WebEtymology []. From French vol plané (“ gliding flight ”).. Pronunciation []. IPA (): /ˈvɒlpleɪn/; Noun []. volplane (plural volplanes) . A steep, controlled dive, especially by an aircraft with the engine off.; Verb []. volplane (third-person singular simple present volplanes, present participle volplaning, simple past and past participle volplaned) . To perform a volplane. Gliding flight is heavier-than-air flight without the use of thrust; the term volplaning also refers to this mode of flight in animals. It is employed by gliding animals and by aircraft such as gliders. This mode of flight involves flying a significant distance horizontally compared to its descent and therefore can … See more Most winged aircraft can glide to some extent, but there are several types of aircraft designed to glide: • Glider, also known as a sailplane • Hang glider See more Three principal forces act on aircraft and animals when gliding: • weight – gravity acts in the downwards direction • lift – acts perpendicularly to the vector representing airspeed • drag – acts parallel to the vector representing the airspeed See more When flown at a constant speed in still air a glider moves forwards a certain distance for a certain distance downwards. The ratio of the distance forwards to downwards is called the glide ratio. The glide ratio (E) is numerically equal to the lift-to-drag ratio under … See more Birds A number of animals have separately evolved gliding many times, without any single ancestor. Birds in particular use gliding flight to … See more The lift-to-drag ratio, or L/D ratio, is the amount of lift generated by a wing or vehicle, divided by the drag it creates by moving through the air. A higher or more favourable L/D ratio … See more Induced drag is caused by the generation of lift by the wing. Lift generated by a wing is perpendicular to the relative wind, but since wings … See more Although the best glide ratio is important when measuring the performance of a gliding aircraft, its glide ratio at a range of speeds also determines its success (see article on gliding).
