel, a helicopter by spinning the "wings" around at high speed. This requies that the plane be in constant forward motion in order for the wings to make lift. Thus airplanes must roll along the runaway to take-off. A helicopter cant take off at zero forward speed and hover at zero forward speed. The helicopter can land and take off vertically. Thus, they are good for landing in unimproved spots such as done by air ambulances.
What was the three major differences between the first generation and the final generation design of the Gossamer Condor?
The final generation Gossamer Condor had swept back wings, the wings undersides were covered with mylar, and there was an enclosed space for the pilot. All of these changes increased the airplane's performance.
How fast does a propeller have to spin to lift a man off the ground?
That's a difficult question to answer. First, in the sense that a propeller is really an airfoil, it does, in fact, generate lift. However, the concept of lift with respect to aircraft, generally refers to the vertical lifting force, and this is produced by the airfoils (wings) and not the propeller. The propeller produces forward thrust which, when sufficient, generates the speed necessary for the wings to produce lift. So, back to the question: A propeller needs to turn fast enough to produce enough forward speed for the airfoils to produce sufficient lift for the aircraft to rise. The RPM necessary to do this depends on the size and number of blades, the power of the engine, the weight of the aircraft, and a number of other factors such as airport elevation, etc. Sorry this doesn't exactly answer the question, but hopefully it will help you craft a more specific question that can be answered more accurately.
What makes airplane fly?
Lift! The wings on a plane create an upward lift.
What is lift augmentation?
A device to aid lift, such as Slats and Flaps on the wings.
Sould there be big wings or small wings on a plane?
With big wings you can get lift with less trust Small wings you would need a lot of trust to keep the lift. How about a happy medium
Why are wings used on racecars if they produce lift on planes?
If that wing is turned upside down, it increases drag instead of lift. Race cars use this increased downward force to give them more traction at higher speeds.
Whats the relationship between speed and lift?
Lift is proportional to the density of the air and approximately proportional to the square of the flow speed. Lift also depends on the size of the wing, being generally proportional to the wing's area projected in the lift direction.
What is the primary source of lift?
the wings
Which aeronautical term refers to an airplane with three similar-sized wings or pairs of wings?
A triplane is an aeronautical term that refers to an airplane with three similar-sized wings or pairs of wings. These wings are stacked one above the other to provide increased lift and maneuverability. Triplanes were popular during World War I for their agility and climb rate.
How do ladybugs createe lift and thrust?
lady bugs create lift and thrust when they flap their wings. They creat lift by flapping their wings and then they steer to creat thrust. I hope this helps!!!!!!!!!!!!!!!!!!!
Why aeroplane designed with wings?
An airplane has wings to generate the lift required for flight.
How does a chicken straighten out its wing?
It has bones all the way down its wings. That is how they open/lift they're wings. Just like how we lift our arms.
What is lift augmentation devices?
A device to aid lift, such as Slats and Flaps on the wings.
Why the wings of the airplane is design that way?
Because the whole point is for the wings to provide lift. Many designers spent hours watching how bird wings were shaped and how they moved to provide lift or propulsion.
