Abstract:

Stator structure for a gas turbine engine is disclosed which has retainers 26, 28 for engaging a heavy component, such as an electronic engine control 18. The retainers restrain the component against movement during installation. Various construction details which permit the stator structure to engage the component during assembly and yet allow for easy removal of the component are developed. In one embodiment, the stator structure includes a pair of circumferentially spaced retainers 26, 28 having channels 44 which open to each receive a mating element 46 on an engine component to support and position the component during installation.
