"Invisible" Support in Aerospace —— On Hidden Hinge in Aerospace
In the modern aerospace field, hinge, as one of the key mechanical parts, plays an irreplaceable role in the design and manufacture of aircraft, spacecraft and other aircraft. With the progress of science and technology and the change of design requirements, a new type of structure-aerospace hidden hinge has gradually entered people's field of vision and attracted wide attention because of its unique performance advantages.
1. What is an aerospace hidden hinge?
As the name implies, aerospace hidden hinges refer to those hinge devices that are installed inside or under the surface of the fuselage and realize the opening and closing function without affecting the overall aerodynamic shape. This kind of hinge can not only effectively reduce the wind resistance coefficient, but also improve the flight efficiency; It can also enhance the beauty and concealment of the body and provide more possibilities for performing special tasks.
Second, the characteristics and applications of aerospace hidden hinges
1. High-strength material: In order to meet the requirements of structural stability and reliability in complex environment, aerospace hidden hinges are usually manufactured by high-strength aluminum alloy or titanium alloy;
2. Precision processing: in the manufacturing process, it is often necessary to go through multiple processes such as laser cutting/welding and CNC carving to ensure that the dimensional accuracy meets the standard requirements;
3. Reduce the weight while ensuring the bearing capacity: use ingenious geometric shape optimization to reduce the self-weight burden without sacrificing its bearing capacity;
4. Meet specific environmental conditions: such as high temperature and low temperature resistance (200℃ ~+600 C), anti-corrosion and anti-oxidation and other special material coating technologies, the product can adapt to more diverse application scenarios, such as hypersonic aircraft door opening and closing mechanism, satellite solar panel retracting system, etc.
Third, the future development trend prospect
With the continuous breakthrough of new materials science and the popularization of advanced manufacturing equipment, we have reason to believe that aerospace hidden hinges will develop in a lighter and more intelligent direction in the future, for example, by introducing carbon nanotube composites to further reduce the weight and increase the mechanical properties; Or use the internet of things technology and sensor network to monitor its working state and eliminate hidden troubles in time.
In a word, as an important type of aviation spare parts, aerospace hidden hinge is gradually becoming a research hotspot in the industry with its unique advantages. We expect it to play a greater role in future practical applications!
