Abstract
A gimbal tube system for an onboard injector (OBI) includes a transfer tube having a first transfer tube end that can be mounted to an inner diameter of a stator platform and a second transfer tube end defining a transfer tube pivot connector. The system also includes a gimbal tube including a first gimbal tube end that defines a gimbal tube pivot connector that can movably mount to the transfer tube pivot connector such that the gimbal tube and the transfer tube can move relative to each other at a pivot joint defined between the transfer tube and the gimbal tube. The gimbal tube further includes a second gimbal tube end defining a nozzle that can be inserted into the OBI.
Claims20
A gimbal tube system for a tangential onboard injector (TOBI), comprising:
- a transfer tube including a first transfer tube end mounted to an inner diameter of a stator platform and a second transfer tube end defining a transfer tube pivot connector;
- and
- a gimbal tube including a first gimbal tube end that defines a gimbal tube pivot connector movably mounted to the transfer tube pivot connector such that the gimbal tube and the transfer tube are pivotable relative to each other at a pivot joint defined between the transfer tube and the gimbal tube, wherein the gimbal tube further includes a second gimbal tube end defining a nozzle inserted into the TOBI.
A tangential onboard injection system, comprising:
- a tangential onboard injector (TOBI) defining a plurality of gimbal tube orifices receiving a gimbal tube;
- and
- a gimbal tube system operatively disposed on the TOBI to supply the TOBI with airflow, the gimbal tube system including:
- a transfer tube including a first transfer tube end mounted to an inner diameter of a stator platform and a second transfer tube end defining a transfer tube pivot connector;
- and
- a gimbal tube including a first gimbal tube end that defines a gimbal tube pivot connector movably mounted to the transfer tube pivot connector such that the gimbal tube and the transfer tube are pivotable relative to each other at a pivot joint defined between the transfer tube and the gimbal tube, wherein the gimbal tube further includes a second gimbal tube end defining a nozzle that is inserted into the TOBI.
A method for installing a tangential onboard injection system, comprising:
- disposing a spring member on a tangential onboard injector (TOBI);
- and
- inserting a nozzle of a gimbal tube into the TOBI and in communication with the spring member thereby creating a spring force between the TOBI and the gimbal tube.
