1,241,827. Retractable refuelling probe. BRITISH AIRCRAFT CORP. Ltd. 28 July, 1969 [29 July, 1968], No. 36090/68. Heading B7G. [Also in Division F2] An in-flight aircraft refuelling probe 12 has telescoping tubes 18, 20, extension of which pivots the probe 12 from a position in a recess 14 adjacent the cockpit to the position shown where the probe tip 60 may engage a tanker aircraft drogue, the pivoting action being due to a strut 30 whose point of engagement 34 with the tube 20 lies further from the aircraft than the probe and strut pivot points 22 and 32 respectively. Probe extension and retraction is effected by an hydraulic cylinder 28 surrounding the tube 18 and coacting with an annular piston (26, Fig. 5, not shown) on the tube 20. The probe carries a recess cover 16. |
