Ground effect on takeoff
WebDec 23, 2024 · For takeoffs, you start out in ground effect, where the increased lift and decreased drag help you to build airspeed. Your aircraft may become airborne at lower than rated takeoff speed. As you begin your ascent and climb out of ground effect, more power must be used to maintain your rate of ascent.

A helicopter takeoff profile is governed by having enough margin to autorotate to a safe landing in event of engine failure, not by more efficient flight due to ground effect. Margin consists of both forward speed and …
WebAug 25, 2024 · At take-off speed. so, the thrust at take off is. TTO = Pav/VTO = 3600 hp / 168 fps = (1980000 ft-lb/sec) / 168 fps = 11786 lb. Our thrust versus velocity relationship is. T = T0 -aV2. Substituting the takeoff speed and thrust and the static thrust we can find the value for a. 11786 lb = 13000 lb – a (168 fps)2.
