Available in PDF, EPUB and Kindle. Book excerpt: The application of aeroelastic tailoring with advanced composites has made forward swept wings a viable configuration option for high performance aircraft. Forward swept wings have an inherent tendency to encounter a static aeroelastic instability called divergence. The extreme weight penalty required to avoid this instability in conventional metallic construction has been the basis for the reluctance of designers to incorporate forward sweep in aircraft. Studies performed for the Flight Dynamics Laboratory and by others independently show that, through the use of aeroelastic tailoring (the design process that makes use of the directional properties of fibrous composite materials in wing skins and orients these materials in optimum directions) with advanced composite material, the aeroelastic behavior of a conventional aft swept wing can be controlled and forward swept wings can be constructed with composites that results in an increase in the divergence speed without a prohibitive increase in weight. This report presents the background and evolution of aeroelastic tailoring as applied to forward swept wings together with a summary of work required to establish an aeroelastic data base for forward swept design.

Available in PDF, EPUB and Kindle. Book excerpt: The use of forward-swept wings has aerodynamic benefits at high angles of attack and in supersonic regimes. These consist of reduction in wave drag, profile drag, and increased high angle of attack handling qualities. These increased benefits are often offset due to an increase in structural components, to overcome flutter and wing tip divergence due to high loading of the wing tips at high angles of attack. The use of composite materials and aeroelastic tailoring of the structures eliminates these instabilities without a significant increase in weight. This work presents the design of an aeroelastic wing structure for a highly forward-swept wing, and the verification of the aerodynamic and structural finite element analysis through experimental testing.

This book was released on 1982 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principle of aeroelastic tailoring with advanced composite materials to increase the divergence speed of a forward swept wing has been demonstrated through low speed wind tunnel tests. The approach was to perform a low cost, fairly simple wind tunnel test on a variable sweep cantilever wing model. Available analytical methods were used and were shown to accurately predict the divergence speed of both aluminum and composite plate structures in the subsonic speed range. Methods were evaluated for predicting the onset of divergence using subcritical wind tunnel data. Results of the analyses and tests are presented.

Available in PDF, EPUB and Kindle. Book excerpt: This book is based on lectures held at the faculty of mechanical engineering at the Technical University of Kaiserslautern. The focus is on the central theme of societies overall aircraft requirements to specific material requirements and highlights the most important advantages and challenges of carbon fiber reinforced plastics (CFRP) compared to conventional materials. As it is fundamental to decide on the right material at the right place early on the main activities and milestones of the development and certification process and the systematic of defining clear requirements are discussed. The process of material qualification - verifying material requirements is explained in detail. All state-of-the-art composite manufacturing technologies are described, including changes and complemented by examples, and their improvement potential for future applications is discussed. Tangible case studies of high lift and wing structures emphasize the specific advantages and challenges of composite technology. Finally, latest R&D results are discussed, providing possible future solutions for key challenges such as low cost high performance materials, electrical function integration and morphing structures.

Book excerpt: In this report, laminated beam theory is used to predict the subcritical static aeroelastic behavior of swept wings constructed on laminated composite materials. Aerodynamic strip theory airloads are used to develop meaningful expressions for the flexible-to-rigid lift ratio and spanwise center of pressure movement of a swept wing as functions of wing aeroelastic parameters for a uniform property wing. A simple matrix method analysis approach to wing subcritical static aeroelastic response is detailed.

Available in PDF, EPUB and Kindle. Book excerpt: Shock-induced flow-separation ahead of trailing edge controls on swept wings is investigated with emphasis on the effects of boundary layer transition on the location and shape of the separation line. Experimental results were obtained by using forward facing steps mounted on swept-leading-edge flat-plate wing models in the ARL Mach 6 Tunnel for model running length Reynolds numbers varying from 0.9 to 33 million. The data support qualitatively a proposed, strip-type method for estimating, the extent and shape of the three dimensional region of separated flow ahead of controls on swept wings. (Author).
