FLIGHT THEORY (PART I)
The four forces
Lift: The lift force is generated by a pressure differential between the upper and lower surfaces of the wing caused by the aerodynamic reaction to the wing motion through the atmosphere. The magnitude of the pressure differential and the consequent momentum applied to the airflow is generally dependent on the speed of the aircraft, the angle of attack and the physical characteristics of the wing. Ailerons, flaps and other lift and drag changing devices are fitted to the wing f control and performance purposes.
Weight: The force due to gravity, or weight, of an aircraft on the ground , including the weight of aircraft plus passenger, baggage , cargo and mail. In order to fly the lift generated by increasing the speed of aircraft engines and angle of attack must be higher than the weight. So when take-off, the aircraft must get a suitable speed at the runway and the speed can change depend on the weight of the aircraft on each flight.
Thrust: generated by the engines, and the air resistance , caused by the friction and pressure of the airflow over the body and wings of the moving aircraft, and trying to slow it. The thrust acts forward along the flight path .
Drag: the force that exactly equals the backward force along the flight path, generated by the air resistance is called the Drag.
The shape of the cross section of the wing, with the function of producing a controllable net aerodynamic force by its motion through the atmosphere. A rounded leading edge of the wing (fonned by the aluminium tubing leading edge main spar) which directs the airflow into the upper and lower streams at all angles of attack.
In a powered aircraft the motion through the air is provided by the thrust so, in effect, the aerofoil is a device that converts thrust into lift. A rounded leading edge which directs the airflow into the upper and lower streams at all angles of attack. The aircraft wings are designed
An important principle in aerodynamics. It is this principle that says that where there is an increase in flow velocity of a gas there is a decrease in pressure for a fixed volume. The shape of an aircraft wing causes the air to flow faster over the top surface than the bott m one. this means there is a lower pressure on the top surface compared to the bottom surface and so this creates lift.
