Abstract: The present disclosure provides a wind turbine blade with an improved trailing edge structure and a manufacturing method thereof. The wind turbine blade includes an upper shell, a lower shell, and a trailing edge, where a trailing edge bonding region enclosed by the upper shell, the lower shell and the trailing edge is filled with composite materials, and the composite materials are discontinuous in an airfoil chordwise direction. The manufacturing method includes the following steps: S1: manufacturing reinforcements with a same cross-sectional shape as the trailing edge filling region for composite materials; and S2: integrally molding the reinforcements, a fiber fabric and the upper shell, providing the lower shell, combining the upper shell and the lower shell, and performing heating for curing and molding. The discontinuous filling structure reduces usages of the adhesive and the reinforcements of the composite materials.

Abstract: The present disclosure provides a lightweight spar cap with a concave structure for a wind turbine blade and a manufacturing method thereof, a wind turbine blade and a manufacturing method thereof. The lightweight spar cap is groove-shaped as a whole, and includes supporting portions located on two wings of the lightweight spar cap and an intermediate connecting portion connecting the two supporting portions. The manufacturing method of the lightweight spar cap includes laying a reinforcing body of the intermediate connecting portion and a supporting material of the supporting portion, and performing resin infusion. By comprehensively considering multiple factors, the present disclosure reduces the weight of the wind turbine blade, improves the material utilization of the wind turbine blade, and realizes a lightweight wind turbine blade.

Abstract: A large-size wind power blade with a multi-beam structure and its manufacturing method, wherein the blade adopts a hollow layout structure and comprises a blade skin suction edge, a blade skin pressure edge, a main load-carrying structure crossbeam and anti-shearing webs, wherein the blade skin suction edge and the blade skin pressure edge are combined to form a cavity structure having a streamlined cross section, wherein a support structure formed by the combination of the main load-carrying structure crossbeam and the anti-shearing web is located in the cavity. Both the blade skin suction edge and the blade skin pressure edge adopt a multi-segment combined structure, wherein the multiple segments are connected to the side surface of the main load-carrying structure crossbeam to integrally form the blade skin suction edge and the skin pressure edge.

Abstract: Systems and methods for managing profiles and performing translations, validating translations, and managing student profiles are disclosed. An exemplary method includes receiving a registration request, providing a registration interface to a user device, receiving an expertise area selection and a user identifier from the user device, converting the expertise area selection from a base language to a target language, sorting users by expertise area into a list, and transmitting the list in the target language to a target user. A translation method includes receiving a sentence in a base language, accessing a translation system, generating and comparing a plurality of translations in a target language, and returning a satisfactory translation.

Abstract: The present invention utilizes a message which can be sent from any suitable source for an appropriate message. The basic message includes a pin number, the desired telephone from which the caller intends to talk. This caller may intend his own cell-phone or another's cell phone or any other telephone to be the originating telephone. Included in the message is the destination telephone number. The message is sent to a service center which verifies the pin number and sets up to charge the pin associated pre-paid or open account. Upon verification, a switch is set with the destination telephone number in its switch calling memory. Upon setting up the switch for the call, a call is placed to the intended originating telephone. When that telephone is answered, the destination telephone number is called. The basic message may be an SMS, an e-mail or sent from a web-site which is provided for the service center. In the future, additional suitable sources may also available.
