Report of Heat Flow Thermocouple Error Analysis on 16-mm Microfilm

NSSDCA ID: PSPG-00487

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1973-01-09 to 1973-02-02

Description

This data set consists of a microfilmed report (Report on the Apollo 17 Heat Flow Experiment Thermocouple Error Investigation, B.D. Smith, Bendix Aerospace Division, ASTIR TM 30/31, December, 1973) on the Apollo 17 heat-flow thermocouple error investigation provided by the Science Requirements Branch at Johnson Space Center. Thermo-electric errors are defined by thermal models of the electronics unit and reference sensor. Temperature differentials between spurious junctions are resolved to better than 0.3 deg k. The models are verified by data acquired from environmental tests of a specially modified heat-flow experiment instrument. Apollo 15 and 17 site temperature profiles are applied to a thermal model which establishes a 0.04- deg k difference between sensors of the Apollo 17 temperature field. All errors affecting the data are summarized and error characteristics are shown for all thermocouple temperatures.
