文中介绍了一种直升机载电子吊舱环控系统。针对直升机吊舱悬停、低速飞行和小型化的特点,本环控系统可以满足直升机吊舱电子设备的供液需求。通过对环控系统的仿真分析和试验验证,仿真与试验的误差小于10%。仿真和试验结果表明:环控系统制冷量随飞行速度的增加而增加,当飞行速度较大时,制冷量的增幅变缓;小负攻角对环控制冷量的影响很小。
In this paper, a helicopter-mounted electronic pod loop control system is introduced. In view of the characteristics of helicopter pod hovering, low-speed flight and miniaturization, the present environmental control system can meet the liquid supply requirements of helicopter pod electronic equipment. Through the simulation analysis and experimental verification of the environmental control system, the error between simulation and experiment is less than 10%. Simulation and experimental results show that the cooling capacity of the system increases with the increase of the flight speed, and the increase of the cooling capacity becomes slower when the flight speed is larger. The effect of the small negative angle of attack on the circulating cooling capacity is small.
