This book was released on 1974 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical investigation was made to develop methods for predicting the longitudinal aerodynamic characteristics of externally-blown, jet-augmented wing-flap combinations. A potential flow analysis was used to develop two models: a wing-flap lifting surface model and a high-bypass-ratio turbofan engine wake model. Use of these two models in sequence provides for calculation of the wing-flap load distribution including the influence of the engine wake. The method can accommodate multiple engines per wing panel and part-span flaps but is limited to the case where the flow and geometry of the configuration are symmetric about a vertical plane containing the wing root chord. Comparisons of predicted and measured lift and pitching moment on unswept and swept wings with one and two engines per panel and with various flap deflection angles indicate satisfactory prediction of lift and moment for flap deflections up to 30 to 40 degrees. At higher flap angles with and without power, the method begins to overpredict lift, due probably to the appearance of flow separation on the flaps.

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.

Book excerpt: The state of the art of STOL aerodynamic technology for selected lift/propulsion concepts was surveyed to identify the available test data and prediction methods in the literature. The report consists of two volumes. In Volume I important areas of technology and information necessary for the evaluation of STOL aircraft aerodynamics are listed; the aerodynamic test data and prediction methodology relevant to the deflected slipstream and externally blown flap concepts are assessed, with emphasis on the latter; an empirical method for the prediction of the longitudinal aerodynamic characteristics of externally blown flap configurations is presented; and high-lift technology for five lift/propulsion concepts is assessed in application to a medium-sized STOL transport.
