Aircraft, which are subject to various loads during operation, must fly safely with controllability and redundancy ensured, even under the harshest expected conditions. On the other hand, it takes a significant amount of time and risk to verify by flight tests whether the control surfaces can be operated normally in the presence of a gust and whether the aircraft can continue to fly safely even if a failure occurs during flight. Mitsubishi Heavy Industries, Ltd. (MHI) developed large-scale ground test equipment that can simulate the above conditions and narrowed down the test conditions using the large-scale analysis technology introduced in this report. As a result, we were able to obtain the prospect of completing verification testing in a short period of time. By applying this structure-mechanism-control coupled large-scale analysis technology, it is possible to efficiently evaluate airframe performance in similar developments and to streamline the verification test and accelerate the development process.
