The unmanned aerial vehicle landing gear independently developed by the company is based on three-dimensional weaving technology to achieve integrated molding. The structure is non layered and the fiber direction has high designability, which can flexibly manufacture complex configurations such as variable cross-section and variable thickness. This product has the advantages of high fiber coverage, good fiber continuity, low overall porosity, excellent sealing and moisture resistance. The surface of the landing gear is smooth, with high dimensional accuracy and stable consistency. While ensuring structural performance and reliability, it also has the comprehensive advantages of high production efficiency and low cost.
