WO_2019242195_A1

Resumen de: AU2018414991A1

An enclosure with a frequency mixing and absorbing device on an outer surface is provided. The frequency mixing and absorbing device includes a deformable body located on an outer surface of the enclosure, the deformable body includes a flexible body and/or an elastic 5 body, the flexible body is a flexible hollow body or a flexible solid body, the elastic body is an elastic hollow body or an elastic solid body; and the deformable body is deformable under an action of an incoming flow. When the direction of the incoming flow is from left to right, it acts on the deformable body at a windward side, that is, the change of pressure will be converted into the volume change of the deformable body. In this way, the fluctuating energy of the incoming 10 flow can be absorbed and stored by the deformation of the deformable body, to realize disordering of the fluctuating energy, and the fluctuating energy is transferred to the volume change. During the process that the volume change of the deformable body is transferred downstream, the fluctuating energy is consumed and submerged, instead of directly acting on the outer surface of the enclosure. Therefore, with the arrangement of the deformable body, the 15 fluctuating excitation is self-consumed and submerged, the downwind resistance is reduced, and thereby suppressing the vibration.

Vertical axis multi level paddle wind turbine

NºPublicación: GB2575445A 15/01/2020

Solicitante:

ANGUS BLACK [GB]

Resumen de: GB2575445A

A vertical axis multi level paddle wind turbine comprises multiple levels of paddle blades 1 which rotate about turbine support shaft 3. The blades use the impulse force of the wind to create a high shaft torque with a low wind speed. The blades uses the paddle effect, due to the different wind forces acting on each side of the paddle blade, to reduce the wind drag or return force. This is done by rotating the turbine paddle blades to reduce their cross sectional area as they return into the wind direction. It naturally occurs due to the location of its off centre paddle blade support rod on the paddle blade and the use of a rotation stop to ensure maximum push by the wind on the drive side. The blades may be bespoke to suit their requirements by varying the paddle blade shape, colour and by having animated pictures on it. The blades may be used to show messages or other attractive features. It can increase the absorbed energy from the wind without increasing the Paddle Blade lengths.
