aircraft angle of attack(common designation- alpha) - The angle between the direction of velocity of the incident flow on the body (liquid or gas) and the characteristic longitudinal direction selected on the body, such as the aircraft it will wing chord, - construction longitudinal axis of the projectile or missile y - axis of symmetry.
When considering it necessary to distinguish the aircraft wing angle of attack (as defined above) and slip angle (located in the plane normal to the angle of attack).
The angle of attack (the aircraft carrier surface) is one of the key features in the operation of the aircraft, and the solution of problems of flight dynamics. The angle of attack affects the lift of the wing, with it being in direct proportion.
aircraft angle of attack
However, increasing the angle of attack and also leads to increased inductive resistance (intrinsic resistance of the wing airfoil or airplane).
The dependence of the lift coefficient on the angle of attack
In solving the problems of flight dynamics of the angle of attack is defined as the angle between the positive direction of the x-axis and the velocity vector of the flight.
An interesting fact can serve as a fact that there are aircraft capable of changing the angle of attack (by changing the installation angle of the wing) in flight or on the ground. An example is the US carrier-based aircraft A-8.
