  • Additive manufactured case with internal passages for active clearance control
    Patent number: 10914185
    Abstract: An engine or engine casing having an inner annular case and an outer annular case. The engine casing is formed using an additive manufacturing technique such that the inner annular case and outer annular case is formed surrounding a hollow inner annular cavity. The annular cavity includes a pin bank connecting the inner annular case and outer annular case. The pin bank improves heat transfer between the inner and outer annular case and provide structural support to the inner and outer annular case. By providing fluid flow through the annular cavity, the turbine casing can be cooled and the radius of the casing can be controlled through the regulation of fluid travelling within the annular cavity. By controlling the fluid flow though the annular cavity, the engine case may be cooled to regulate its temperature in a wide variety of operating conditions.
