Abstract

A landing gear consists of a pair of longitudinal skid members 3,3a mounted for sideways lowering and retraction, and arranged, in the retracted position, to form fairings closing the lower portion 10 of the fuselage. Each skid unit includes a ground‐engaging member 6 attached by links 16, 17, 16a, 17a, and a transverse pin 11 to an upper member 4 supported by lugs 8, 9 secured to a rotatable longitudinal shaft 35. The skid 6 may pivot about the pin 11 under the constraint of rubber‐disk shock absorber 21. The shaft 35 is provided with a torsional shock‐absorber consisting of a scries of rubber annuli 44, the opposite faces of each of which is bonded to a pair of metal disks, one of which has internal teeth engaging splines 36, FIG. 2, on the shaft 35, while the other has external dogs 50, 51, 52 engageable with stops 53, 54, 55 projecting inwardly from a fixed casing 43 to render the shock‐absorber effective against rotation of the shaft 35 in one direction. Each skid unit is operated by a jack 66 which rotates the unit into the vertical position shown in FIG. 3 and in so doing causes abutment of the dogs 50, 51, 52 against the stops 53, 54, 55. Under load outward splaying of the skid units is permitted by pin and slot connections 67,68 between the ends of the jacks 66 and the units under the constraint of the torsional shock‐absorbers.
