摘　　要：简要概述了冲压空气涡轮系统在CE-208B飞机上的挂装方案。基于经典的叶素-动量理论,利用Matlab软件计算了试验条件下涡轮叶片的气动特性,得到了对飞机产生的附加力和力矩,然后采用类比法和保守估算法计算分析了挂装冲压空气涡轮后飞机的升阻特性和力矩特性。研究表明,挂装冲压空气涡轮后,飞机的阻力略有增加,飞行性能无明显下降,飞机仍是纵向静稳定的,不会产生过大的滚转角;冲压空气涡轮在CE-208B飞机上挂飞的设计方案合理可行,为后续冲压空气涡轮在真实环境下的试验奠定了基础。The mounting scheme of ram air turbine system on CE-208 B airplane was discussed. Based on blade element momentum theory, the aerodynamic characteristics of the turbine blades under the experimental conditions were calculated using Matlab and the additional force and torque loading on the aircraft were obtained. According to the results, the lift-drag characteristics and the torque characteristics of the aircraft mounted ram air turbine were calculated and analyzed using analogy and conservative estimation methods. The results indicate that the flight performance of the aircraft has not been significantly declined, although the resistance has increased slightly, the aircraft is still longitudinally static and doesn’t produce a too big roll angle. Therefore, the mounting scheme of ram air turbine system on CE-208 B airplane is reasonable and feasible, which provides the foundation for ram air turbine testing in real environment.
