In the aerospace field, every detail is crucial. And a small handle seems insignificant, but in fact it is related to the safety and reliability of the whole aircraft. As an important operating part, the precision handle of aerospace equipment plays an irreplaceable role in ensuring the life safety of astronauts and successfully completing tasks.
First, the importance of precision handles for aerospace equipment
1. Safety: Precision handlebars are directly related to the convenience and accuracy of astronauts' operation, and have a direct impact on the life safety of personnel in an emergency.
2. Functionality: It not only needs to realize basic functions such as opening and closing doors, but also can accurately complete various complex mechanical actions, such as adjusting the position of instruments.
3. Durability: Considering the use requirements in extreme environment (high temperature/low temperature, vacuum), the precision handle must have extremely high durability and corrosion resistance.
Second, the design requirements and characteristics
Material selection: titanium alloy or aluminum alloy is usually used as the main material, which is light in texture but high in strength and has good oxidation resistance;
Structural optimization: in order to adapt to the special conditions in space, its internal structure is often carefully calculated to ensure sufficient stability and reliability;
Humanized design: considering the different needs of users in different countries and regions, the shape, size and grip feel of the handle need to be carefully considered;
Surface treatment technology: the anti-corrosion effect can be improved by plating and other means, and the aesthetics can also be increased.
Third, the application scenario analysis
(1) Precision handle on the cockpit control panel
It is mainly used to control various preparatory work before taking off, such as opening doors, checking instrument panels and other important steps; In addition, in the execution of certain procedures (such as emergency landing), it is also necessary to rely on such equipment for accurate operation.
(2) Precision handle in external operation toolbox
When astronauts leave the cabin to perform maintenance tasks, they will use such products to open the toolbox to pick up and put the needed items; At the same time, it can help them to fix themselves more firmly to avoid accidents caused by weightlessness.
(3) Precision handles used in the laboratory
Used for the switching operation of laboratory equipment, such as adjusting the focal length of microscope or starting a specific device for scientific experiments, etc. There may be additional function keys on these handles to help users switch modes quickly.
Fourth, the future development trend
With the progress and development of science and technology, the requirements for all kinds of accessories on aircraft will also increase day by day:
More intelligent design can reduce human error rate and improve work efficiency;
The application of high-precision machining technology enables each part to achieve the best matching degree, thus prolonging the service life;
The concept of green environmental protection is deeply rooted in people's hearts, which urges enterprises to actively seek renewable resources to replace traditional materials, reduce production costs and reduce environmental pollution problems.
In a word, the precision handle of aerospace equipment is small but it is related to the overall situation. Only by continuous innovation and improvement can we meet the ever-changing needs and provide more possibilities for human beings to explore the universe!
