The modification of universal testing aircraft is an important support for flight testing

The modification of the test machine begins with the modification of the test. Early aircraft were relatively simple. During test flights, the test pilot mainly relied on the feeling of the test pilot. When maneuverability allowed, the test pilot wrote the instrument numbers on the knee pad. This was the initial "flight test".

With the development of aircraft manufacturing technology, testing flights alone relying on the feeling of a test pilot can no longer meet the needs of aviation development. Starting from installing cameras on aircraft, testing aircraft has been equipped with testing equipment, and modification and testing have thus become an indispensable and important part of flight tests. Because we only installed test equipment on the aircraft at first, the modification of the test aircraft was long called the aircraft (added) modification.

The modern aviation industry is developing in innovation. While carrying out the modification of test machines for model test flight identification, various types of test research machines used for aviation technology research and demonstration and verification of new technology have become an important part of the modification of test machines.

Universal testing machineThe modification requires high technical capabilities in aircraft design, production, system development, testing, etc., and especially emphasizes the ability to have comprehensive engineering. The purpose of the modification of the test machine mainly includes three categories: model test machine, airborne test system, and experimental research machine.
