In fluid dynamics, angle of attack (AOA, α, or $${\displaystyle \alpha }$$) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. Angle of attack is the angle between the body's … Meer weergeven The lift coefficient of a fixed-wing aircraft varies with angle of attack. Increasing angle of attack is associated with increasing lift coefficient up to the maximum lift coefficient, after which lift coefficient … Meer weergeven Some military aircraft are able to achieve controlled flight at very high angles of attack, but at the cost of massive induced drag. This provides the aircraft with great agility. A famous example is Pugachev's Cobra. Although the aircraft experiences high angles … Meer weergeven • Air data boom, measures angle of attack • Advance ratio • Aircraft principal axes • Angle of sideslip • Bernoulli's principle Meer weergeven The critical angle of attack is the angle of attack which produces the maximum lift coefficient. This is also called the "stall angle of attack". Below the critical angle of attack, as … Meer weergeven In sailing, the physical principles involved are the same as for aircraft. A sail's angle of attack is the angle between the sail's chord line … Meer weergeven WebThe rates of change of lift and drag with angle of attack (AoA) are called respectively the lift and drag coefficients C L and C D. The varying ratio of lift to drag with AoA is often plotted in terms of these coefficients. For any given value of lift, the AoA varies with speed. Graphs of C L and C D vs. speed are referred to as drag curves.
