the difference between an helicopter creating lift and an airplane creating lift is simple. an airplane creates lift by moving forward and its wing that has an aerofoil shaped will create lift. this gives the lift for the airplane and to fly. for helicopters, instead of the aerofoil is fix like an airplane, the aerofoil wing is rotating and create lift. that is why the helicopter does not need to move forward to gain momentum to create lift. by rotating the aerofoil (the blade) the helicopter can creates enough lift to lift up the helicopter.and that's how it fly..
The wings and horizontal tail surfaces create lift.
Lift! The wings on a plane create an upward lift.
While airplanes need to be in motion with enough momentum to create enough airspeed for lift off, helicopters can lift off vertically without any momentum of the aircraft. Both aircrafts need a rotary wing. Helicopter wings are rotary and have the capabilities to change the angle or pitch in order to create more or less lift. Airplanes have rotary and fixed wings.
Snowmobiles only need a lift if they need to be worked on. If you need to put a new engine into your snowmobile you would need to have a lift to be able to get under it and work. If you need to check your traction same goes for needing a lift to look under it.
Thrust and lift are required to make a plane fly. A plane can use just lift if it is in the air already. The engines create thrust (if the aircraft has engines), and the wings create lift. Helicopters make lift by pushing air down, though.
Aircraft using fixed wings need to maintain a certain airspeed over the wing to create lift. Aircraft like the AV-8 Harrier and the new F-35 Lightning II point exhaust from the engine downward to create lift at low airspeeds.
i guess they are just made that way
To create lift and flight direction.
Because the plane has to overcome the force of gravity and it has wings to create lift to make the aircraft fly.
The production of lift creates induced drag. To create more lift, more airspeed is needed, and with airspeed, comes drag.
By spinning its rotors to create downward thrust.
