WebGliding fixed-wing aircraft, including various types of free-flying gliders and tethered kites, can use moving air to gain altitude. Powered fixed-wing aircraft (aeroplanes) that use an … Ground Effect is the name given to the positive influence on the lifting characteristics of the horizontal surfaces of an aircraft wing when it is close to the ground. This effect is a consequence of the distortion of the airflow below such surfaces attributable to the proximity of the ground. It applies to … See more The increase in Liftlift created by Ground Effect comes primarily from a reduction in the amount of induced draggenerated which improves the lift/drag ratio. In most circumstances, this … See more In ground effect, the angle of attack required before a wing stalls, for a given amount of lift, is reduced. The extent of this decrease in stalling angle of attack will vary according to the … See more Since the ‘lift bonus’ attributable to ground effect is primarily a consequence of a reduction in induced drag, the way in which this changes … See more A similar increase in the lift generated in ground effect, compared to free air, applies to a rotary wing when in the hover for essentially the same reasons identified for the fixed wing … See more WebThis work tackles the problem of minimizing the altitude loss of a thrustless aircraft flying towards a designated target position, and applies the algorithm on a Cessna 172 model, demonstrating both the altitude-loss optimal trajectory calculation, and determination of airstrip reachability.

"WebOct 25, 2024 · When you're in ground effect, you have smaller wingtip vortices, less downwash, and more vertical lift, all of which dramatically reduce induced drag. It all happens within one wingspan or less of the ground. So the next time you find yourself floating down the runway, go-around, and try another landing at a little slower speed. … " - Fixed wing ground effect
