At 4:27 am Beijing time on October 30, 2024, the Long March 2F Y19 carrier rocket carrying the Shenzhou-19 manned spacecraft was ignited and launched from the Jiuquan Satellite Launch Center. About 10 minutes later, the Shenzhou-19 manned spacecraft successfully separated from the rocket and entered the predetermined orbit. The crew was in good condition and the launch was a complete success.
At 01:24 on November 4th, the return capsule of the Shenzhou 18 manned spacecraft successfully landed at the Dongfeng landing site. On site medical supervision and medical insurance personnel confirmed that astronauts Ye Guangfu, Li Cong, and Li Guangsu were in good physical condition, and the Shenzhou 18 manned flight mission was a complete success.
With the continuous development of technology, the development of China's aerospace industry is getting better and better, mainly reflected in these aspects: 1. Launch of carrier rockets and satellites 2. Manned spaceflight and lunar exploration projects 3. Construction of space stations 4. Civil aviation. These achievements demonstrate China's strength in the aerospace field and are an important manifestation of China's technological rise. So sensors play a crucial role in the aerospace field, mainly reflected in the following aspects:
1. Monitoring and controlling the flight environment: Sensors are used to monitor various pressure parameters of aircraft and spacecraft, such as cabin pressure, cylinder pressure, engine intake pressure, etc. For example, the KELLER pressure sensor 10L can monitor and adjust cabin pressure to ensure the suitability of the flight environment.
2. Ensuring flight safety: Sensors detect pressure changes in rocket thrusters and other aspects to ensure the safe and stable operation of aircraft and spacecraft. In the control system, power system, propellant utilization system, and telemetry system of a carrier rocket, sensors ensure the accuracy and reliability of measurements, thereby ensuring the success rate of the mission.
3. Provide navigation and positioning information: Inertial sensors, such as accelerometers and gyroscopes, are used to measure the linear acceleration and angular velocity of spacecraft, and provide position and velocity information through integration operations. These data are an important component of inertial navigation systems and are widely used in navigation systems for spacecraft such as aircraft, missiles, and satellites.
4. Improve system diagnostic and self checking capabilities: Sensors can provide the necessary information for system wide self checking, verify design schemes and the coordination of various subsystems, and provide decision-making basis for commanders. For example, the variety and quantity of sensors used on the US space shuttle ensure the reliability and safety of the system.
5. Adapt to harsh working environments: The working conditions of aircraft engines are complex and harsh, requiring extremely high performance and reliability of sensors. Therefore, the technical and process requirements for aviation sensors are much higher than those for sensors in other fields.
In summary, the application of sensors in the aerospace field not only involves monitoring and controlling the flight environment, but also involves multiple aspects such as navigation, positioning, safety assurance, and system self checking. The requirements for high precision, high reliability, and high stability makesensors indispensable in the aerospace field.
