Operational Test of the Calspan Transient Enthalpy Probe B5M in an ARC Heated Reentry Nose Tip Test Facility

Abstract

The Calspan B5M transient enthalpy probe was evaluated in tests at the Air Force Flight Dynamics Laboratory Reentry Nose Tip Test Facility. Its survivability was excellent, melting of components did not occur as it was swept at speeds greater than 50 inches per second across the 1.1 inch diameter flow stream. Its response time was estimated as 2.1 to 3.0 milliseconds. Probe measurements made by use of averaged data were about 20% higher than the facility bulk enthalpy, but the validity of the measurements is questionable because of the sensitivity of the probe to extraneous energy inputs. These are not sufficiently defined to correct probe readings.
