Benefits of technology

This patented design allows for better control over how much material (such as lamina) needs to be removed during operation without causing damage on any part inside it. It also improves fatigue resistance by allowing some parts within certain areas to move more freely compared to others. Additionally, this design enables efficient use of space while maintaining high-quality output levels through optimal pitch angle adjustment.

Problems solved by technology

This patented describes two technical problem addressed during this patents' research: how to design better bladed materials that have improved impact resistance without increasing their weight or making them thicker than usual while still maintaining good aerodynamic characteristics (such as strength) at high speeds when used with modern technology equipment like electricity generating machines.

Abstract

The invention relates to a blade and a wind generating set. The blade comprises a blade body, the blade body is axially provided with a blade tip part, a blade root part and a maximum chord length part, the blade tip part and the blade root part are oppositely arranged, the maximum chord length part is located between the blade tip part and the blade root part, and the blade body is in smooth curved surface transition from the maximum chord length part to the blade root part. The length size of the blade root part in the chordwise direction of the blade body is larger than the length size of the blade root part in the width direction of the blade body and smaller than or equal to the length size of the maximum chord length part in the chordwise direction, and the width direction, the axial direction and the chordwise direction are perpendicular to one another. According to the blade and the wind generating set in the embodiment, the wind energy utilization rate of the wind generating set can be guaranteed through the blade, and the power generation benefit of the wind generating set is improved.
