Abstract: An example system includes one or more heaters configured and positioned to add thermal energy to one or more portions of a gas turbine engine after the gas turbine engine was in operation, wherein the thermal energy minimizes or prevents undesired contact or seizing of a rotor of the gas turbine engine with another component of the gas turbine engine due to warping of the rotor due to uneven cooling of the gas turbine engine after the operation. The system further includes a controller configured to control operation of the one or more heaters.

Abstract: A battery housing for an aerospace battery may include a first endplate; a flange; and an elliptical cylinder extending from a first cylinder end to a second cylinder end. The first cylinder end of the elliptical cylinder may be welded to the first endplate, and the second cylinder end of the elliptical cylinder may be welded to the flange. The elliptical cylinder is formed from a sheet of material comprising a first sheet end and a second sheet end. The first sheet end may be welded to the second sheet end at a weld location that runs from the first cylinder end to the second cylinder end at a perimeter location that is calculated to experience a reduced stress during pressurization of the housing.

Abstract: In examples, a clutch assembly includes a first clutch member disposed near a first end of a first shaft. The first clutch member defines a first surface. The first shaft includes a starter motor coupled to a second end of the first shaft. The clutch assembly includes a second clutch member disposed near a first end of a second shaft. The second clutch member defines a second surface opposing the first surface, and the second shaft includes an accessory gearbox of a gas turbine engine coupled to a second end of the second shaft. The surfaces of the first and second clutch member engage such that rotational motion is transferred between the first clutch member and the second clutch member. The first clutch member and the second clutch member are configured to passively disengage from each other and actively reengage with each other.
