Latest Patents

Deveau holds a patent for a method of controlling the clearance between rotating and stationary components of a gas turbine engine. This patent, titled "Gas turbine engine active clearance control," discloses techniques for achieving close correspondence between the radial position of rotor blade tips and the circumscribing outer air seals. In one embodiment, turbine case temperature modifying air is provided in flow rate, pressure, and temperature varied as a function of engine operating conditions. The modifying air is scheduled from a modulating and mixing valve supplied with dual source compressor air. One source supplies relatively low pressure, low temperature air, while the other source supplies relatively high pressure, high temperature air. After the air has been used for active clearance control, it is then utilized for cooling the structure that supports the outer air seal and other high-pressure turbine component parts. This innovation represents a significant step forward in gas turbine engine design.
