Abstract
The test of arresting hook bounce is one of the most essential technologies in the design and research of arresting hook. In order to research the dynamic performance of the hook after touchdown and impacting with the deck when the aircraft is arrested, an approach for a certain type of aircraft arresting hook bounce test is proposed in this paper. Solutions to critical technique issues arising in the test process such as aircraft sinking velocity control, aircraft horizontal velocity simulation, and simulation of the performance of the damper are derived and verified by the bounce test of the arresting hook. The bounce height, bounce distance, stroke length of the arresting hook damper after the hook is impacted are measured by the test. The test method proposed can be used for researching the bounce of arresting hook and providing reliable test data for the design of carrier-based aircraft and arresting hook.
Highlights
The arresting hook is a significant difference between the carrier-based aircraft and the land-based aircraft
In order to study and test the bounce height and impact load when the arresting hook collides with the deck in the landing process, it is necessary to conduct a comprehensive assessment of the collision dynamic performance of the arresting hook in the laboratory environment through the collision rebound test of the arresting hook
It is necessary to simulate the actual landing conditions, The collision rebound test of the arresting hook is a test of the collision dynamic performance in including landing attitude, landing gear cushioning performance, sinking velocity, horizontal the laboratory environment
Summary
The arresting hook is a significant difference between the carrier-based aircraft and the land-based aircraft. The arresting hook firstly collides with the deck when the carrier aircraft lands, and the bounce in limited height occurs under the action of the arresting hook longitudinal damper [2]. When the arresting hook collides with the deck, both the arresting hook assembly and its connection are in the working environment of dynamic impact load, and the loading form becomes very complex, which makes the load analysis of the arresting hook very difficult. In order to study and test the bounce height and impact load when the arresting hook collides with the deck in the landing process, it is necessary to conduct a comprehensive assessment of the collision dynamic performance of the arresting hook in the laboratory environment through the collision rebound test of the arresting hook.
