CRYOGENIC PROPELLANT FILLING SYSTEM FOR FLYING VEHICLE Russian patent published in 1995 - IPC

FIELD: aeronautical engineering. SUBSTANCE: system has lifting mechanism 24 of filling coaxial tip 14 with angular motion drive 26 and vertical motion drive 27 which are required for mechanical coupling of lock mechanism 25 of tip 14 with coaxial filling pipe union 15 of aircraft 16. Tip 14 is fitted on filling pipe line 13 embraced by additional pipe line combining filling line 6 and drainage line 20 which are respectively connected with neutral gas system through heat exchanger 31 and centralized vapor discharge and recovery facilities 23. EFFECT: improved service characteristics through enhanced safety, ease of use, reduction of filling time, as well as discharge and recovery of carried-off vapor. 2 cl, 1 dwg
