Analysis of efficiency characteristics of a single-stage turbine with downstream stators in terms of work and speed requirements

Analysis of efficiency characteristics of a single-stage turbine with downstream stators in terms of work and speed requirements

Date: January 23, 1957
Creator: Wintucky, William T & Stewart, Warner L
Description: One-dimensional mean-section flow and blade specific losses proportional to average specific kinetic energy are assumed in the analysis. Range of the work-speed parameter lambda considered includes low to moderate blade speeds with high specific work outputs, where critical turbojet, turbopump, and accessory-drive turbines are encountered. A diffusion factor of 0.5 limits the loading on the downstream stators. Turbine efficiences considered are total or aerodynamic, rating, and static. Efficiences of velocity-diagram types at impulse and that corresponding to values of maximum efficiency are presented and compared to indicate in what range of lambda downstream stators are beneficial as well as the attending improvements in efficiency.

Analysis of fluorine addition to the vanguard first stage

Analysis of fluorine addition to the vanguard first stage

Date: January 24, 1957
Creator: Tomazic, William A; Schmidt, Harold W & Tischler, Adelbert O
Description: The effect of adding fluorine to the Vanguard first-stage oxidant was anlyzed. An increase in specific impulse of 5.74 percent may be obtained with 30 percent fluorine. This increase, coupled with increased mass ratio due to greater oxidant density, gave up to 24.6-percent increase in first-stage burnout energy with 30 percent fluorine added. However, a change in tank configuration is required to accommodate the higher oxidant-fuel ratio necessary for peak specific impulse with fluorine addition.
