    摘要： A rotor blade assembly for a wind turbine is disclosed. The rotor blade assembly includes a rotor blade having surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending between a tip and a root. The rotor blade assembly further includes a noise reducer mounted to a surface of the rotor blade, the noise reducer comprising a plurality of noise reduction features. The rotor blade assembly further includes a bond layer disposed between the noise reducer and the rotor blade for bonding the noise reducer to the rotor blade, the bond layer having a shear modulus approximately equal to or less than 500 megapascals.

    摘要： A light-weight, high-strength composite pin for use in pin-jointed reciprocating mechanisms and a method of preparation thereof is provided. Basically, the pin has a tubular metal sleeve and an interior fiber-reinforced resin core. At least 50% of the fibers in the core are continuous fibers which are oriented at a predetermined specific angle of orientation ranging, in general, from 0.degree. to about .+-.25.degree.. Indeed, in a preferred embodiment of the present invention, the fibers are cross-plied at an angle of orientation of from about 5.degree. to about 12.degree..

    摘要： A composite piston for internal combustion engines is provided. The base structure of the piston is formed from a fiber-reinforced resin material. Covering the head portion of the base structure and integral therewith is a cap portion formed of a nonflammable material such as metal, metal alloys and ceramics. The cap and head portion of the piston have an outer diameter which is less than the outer diameter of the piston body by an amount sufficient to accommodate for the difference in the thermal coefficient of expansion of the material of the cap and the material of the base structure.

    摘要： The transducers are incorporated in or laminated to wind blades and electrically connected to a self-powered electrical circuit. The transducers in combination with the self-powered electrical circuit improve the wind blades' response to changing wind conditions by reducing loads, at least until the turbines pitch axis system can alter the lie of the blades. Thus, when there is a change in wind conditions, the resultant twisting or bending of the wind blade during the impact of the wind (gust) on the wind blade is used to extract energy from the transducers. This energy is then transferred to the electrical circuit which in turn sends a signal back to the transducers to actuate them so as to resist the imposed load.
