ground effect

ground effect
ground effect
A condition of improved performance (lift) due to the interference of the surface with the airflow pattern of the rotor system when a helicopter or other VTOL aircraft is operating near the ground.
Note.— Rotor efficiency is increased by ground effect to a height of about one rotor diameter for most helicopters.

Official definition added to PANS-RAC by Amdt 5 (10/11/1994).
эффект земли; влияние земли
Улучшение лётно-технических характеристик (подъёмной силы) за счёт взаимодействия поверхности земли с воздушным потоком, создаваемым системой несущих винтов, когда вертолёт или другое воздушное судно СВВП выполняет полёт вблизи земли.
Примечание. У большинства вертолётов эффективность несущих винтов повышается под воздействием эффекта земли до высоты, соответствующей примерно одному диаметру несущего винта.
