Abstract
1333200 Aircraft undercarriages BRITISH AIRCRAFT CORP Ltd 23 May 1972 [26 May 1971] 17094/71 Heading B7G An aircraft undercarriage comprises a leg 3 pivoted at 2 to structure 1 for fore-and-aft movement, a bracing strut 4 and a locking strut 8. The parts 4a, 4b of strut 4 are connected by pivot 5 which also provides one connection for part 8a of strut 8, the other part 8b being connected at 10 to leg 3 and at 14 to a retraction jack 12. A spring box 11 biases strut 8 into its extended position. In operation, to retract the undercarriage from the position shown in Fig. 1, to that shown in Fig. 3, the jack is contracted, thereby breaking the joint of strut 8 against the action of the spring box 11 which in turn breaks the joint of strut 4 and draws the leg 3 upwardly to the retracted position. When retraction is complete the spring box causes strut 8 to re-assume its extended position as shown in Fig. 3, thereby holding the undercarriage retracted.
