Patent number: 11579039Abstract: A test apparatus for torsional testing of a wind turbine blade is provided. The apparatus includes a test stand for rigidly supporting the wind turbine blade; a load frame for mounting on the wind turbine blade at a testing position along the length of the blade; and an actuator connected to the load frame for twisting the blade via the load frame. The load frame includes an outer frame to which the actuator is connected and a profiled insert held within the outer frame and defining a profiled aperture corresponding to the profile of the blade at the testing position. The profiled insert encloses and is in direct contact with the outer surface of the blade over substantially the entire profile of the blade. A system and method of torsional testing of a wind turbine blade and a load frame for the test apparatus are also provided.Type: GrantFiled: November 29, 2017Date of Patent: February 14, 2023Assignee: Vestas Wind Systems A/SInventors: William David Richards, Pierre-Emmanuel Verrien, Michael Dann

Patent number: 11530668Abstract: A closed cycle regenerative heat engine has a housing defining a chamber. A displacer is housed in the chamber. A power piston is housed in the chamber. The displacer is resiliently deformable from a rest condition in response to displace the working fluid in the chamber. The displacer may be a multi-start volute spring. The displacer may be provided with a heat storage reservoir to store heat received from a working fluid as the working fluid is displaced from a heating location in the chamber to a cooling location in the chamber and reject heat to the working fluid when the working fluid is displaced from the cooling location to the heating location. The resiliently deformable displacer may comprise two components with an air space defined between the two components.Type: GrantFiled: May 25, 2021Date of Patent: December 20, 2022Assignee: Stirling Works Global LTDInventors: Michael Dann, Graham Nicholson

Patent number: 11272593Abstract: An illumination system includes an illumination source configured to emit illumination light and a dispersive optical element configured to generate an angularly dispersed optical signal from the illumination light that is used to generate a spectral image. A digital micro-mirror device (DMD) includes an array of reflective elements that receive the spectral image and direct a portion of the spectral image to an integrating sphere. A controller is configured to calculate a subset of an array of reflective elements of the DMD to activate based on a target illumination output signal using a calibration model of the illumination system. The controller is also configured to activate the subset of the array of reflective elements to change the portion of the spectral image directed to the integrating sphere to generate an illumination output signal that substantially matches the target illumination output signal.Type: GrantFiled: July 15, 2020Date of Patent: March 8, 2022Inventors: Jeffrey William Holt, Erik Skarin, Mark Duquette, Jonathan D Scheuch, Michael Dann

Patent number: 11022067Abstract: A closed cycle regenerative heat engine has a housing (12) defining a chamber (14). A displacer (18) is housed in the chamber. A shaft (24) is connected with the displacer and extends from the chamber. A power piston (30) is housed in the chamber. The displacer (18) is secured to the housing (12) and is resiliently deformable from a rest condition in response to movement of the shaft (24) to displace the working fluid in the chamber. The displacer may be a multi-start volute spring. The displacer (18) may be provided with a heat storage reservoir to store heat received from a working fluid as the working fluid is displaced from a heating location in the chamber (14) to a cooling location in the chamber and reject heat to the working fluid when the working fluid is displaced from the cooling location to the heating location.Type: GrantFiled: September 24, 2018Date of Patent: June 1, 2021Assignee: Stirling Works Global LtdInventors: Michael Dann, Graham Nicholson
