Publication number: 20160238030Abstract: A motor includes a cylindrical housing, a cooling fan, and a rotating shaft. The cylindrical housing defines at least one upstream through hole at its circumferential wall. The cooling fan is mounted at the rotating shaft for generating airflow towards the cylindrical housing for dissipating the heat generated in the motor. The hollow hood is mounted to the cylindrical housing such that a head portion is located above the upstream through hole, thus defining an annular air-guiding channel therebetween, which can receive the airflow generated by the cooling fan and guide the airflow to enter the cylindrical housing via the upstream through holes, so that the heat generated therein can be dissipated effectively. Thus, heat is not easy to accumulate in the motor, and the performance and service life of the motor can be increased.Type: ApplicationFiled: February 8, 2016Publication date: August 18, 2016Inventor: Wen-San CHOU

Publication number: 20160238032Abstract: A mounting system for a gas turbine engine includes a compressor case portion, an inlet frame, an outlet frame, and a mounting structure. The compressor case portion houses rotatable compressor blades. The inlet frame connects to an inlet end of the compressor case. The outlet frame connects to an outlet end of the compressor case portion at an end opposite the compressor case inlet end. An axially fore mounting structure of the mounting structure connects to the inlet frame. An axially aft mounting structure of the mounting structure connects to the outlet frame. A bridging structure of the mounting structure is offset from the compressor case and connects the fore and aft mounting structures, thereby bridging engine loads across the inlet and outlet frames to reduce load induced distortion of the compressor case portion.Type: ApplicationFiled: August 1, 2014Publication date: August 18, 2016Applicant: United Technologies CorporationInventors: James D. Hill, Gabriel L. Suciu, Jesse M. Chandler
