SUMMARY

Real thermodynamVc and transport properties of hydrogen, steam, the SSME mixture, and air are developed. The SSME mixture properties are needed for the a nalysis of the space shuttle main engine fuel turbine. The m ixture conditions for the gases, except air, are presented graphically over a temperature range from 800 to 1200 K, and a pressure range from 1 to 500 atm. A1r properties are g iven over a temperature range of 320 to 500 K, which are w ithin the bounds of the thermodynamics programs used, 1n order to p rovide mixture data which 1s more easily checked (than H2/H20) . The real gas
