Beschreibung
Zusammenfassung:	The invention belongs to the field of floating aircrafts, and particularly relates to a method for calculating a flow coefficient of an airship helium valve and measuring the flow coefficient on the ground. The calculation method comprises the steps that the actual helium discharging amount of the helium valve is calculated by measuring the heavy buoyancy change before and after helium discharging of the airship, and then the flow coefficient of the helium valve is solved according to a flow calculation model. 本发明属于浮空飞行器领域，特别涉及一种飞艇氦气阀流量系数的计算及在地面测量方法。计算方法包括：通过测量飞艇排氦前后的重浮力变化计算氦气阀实际排氦量，进而依据流量计算模型求解氦气阀流量系数。
