基于模型测试方法在模拟器客观评估中的应用

逼真度反映飞行模拟器与真实飞机特性的一致性程度。 客观评估是一种通过模拟器与系统实际行为的测试比较来评估逼真度的工程方法。 飞行模拟器分为工程模拟器和训练模拟器。 用于飞行训练的训练模拟器构型很少变化,其测试用例由适航标准指导,而用于设计验证的工程模拟器,根据飞机研制进展经常需要升级或更改,其测试用例也会随之变化。 在当今民用飞机技术日趋复杂的背景下,亟需高效方法开展这一类型模拟器的逼真度客观评估测试。 在实验框架和系统实体结构和模型库框架的基础上,提出了一种基于模型测试的方法,在工程模拟器的客观评估的应用中,该方法可以实现测试用例的自动生成和执行,工作效率提升,流程具备灵活性和适应性,有助于在研飞机的定型或取证。

Model-based testing for objective test of flight simulators

Fidelity reflects the consistency between flight simulator and real aircraft characteristics. Objective evaluation is an engineering method to evaluate the fidelity by comparing the simulator with the actual behavior of the system. Flight simulators are divided into engineering simulators and training simulators. The configuration of the training simulator used for flight training rarely changes, and its test cases are guided by airworthiness standards. However, the engineering simulator used for design verification often needs to be upgraded or changed according to the aircraft development progress, and its test cases will also change. Under the background of the increasingly complex technology of civil aircraft, it is urgent to develop an efficient method to objectively evaluate the fidelity of this type of simulator. Under the background of the increasingly complex technology of civil aircraft, it is urgent to carry out the objective evaluation and test of the fidelity of this type of simulator. Based on the experimental framework, system entity structure and model base framework, this paper proposes a model-based testing method. In the application of objective evaluation of engineering simulator, this method can realize the automatic generation and execution of test cases, improve the work efficiency, and have flexibility and adaptability in the process. It is helpful to the finalization or certification of aircraft under development.
