This book was released on 2018-07-17 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wind tunnel data base was established for the effects of chine-like forebody strakes and Mach number on the longitudinal and lateral-directional characteristics of a generalized 55 degree cropped delta wing-fuselage-centerline vertical tail configuration. The testing was conducted in the 7- by 10-Foot Transonic Tunnel at the David Taylor Research Center at free-stream Mach numbers of 0.40 to 1.10 and Reynolds numbers based on the wing mean aerodynamic chord of 1.60 x 10(exp 6) to 2.59 x 10(exp 6). The best matrix included angles of attack from 0 degree to a maximum of 28 degree, angles of sidesip of 0, +5, and -5 degrees, and wing leading-edge flat deflection angles of 0 and 30 degrees. Key flow phenomena at subsonic and transonic conditions were identified by measuring off-body flow visualization with a laser screen technique. These phenomena included coexisting and interacting vortex flows and shock waves, vortex breakdown, vortex flow interactions with the vertical tail, and vortices induced by flow separation from the hinge line of the deflected wing flap. The flow mechanisms were correlated with the longitudinal and lateral-directional aerodynamic data trends. Erickson, Gary E. and Rogers, Lawrence W.

This book was released on 1989 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The loss of airplanes and occupants attributable to departures from controlled flight and ensuing spins has been a problem since the earliest days of aviation. These losses have plagued both the military and general aviation communities. The phenomena responsible for such losses take on added significance because, in the past ten years, high angle-of-attack capability in the post-stall region has been shown to significantly enhance the air combat maneuvering effectiveness of fighter airplanes and, therefore, this is not a region to be avoided, but rather exploited, if possible. Fortunately, the aerodynamic characteristics that produce departures and spins have been identified within the past few years through rotary balance tests, which identify an airplane's aerodynamic characteristics in a steady rotational flow environment. It was demonstrated in the Phase I that the high angle-of-attack aerodynamic characteristics are very configuration dependent and that forebody geometry can have a significant influence on these characteristics. In the extreme case, an aircraft's undesirable aerodynamics can be completely attributable to the forebody. In this instance, autorotative yawing and rolling moments, as well as increasing nose-up pitching moments with increasing rotation rate, are realized.

This book was released on 2018-07-08 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-speed wind-tunnel tests were conducted in the Langley 12-Foot Low-Speed Tunnel on a model of the Boeing Multirole Fighter (BMRF) aircraft. This single-seat, single-engine configuration was intended to be an F-16 replacement that would incorporate many of the design goals and advanced technologies of the F-22. Its mission requirements included supersonic cruise without afterburner, reduced observability, and the ability to attack both air-to-air and air-to-ground targets. So that it would be effective in all phases of air combat, the ability to maneuver at angles of attack up to and beyond maximum lift was also desired. Traditional aerodynamic yaw controls, such as rudders, are typically ineffective at these higher angles of attack because they are usually located in the wake from the wings and fuselage. For this reason, this study focused on investigating forebody-mounted controls that produces yawing moments by modifying the strong vortex flowfield being shed from the forebody at high angles of attack. Two forebody strakes were tested that varied in planform and chordwise location. Various patterns of porosity in the forebody skin were also tested that differed in their radial coverage and chordwise location. The tests were performed at a dynamic pressure of 4 lb/ft(exp 2) over an angle-of-attack range of -4 deg to 72 deg and a sideslip range of -10 deg to 10 deg. Static force data, static pressures on the surface of the forebody, and videotapes of flow-visualization using laser-illuminated smoke were obtained. Fears, Scott P. Unspecified Center...
