Download or read book Full scale Wind tunnel Tests of a Small Unpowered Jet Aircraft with a T Tail written by Paul T. Soderman and published by . This book was released on 1971 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aerodynamic characteristics of a full scale executive type jet transport aircraft with a T-tail were investigated in a 40 x 80 ft (12.2 by 24.4 meter) wind tunnel (subsonic). Static, longitudinal, and lateral stability, and control characteristics were determined at angles of attack from -2 deg to 42 deg. The aircraft wing had 13 deg of sweep and an aspect ratio of 5.02. The aircraft was tested power off with various wing leading- and trailing-edge high lift devices. The basic configuration was tested with and without such components as engine nacelles, wing tip tanks, and empannage. Hinge-moment data were obtained and downwash angles in the horizontal-tail plane location were calculated. The data were obtained at Reynolds numbers of 4.1 million and 8.7 million based on mean aerodynamic chord. The model had static longitudinal stability through initial stall. Severe tail buffet occurred near the angle of attack for maximum lift. Above initial stall the aircraft had pronounced pitch-up, characteristic of T-tail configurations. A stable trim point was possible at angles of attack between 30 deg and 40 deg (depending on c.g. location and flap setting). Hinge-moment data showed no regions with adverse effects on stick force. Comparisons of wind-tunnel data and flight-test are presented.
Download or read book Flight Tests of a Leading edge Area Suction on a Fighter type Airplane with a 35 Degree Sweptback Wing written by Richard S. Bray and published by . This book was released on 1955 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests have been made to determine the flight characteristics of an F-86F airplane equipped with a leading-edge area-suction boundary-layer-control system, and to investigate the possible operational limitations imposed on a fighter-type airplane by such an installation. The results of the flight tests are compared with those of full-scale wind-tunnel tests of a similar installation on a model incorporating F-86 wing panels. The basic porous-area distribution tested extended the full length of the wing leading edge. Suction power was provided by a modified turbosupercharger which was driven by air bled from the compressor of the airplane's jet engine.
Download or read book Investigation of Slipstream Effects on a Wing inlet Oil cooler Ducting System of a Twin engine Airplane in the Ames 40 by 80 foot Wing Tunnel written by Dean R. Chapman and published by . This book was released on 1945 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of the wing-inlet oil-cooler ducts on a twin-engine airplane was conducted to determine both internal- and external-flow characteristics of the ducting installation. Tests were made with power on as well as with propellers removed. In addition, ground tests of the duct passages and model tests of various 1/2-scale revised inlets were also conducted in order to develop a ducting system with low over-all losses throughout the operating system.

Available in PDF, EPUB and Kindle. Book excerpt: The pressure-recovery characteristics at the vertical center line of an NACA submerged inlet of aspect ratio 5 have been measured in the Mach number range 0.60 to 1.08 by the wing-flow method. The variation of ram-recovery ratio determined from measurements at the center line of the inlet with test station Mach number is presented for mass-flow ratios of 0.30 to 0.60.

Available in PDF, EPUB and Kindle. Book excerpt: Results are presented on drag tests of six bodies of revolution with systematically varying shapes and with a fineness ratio of 5. The formes were derived from source-sink distributions, and formulas are presented for the calculation of the pressure distributions of the forms. The tests were made in the N.A.C.A. variable-density tunnel over a range of values of Reynolds number from about 1,500,000 to 25,000,000. The results show that the bodies with the sharper noses and tails have the lowest drag coefficients are based on the two-thirds power of the volume. The data show the most important single characteristic of the body form to be the tail angle, which must be fine to obtain low drag.

Book excerpt: A program was conducted to obtain data, both steady state and dynamic, from wind tunnel models and full scale flight tests of the RA-5C aircraft. Data were acquired on 0.228 and 0. 125 scale RA-5C inlet models and on a fully instrumented flight test RA-5C aircraft. Interim data reports presenting the data acquired during each test have been published. These data were utilized in this report to develop scaling techniques for correlating small scale model wind tunnel data with full scale flight data. Data presented include duct steady state operating characteristics and pressure distributions in the inlet and at the engine face. Dynamic data are presented in the form of engine face turbulence contour plots, radial turbulence distributions and selected spectral data functions. Data are presented for variations of angle of attack, angle of yaw, Reynolds number, ramp angle, secondary flow rates and inlet diverter width. Brief descriptions of the model and test methods are also presented.

Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted in the 8-foot high-speed wind tunnel of a 1/5-scale-model pursuit-type fuselage with a practicable internal duct arrangement designed to meet all of the air requirements of a 1000-horsepower radial engine submerged at the maximum section. Air inlet openings at the nose and outlet openings at the sides and at the tail were investigated. The internal-flow characteristics were determined and drag force pressure-distribution data obtained.
