Comparison of Compensation Losses Between Two Types of Helicopter Multi-Bay Fuel Tank Inerting Systems
For a certain type of helicopter multi-bay fuel tank,a multi-bay fuel tank inerting system using cooling air to control temperature and a multi-bay fuel tank inerting system using fuel heat sink to control temperature are designed.The two models are built based on AMESim platform to study the temperature control effect of the two systems and the variation law of tank parameters of each bay,and the performance of the two systems is evaluated by introducing compen-satory loss index.The simulation results show that both inerting systems can maintain the bleed air temperature at 90℃.The maximum fuel temperature in each bay is less than 32℃and does not exceed the allowable limit during the whole flight.For helicopters,due to the smaller size of fuel tank compared with large passenger aircrafts,it can be calculated that the fuel compensation loss of the multi-bay fuel tank inerting system using cooling air to control temperature is less than that of the multi-bay fuel tank inerting system using fuel heat sink to control temperature.The results can be pro-vided as a reference for design and optimization of the multi-bay fuel tank inerting system.
