Designed For Harsh Military Aviation Conditions - A Thermal Storage Material That Builds A Stable Defense Line For Critical Flight Systems: 55°C Phase Change Material For Military Aviation

The working principle of phase change materials for military aviation:

• When the ambient temperature is lower than 55℃, the phase change material is solid, and the internal molecular arrangement is relatively orderly, and there is a strong interaction force between the molecules.
• As the ambient temperature gradually rises and approaches 55℃, the material molecules begin to absorb heat, and the thermal motion of the molecules gradually intensification. The absorbed heat is used to overcome the intermolecular force, prompting the molecular arrangement to gradually become loose and disordered, and then the phase transition process from solid to liquid begins.

-- Thermophysical properties
1. High latent heat

• Phase change materials absorb or release heat during the phase change process is called latent heat, 55℃ military aviation phase change materials have a high latent heat, which is the key to achieve efficient temperature control.
• The high latent heat means that under the same temperature change, the phase change material can absorb or release more heat, thus improving the effect of temperature control.

2. Appropriate specific heat capacity

• Specific heat capacity refers to the heat absorbed or released by increasing or decreasing the temperature of a substance per unit mass by 1°C.
• 55℃ military aviation phase change material has a suitable specific heat capacity, which can quickly absorb or release heat when the temperature changes, and will not cause the temperature change to be too slow because the specific heat capacity is too large, affecting the timeliness of temperature control.

3. Good thermal conductivity

• Good thermal conductivity is an important guarantee that phase change materials can quickly absorb or release heat.
• 55℃ military aviation phase change material has a high thermal conductivity, can quickly transfer heat to or from the material inside the transfer, improve the efficiency of temperature control.

-- Chemical properties
1. Chemical stability

• As mentioned earlier, phase change materials have good chemical stability and are not easy to react with other substances.
• In the field of military aviation, this can ensure that phase change materials will not be eroded by aviation fuels, lubricants, cleaning agents and other chemicals during long-term use, and maintain the stability of its performance.

2. Non-toxic and harmless

• 55℃ phase change materials for military aviation must be non-toxic and harmless, and will not cause harm to the operators and passengers of military aviation equipment.
• This is one of the basic requirements for materials in military aviation.

Product application case:
 

-- Temperature control of aero-engine components
1. Near turbocharger and combustion chamber

• In the turbocharger and combustion chamber of the aeroengine, the operating temperature is extremely high.
• 55°C military aviation phase change materials can be applied to the insulation or cooling system of these high-temperature components.
• When the component temperature rises to around 55°C, the phase change material absorbs a large amount of heat, transforming from a solid to a liquid state, preventing further heat conduction to other key components, protecting the metal structure inside the engine from high temperature damage, reducing the risk of thermal fatigue and material deformation.

2. Lubricating oil cooling system

• Engine oil will increase in temperature as it absorbs heat during operation.
• The phase change material is installed around the lubricating oil cooling pipe, when the oil temperature is close to 55°C, the material absorbs heat, assists the conventional cooling system to maintain the temperature of the lubricating oil in the appropriate range, and ensures the stable performance of the lubricating oil, so as to ensure the good lubrication and normal operation of the moving parts of the engine.

-- UAV high temperature environment application
1. Power system temperature management

• In the power system components of military drones, such as motors and battery packs, working for long periods of time generates heat.
• 55℃ military aviation phase change materials can be used for the motor shell and battery heat dissipation design, when the temperature reaches about 55℃, the material absorbs heat, prevents the motor from overheating and damage, extends the service life of the battery, and ensures the stable operation of the UAV power system, thus improving the endurance of the UAV in a high temperature environment and the task execution ability.

2. The fuselage structure is heat proof

• In some special missions (such as reconnaissance in hot areas) UAV fuselage structure may be affected by the high temperature environment.
• The phase change material is applied to the thermal insulation layer of the UAV fuselage. When the surface temperature of the fuselage rises to 55°C, the material absorbs heat, reduces the speed of heat transfer to the interior of the fuselage, and protects the internal equipment from high temperature.
