AI Technical Summary

Technical Problem

The existing battery compartments of low-altitude aircraft lack effective thermal runaway protection measures, which makes them prone to combustion and explosion after thermal runaway. In addition, the existing fire extinguishing devices are heavy and bulky, which seriously affects the endurance and inspection capabilities and cannot meet the needs of long-endurance field inspection.

Method used

It adopts a battery compartment integrated intelligent thermal runaway protection system, including a condensation circulation mechanism, a negative pressure filtration system, a fire extinguishing agent injection mechanism, and an edge graphene fire extinguishing blanket. It monitors thermal runaway and provides coordinated protection through multi-dimensional sensors, and uses perfluorohexanone fire extinguishing agent and graphene materials for rapid fire extinguishing and gas treatment.

Benefits of technology

It enables rapid identification and suppression of battery thermal runaway without human intervention, reduces fire extinguishing agent consumption, improves the system's economy and reliability, and ensures the safety and endurance of the aircraft.
