Optically Transparent Flexible Broadband Metamaterial Absorber Based on Topology Optimization Design
A conformal metamaterial absorber with simultaneous optical transparency and broadband absorption is proposed in this paper. The absorptance above 90% over a wide frequency range of 5.3–15 GHz can be achieved through topology optimization combined with a

Thermal Analysis of Polyamide 6 Composites Filled by Natural Fiber Blend
This study describes changes in the viscoelastic and thermal properties of composites made with various percentages (up to 20 wt.%) of a natural fiber blend (a mixture of flax, kenaf, and hemp fibers) and polyamide 6 (PA 6). According to the differential

Review of Adaptive Shock Control Systems
Drag reduction plays a major role in future aircraft design in order to lower emissions in aviation. In transonic flight, the transonic shock induces wave drag and thus increases the overall aircraft drag and hence emissions.

An improved method of using equilibrium profile to design radial tires
Tire performances are strongly influenced by cross section profile, and equilibrium profile has been a focus of radial tire researches, however, how to use the profiles to design radial tires has been reported rarely due to reasons of secrecy. This paper

Validation of a 20 m Wind Turbine Blade Model
In the projects Smartblades and Smartblades 2 a full-scale 20 m rotor blade for the NREL CART3 wind turbine was designed, built and tested. The rotor blade was intended to have a strong bending–torsion coupling. By means of the experiments, the proof for
