Support structure of UAV (Unmanned Aerial Vehicle) engine is the important support for UAV engine  playing a support role and bearing extremely complex load  so its lightweight  strength and dynamic characteristics have a great influence on high performance of UAV. This paper focuses on UAV having the requirement of high performance and stability to the support structure of engine  and uses the software of MSC.Patran and MSC.Nastran and topology optimization criterion to lightweight design and analysis the support structure of UAV engine under the premise condition of existing constraints. Then the static strength and modal are analyzed for the result of lightweight design  and the strength of the model and dynamic characteristics are verified.
