The high-profile 15th China International Aviation and Aerospace Exhibition kicked off at the Zhuhai International Air Show Center on November 12. A series of advanced weapons and equipment will appear in a "pile". The exhibits cover the whole field of "land, sea, air, space, electricity, and network", including "high, refined, and sophisticated" exhibits such as the J-20S and J-35A. For the first time, it attracted over 890 companies from 47 countries and regions to participate in the exhibition.
This year's air show not only showcased innovative achievements in China's aerospace and defense fields, but also attracted numerous internationally renowned aviation companies to participate. Overseas exhibitors increased by 91% compared to the previous edition, further enhancing the level of internationalization. At the same time, flight performances and dynamic demonstrations of ground equipment are also important highlights of this air show.
The China Aerospace Exhibition is an international professional aviation and aerospace exhibition approved by the Central People's Government to be held in Zhuhai, China. Its main features include physical display, trade negotiations, academic exchanges, flight performances, and dynamic demonstrations of ground equipment. It has now developed into a blue sky event that integrates trade, professionalism, and viewing, representing the advanced technology mainstream of the international aerospace industry today, showcasing the development level of the world'saerospace industry, and ranking among the five major air shows in the world.
The application of sensors in the aerospace field is extensive and critical, mainly reflected in the following aspects:
Navigation and positioning: Real time tracking and recording of the aircraft's position, speed, and direction through technologies such as GPS or inertial navigation systems, ensuring flight safety and precise navigation.
Meteorological monitoring: Sensing meteorological information such as temperature, humidity, pressure, wind speed, and direction in the atmosphere, helping pilots and ground control centers understand weather conditions and make decisions, and improving flight safety.
Structural health monitoring: Real time monitoring of structural parameters such as stress, strain, and vibration of the aircraft to ensure its structural safety and reliability.
Fuel monitoring measures parameters such as fuel level, flow rate, and temperature to help understand fuel usage and adjust fuel supply strategies in a timely manner.
Pressure monitoring: plays an important role in aircraft cabin pressure regulation, emergency oxygen supply, and monitoring of spacecraft cylinder pressure and engine intake pressure.
These applications collectively ensure the safe, stable, and efficient conduct of aerospace activities.
The high temperature vibration sensors 372P and 375PA from Senther Technology can reach a maximum temperature of 485 degrees Celsius, and can be used as a complete set with a high temperature wire 17PH and a special high temperature charge amplifier IN-17; The maximum temperature of 337P can reach 650 degrees. The shell is made of high-temperature alloy and the sealing of the product is achieved through laser welding technology; The cable output connector adopts a miniature glass insulated connector to meet the stability of output in different environments, and is used in combination with 11P special high-temperature wire and special high-temperature charge amplifier IN-17. The Senther high-temperature vibration sensor adopts high-temperature resistant materials and special structural design to ensure stable performance even in high-temperature environments. In addition, the Senther high-temperature vibration sensor should have good anti-interference ability and high sensitivity (when used together with a charge amplifier) to accurately monitor the vibration status of aircraft engines.
In general, the application of high-temperature vibration sensors in aircraft engines and hypersonic engines can improve the reliability, safety, and performance of the engines, ensuring safety and the normal operation of the equipment. Therefore, high-temperature vibration sensors have important application value in aviation engines and hypersonic engines.
