It´s often my daily/nightly job hovering outside ground effect - sometimes from refuelstop to refuelstop - but thats another story. My boss gives me an appropiate helicopter and normaly I avoid hovering with tailwind.
Web10 de abr. de 2024 · “Ground effect” is the effect of a “cushion” of air, which forms close to the ground under a hovering helicopter, and helps to hold it up. This increases aerodynamic performance, and the result is that the helicopter can hover with less power. But it only works when the helicopter is around 1 – 1.5 rotor lengths above the ground. … Web28 de jun. de 2024 · Abstract.
