Research on Improving the Heat Dissipation Ability of Airborne Fuel Heat Sink Based on Aircraft/Engine Integration

This article addresses the issue of insufficient heat sinks due to the rapid increase in aircraft thermal load. It analyzes the challenges faced by existing fuel thermal management and factors affecting the heat dissipation performance of heat sinks. The paper proposes an improved heat dissipation method for fuel heat sinks based on the integration of aircraft and engines. It provides an optimized control strategy for high-temperature return oil to alleviate heat accumulation in fuel tanks. Moreover, a fuel thermal management proxy model for aircraft engines is constructed in combination with application scenarios. Simulation analysis shows that the optimized fuel thermal management scheme has a good effect on improving the efficiency of onboard heat sink utilization, and it has potential application value in practical engineering.
