摘　　要：根据飞行条件和结冰气象条件与风挡防冰需用热载荷的关系,提出评价防冰严酷设计状态的指数——严酷度评估指数,与传统确定严酷状态的方法相比,减少了系统的计算工作量,提高系统的计算效率,具有一定的应用价值。According to windshield anti-icing heat load＇s relationship with the flight conditions and the icing conditions, the severity evaluation index which is used to estimate the anti-icing adverse condition is presented. Compared to the traditional method, the method of the paper can reduce the calculation workload, improve the computational efficiency. Selection of the most adverse condition of windshield anti-icing has certain engineering application value.
