摘要
基于复合翼eVTOL推力单元散热需求,通过CFD分析了4种散热气道内空气的流速,选择满足散热需求的散热气道;设计推力单元和散热气道的安装结构,采用有限元方法计算电机臂和电机座的结构应变和应力,结果满足结构的强度要求。通过台架试验、地面压载试验和飞行试验,验证推力单元安装散热一体化设计的可行性,填补了国内复合翼eVTOL推力单元利用前行空气来流进行散热与安装设计的空白。
Based on the heat dissipation requirements of the hybrid wing eVTOL thrust unit,the air flow velocity in four types of heat dissipation ducts is analyzed using CFD.The heat dissipation duct that meets the heat dissipation requirements is selected.The installation structure of the thrust unit is designed and heat dissipation duct is used finite element method to calculate the structural strain and stress of the motor arm and motor seat.It meets the strength requirements of the structure;verifies the feasibility of integrated heat dissipation design for thrust unit installation through bench tests,ground load tests,and flight tests;fills the gap in domestic hybrid wing eVTOL thrust units that utilize forward air flow for heat dissipation and installation design.
