Although the original Sto-Wing operated with hydraulic cylinders, they added too much weight to the craft, so a model built from lighter materials was developed. trailer << /Size 88 /Info 63 0 R /Root 68 0 R /Prev 474811 /ID[<649b636570b1bb6e1dba9b226e175788><649b636570b1bb6e1dba9b226e175788>] >> startxref 0 %%EOF 68 0 obj << /Type /Catalog /Pages 62 0 R /FICL:Enfocus 64 0 R >> endobj 86 0 obj << /S 255 /Filter /FlateDecode /Length 87 0 R >> stream Most folding theories are concerned with either speed of a stowed mechanism or its … No. No.

A prior bi-fold wing design has been proposed by Schertz (U.S. Pat. ������=��[���P������Ӻ�F5~�̃iݢ̽ ڽTlJai��8^ �N��bpn����҉.z hM֧�.��w3��m�vv���{?�����c Both hinge link no. Some of the prior art does combine a fold with this rotation. 6,076,766) as it provides a more durable and cost-effective method of fairing the surface of the structure. All STEMME aircraft can be ordered with an optional folding mechanism, which reduces the wing span to 11.2 m (37 ft) [S 10] with minimal effort.This light weight allows one person to easily fold the outer wings. This is the approach taken in broad terms by Geisse (U.S. Pat. The mechanism of claim 7 further comprising means to displace the lock from the mechanical stop.

No. Terms of Use When inner wing (50) is fully retracted, the top surface rests up against the exposed edge of aircraft body (24), again sealing the gap between inner wing (50) and aircraft body (24), and protecting the hinge mechanism.

FIG. A Grumman F9F-2 Panther jet on the U.S. aircraft carrier USS Bon Homme. No. 3 (7) and hinge link no. The Wildcat's innovative "Sto-Wing" mechanism developed on the XF4F-4 prototype by Leroy (Roy) Grumman (1895-1982), a founder of Grumman Aircraft Engineering Corporation, was crucial to the U. S. Navy's success during World War II.

As inner wing (50) rotates counterclockwise, front cover panel (25) and rear cover panel (27) also rotate counterclockwise, revealing a cutout in aircraft body (24) that is the same shape as the top surface of inner wing (50).
