Schemensky and published by . This book was released on 1973 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents the methods, equations, and substantiating data for an empirically based computer program for the rapid and accurate evaluation of the aerodynamic characteristics of large aircraft (bombers, tankers, and transports) from takeoff through landing and through the subsonic, transonic, and supersonic speed regimes. The program calculates lift, moment, and drag characteristics at both low- and high-lift conditions, including the effects of ground proximity during landing and takeoff. The input requires the configuration geometry and the aerodynamic conditions for which solutions are desired. The program includes the capability of analyzing both fixed-wing and variable-sweep-wing configurations as well as the aerodynamic characteristics of the most recent supercritical wing designs.

Book excerpt: The report (Volume II, Program User Guide) describes the computer program developed for the evaluation of the aerodynamic characteristics of large aircraft (bombers, tankers, and transports). The program calculates lift, moment, and drag characteristics of aircraft through the subsonic, transonic, and supersonic speed regimes, and includes the capability of calculating the effect of high-lift systems in both free air and in ground effect for landing and takeoff. The input to the computer program requires the configuration geometry and the aerodynamic conditions for which solutions are desired. The program includes the capability of analyzing both fixed-wing and variable-sweep- wing configurations as well as the aerodynamic characteristics of supercritical wing designs.

This book was released on 2019-07-23 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces a stability and control methodology named AeroMech, capable of sizing the primary control effectors of fixed wing subsonic to hypersonic designs of conventional and unconventional configuration layout. Control power demands are harmonized with static-, dynamic-, and maneuver stability requirements, while taking the six-degree-of-freedom trim state into account. The stability and control analysis solves the static- and dynamic equations of motion combined with non-linear vortex lattice aerodynamics for analysis. The true complexity of addressing subsonic to hypersonic vehicle stability and control during the conceptual design phase is hidden in the objective to develop a generic (vehicle configuration independent) methodology concept. The inclusion of geometrically asymmetric aircraft layouts, in addition to the reasonably well-known symmetric aircraft types, contributes significantly to the overall technical complexity and level of abstraction. The first three chapters describe the preparatory work invested along with the research strategy devised, thereby placing strong emphasis on systematic and thorough knowledge utilization. The engineering-scientific method itself is derived throughout the second half of the book. This book offers a unique aerospace vehicle configuration independent (generic) methodology and mathematical algorithm. The approach satisfies the initial technical quest: How to develop a ‘configuration stability & control’ methodology module for an advanced multi-disciplinary aerospace vehicle design synthesis environment that permits consistent aerospace vehicle design evaluations?

This book was released on 1973 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume describes engineering methods for the prediction of the aerodynamic and stability and control characteristics of STOL aircraft employing internally ducted jet flaps, externally blown jet flaps, and mechanical flap systems with vectored thrust. These methods are intended to be used in conjunction with the theoretical methods and the associated computer program (STOL Aerodynamic Methods Computer Program) discussed in Volumes I and II, respectively. These engineering methods are intended to provide a rational approach for the aerodynamic analysis of complete STOL aircraft configurations and to provide semi-empirical methods to account for those effects not treated by the theoretical methods. These methods have been applied to configurations representative of each of the powered high-lift concepts, and the results of these analyses have been presented along with available experimental data to indicate the validity and range of applicability of the methods.

This book was released on 1973 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes the STOL Aerodynamic Methods Computer Program, which is intended to aid the engineer in the design and analysis of STOL aircraft employing internally ducted jet flaps, externally blown jet flaps, and mechanical flap systems with vectored thrust. The program provides capabilities to predict either the overall aerodynamic characteristics of a configuration or the aerodynamics of the following: Jet-wing (in or out of ground effect); wing and vectored jets; fuselage in the flow field of the jet-wing and/or vectored jets; empennage in the flow field of the jet-wing and/or vectored jets. The program includes the capabilities for investigating the effects of arbitray wing planforms with arbitrary high lift systems, including partial span flaps, slats, and jets; arbitrary camber, twist, and jet deflection; fuselages with arbitrary cross-sections and upsweep; arbitrary empennage arrangements, including conventional tails, mid-tails, and T-tails; and a capability to calculate the off-body flow field induced by the jet-wing and/or vectored at arbitrary points.
