Download or read book Aerodynamics of Guided and Unguided Weapons written by Frankie Gale Moore and published by . This book was released on 1973 with total page 218 pages. 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.

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 excerpt: New and improved version of the Naval Surface Warfare Center, Dahlgren Division aeroprediction code (AP93) has been developed. The new code contains new technology that allows planar aerodynamics of axisymmetric solid rocket-type weapons to be computed with engineering accurately over the entire Mach number range and for angles of attack to 30 deg. New technology developed and included in the AP93 includes; A new engineering method to compute aeroheating information at a high Mach number; Extension of the second-order shock-expansion theory to include real-gas effects, including several new pressure prediction techniques; An improved body-alone nonlinear normal-force method; New methods for computing nonlinear aerodynamics of wing alone, wing body, and body wing due to angle of attack, and wing body due to control deflection; and a new base-dmg database and improved empirical base-drag estimation technique. ...

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.

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.
