Integrated muffler dedicated for uavs based on additive manufacturing

Abstract

The invention relates to the technical field of unmanned aerial vehicles (UAVs), specifically an integrated muffler dedicated for UAVs based on additive manufacturing. The muffler adopts a three-stage functional structure consisting of an expansion cavity, a reflective wall, and a porous sound-absorbing material. Each partition has clear functions and cooperates synergistically to jointly achieve efficient flow guiding, noise reduction, and rectification of exhaust gas. The application provides a lightweight and high-efficiency extended-range UAV muffler based on additive manufacturing, which can achieve full-band noise reduction while balancing lightweight and structural strength, improving the practicality and environmental friendliness of extended-range UAVs.
