What is the moment of the playground?
Aircraft moving air develops a lift or force up that overcomes the weight, air moving over the wings. One way the aircraft moves is when the nose or front of the aircraft moves up or down, often referred to as a playground. Moment of the pitching is to measure up and down for different air angles over the wings, known as the angle of attack.
Most aircraft with a solid wing have two or four wings in about half of the fuselage, the main body of the plane. The wings have moving handles that move the wings up or down, known as rolling the plane. In the tail or rear of the fuselage is a horizontal stabilizer with a moving panel of the elevator to control the climb up or down. The horizontal stabilizer often looks like a smaller wing on each side of the tail in a flat or horizontal position.
vertical stabilizer with movable rudder panel is placed vertically up from a horizontal stabilizer to move nose back and forth, which is a controllerThe element. All moving surfaces are attached to a pilot control wheel or wand and to the stem pedals controlled by the pilot's legs. The pilot can ban or roll, turn left and right and turn or move the nose back and back with the controls.
If the aircraft moves up or down from movement in the elevator, power supply or weather turbulence, the attack angle changes for air flow through the wings and the horizontal stabilizer. The horizontal stabilizer is designed as a wing upside down and creates a playground up to force the nose down. Other parts of the aircraft try to push the nose up due to aerodynamic forces, which are the effects of air movement through different surfaces.
Forces created by a horizontal stabilizer are often referred to as torque, a force measurement that is a distance from the point of rotation. The point of rotation on Aircraft is usually a center of gravity, which is an imaginary point where wouldThe aircraft could be lifted and in perfect balance. Weight, luggage and fuel passengers change the center of gravity or CG and the calculations are carried out by pilots to determine that their aircraft is flying to an acceptable extent of CG.
The moment of pitching formed by a horizontal stabilizer occurs from the wing much smaller than the main wings. This is possible to calculate the torque. For the required amount of force, the wing can be smaller because it is further from the center of gravity. Almost all aircraft have a long tail with horizontal and vertical stabilizers at the other end for this reason.
When the angle of the attack becomes too large, the air will no longer flow through the upper and lower part of the wing. There is turbulence, the air no longer flows along the wing and the wing does not create an elevator. This is known as an aerodynamic stand and the aircraft can no longer maintain Leflice size CG series is carefully designed and tested by manufacturers, so the nose of the aircraft drops when stopping. This allows the aircraft to get speed and restore streamAir through the wings and tail and is caused by the designed torque of the aircraft.
If the pilot accidentally adds too much weight to the back before the flight, the aircraft does not have to recover from the booth. The horizontal stabilizer cannot develop sufficient to overcome overweight and reduce the nose. This is known as AFT or rear CG and is very dangerous if it is not repaired by the pilot.
Moment of pitching can also change from the aerodynamic effects that occur near the Earth, called ground effect. The ground effect is caused by changes in the way the air moves through and below the wings and affects the moment of lifting and pitching. This can cause the nose to spread just before landing and contribute to accidents if the pilot does not understand it.
