Book Aerodynamic Characteristics Temperature and Noise Measurements of a Large scale External flow Jet augmented flap Model with Turbojet Engines Operating

Download or read book Aerodynamic Characteristics Temperature and Noise Measurements of a Large scale External flow Jet augmented flap Model with Turbojet Engines Operating written by Marvin P. Fink and published by . This book was released on 1961 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been conducted in the Langley full-scale tunnel on a large-scale model powered by turbojet engines with flattened rectangular nozzles. The wing had 35° sweep of the leading edge, an aspect ratio of 6.5, a taper ratio of 0.31, and NACA 65(1)-412 and 65-408 airfoils at the root and tip. The investigation included measurements of the longitudinal aerodynamic characteristics of the model with half-span and full-span flaps and measurements of the sound pressure and skin temperature on the portions of the lower surface of the wing immersed in the jet flow. The tests were conducted over a range or angles of attack from -8° to 16° for Reynolds numbers from 1.8 x 106 to 4.4 x 106 and a range of momentum coefficients from 0 to 2.0. In general, the aerodynamic results of this investigation made with a large-scale hot-jet model verified the results of previous investigations with small models powered by compressed-air jets. Although blowing was only done over the inboard portion of the wing, substantial amounts of induced lift were also obtained over the outboard portion of the wing. Skin temperatures were about 340° F and wing heating could be handled with available materials without cooling. Random acoustic loadings on the wing surface were high enough to indicate that fatigue failure from this source would require special consideration in the design of an external-flow jet flap system for an airplane.

Book Effect of Engine Position and High lift Devices on Aerodynamic Characteristics of an External flow Jet flap STOL Model

Download or read book Effect of Engine Position and High lift Devices on Aerodynamic Characteristics of an External flow Jet flap STOL Model written by Charles C. Smith (Jr.) and published by . This book was released on 1971 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been conducted to provide some basic information on the aerodynamic design parameters of an external-flow jet-flap configuration. Included in the investigation were static Porce tests to determine the effects of engine vertical and longitudinal position, jet-exhaust deflectors, flap size and type, leading-edge slat chord and deflection, and gap and overlap of the slats and flaps. The force tests were made in the Langley full-scale tunnel with a model having an unswept untapered wing and powered by four simulated high-bypass-ratio turbofan engines.
