摘　　要：针对数字孪生在飞行试验中的应用问题,对数字孪生的内涵和特点进行研究分析,利用试飞对象行为和性能的映射,完成飞行试验需求开发与总体规划、试飞任务设计、一体化测试改装、试飞组织实施、快速维修保障、试飞工程师培训6个试飞数字孪生典型应用场景设计,实现了试飞过程中数字模型和物理实体间的同步更新、并行验证和螺旋演进,构建了"预测-飞行-比较"智能试飞模式,是飞行试验数字孪生的工程应用突破。For the application of digital twins in flight tests, the connotation and technical characteristics of digital twins were studied and analyzed. Six flight test digital twins typical application scenarios, such as the requirements development and overall planning of flight test, the flight test mission designing, the integrated testing and modification of flight test, the flight test organization and implementation, the fast maintenance and support and the training of flight test engineers have been designed by mapping the behavior and performance of flight test objects. The synchronize updates, parallel validation and spiral evolution were achieved between the digital models and physical objects during the flight test. The intelligent flight test mode of prediction-flight test-comparison was built. It was an breakthrough in engineering applications of flight test digital twins.
