急需高手幫航空英文翻譯~謝(20點)

Fuel supply is contained in five Cells interconnected to act as a single tank.Three cells are located across fuselage below engine deck,with system filler cap on riht-hand cell.Two forward cells located under cabin floor and gravity fed from aft cells,are each provided with a fuel boost pump.On helicopters prior to serial no.69-15292,the right pump is electrically operated and the left pump is driven by bleed air from engine compressor.Helicopters Serial no.69-15292 and subsequent have electrically operated boost pumps in both the right and left forward cells.Fuel under pressure is delivered from pumps through separate lines to a check valve manifold on front of engine firewall.Passing through two check valves and single outlet of manifold,fuel flows through an electrically controlled shutoff valve to main fuel strainer in engine compartment for delivery to engine through fuel controlled inlet hose.Fuel shutoff valve and each check valve of manifold have internal bypass valves,to relieve thermal expansion of trapped fuel when system is inoperative.Transmitter for fuel pressure gage is connected to a tap on check valve manifold.

請大大幫幫忙~合理答案贈20點!!謝謝︿︿

    燃料提供是由5個油室相互連接成一個油箱。 3 個油室橫跨機身置於發動機座下,加油孔是在右油室。兩個前面油室則位於駕駛艙下和重力集中在後面油室,每個油室配有燃油增壓幫浦。在69-15292以前系列的直昇機,右油室幫浦是電動操控,而左油室幫浦則是由發動機壓縮機氣流驅動。69-15292以後的直昇機左右油室幫浦都是電動操控。燃料利用壓力由幫浦經獨立線路到發動機防火牆前的檢查閥歧管。燃料在流經兩個檢查閥和單獨的歧管口後,再流過一個電力控制的關斷閥到發動機室主燃料過濾器,然後經燃油控制口送到發動機。燃料關斷閥和每個個歧管的檢查閥門都有內部支流閥,這個內部支流閥把主要功能是釋放因系統無法操作時產生的燃油熱膨脹。 燃料壓力計的發送器是連接到歧管檢查閥的分接頭。
