Patent number: 10914314Abstract: A modular fan assembly includes a center hub assembly and a first blade attached to the center hub assembly. The center hub assembly includes a first plate and a second plate each having an outer edge and a planar capture surface. The planar capture surfaces of the second plate is arranged parallel to the planar capture surface of the first plate. The first blade includes a mounting pad and a working portion. The mounting pad has opposite, parallel planar surfaces positioned in contact with the respective planar capture surfaces of the first and second plates. The working portion extends beyond the outer edges of the first and second plates. A thickness of the first blade is smaller proximate the outer edge of the first plate than at the mounting pad to create a first gap between the first blade and the first plate at the outer edge.Type: GrantFiled: November 8, 2017Date of Patent: February 9, 2021Assignee: Horton, Inc.Inventors: Kevin Cahill, Eric Strauss, Doug Burchett, Hooshang Didandeh, Charles Mark Shogren

Patent number: 10662975Abstract: A fan blade (134) includes a working region (148) having a leading edge (138) and a pressure side (136). A plurality of flow modification features (150-1 to 150-4) are positioned at the working region, including first and second flow modification features (150-1, 150-2, 150-3) each having a wedge shape with a pointed end (152) and a wider end (154), and located on the pressure side. A length of the first flow modification feature is less than a chord length of the fan blade, and the pointed end of the first flow modification feature is spaced from the leading edge. A length of the second flow modification feature is less than the chord length of the fan blade, and the pointed end of the second flow modification feature is spaced from the leading edge. The first and second flow modification features are spaced from each other to define a channel (156) therebetween.Type: GrantFiled: September 19, 2017Date of Patent: May 26, 2020Assignee: Horton, Inc.Inventor: Kevin Cahill

Patent number: 10415587Abstract: A method of making a modular fan includes positioning a mounting pad of a blade between two plates of a center hub assembly, aligning the blade such that the mounting pad is located radially inward of an outer edge of at least one of the two plates, and spacing the outer edge of the at least one of the two plates from the blade at the outer edge.Type: GrantFiled: October 14, 2016Date of Patent: September 17, 2019Assignee: Horton, Inc.Inventors: Kevin Cahill, Eric Strauss, Doug Burchett, Charles Mark Shogren
