Book excerpt: The use of canards in advanced aircraft for control and improved aerodynamic performance is a topic of continued interest and research. In addition to providing maneuver control and trim, the influence of canards on wing aerodynamics can often result in increased maximum lift and decreased trim drag. In many canard-configured aircraft, the main benefits of canards are realized during maneuver or other dynamic conditions. Therefore, the detailed study and understanding of canards requires the accurate prediction of the non-linear unsteady aerodynamics of such configurations. For close-coupled canards, the unsteady aerodynamic performance associated with the canard-wing interaction is of particular interest. The presence of a canard in close proximity to the wing results in a highly coupled canard-wing aerodynamic flowfield which can include downwash/upwash effects, vortex-vortex interactions and vortex-surface interactions. For unsteady conditions, these complexities of the canard-wing flowfield are further increased. The development and integration of advanced computational technologies provide for the time-accurate Navier-Stokes simulations of the steady and unsteady canard-wing-body flox, fields. Simulation, are performed for non-linear flight regimes at transonic Mach numbers and for a wide range of angles of attack. For the static configurations, the effects of canard positioning and fixed deflection angles on aerodynamic performance and canard-wing vortex interaction are considered. For non-static configurations, the analyses of the canard-wing body flowfield includes the unsteady aerodynamics associated with pitch-up ramp and pitch oscillatory motions of the entire geometry. The unsteady flowfield associated with moving canards which are typically used as primary control surfaces are considered as well. The steady and unsteady effects of the canard on surface pressure integrated forces and moments, and canard-wing vortex interaction are presented in detail incl..

Book excerpt: The largest weapons development effort ever undertaken by the State of Israel, the Lavi fighter program envisioned a new generation of high-performance aircraft. Controversially, Israel Aircraft Industries intended to develop and manufacture the fighters in Israel with U.S. financial support. The sophisticated planes, developed in the mid-1980s, were unique in design and intended to make up the majority of the Israeli Air Force. Though a great deal of prestige and money was staked, developmental costs increased and doubts arose as to whether the Lavi could be the warplane it was meant to be. Eventually, the program became a microcosm for the US-Israel relationship and of Israeli society itself--a study in the ambitions, fears, and internal divisions that shaped them. The fighter never made it to operational service. Despite the passage of time since its cancelation, the Lavi remains a controversial subject within Israeli society to this day. Until now, the full breadth and significance of the Lavi story has never been told. "Lavi: Israel's Lost Winged Lion" traces the evolution of the Lavi fighter from its genesis in the 1970s to its demise in August of 1987. Painting the era's political landscape on both sides of the ocean, author John Golan examines the roles of such Israeli military icons and political leaders as Ezer Weizman, Ariel Sharon, Menachem Begin, and Yitzhak Rabin. On the American side, Golan traces the evolution of U.S. government policy towards the program, detailing a complex, nuanced picture of the U.S. foreign policy apparatus and of U.S.-Israel relations in general--from President Reagan's public endorsement of the program on the White House lawn to Defense Secretary Caspar Weinberger's unremitting attempts to cancel the program in succeeding years.

Carlson and published by . This book was released on 1955 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: An experimental investigation has been performed to determine the effect of changes in body cross-section shape on the aerodynamic characteristics of bodies and wing-body combinations. A series of 13 bodies having a given length and given longitudinal distribution of cross-sectional area but various cross-section shapes were tested at a Mach number of 2.01. The bodies were tested alone and in combination with a 47° sweptback wing having a 6-percent-thick hexagonal section.
