Quiz: Understanding Aircraft Performance

Flight Training Central

What is ground effect? Ground effect is most likely to result in which problem? Floating caused by the phenomenon of ground effect will be most realized during an approach to land when at less than the length of the wingspan above the surface. Becoming airborne before reaching recommended takeoff speed.

No Spruce Goose: US Takes Second Shot At 'Ekranoplan' With Liberty Lifter

Simple Flying

Ekranoplans (or ground-effect vehicles (GEVs)) are among the most interesting vehicles and combine a boat with a seaplane. DARPA is working to develop an ekranoplan called the Liberty Lifter with a payload capacity similar to the C-17 Globemaster.

Fish Or Fowl: What Is The Liberty Lifter & How Would It Work For The US Navy?

Simple Flying

Ekranoplans, or as they are also forgettably known, ground effect vehicles (GEV), were a major area of study and development during the Soviet Union. It has long been understood that if some formidable engineering challenges can be overcome, ekranoplans could be revolutionary in hybrid sea/airborne transportation.

Coast Guard Clears Ground-Effect Flying Boat For Certification Testing

AV Web

Regent Viceroy The Coast Guard has approved crewed testing of the wing-in-ground-effect Regent Viceroy seaglider and the company is anticipating a speedy trip to certification. The Russians have been dabbling in ground-effect aircraft (or boats) for decades and have made some huge examples.

Beriev Be-2500: What Should You Know About The Proposed Super Heavy Amphibian Ground Effect Plane?

Simple Flying

Ekranoplans are a sort of mix of an aircraft and a hovercraft using ground effect to fly or skim a few meters above the ground (normally the water). It is sometimes assumed that the Soviets just copied Western aircraft design (such as with the Tupolev Tu-4 - a B-29 copy) and were always playing catch-up.

How to fly a perfect soft field approach and landing

Flight Training Central

This allows the airspeed to slowly dissipate while the airplane is flown just above the surface in ground effect. When the wheels first touch the ground, the proper technique allows the wings to continue supporting much of the weight of the airplane.

High Wing or Low Wing – Which Trainer Should I Choose?

Flight Training Central

Short field landings can be shorter because the drag robbing ground effect is lessened by the greater distance between the wing and ground. High wing aircraft are inherently stable as the center of mass is located beneath the center of lift (compare hanging from a rope as compared to sitting on one).
