Integrating Cutting-Edge Technology And Demonstrating Excellent
Phase Change Properties - The Shining Star Driving The Innovation
Of Military Aviation Temperature Control: 25°C Military Aviation
PCM
Product introduction:
- The latent heat of phase transition of military aviation phase
change materials is usually high, which means that a large amount
of heat can be absorbed or released during the phase change
process.
- It plays a key role in temperature control, energy storage and
release of military aviation equipment, and provides strong support
for ensuring the efficient, stable and safe operation of military
aviation equipment.
Advantages:
1. High energy storage density
- Phase change materials can absorb or release a lot of heat during
the phase change process, and 25 °C military aviation phase change
materials can store more energy in a relatively small volume.
- This is very important for military aircraft with limited space,
which can effectively reduce the weight and volume of equipment,
improve the load capacity and fuel efficiency of the aircraft.
2. Precise temperature control
- The material undergoes a phase transition at around 25 °C and is
able to effectively absorb or release heat near this temperature
point, thereby keeping the ambient temperature relatively stable.
- In military aircraft, this is essential for the proper operation of
temperature-sensitive components such as electronics, instruments
and instruments to prevent equipment failure or performance
degradation due to too high or too low temperatures.
3. High reliability
- After rigorous screening and testing, it has good chemical
stability and thermal stability, and can work stably in complex
aviation environments for a long time.
- For example, including high temperature, low temperature, high
altitude, strong vibration and other harsh conditions to ensure the
safe flight of aircraft.
4. Reusable
- The phase change process is reversible, the material can
continuously absorb and release heat in the process of temperature
change, repeated use without performance attenuation, reducing the
cost of use and maintenance difficulty.
Product application scenarios:
1. Avionics bay
- By keeping the temperature around the device stable, the material
can effectively extend the service life of electronic devices.
- For example, in the electronic equipment bay of some
high-performance fighter aircraft, the mean time to failure (MTBF)
of the electronic equipment can be improved by about 30% to 50%
after the use of phase change materials, significantly improving
the reliability and combat effectiveness of the avionics system.
2. Aircraft fuel system
- The temperature of aircraft fuel has a great influence on the
fluidity and combustion performance of the fuel.
- During flight, fuel temperature may fluctuate due to thermal
radiation from the engine, changes in ambient temperature and other
factors.
- The phase change material is installed on the inner wall of the
fuel tank or around the fuel pipeline, when the fuel temperature is
close to 25 °C and has a rising trend, the material absorbs heat,
prevents the fuel temperature from being too high, and avoids the
increase of fuel evaporation loss and the occurrence of unstable
combustion.
- When the fuel temperature drops, the phase change material releases
heat to maintain the fuel temperature within a suitable range,
ensuring that the fuel can be normally supplied and burned.
3. Aviation cabin environment regulation
- In some emergency situations, such as when the cabin air
conditioning system partially fails, phase change materials can
play an emergency temperature regulation role, release heat to
maintain the temperature in the cabin within a certain period of
time to maintain the appropriate range, for the pilot to gain more
response time, to ensure flight safety.
4. Helicopter blade anti-icing deicing
- Helicopter blades tend to freeze when flying in cold weather or at
high altitudes.
- A heating channel containing 25℃ phase change material is designed
inside the blade or an anti-icing coating containing phase change
material is coated on the surface of the blade.
- When the blade temperature is below 25 °C and there are signs of
icing, the phase change material is transformed by heating or using
external heat, and the heat released can prevent the formation of
ice or melt the ice that has been formed.
5. Uav thermal management
- By stabilizing the device temperature, battery performance
deteriorates and device power consumption increases due to
overtemperature.
- Phase change materials can extend the endurance of the UAV to a
certain extent. In the application tests of some small
reconnaissance drones, the endurance time of the drones can be
extended by about 10%-20% after the use of phase change materials.
