Silent Operation
Critical for domestic installations - the SWIFT Rooftop Wind Energy System™ is the quietest wind system currently available. Our patented acoustic suppression aerodynamics, notably the ring diffuser, remove noisy, turbulent air currents at the blade tips. In addition the direct driven generator contains no gear box, which means there is no mechanical noise. The SWIFT™ always operates below background noise, thereby making it virtually inaudible.
The Diffuser Ring - Silent Rotor Design
The primary reason for the SWIFT™ excellent noise characteristics is the diffuser ring. The diffuser ring is the circle that connects all the rotor blades at the blade tips.
The diffuser ring allows the airflow to drip softly and silently off the rotor without generating tip vortex noise and therefore solves the acoustic problems that afflict turbines with traditional rotors.
We hold the patents for the use of diffuser ring and we are therefore the only manufacturer capable of producing a truly silent turbine.
To see, but not hear the silent rotor in action, take a look at the following video that appeared on the BBC's Newsnight programme. Watch It Now!
Anti-Vibration Mounting Brackets
The Swift™ Rooftop Wind Energy System can be both building mounted or free standing.
When mounting a wind turbine on a building, the mounting system must ensure that minimal vibrations are transmitted to the structure.
The Swift™ wind turbine building mounting systems are scientifically designed to dampen all resonances that may be encountered during normal operation of the turbine. The mounting brackets have integrated anti-vibration technology that ensures that no discernable vibration is transmitted to the structure.
Acoustic Performance and Analysis
Renewable Devices Swift Turbines Ltd. has conducted its own measurements
of the acoustic properties of the turbine in operation, however, we currently have under commission an
independent acoustic analysis of the Swift(tm) Rooftop Wind Energy
System to provide independent verification of our own findings.
Trials conducted by Australian wind consultancy firm Garrad Hassan said the turbine "emitted very little noise", which was an "extremely attractive asset for an urban turbine"
