Patent number: 10502095Abstract: A turbine engine includes a compressor section, a combustor section in fluid communication with the compressor section, a high pressure turbine in fluid communication with the combustor, a low pressure turbine in fluid communication with the high pressure turbine, and a mid-turbine frame located axially between the high pressure turbine and the low pressure turbine. The mid-turbine frame includes an outer frame case, an inner frame case, and a plurality of hollow spokes that distribute loads from the inner frame case to the outer frame case. The spokes are hollow to allow cooling airflow to be supplied through the spokes to the inner frame case.Type: GrantFiled: November 1, 2016Date of Patent: December 10, 2019Assignee: United Technologies CorporationInventors: Paul K. Sanchez, Kalpendu J. Parekh, William A. Daniels, John S. Tu
