Dynamic soaring is a flying technique used to gain energy by repeatedly crossing the boundary between air masses of significantly different velocity. Such zones of high wind gradient are generally found close to obstacles and close to the surface, so the technique is mainly of use to birds and operators of radio-controlled gliders, but glider pilots have occasionally been able to soar dynamically in meteorological wind shears at higher altitudes. The highest speeds reported are by radio controlled gliders at over 498 mph (801 km/h).
Dynamic soaring is sometimes confused with controllable slope soaring which uses a similar but different technique for achieving elevation.
... In the late 1990s, radio-controlled gliding awoke to the idea of dynamic soaring (a "discovery" largely credited to RC soaring luminary Joe Wurts) ... Radio controlled glider pilots perform dynamic soaring using the leeward side of ground features such as ridges and saddles ... Because of this, dynamic soaring models are commonly built using composite materials ...
... accurate airspeed measurement in order to perform the dynamic gliding manoeuver ... huge distances with two techniques used by many long-winged seabirds, dynamic soaring and slope soaring ... Dynamic soaring involves repeatedly rising into wind and descending downwind thus gaining energy from the vertical wind gradient ...
... In dynamic soaring energy is gained by repeatedly crossing the boundary between air masses of different horizontal velocity rather than by rising air ...
Famous quotes containing the words soaring and/or dynamic:
“O Holy Wisdom, Soaring Power, encompass us with wings unfurled,
and carry us, encircling all, above, below, and through the world.”
—Hildegard Von Bingen (10781179)
“Magic is the envelopment and coercion of the objective world by the ego; it is a dynamic subjectivism. Religion is the coercion of the ego by gods and spirits who are objectively conceived beings in control of nature and man.”
—Richard Chase (b. 1914)
