People traveling in the sky, goods transported in the air, which is the epitome of the future of low-altitude economy, the development of large cities are increasingly limited by the ground environment space, and exploring and extending into the airspace is becoming a development trend. However, in order for these vehicles to fly safely and reliably in the sky, environmental simulation testing is indispensable. Sanwood Technology is committed to providing high-precision environmental test solutions for low-altitude vehicles such as UAVs and eVTOLs, Our Thermal Shock Test Chamber can help enterprises to improve product reliability and accelerate airworthiness certification.
Product Impacts under Dramatic Temperature Changes
Low altitude products can face severe environmental challenges under conditions of rapid temperature change, which may have a significant impact on their structure, materials, electronics, and overall performance. The main effects and typical failure modes are analyzed below:
1.Influence of structure and materials
Thermal expansion and contraction effect: Different materials (e.g. metals, composites, seals) have different expansion coefficients, and rapid temperature change will lead to uneven stress within the structure, triggering deformation, micro-cracks or delamination.
2. Impact on avionics and onboard equipment
Failure of electronic components
Solder joint breakage: PCBs crack at solder joints due to thermal mismatch of materials.
Component performance drift: sensor calibration parameters shift due to temperature change, affecting flight control accuracy.
3. Impact on power system
Thermal shock of turbine blades: when the engine drops from high to low temperature, the metal blades are prone to microscopic cracks.
Standard Requirement
GJB 150.5A is an environmental test standard in China's national military standard, which is called “Environmental Test Methods for Military Equipment Laboratory Part 5: Temperature Shock Test”. This standard is part of GJB 150 series, which mainly focuses on testing the adaptability and reliability of military equipment under the environment of rapid temperature changes, evaluating the equipment's ability to withstand drastic changes in temperature, and detecting potential failures of materials, structures or components due to thermal expansion and contraction.
