There are many theories currently out there that explain lift. The two more common theories of lift involve Bernoulli's theorem and Newtons Third law of motion.
Bernoulli's theorem states that if the velocity of a fluid increases the pressure decreases (note: air is classed and looked at as a liquid in fluid mechanics which is used to explains Bernoulli's theorem's streamlines of airflow running over the wing are forced upwards and closer together causing an increase of airspeed over the wing. This results in a decrease in pressure above the wing in relation to the air under the wing. The second law of Thermodynamics states in simple terms that areas of high pressure will go to areas of low pressure to equal out the imbalance. This results in an upwards push of air lifting the wing with it. This is the cause of more than 95% of lift on an aircraft.
The second way lift is produced by the wings has got to do with Newtons third law of Motion. The air that flows over the wing is eventually angled downwards slightly as it leaves the wing surface. This downwards force of air pushes back in the opposite direction (upwards) on the aircraft also helping with the production of lift. Additional to this (if you look closely) you will see that the wing is attached to the body of the aircraft on a slight angle. As the airflow hits the wing some of this is angled straight down and once again the force of the downwards air pushes back on the wing in an upwards direction with equal and opposite force. This final method is additionally seen when an aircraft tilts back to climb. More surface of the wing is exposed directly to the airflow causing more air to be pushed downwards increasing the overall force created by this method.
Hopefully this isn't too complicated and if you want a better explanation or links to useful resources feel free to send me a message.
It depends on the mass of the plane. The heavier the plane, the more lift it needs.
It is thrust, lift, drag and weightthat affect an aircraft's ability to fly. It is thrust that moves the aircraft forward through the air. The thrust overcomes drag and provides (with the wings) lift to overcome weight.
There is a reason birds fly and pigs do not. Birds have hollow bones and are light. The lift of the wings can support their light weight. Pigs have heavy bones and do not have the strength to either jump or lift in their appendages to support their weight. In airplanes, a heavy airplane, C130, must have more lift in the wings than a light airplane.
Lift Gravity Thrust Drag Lift is the lifting force that allows airplanes to fly, gravity is the force pulling it back down. Thrust is the force that propels an airplane forward, drag is the aerodynamic friction slowing it down. These variables are constantly interacting with eachother, when an airplane is in straight and level flight, these forces are said to be in balance.
Usually not, but it would depend on the airplane, the pilot, and what you mean by "fly".
An airplane produces enogh lift to fly with weight. Cargo planes are designed to do that.
The 4 forces that let a airplane fly are Lift, Gravity, Thrust, and Drag.
Lift! The wings on a plane create an upward lift.
Lift
Lift enables the aircraft to fly with heavy loads.
Lift created from wind under the wings
Lift and thrust is what enables an airplane to maintain flight. Lift is generated by the wings, and thrust is generated by the engine or propeller. Combined they enable the aircraft to fly. Air currents and up-drafts, on an aircraft that does not have an engine (like a glider), also help generate lift and thrust to keep such an aircraft in the air. However, gliders get into the air by being towed by an airplane, or by a sort of sling-shot.
Lift keeps an aircraft up, thrust pushes it forward.
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..
Thrust, lift, gravity, and drag
It depends on the mass of the plane. The heavier the plane, the more lift it needs.
Thrust and Lift. Gravity and drag make planes more difficult to fly.
