<P>PROBLEM TO BE SOLVED: To achieve measurement of physical quantity of a jet body by cold spray. <P>SOLUTION: A cold spray measuring device 10 for measuring the physical quantity of the jet body by the cold spray includes: a thermocouple 11 for detecting a temperature of the jet body; and a nose cone 15 for supporting the thermocouple 11. A half vertex angle θ1 of a top part 15A of the nose cone 15 is formed so as to be a Mach angle θ<SB POS="POST">M</SB>or less corresponding to a Mach number M when a supersonic flow of the jet body by the cold spray is represented by the Mach number M. The thermocouple 11 is mounted in the nose cone 15 and the thermocouple 11 is arranged on the top part 15A of the nose cone 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
