Reliable Choice Of 15℃ PCM For Military Aviation - The Elite Guard Of Military Flight Resistant To Extreme Conditions

The working principle of phase change materials:

1. When the ambient temperature is lower than 15 ° C, 15 ° C military aviation phase change materials are in solid state.
2. As the ambient temperature gradually rises, when it reaches about 15 ° C, the material begins to undergo solid-liquid phase change, from solid to liquid.
3. In this process, the material will absorb a lot of heat, storing the heat of the surrounding environment and playing a cooling role.
4. On the contrary, when the ambient temperature is reduced to less than 15 ° C, the material will gradually change from liquid to solid state, and at the same time release the previously stored heat, playing a heat preservation effect.

Characteristics of phase change materials:
1. Physical properties

• In the solid state, the material usually has a certain hardness and strength, and can withstand a certain amount of mechanical pressure and impact.
• During the flight of the aircraft, it may be subjected to mechanical stress such as vibration and turbulence, and the physical properties of the material ensure that it will not be easily damaged in this environment.
• In appearance, according to the specific application needs and processing technology, the material can be presented in different forms, such as flake, granular, block, etc., in order to facilitate installation and use in different parts of the aircraft.

2. Chemical properties

• Chemically stable, with good corrosion resistance and oxidation resistance.
• In the use of military aircraft in the environment, may be exposed to a variety of chemical substances, such as fuel, lubricating oil, hydraulic oil, etc., the chemical properties of the material to ensure that it will not react with these substances, thereby affecting its performance and service life.
• At the same time, the oxidation resistance is enough to ensure that the material will not be oxidized during long-term use.

Common application background:
When the following situations occur, the addition of phase change materials can well prevent or solve related problems.

1. Avionics temperature control

• In modern military aircraft, electronics are highly integrated and powerful, generating a lot of heat.
• At the same time, when the aircraft flies at different altitudes, the external environmental temperature changes dramatically, such as at low altitudes may be in a higher ambient temperature, and at high altitudes may face extremely low temperatures.
• These factors put forward strict requirements for the temperature stability of electronic equipment.

2. Aeronautical power system thermal management

• Power systems such as the engines of military aircraft generate extremely high heat during operation, and the performance of the engines is very sensitive to temperature.
• Excessive temperatures can lead to thermal fatigue, increased wear, and even failure of engine components.

3. Aviation cabin environment regulation

• In order to provide a comfortable working environment for the pilot, the temperature in the cockpit needs to be precisely controlled.
• At the same time, the military aircraft cabin also needs to consider the emergency temperature adjustment ability in special circumstances (such as damage to the canopy, etc.).
