AI Technical Summary
In high-altitude environments, the antifreeze in water-based counterweight systems condenses at low temperatures, reducing system fluidity and preventing normal operation. Furthermore, traditional heating methods are inefficient, require large amounts of power, and may lead to oxidation.
Temperature sensors are installed to monitor the temperature of the non-pressurized compartment. The temperature is controlled in real time using the exhaust gas from the pressurized compartment and the hot air from the bleed air inlet of the environmental control system. The temperature of the non-pressurized compartment is adjusted to prevent antifreeze from condensing. A combination of exhaust valves and bleed air check valves is used for control.
It effectively prevents antifreeze from condensing, improves system heating efficiency, reduces power demand, ensures the aircraft's center of gravity adjustment capability, and avoids the defects of traditional heating methods.
