Flying Models – Aero modelling
The flying models are those models which can be flown using various techniques. To proceed further you are required to know few basic facts about the flying. Sometime we may have this question in mind that why and how the aircrafts are able to fly in the air. To understand this you must know certain facts:
Every flying body has the four forces acting on it and they are – lift, drag, weight and thrust. While the lift and thrust act as the positive forces, the weight and drag act as the negative force on the flying body. On elaborating the each term we arrive to the conclusion that weight is due to the mass of the body and other accessories of the aircraft, it can be reduced or increased as per requirement a little bit. Weight pulls down the aircraft towards the earth. Drag is the force which restricts the forward movement of the aircraft and is generated due to the shape of the aircraft and reaction blockage generated by the airflow for the movement of the aircraft. To counter this blockade the aircrafts are designed in such a way that blunt edges or the corners are avoided while designing the aircraft.
Next in line comes the lift factor, this force is mainly responsible for the flying of the aircraft. This is obtained mainly from the main wings of the aircraft. To obtain the lift the wings are designed in a special way. The mechanical aspect of the lift is explained further for your benefit. The wings are shaped in a special way known as the aerofoil and passing of the air through the surfaces of this shape is the cause of the production of the lift. The greater the speed of the aircraft, amount of the lift produced would be more, one more thing is to be remembered in this regard and that is greater the amount of the weight greater the amount of the lift is required. Next is the thrust, it is provided by the engine of the aircraft. Greater the amount of the thrust more efficiently the aircraft would be to counter the drag and provide greater lift.
The Flying model can be divided in the following categories:
