Patent number: 11781504Abstract: A bleed plenum for a compressor section associated with a gas turbine engine includes a plenum chamber having a first wall spaced apart from a second wall to define a plenum slot configured to receive a flow of fluid from the compressor section. A slot angle of the plenum slot is defined between a centerline of the plenum slot and a longitudinal axis of the gas turbine engine and varies about a circumference of the bleed plenum. The second wall includes a bullnose having a wedge angle defined between the second wall and a surface associated with the compressor section. The bullnose faces into the flow of fluid through the plenum slot, and the wedge angle of the bullnose varies about the circumference of the bleed plenum.Type: GrantFiled: October 19, 2021Date of Patent: October 10, 2023Assignee: HONEYWELL INTERNATIONAL INC.Inventor: Masayoshi Shimo

Patent number: 10519976Abstract: An entrance stator in a turbofan has an airfoil shape with a leading edge and a trailing edge connected by surfaces which define a suction side and a pressure side. The entrance stator has a channel with an opening on the pressure side, extending to an exit on the suction side, having a pressure gradient between the opening and the exit. The channels are preceded with a ridge. The channels and the ridges control the boundary layer, enabling higher efficiencies. The channels and ridges add energy to the boundary layer to prevent separation.Type: GrantFiled: January 9, 2017Date of Patent: December 31, 2019Assignee: ROLLS-ROYCE CORPORATIONInventor: Masayoshi Shimo
