A Thermocouple Subcarrier Oscillator for Telemetering Temperatures From Pilotless Aircraft

Description: Note presenting a subcarrier oscillator which, in conjuncting with a telemetering system, gives a satisfactory method for telemetering temperatures by means of thermocouples from pilotless aircraft. The method results in an oscillator having a small size, low microphonics, high input resistance, and satisfactory stability if a switch is used to commutate calibration voltages along with the pickups.

Experimental Study of Heat Transfer to Small Cylinders in a Subsonic, High-Temperature Gas Stream

Description: A Nusselt-Reynolds number relation for cylindrical thermocouple wires in crossflow was obtained from the experimental determination of time constants. Tests were conducted in exhaust gas over a temperature range of 2000 to 3400 R, a Mach number range of 0.3 to 0.8, and a static-pressure range from 2/3 to 1-1/3 atmospheres, yielding a Reynolds number range of 450 to 3000. The correlation obtained is Nu=(0.428 plus or minus 0.003) times the square root of Re* with average deviations of a single o… more

NUCLEAR BATTERY-THERMOCOUPLE TYPE THIRD QUARTERLY REPORT for JULY 1, 1957 TO SEPTEMBER 30, 1957

Description: A second thermoelectric generator consisting of unitized rings of thermopiles was designed and constructed. Three and four rings were asserabled into generators and tested. A maximum efficiency of 0.67% was obtained. At a DELTA T of 400 deg C, an efficienty of 0.56% was obtained; the theoretical maximum for the materials used is 0.83%. (auth)

NUCLEAR BATTERY--THERMOCOUPLE TYPE. Quarterly Report No. 1 for January 1, 1957-March 31, 1957

Description: The potential usefulness as a heat source for the thermal battery of 1300 radioactive isotopes was investigated. All but thirty-two have been eliminated because of too long or too short a half-life and/or excessive gamma radiation of the isotope or element. Further eliminations are being made on the basis of relative availability and costs. (auth)
