High-fidelity Structural Optimization of a Tow-Steered Composite Wing
1. Abstract Composite materials are now making their way into the primary structures of large transport aircraft and have contributed to more efficient airframes. However, the composites used so far consist in conventional plies with fixed angles. The introduction of the capability to manufacture tow-steered composites opens the door to more efficient airframes by enabling more tailored structu...
متن کاملHigh-fidelity Aerostructural Optimization of a High Aspect Ratio Tow-steered Composite Wing
In the last 30 years since their introduction into aerospace applications, composites have become increasingly used, making up as much as 50% of modern aircraft by weight. Considering this fact, it is surprising that most aircraft today are only scratching the surface of the true potential of composite technology with traditional uniaxial fibers. With the introduction of Automated Fiber Placeme...
متن کاملHigh-fidelity Multipoint Aerostructural Optimization of a High Aspect Ratio Tow-steered Composite Wing
Composite materials have been playing a major role in modern aircraft design due to their high stiffness and strength to weight ratio. While the advantages of composite structures over their metallic counterparts is significant, it is possible to improve even further on the benefits offered by traditional composites through the use of novel composite manufacturing methods. One such method is au...
متن کاملAeroelastic Tailoring of Composite Box Beams
Aeroelastic instabilities are an important factor in the design of modern high-speed, flexible aircraft. The current trend is toward the creative use of composites to delay these instabilities. To obtain an optimum design, an accurate as well as efficient model is required. As a first step towards this goal, aeroelastic analysis is carried out for a swept composite box beam, using a linear stru...
متن کاملAeroelastic Tailoring of the NASA Common Research Model via Novel Material and Structural Configurations
This work explores the use of tow steered composite laminates, functionally graded metals (FGM), thickness distributions, and curvilinear rib/spar/stringer topologies for aeroelastic tailoring. Parameterized models of the Common Research Model (CRM) wing box have been developed for passive aeroelastic tailoring trade studies. Metrics of interest include the wing weight, the onset of dynamic flu...
