Abstract

1,210,451. Retractable undercarriages. MESSIER. 23 April; 1968 [30 May, 1967], No. 19168/68. Addition to 1,111,622. Heading B7G. An aircraft undercarriage leg is retractable about a pivot pin in the fuselage inclined to the plane of symmetry of the fuselage, and a pair of wheels is mounted on an arm pivoted to a shaft rotatably mounted on the leg about an axis parallel to the plane of symmetry. The shaft is arranged to be rotated in a housing 7 as the leg is raised upwardly, inwardly and forwardly during retraction so that the wheels are upright when retracted but inverted relative to their lowered position. The shaft may be rotated by a jack, or by a linkage 21, 17, 15 connecting a crank 14 on the shaft with a fixed point on the fuselage, and hydraulically operated locking means 23 is provided to prevent rotation of the leg about the fuselage pivot until retraction of the undercarriage is desired.
