在美军试验与鉴定中将仿真模型验证作为其目的之一。结合某型直升机模拟器研制项目,利用该直升机试飞数据,开展直升机动力学仿真模型试飞校验技术的探索。建立该型直升机的部件级仿真模型,用前飞稳态飞行数据对模型中的气动、发动机模块进行稳态对比与修正,校验结果达到了直升机D级模拟器规范ccar60中稳态条款的要求。
In the US military test and identification simulation model validation as one of its purposes. Combined with a helicopter simulator development project, this helicopter flight test data was used to carry out exploration test of helicopter dynamics simulation model flight test. The part-level simulation model of the helicopter is established, and the steady-state comparison and correction of the aerodynamic and engine modules in the model are carried out with the steady-state flight data of the former flight. The verification results meet the requirements of the steady state clauses of the c-class D of the helicopter D-class simulator .
