This book was released on 1972 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several theoretical and empirical methods are comgined into a single computer program to predict lift, drag, and center of pressure on bodies of revolution at subsonic, transonic, and supersonic Mach numbers. The body geometries can be quite general in that pointed, spherically blunt, or truncated noses are allowed as well as discontinuities in nose shape. Particular emphasis is placed on methods which yield accuracies of ninety percent or better for most configurations but yet are computationally fast. theoretical and experimental results are presented for several projectiles and a computer program listing is included an an appendix.

Available in PDF, EPUB and Kindle. Book excerpt: Several theoretical and empirical procedures are combined into a single computer program to predict lift, drag, and center of pressure on quite general wing-body geometries. The method is applicable for Mach number zero to three and angle-of-attack zero to about fifteen degrees. Computed results for several configurations compare well with experimental and other analytical results. It costs about five dollars per Mach number to compute the static aerodynamics of a typical wing-body shape on the CDC 6700 computer.

Book Synopsis The 2002 Version of the Aeroprediction Code by : Frankie Gale Moore
Download or read book The 2002 Version of the Aeroprediction Code written by Frankie Gale Moore and published by . This book was released on 2002 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 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.
Book Synopsis State-of-the-art Engineering Aeroprediction Methods with Emphasis on New Semiempirical Techniques for Predicting Nonlinear Aerodynamics on Complete Missile Configurations by : Frankie Gale Moore
Download or read book State-of-the-art Engineering Aeroprediction Methods with Emphasis on New Semiempirical Techniques for Predicting Nonlinear Aerodynamics on Complete Missile Configurations written by Frankie Gale Moore and published by . This book was released on 1993 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses the pros and cons of numerical, semiempirical and empirical aeroprediction codes and lists many state-of-the-art codes in use today. It then summarizes many of the more popular approximate analytical methods used in State-of-the-Art (SOTA) semiempirical aeroprediction codes. It also summarizes some recent new nonlinear semiempirical methods that allow more accurate calculation of static aerodynamics on complete missile configurations to higher angles of attack. Results of static aerodynamic calculations on complete missile configurations compared to wind tunnel data are shown for several configurations at various flight conditions. Calculations show the new nonlinear methods being far superior to some of the former linear technology when used at angles of attack greater than about 15 degrees.

Book Synopsis The Science of Small Arms Ballistics by : Alvah Buckmore, Jr.
Download or read book The Science of Small Arms Ballistics written by Alvah Buckmore, Jr. and published by CRC Press. This book was released on 2018-07-17 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of small arms ballistics is seriously underdeveloped and underappreciated. This unique and different book is a comprehensive study that fills a legitimate need for a work that covers the engineering and theory of small arms ballistics. The author shares his extensive research on working out the science of small arm ballistics mathematically and explains his theories, such as the field-effect and the field-effect over trajectory and time, along with new theories on interior, exterior, and terminal ballistics. Each equation describes a mathematical relationship, such as transfer of energy, and has an engineering application to help solve a design problem. Some equations, such as the calculation of bullet length with a given muzzle velocity and rate of twist, represent manipulations of those equations. Some other equations represent a set of mathematical instructions to resolve a technical problem, such as the computation of trajectory or depth of penetration of living tissue in real-time.

Book Synopsis New Methods for Predicting Nonlinear Lift, Center of Pressure, and Pitching Moment on Middile Configurations by : Frankie Gale Moore
Download or read book New Methods for Predicting Nonlinear Lift, Center of Pressure, and Pitching Moment on Middile Configurations written by Frankie Gale Moore and published by . This book was released on 1992 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new semiempirical method has been developed to predict normal force, pitching moment, and center of pressure on missile configurations up to angles of attack of 30° The method is based on linear theory and slender body techniques at low angle of attack and uses wind tunnel data to derive nonlinear angle-of-attack corrections as angle of attack increaces. The new improved theories include body alone, wing alone, and body-wing and wing-body interference. While the new theory is databased, simple analytical formulas are derived that allow general use of the techniques. Comparison with the linearized approaches used in the former NSWCDD aeroprediction code shows singificant reductions in errors of aerodynamics above 5° to 10° angle of attack. Limited comparisons to other state-of-the-art engineering codes show the new theory to be as good as or better than anything known to be available for computing planar aerodynamics up to 30° angle of attack.

Book Synopsis Estimate of Effect of MER Structural Dynamics on Store Separation by : Leroy Devan
Download or read book Estimate of Effect of MER Structural Dynamics on Store Separation written by Leroy Devan and published by . This book was released on 1974 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural flexibility has long been suspected as being a factor affecting the ejection phase dynamic response of stores. After hook opening, in-carriage loads, associated with a release store, and an ejection recoil force deflect the MER beam away from its initial position. This in turn leads to a lower ejection velocity, lower ejection pitch rate, and an induced rolling moment. A theoretical structural dynamic model is based upon "Bernoulli" pitch and yaw deflections and torsional rotation of the MER beam; wing, pylon, hanger, shoulder pad, and ejector unit deformations are neglected. Detailed development for the present report is confined to the pitch plan bending and store pitch dynamics case. For small pitch angles a linear set of kinematic and dynamic equations for the store ejection phase is obrained. Sample computations are given for two stores and constant aircraft pull-up rates. A 4-g pull-up produces the greatest structural deformations. However, the pull-up maneuver alone affects the ejection pitch rate and velocity to a greater extent than the structural deformation. A break even point occurs for small pull-up rates. For the pitch bending case, flexibiity probably accounts for no more than a 10% deviation from the rigid case. Flexibility affects the ejection angular rate more significantly.
