Fast response surface temperature sensor for hypersonic vehicles 1

Abstract

This paper describes the design, fabrication, and evaluation technique of fast response Surface Temperature Sensor (STS). This STS was made of chromel-constantan elements with 2.2 and 0.8 mm in diameter. The calibration technique using shock tube facility for measuring the transient surface temperature and heat transfer rate is also presented. It has been proved that the STS response time is very short (less than 50 μs), and a rise time in studies of a transient surface temperature is less than 0.5 μs. © 2010 Pleiades Publishing, Ltd.
