Improvements to Power-On Base Pressure Prediction for the Aeroprediction Code

摘要

New technology has been developed and added to the power-on base drag prediction model in the aeroprediction code. The new technology showed improvement over the January 2009 release of the code compared with experiment for all cases considered. Of particular note is the capability to predict base pressure for power-off conditions and at all values of power-on including base bleed and values of thrust coefficient below where the minimum value of power-on base pressure occurs. To the authors' knowledge, this is the first theoretical method available to predict power-on base pressure at any value of thrust coefficient.
