  • METHODS AND APPARATUS TO TARGET ENGINE OPERATING CYCLE CONDITIONS FOR CLEARANCE CONTROL
    Publication number: 20240200465
    Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed. An example hybrid-electric gas turbine engine comprises: a first motor coupled to a first rotatable component; a second motor coupled to a second rotatable component; and control circuitry to: determine a current operating clearance of the hybrid-electric gas turbine engine; identify one or more parameters of a model of the hybrid-electric gas turbine engine for modification based on a difference between the current operating clearance and a desired operating clearance of the hybrid-electric gas turbine engine; and modulate power to at least one of the first motor or the second motor based on the identified one or more parameters to satisfy the desired operating clearance and maintain a thrust of the hybrid-electric gas turbine engine.

  • Deflector embedded impingement baffle
    Patent number: 7008183
    Abstract: An impingement baffle includes a perforate plate having a pattern of impingement holes. An imperforate deflector is spaced from the plate and is smaller than the plate for deflecting inlet air around the deflector to the holes. The baffle is disposed between a turbine shroud and supporting hanger, and the deflector is disposed between the hanger and the baffle.
