This book was released on 1980 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this report is to describe an investigation conducted to develope a method for predicting the trajectory of a store separated from an aircraft flying at supersonic speeds. The aircraft model can include a circular or noncircular fuselage, engine inlets, wing, pylon, ejector rack, and circular and noncircular stores. The linear, potential flow methods used to model the aircraft components are described as are nonlinear corrections which are made to position shock waves more accurately. The methods used to calculate the nonuniform flow field, the store forces and moments, and the store trajectory are presented. Comparisons between theory and experiment for flow fields, store loading distributions, store forces and moments, and store trajectories are shown and discussed. (Author).

This book was released on 1980 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed instructions are presented for using a computer program which calculates the six-degree-of-freedom trajectories of external stores which are separated from fighter-bomber type aircraft flying at supersonic speeds. Multiple circular or elliptical store configurations may be handled. Parent aircraft configurations may consist of a circular or arbitrary cross section fuselage with ramp external compression inlets, and a wing, pylon, and rack. The program uses linear potential-flow theory to model the wing and pylon loading and thickness. Three-dimensional line sources and doublets are used to model circular fuselages and stores. The noncircular fuselage and elliptic store surfaces are modeled with constant source panels. Nonlinear corrections are made to the wing, fuselage, rack, store and fuselage inlet models to simulate shocks. The program also calculates the trajectory of the store as it separates from the aircraft. This report describes the program, presents instructions for preparing input for the program, describes the output from the program, and presents a sample case. The program represents an extension of an earlier program restricted to circular bodies at supersonic speeds written by the present authors and described in AFFDL-TR-76-41. This volume presents the instructions for preparing input for each of two programs, a sample case for each, and the descriptions of the output cases. (Author).

This book was released on 1976 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this report is to describe an investigation to develop a method for predicting the separation characteristics of a store released from a supersonic parent aircraft. The present computer program is designed to handle configurations consisting of a wing without dihedral or incidence which is attached to an axisymmetric fuselage. A pylon can be attached to the wing or under the fuselage. In this work, supersonic flow models are described to represent the configuration and special attention is given to the flow field calculation method. It is shown that the basic method utilizing linear, potential flow theory must be corrected for nonlinear effects caused by the shock from the wing leading edge. Experimental results are presented from a wind-tunnel test program designed to provide data to aid in developing and testing the theory. Comparisons between theory and experiment for flow fields, store loading distributions and store forces and moments indicate fair to very good agreement. Recommendations are given for improving the present method.
