摘要: Different types of Large Carbon Cluster (LCC) layers are synthesized by a single-step pyrolysis technique at various ratios precursor mixture. The aim is to develop fast responsive and stable thermal gauge based on LCC layer which has relatively good electrical conduction in order use it the hypersonic flow field. thermoelectric property been studied. It found that these carbon clusters sensitive temperature changes. Therefore suitable gauges were developed for blunt cone bodies tested shock tunnels Mach number 6.8 measure aerodynamic heating. this encounters high shear forces hostile environment test duration range millisecond. results favorable large as better sensor than conventional platinum thin film view responsiveness stability.
