The Star Of Change In Innovation-Driven Aviation Systems: 15 ° C Phase Change Materials For Military Aviation

Description:

• 15℃ phase change material for military aviation provides effective temperature control and protection for military aviation equipment through its unique phase change characteristics and temperature regulation mechanism, which is of great significance for improving the performance, reliability and safety of military aircraft.

Advantages of phase change materials for military aviation:
1. Efficient temperature control

• The phase transition occurs when the temperature reaches 15 °C, which can absorb or release a lot of heat according to the change of ambient temperature, so as to effectively maintain the relative stability of the temperature around military aviation equipment.
• Whether it is in a high-altitude low-temperature environment or when the equipment is running hot, it can play a good temperature regulation role to ensure the normal operation and stable performance of the equipment.
• For example, in the aircraft electronic equipment compartment, equipment failure due to too high or too low temperature can be prevented.
• This highly efficient temperature control capability can reduce the dependence of aviation equipment on additional temperature control systems and reduce energy consumption, which is important for military aircraft such as energy efficiency requirements.

2. Small volume change

• During the phase transition, the volume of the material changes relatively little.
• This allows the material to be used in military aircraft without causing additional stress or damage to the structure and equipment of the aircraft due to excessive volume changes, ensuring the structural integrity and safety of the aircraft.

3. High reliability

• After rigorous screening and testing, it can adapt to complex and harsh environmental conditions in the field of military aviation.
• It has good chemical stability and thermal stability, and is not easy to decompose and deteriorate during long-term use, ensuring its reliability and service life in the aviation field.

Common application scenarios and their working effects:
1. Avionics temperature control

• When the electronic device works to raise the temperature to about 15 °C, the phase change material changes from a solid to a liquid state, absorbing a lot of heat and preventing the device from becoming too hot.
• When the aircraft climbs to a high altitude and the ambient temperature decreases, the phase change material changes from liquid to solid, releasing heat and maintaining the temperature stability of the electronic device.
• In this way, the working temperature of the electronic equipment is effectively reduced, for example, the maximum working temperature of the equipment can be reduced by 10-15 °C, which greatly improves the reliability and service life of the electronic equipment.

2. Aeronautical power system thermal management

• In the early stage of engine operation, the temperature gradually rises, and when it reaches 15 °C, the phase change material absorbs heat and slows down the temperature rise.
• When the engine is in a high load working state and the temperature rises further, the phase change material continues to absorb heat, assist the conventional cooling system to work and reduce the temperature of the key parts of the engine.
• When the engine stops working or is in a low load state and the temperature drops, the phase change material releases heat to reduce the thermal stress caused by sudden temperature changes in the engine components.
• This thermal management method can effectively reduce the temperature fluctuation amplitude of the key parts of the engine, such as reducing the temperature fluctuation range by 20-30%, improving the working efficiency and reliability of the engine.

3. Aviation cabin environment regulation

• When the cabin temperature rises to more than 15°C, the phase change material in the seat and other parts absorbs heat, making people feel cool.
• When cold outside air enters the cabin or the air conditioning system cools excessively, the phase change material releases heat to maintain a comfortable temperature in the cabin.
• In emergency situations, such as partial failure of the cabin temperature regulation system, phase change materials can also play a certain role in temperature regulation, slowing down the speed of cabin temperature change, for the pilot to gain more response time, and reduce the cabin temperature change rate by about 30-50%.
