Abstract:

An in-house program was conducted to derive a method for rapid refueling of Army helicopters. The objective was to devise a system which would permit refueling of helicopters while engines and rotors were operating without the risk of fuel contamination or the hazard of fire. A closed system utilizing a dry-break coupling between fuel hose nozzle and aircraft was deemed to offer potential. Experimental models were fabricated and tested and modifications were made to the models in areas where test results indicated that deficiencies existed. Tests and modifications continued until design characteristics for a prototype model were finalized. Design characteristics are as follows 1 automatic-shutoff device, 2 quick-connectdisconnect dry-break coupling between aircraft adapter and nozzle, 3 conventional refueling capability, 4 simplified system for field retrofit. Ten prototype units were fabricated for military potential test purposes. The tests showed that the automatic-shutoff closed-circuit refueling system has military potential and will meet the program objective. It is concluded that the effectiveness of helicopters as assault vehicles can be improved through the use of this system.
