Abstract

In a retractable aircraft undercarriage in which an articulated radius rod 6, 8 has one of its lengths 8 pivoted about an axis 9 for retracting or extending the undercarriage, the length 8 is formed with an arm 10 connected by a link 12 or its equivalent to the moving part 16 of a fixedly aligned jack, the part 16 being guided in the fixed alignment. As shown, a landing wheel 2 is carried between cross braced shock‐absorber members 1 articulated at 3 to the aircraft wing structure. The radius‐rod 6, 8 is pivoted to the shock‐absorber at 5 and to the wing at 9. The part 16 is guided on a fixed stem 15, of a hydraulic jack 14, the stem is mounted between swing spars 17, 18. The wing is provided with a lined cavity 4n to receive the wheel when retracted. Locking and indicating means may be provided.
