Aerodynamic Design of AeroplaneWhat is an aero plane?

It is a vehicle which runs at very high speed in air and during flight its weight becomes less than air.

Some History:

Write here the sentences which you have typed already by yourself in laptop.

Design features of an Aero Plane:

Lift: Lift is an artificial force manipulated by pilot; it is generated through the wings, acts perpendicular to the relative wind and wingspan. The theoretical concept that summarizes the direction and force of lift is the centre of pressure. Lift opposes weight—during level cruise, lift equals weight; during climb, lift is greater than weight; and during descent, weight is greater that lift.

Main Parts and Aero Plane:

Main parts of an aero plane are mentioned in

1) Fuselage…Main body of the airplane which holds all the other parts of it properly such as wings, tail, engine and crew or traveler sitting area. For travelling purpose, the body is kept so long and wide to fulfill the requirements. When a fighter jet is designed, only engine is needed to to put in the body with only two seats for fighter pilots. Center of gavity of plane is in the center of the body and the weight acts downward by this.

2) Wings: They are used to generate lift.

3) Slats: Slats play very important role in lifting the air plane during flight. Slats are actually the narrow edges of wings from which the having very high velocity air pass through. From top, Slat is made convex curved and its bottom is flat mostly. Its reason is to give maximum lift by air pressure from bottom of wing. From upper curved surface, air slightly flows without friction. Slats can be separated and attached in front of the wings.

4) Spoiler: Spoilers are rectangular plates hinged in center of the wings to reduce the lift of aeroplane.

5) Aileron: Ailerons are the back ends of wings from outside of the air flaps. These are used to move in sidewise direction.

6) Flaps: Flaps are also rectangular parts which are hinged with wings and used for take off and landing. They increase or decrease the lift.

7) Horizontal Stabilizer: The horizontal stabilizer is a rear wing attached on an aircraft. It is used to balance the aircraft when in motion.

(8) Vertical Stabilizer: The fixed vertical surface of an aircraft at its tail, to which the rudder is hinged.

(9) Rudder: It is used for left and right movement of airplane.

(10) Elevator: These are flight control surfaces, usually at the rear of an aircraft to move the plane upward and downward.

(11) Turbine Engine: In an aircraft gas engine is operated with high velocity air. It is assembled at the bottom of the wings. Usually two gas engines with two wings are used.

(12) Cockpit: It is the font of fuselage. It is made smooth and taper to minimize frictional effect.
