Supplement to the Shuttle aerodynamic database using Discovery flight tests

Abstract

The Discovery vehicle was found to have longitudinal and lateral aerodynamic characteristics similar to those of the Columbia and Challenger vehicles. The lateral aerodynamic characteristics of the Columbia and Challenger vehicles are reiterated and the results from the Discovery flight test are added to this database. The longitudinal aerodynamics resulting from the analysis of flight data from all three vehicles is also shown. The values of the lateral and longitudinal parameters are compared with the preflight data book and this comparison is discussed.
