Yes, otherwise airplanes would be unable to go upwards into the sky.

Yes, a wing can (given sufficient forward speed and angle of attack) generate lift greater than the weight of the aircraft. As with any "unbalanced" force, this will result in an acceleration of the airplane in the direction of the lift, according to Newton's Second law. $$\mathbf F=m~\mathbf a$$ Please note, the entities in bold face are vector quantities....

Furthermore to @Zeiss' answer, whenever an aircraft is steady-state banked, the lift will be greater than its weight. However, its speed will be constant; instead, the acceleration is centripetal and results in a circular turn. Edit, clarification on pull up maneuver: When an aircraft is pitched up via pitch control, and after the short-period mode settles ...

I'm haven't flown them but am very familiar with them and the reflex wing controversy because I was interested in getting into the sport (I normally fly power and gliders). A reflex wing when in "reflex mode" offloads the aft part of the wing and shifts the pressure distribution forward. Effectively, the rear part of the wing is being allowed to "trail", ...

The MH 24 airfoil has been popular for years at international radio-control pylon racing events. Just ensure that your chord and airspeed give you a Reynolds number exceeding 400,000. Because airfoils designed for high speed often work poorly at low speed, consider equipping your model with flaps, to make landing easier. At lower Reynolds numbers, the ...

The outer kink on A340-600 wing is located just outboard of the outboard engine, note trailing edge kink in planform drawing.

If the airfoil profile does not change along the span, then we can expect the entire wing to enter a stall condition at the same time. This means the stall break will be sudden and sharp. If instead we transition between several different airfoil profiles along the span of the wing, we can get different portions of the wing to stall at different airspeeds/...

A kite is a simple aircraft, generating lift. The vertical component of the pull you feel on the string is any resultant lift greater than the weight of the aircraft, the horizontal component being the drag. In a non-tethered aircraft, excess lift causes the aircraft to "rise", or more precisely, causes the flight path to curve upwards.

"What would happen if the thickness...are same throughout the wing". This is known as a "Hershey bar" wing, and is an excellent general purpose, easy to build wing for models and full scale aviation aircraft alike. Aircraft designers add twist or "washout" to wings to prevent the entire wing from stalling at once. Washout lowers the angle of attack of the ...
