The ULTIMATE Soaring design
One of GODS creative designs from which ALL models fall short... A tip dragging Albatross!
The wingspans of the largest great albatrosses (genus Diomedea) are the largest of any bird, exceeding 340 cm (11.2 ft), although the other species' wingspans are considerably smaller (1.75 m (5.7 ft)). The wings are stiff and cambered, with thickened streamlined leading edges. Albatrosses travel 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. Slope soaring uses the rising air on the windward side of large waves. Albatross have high glide ratios, around 22:1 to 23:1, meaning that for every metre they drop, they can travel forward 22 metres. They are aided in soaring by a shoulder-lock, a sheet of tendon that locks the wing when fully extended, allowing the wing to be kept outstretched without any muscle expenditure, a morphological adaptation they share with the giant petrels.
