How has high temperature affected avionics component? 


Best insight from top research papers

High temperatures have a significant impact on avionics components. The exposure to high temperatures can lead to increased ambient heat gain and prevent the rejection of waste heat, resulting in higher operating temperatures for the electronics . This can reduce the lifetime of electronic components and increase the probability of failure. To address this issue, passive thermal management techniques such as heat pipe assemblies and Loop Heat Pipes (LHP) have been developed. Heat pipe assemblies can reduce the internal temperature gradient, allowing for higher allowable sink temperatures . LHPs can transport thermal energy from alternative sinks, such as fuel, to cool the avionics enclosure . Additionally, the effect of high temperature exposure on mechanical properties has been studied, showing a decrease in fatigue life and yield strength after prolonged exposure . Therefore, high temperatures can negatively impact avionics components, but passive thermal management techniques can help mitigate these effects .

How does high temperature affect on human performence?5 answersHigh temperature has negative effects on human performance. It impairs both physical and mental productivity, including cognition, learning, and task performance. The impact of extreme temperatures on performance differs across social and economic factors. Relative humidity also plays a role, with performance being more affected by humidity under high temperature conditions. Fresh air can compensate for performance loss caused by temperature increase at high temperature. The human body adjusts to extreme temperatures to maintain a stable core body temperature, but any deviations from thermoneutral conditions can lead to decreased endurance and sports performance. In uncomfortably warm environments, individuals may need to exert more effort to maintain their performance. Overall, high temperature has detrimental effects on human performance, and these effects can be exacerbated by factors such as humidity and CO2 levels.
How does temperature affect industrial sector?3 answersTemperature has a significant impact on the industrial sector.

What are the consequences of high temperatures?5 answersHigh temperatures have various consequences. They can lead to increased mortality and hospital visits, particularly among the elderly and vulnerable groups such as low-income elderly and people with dementia. Hyperthermia can cause short-term neurological and cognitive dysfunction, especially in the central nervous system. Exposure to high temperatures can also affect the body condition of certain bird populations, leading to reduced body mass and increased mortality. In salmon, elevated water temperatures can result in disturbances in osmoregulatory homeostasis, stress responses, and premature mortality during migration. High temperatures are also associated with excess mortality and morbidity, including heat stroke, communicable diseases, cardiovascular diseases, and respiratory diseases.
What are the temperatures that a hypersonic vehicle might encounter in flight?5 answersHypersonic vehicles can encounter high temperatures during flight. The temperatures can vary depending on the flight Mach number. At Mach 5, temperatures start to increase significantly, and between Mach 4 and 6, temperatures can double. Between Mach 4 and 9, temperatures can quadruple. The extreme temperatures encountered at hypersonic velocities require the use of thermal protection systems (TPS) to protect the vehicle. The selection and sizing of the TPS are determined by the heat flux, pressure, and shear stress experienced by the vehicle. The use of Ultra-High Temperature Ceramic (UHTC) composites allows for sharper leading edges on the vehicle, as these materials can withstand temperatures as high as 3500 K.
How does high temperature impact supercapacitor?5 answersHigh temperature has a significant impact on supercapacitors. The utilization of quasi-solid conducting medium with superior interfacial properties is one approach to address the issue of leakage and stability at high temperatures. The improved charge diffusion kinetics and ion conductivity of the electrolytes at elevated temperatures result in high capacitances.
