This book was released on 1975 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of active control technology to suppress flutter has been demonstrated successfully in the Langley transonic dynamics tunnel with a delta-wing model. The model was a simplified version of a proposed supersonic transport wing design. An active flutter-suppression method based on an aerodynamic energy criterion has been verified by using three different control laws. The first two control laws utilized both leading-edge and trailing-edge active control surfaces, whereas the third control law required only a single trailing-edge active control surface. At a Mach number of 0.9 the experimental results demonstrated increases in the flutter dynamic pressure from 12.5 percent to 30 percent with active controls. Analytical methods were developed to predict both open-loop and closed-loop stability, and the results agreed reasonably well with the experimental results.

Download or read book Active Control Systems for Load Allevation Flutter Suppression and Ride Control written by ADVISORY GROUP FOR AEROSPACE RESEARCH AND DEVELOPMENT PARIS (France) and published by . This book was released on 1974 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of the ever increasing performance of modern aircraft, wing safety must be improved, without any weight penalty, through devices permitting the suppression of critical flutter speeds, on the one hand, and, on the other, the alleviation of maneuver or gust induced loads. Such devices are always active systems based on the feed-back principle. The present AGARDograph collect, in a single volume, several papers on this theme presented on the occasion of a specialists' meeting organized in The Hague in October 1973 under the joint sponsorship of two separate working groups of the AGARD Structures and Materials Panel: one of these groups deals with the interactions and maneuverability of aircraft in flight, the other with aeroelasticity and unsteady aerodynamics.

Available in PDF, EPUB and Kindle. Book excerpt: Recent development of a smart structures module and its successful integration with a multidisciplinary design optimization software ASTROS* and an Aeroservoelasticity (ASE) module is presented. Application examples have been worked out to demonstrate the integrated software capability. These include the neural net based active flutter suppression of a modeled F-16 wing using piezoelectric(PZT) actuators the gust-load alleviation of a modeled F-l8 aircraft using control surfaces and trim drag reduction of TOMAHAWK with/without battle damage using PZT actuators.
