Problems solved by technology

Therefore, an increase in the number of formed tower lengths results in an increase in manufacturing costs, transportation costs and on-site assembly costs
[0006] Therefore, there is a need in the art to provide a wind turbine tower that provides on-site fabrication to address the increasing transport difficulties that arise with larger diameter tower sections

Embodiment Construction

[0032] The present disclosure will be described in connection with certain embodiments for the purpose of illustration only; however, it will be understood that other objects and advantages of the present disclosure will be apparent from the following description in light of the accompanying drawings of the present disclosure. While preferred embodiments are disclosed, they are not intended to be limiting. Rather, the general principles set forth herein are to be considered as illustrative of the scope of the disclosure only, and it will be further understood that many changes may be made without departing from the scope of the disclosure.

[0033] "Additive manufacturing" is the term used herein to describe a process that involves layer-by-layer building or additive fabrication (as opposed to material removal as in conventional machining processes). Such a process may also be referred to as a "rapid manufacturing process". Additive manufacturing processes include, but are no...

Abstract

A multi-material tower section (130) for a tower mast (102). The tower mast comprised of at least one multi-material tower section and a method for manufacturing the section. The section comprises atleast one additively manufactured wall structure (132) comprised of at least one first material and a plurality of additively manufactured internal reinforcement structures (142) comprised of at leastone additional material and disposed therewith the at least one additively manufactured wall structure.

Description

technical field [0001] The present invention relates to wind turbines, and more particularly to a wind tower structural section and method of fabrication for additive manufacturing of wind turbine towers. Background technique [0002] Generally, a wind turbine includes a rotor including a rotatable hub assembly having a plurality of blades. The blades convert wind energy into mechanical rotational torque, which drives one or more generators via a rotor. The generator is sometimes, but not always, rotationally coupled to the rotor through a gearbox. The gearbox increases the inherently low rotational speed of the rotor for the generator to efficiently convert the rotational mechanical energy into electrical energy that is fed into the utility grid via at least one electrical connection. The rotor, generator, gearbox and other components are typically mounted within a housing or nacelle positioned on a foundation comprising a truss or tubular tower. [0003] Wind turbine to...
