However, airplanes can be equipped with AOA indicators that can provide a visual indication of the airplane’s proximity to the critical AOA. There are several different kinds of AOA indicators with varying methods for calculating AOA, therefore proper installation and training on the us.. 2021. 7. 30. AFH Chapter 4-9 Stalls Stalls A stall is an aerodynamic condition which occurs when smooth airflow over the airplane’s wings is disrupted, resulting in loss of lift. Specifically, a stall occurs when the AOA—the angle between the chord line of the wing and the relative wind—exceeds the wing’s critical AOA. It is possible to exceed the critical AOA at any airspeed, at any attitude, and at any power setting. For these r.. 2021. 7. 28. AFH Chpater 4-4 Angle of Attack Angle of Attack The angle of attack (AOA) is the angle at which the chord of the wing meets the relative wind. The chord is a straight line from the leading edge to the trailing edge. At low angles of attack, the airflow over the top of the wing flows smoothly and produces lift with a relatively small amount of drag. As the AOA increases, lift as well as drag increases; however, above a wing’s c.. 2021. 7. 23. 이전 1 다음 반응형
