In order to understand the equivalent relationship of a landing gear's sudden-extension test and the real sudden-extension process of a carrier-based aircraft, a dynamics model of a certain carrier-based aircraft catapult-assisted takeoff process is established. The catapult-assisted takeoff dynamics is simulated and the nose landing gears dynamic response to the sudden-extension process is obtained. A test method is introduced to study the nose landing gear's sudden extension based on equivalent mass. Accordingly, a test program is presented for independent nose landing gear sudden-extension analysis. With simulated results of the models introduced above, the value range of relevant test parameters is studied. It is shown that the independent nose landing gear sudden-extension dynamic response is relatively consistent with the full-aircraft catapult-assisted takeoff dynamics when the equivalent mass coefficient is equal to 0.8.
