Document Type and Number:
Japanese Patent JPH03503148
Kind Code:
A
Abstract:
A quick change wheel landing gear assembly (10) is provided as a replacement for a skid landing gear system on a vertical take-off and landing aircraft. The wheel landing gear assembly (10) includes a pair of spaced-apart fore and aft longitudinal tubes (16, 18) attached to a pair of short, spaced-apart cross tubes (20, 22) that are adapted to mount on the structural saddles (12, 14) used to mount the skid landing gear on the underside of the aircraft. The longitudinal tubes (16, 18) are connected together at the forward end for mounting a fully swiveling nose gear (26) thereto. Aft main gear wheels (30, 32) are mounted on cantilever landing gear legs (34, 36) that extend laterally from the longitudinal tubes (16, 18) adjacent the aft cross tube (22). Landing loads on the landing gear may be absorbed by resilient springs (25), deflection of the gear legs (34, 36) and the aft cross tube (22), torsion of the fore and aft longitudinal tubes (16, 18), or any combination of these actions. The wheel landing gear assembly (10) is designed to be mounted on existing aircraft structural saddles which eliminates the need for special landing support structure needed in the prior art.
