燃油箱燃油连通管的出流能力研究

本文研究了直升机加油过程中燃油箱通油连通管出流能力的两种计算方法:一是将连通管的流动型式全部假定为孔口出流进行计算;一是将连通管的流动型式细分为堰流及孔口出流,并建立弓形堰的出流计算公式进行计算,对这两种计算结果的差异进行了比较,供实际应用时参考.

Study on Outflow Capacity of Connected Pipe between Fuel Tank

That two methods are used to calculate outflow capacity of connected pipe between fuel tank during refueling is developed.One is to suppose that shape of all the fuel flow in connected pipe is orifice flow and calculate outflow capacity;the other is to that the fuel flow in connected pipe has two shapes,namely,orifice flow and weir flow,found formula of arched weir outflow calculation and calculate outflow capacity.A case study was presented to illustrate the two methods.
