This book was released on 1975 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was one in a series by the Air Force Flight Dynamics Laboratory in large turret aerodynamic research. The objective of the study was the reduction of transonic drag of a particular turret configuration by the addition of area rule fairings. Wind tunnel models were tested at transonic Mach numbers from 0.6 to 0.9. An internally mounted force balance and unsteady pressure transducers were used to measure the forces and pressure variations on the model. Fairings were place beside and aft of the turret in an effort to reduce the transonic turret drag. The least drag configuration was a single fairing mounted behind the turret. This design had as much as a 55% drag reduction from the bare turret. This model also created the smallest pressure fluctuations in a circular cavity in the side of the turret.

This book was released on 1973 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind tunnel investigations of three scale models were conducted to determine the effects of model scaling in the subsonic and transonic flow regimes. The models were 4.7-, 13-, and 17-percent scale F-15 fighter equivalent body models. The data were obtained at Mach numbers from 0.60 to 1.40 and free-stream Reynolds numbers from 1.0 to 5.3 million for model angles of attack from 0 to 5 deg. The results show that at subsonic Mach numbers the zero-lift pressure drag coefficient of the basic configurations was a function of Reynolds number and Mach number. However, the pressure drag coefficient for the fuselage-alone configuration and the alternate wing configuration was essentially invariant with Mach number for Mach numbers below 0.90. The data obtained with the cylindrical afterbody model and integrated aft-end pressure drag increments show that the transonic interference resulting from model size was primarily confined to the contoured fuselage afterbody.

This book was released on 1953 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: A one-dimensional analysis of the results of the parallel-jet mixing encountered in the testing of engines in supersonic wind tunnels is reported. Equations were derived for determining the total pressure and Mach number behind the tunnel terminal shock. The method represents a simple procedure for determining these quantities while a tunnel is still in the design stage. A specific example of the method is included.

This book was released on 1947 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: Tests were conducted to determine the effects of viscosity on the drag and base pressure characteristics of various bodies of revolution at a Mach number of 1.5. The models were tested both with smooth surfaces and with roughness added to evaluate the effects of Reynolds number for both laminar and turbulent boundary layers. The principal geometric variables investigated were after-body shape and length-diameter ratio. For most models, force tests and base pressure measurements were made over a range of Reynolds numbers, based on model length, from 0.6 million to 5.0 millions. Schlieren photographs were used to analyze the effects of viscosity on flow separation and shock-wave configuration near the base and to verify the condition of the boundary layer as deduced from force tests. The results are discussed and compared with theoretical calculations.
