<p>A telescoping tube (42) for fuel transfer operations, this tube (42) comprising a fixed part (41 ) and a moving part (40), such that this moving part (40) comprises in turn means for dynamic sealing (21 ) which guarantee the sealing of the moving part (40) against the fixed part (41 ), means of cushioning (22) which absorb the energy of the impact of the moving part (40) against the fixed part (41 ) in operations for extending and retracting the tube (42) and means of protection (23) against electrical discharges which earth the moving part (40) to the fixed part (41 ), the aforementioned means (21, 22 and 23) all being incorporated in a single unit in the moving part (40) of the telescoping tube (42), hence providing the aforementioned moving part (40) with all the aforementioned characteristics in a compact form, with the minimum weight and length. Additionally, the invention relates to an in-flight refuelling system for a tanker aeroplane, to carry out in¬ flight fuel transfer operations to a receiving aircraft, which comprises a telescoping tube (42) with the abovementioned characteristics.</p> |
