EQUILIBRIUM THERMODYNAMIC PROPERTIES OF HELIUM TO 60,000 K. Technical Note No. 4
Technical Report

OSTI ID:4162773
Helium was considered for use as a propellant in a plasma propulsion system because of its low molecular weight. To obtain reasonable exhauat velocities (greater than 10,000 m/sec) it is necessary to heat the gas to temperatures at which an appreciable ionization occurs. In order to assess the potentially available exhaust velocities when ionization is present, it is necessary to have a Mollier chart to determine isentropic expansions. The thermodynannic properties of helium were computed over a temperature range of 6000 to 60,000 deg K and a pressure range of 10/sup -4/ to 10/sup -2/ atm. A Mollier chart was constructed from this data. (auth)
