TURBINE ENGINE WITH TOBI SUPPORTING VANES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18302976 titled 'TURBINE ENGINE WITH TOBI SUPPORTING VANES
Simplified Explanation
The patent application describes a gas turbine engine with a row of vanes arranged around a central axis.
- The vanes have internal cavities and outlet ports for cooling air.
- A tangential onboard injector (TOBI) supports the vanes at the inner diameter of the row.
- The TOBI has fore and aft annular walls and an outer diameter annular wall, creating an annular plenum.
- The outer diameter annular wall has TOBI inlet ports connected to the vane outlet ports, receiving cooling air from each vane into the plenum.
- The TOBI has axially-oriented nozzles to discharge the cooling air from the plenum in an aft direction.
Original Abstract Submitted
A gas turbine engine includes a circumferential row of vanes arranged about a central engine axis. The vanes include respective internal cavities and vane outlet ports for conveying cooling air. A tangential onboard injector (TOBI) radially supports the vanes at an inner diameter of the circumferential row. The TOBI includes fore and aft annular walls and an outer diameter annular wall. The fore and aft annular walls and the outer diameter annular wall define an annular plenum. The outer diameter annular wall includes TOBI inlet ports that are connected, respectively, with the vane outlet ports to receive the cooling air from each of the vanes into the plenum. The TOBI includes axially-oriented nozzles for discharging the cooling air from the plenum in an aft direction.
