|
摘要
利用飞机/涡扇发动机一体化设计方法,建立了高空长航时无人机涡扇发动机一体化分析模型。基于高空长航时无人机的任务剖面,对约束条件和涡扇发动机模型进行了给定,并根据经验对高空长航时无人机的升阻特性和空重比进行了预测,对高空长航时无人机进行了约束分析、任务分析和任务评估。计算结果表明,建立的高空长航时无人机/涡扇发动机一体化模型具有工程应用价值。
By using the method of aircraft and turbofan engine integrated analysis,a model of high altitude long endurance unmanned air vehicle( HALE UAV) and turbofan engine integrated design was established. Based on the mission section,the constrain conditions,the model of turbofan engine used in HALE UAV was presented. The lift to drag ratio and the empty weight to total weight ratio of HALE UAV was given experimentally. At last,the constrain analysis,the mission analysis and the mission estimation was carried out. The results indicate that the model of HALE UAV and turbofan engine integrated design is feasible and available.
