Free-To-Roll Analysis of Abrupt Wing Stall on Military Aircraft at Transonic Speeds
LE leading edge Transonic free-to-roll and static wind tunnel tests for four military aircraft – the AV-8B, the F/A-18C, the pre-production F/A-18E, and the F-16C – have been analyzed. These tests were conducted in the NASA Langley 16-Foot Transonic Tunnel as a part of the NASA/Navy/Air Force Abrupt Wing Stall Program. The objectives were to evaluate the utility of the freeto-roll test techniqu...
متن کاملObliique-Wing Aircraft
The application of the eigensystem synthesis technique to place the closed-loop eigenvalues and shape the closed-loop eigenvectors has not been practical for active flutter suppression, primarily because of the availability of only one control surface (aileron) for flutter suppression. The oblique-wing aircraft, because of its configuration, provides two independent surfaces (left and right ail...
متن کاملTransonic Wing Design by Inverse Optimization Using Moga
An inverse optimization method coupled with a multiobjective Genetic Algorithm has been applied to design a transonic wing for mid-size regional aircraft. Optimization of target pressure distributions was formulated to give minimum induced drag as well as minimum profile drag. The straight isobar pattern of pressure contours was specified on the upper surface of the wing. To design a realistic ...
متن کاملMultidisciplinary Design Optimization of Aircraft Wing Planform Based on Evolutionary Algorithms
This paper examines the evolutionary approach for aircraft design optimization. Several niching and elitist models are first applied to Multiple-Objective Genetic Algorithms (MOGAs). Numerical results suggest that the combination of the fitness sharing and the best-N selection leads to the best performance. The resulting MOGA is then applied to multidisciplinary design optimization problems of ...
متن کاملTransonic Free-To-Roll Analysis of the F/A-18E and F-35 Configurations
The free-to-roll technique is used as a tool for predicting areas of uncommanded lateral motions. Recently, the NASA/Navy/Air Force Abrupt Wing Stall Program extended the use of this technique to the transonic speed regime. Using this technique, this paper evaluates various wing configurations on the pre-production F/A-18E aircraft and the Joint Strike Fighter (F-35) aircraft. The configuration...
