DOWNLOAD EBOOKA new version of the aeroprediction code (APC), the AP02, has been developed to address the requirements arising from advanced weapon concepts. The AP02 was formed by adding significant new technology and several productivity improvements to the previous version of the APC, the AP98. New technology added included 6 and 8 fin aerodynamics, improved nonlinear aerodynamics, improved pitch damping predictions, improved power-on base drag estimates, base-bleed effect on base drag estimation, improved axial force of nonaxisymmetric bodies and trailing-edge flap capability. Other improvements and productivity enhancements include an aerodynamic smoother, ballistic and three degree-of-freedom simulation modules as well as refinements for the pre- and post-processor for inputs and outputs of the AP02. Comparison of the predicted aerodynamics of the AP02 to AP98 and experimental data showed the AP02 to be slightly better than the AP98 in most cases that both codes would handle. However, due to the additional new technology incorporated into the AP02, many new options are available in the AP02 that are not available in the AP98. Therefore, the AP02 is more robust and, on average, is slightly more accurate than the AP98 in predicting aerodynamics of weapons.

DOWNLOAD EBOOKA cooperative experimental investigation has been performed to obtain a systematic fin-body and fin-plate database for series of 12 missile fins. These data are intended to complement and extend the information contained in the Triservice missile project and to provide a systematic set of experimental data from which fin-body interference factors can be derived. Data were obtained with the fins mounted on both an axisymmetric body and on a flat plate that was used to simulate fin-alone measurements. The experiments were conducted at Mach numbers from 0.60 to 3.95; fin deflection angles of 0°, 10° , and -10° ; and angles of attack up to 30° on the body and up to 95° on the flat plate. The data were obtained from three-component balances attached to the fins and a six-component balance located in the axisymmetric body. The data obtained in this project are documented in tabular form in this report. In addition, selected data are presented in graphical form to illustrate the effects of the test variables.

DOWNLOAD EBOOKMoore brings 30 years of experience in weapons development to help bridge the gap between the academic textbook and practical application. The book reviews all approaches to calculate aerodynamics, allowing engineers to see the pros and cons of each approach, setting the stage for a semiempirical approach. It contains many approximate aerodynamic methods, bringing together in a single text both linearized and nonlinear aerodynamic methods. Practicing engineers will value the books emphasis on understanding the physics involved, understanding the assumptions made to get to the approximate approaches, and showing final equations used in the solution process.
