METHOD OF FILLING AIRCRAFT HYDRAULIC SYSTEM Russian patent published in 2002 - IPC

Abstract RU 2192369 C1

FIELD: aeronautical engineering; flying vehicle hydraulic systems working on oils, type AMГ- (Russia), hydronicoil (France) and other analogs of AMГ-10 oil; various industries. SUBSTANCE: proposed method of filling aircraft hydraulic system consists in ground preparation of working fluid of definite quality, filling the technological tanks for closed filling through quick-detachable joint or on-board quick-acting valve; filling the hydraulic system is also performed during scheduled maintenance (every 300 hours of flight); aircraft hydraulic tanks are filled from technological tanks in small amounts, 10 to 30 l as maximum for replenishing oil losses (spillage and oil drained from filter sleeves); purity of working fluid shall be higher by 2 or 3 classes at kinematic viscosity higher than required viscosity by 2 to 3 cSt. EFFECT: enhanced efficiency of restoration of quality of working fluid at maintained quality. 3 dwg
