Description

Technical Field

[0001] This invention belongs to the field of comprehensive testing technology for electromagnetic clip hooks on hangers, specifically relating to a general-purpose comprehensive testing system for electromagnetic clip hooks on hangers. Background Technology

[0002] The GDG-Ⅱ13 series electromagnetic missile hooks (including the GDG-Ⅱ13 electromagnetic missile hook, GDG-Ⅱ13A electromagnetic missile hook, and GDG-Ⅱ13B electromagnetic missile hook) of the helicopter universal pylon weapon system are key components of the external load system and core components of the helicopter external load weapon system. The reliability of the electromagnetic missile hooks is directly related to the safety of transport.

[0003] Due to varying storage and usage environments, harsh conditions can easily lead to insufficient flexibility in the product's movement mechanism. Differences in the skill levels of maintenance personnel during loading and unloading operations can also cause varying degrees of reliability degradation. Currently, maintenance of the missile hook only includes oiling, visual inspection, and no-load functional checks; it's impossible to perform functional and performance checks and quantitative assessments under load. The lack of pre-loading functional performance verification methods prevents a full-state inspection of various externally mounted weapons, posing a hidden safety risk. Furthermore, the absence of relevant testing and evaluation methods makes a full-state inspection of the electromagnetic missile hook impossible. If installed and used under these conditions, serious consequences of accidental release may occur during routine flight training, and in emergencies, release failure may occur, directly impacting the safety of personnel and equipment.
