GB2378225A - Vertical axis turbine in building - Google Patents

Abstract

A wind turbine comprises a vertical driven shaft 9 supporting curved blades 2 via a central drum 7 having apertures. The blade trailing faces are corrugated 5, improving performance and the leading faces are cambered 4. Radially outside the blades lie adjustable inlet guide vanes 12 and outside that a building supporting the turbine assembly forms large wind collecting vanes 11, divide the building periphery into segments and forming convex sided ducting. Incoming airflow enters the segments on the side of the building facing the wind and is controlled by slats 14 pivotally mounted on the large vanes and by the guide vanes and fed to turn the blades. Excess airflow passes through the central drum ensuring all of the blades are active. The building forms part of the turbine, may be multi-storey and also houses accommodation e.g. offices, factories or a sports, civic and conference centre.

Description

<Desc/Clms Page number 1>

PAGE 1 KINETIC POWER HOUSE The Kinetic Power House is designed to supercede other forms of electrical power generating, in doing so it will safeguard the environment and help with the pollution clean up.

Excess energy will drive water pumps pumping water to greater heights as stored energy, methods of utilising this energy will not be mentioned in this specification.

The most important aspect of the Kinetic Power House is that the building is the machine, also that the machine can be utilised for all manner of industry such as factories, shopping centres, car parks, offices, housing, civic centres, sports centres, conference centres etc.

The Kinetic Power House can be scaled up or down depending on requirements.

The larger the scale the greater the energy production and facilities available. The technology of construction is new, using rapid and cost effective build, using advanced techniques and materials.

PAGE 2 KINETIC POWER HOUSE The Kinetic Power House is a large vertical turbine 1 the rotating assembly, composed of five or more blades 2 capped with circular plates top and bottom 3 the blades are cambered 4 at the leading face and corrugated on the trailing face 5 in the lateral vein, fenced 6 at either end of the lateral corrugation, blades 2 are centred onto the large hollow spindle drum 1 holed for air flows 8 then further attached to the torque shaft 9, the torque shaft is allowed a small amount of vertical movement on the main shaft bearings to ensure clearance on the electro magnetic opposing pole rails angled for stability, not shown, the torque shaft is geared to the electrical generators via constant speed drives, clutches and gearing not shown, the static turbine housing building 10 is composed of five or more large vanes 11 centred onto the entry guide vane assembly 12 in this case 72 degrees apart one face being flat the other face being aerofoil shape, the floor and roof 13 sloping reducing area onto the entry guide vane assembly 12 forming a convex ducting alone with the vanes 11, attached to each vane on the flat surface at the entry points are slats 14 which operate in conjunction with the entry guide vanes 12 depending on air speed and direction, the base 15 and roof area 16 are extensive and depends on requirements as to how many stories are required.

c KINETIC POWER HOUSE AIRFLOWS For this particular specification the design was five identical quadrants 72 degrees apart, the wind coming from any direction moves within a 36 degree band bringing into operation two or three quadrants, the airflow on entering the Power House moves past the slats down through the convex ducting onto the entry guide vanes which direct the airflow onto the turbine blades turning them at speed, excess air passes directly through the spindle drum accelerating over the camber on the trailing blades ensuring all blades on the rotating assembly are active, entry guide vanes and slats move in conjunction for any wind condition for optimum efficiency, the whole machine ensuring maximum pressure upwind with minimum pressure downwind under any condition, the entry guide vanes are closed for turbine shut down the turbine slowing to move onto its wheels off the opposing pole rails and finally braked.

Claims (2)

1. PAGE 4 KINETIC POWER HOUSE CLAIMS A Kinetic Power House able to generate electrical power utilising the building as part of the machine, the vertical turbine using a spindle drum allowing airflows to pass to trailing blades through vents in the drum ensuring all blades are active, the turbine operating on frictionless bearings, the building itself utilised as offices, factories, sports centre, conference centre, civic centre, housing etc. an independent power source or contributing to the national supply, as outlined in the specification, blades corrugated on the pressure sides rotated at speed improve performance.
