Abstract: Seats and seat assemblies, such as for installation into aircraft, are described herein. In some embodiments, a seat assembly can include a framework configured to be mounted within an aircraft and a plurality of seats coupled to the framework. Each seat can include (a) a seat pan slidably coupled to the framework and (b) a seat back pivotally coupled to the framework and rotatable between an upright position and a reclined position. In some embodiments, the seat back is operably coupled to the seat pan such that movement of the seat back from the upright position to the reclined position moves the seat pan away from seat back to increase the effective recline of the seat.

Abstract: A bladed rotor disk assembly includes a plurality of circumferentially spaced apart blade root slots extending through the disk at an angle to the disk axial direction. Each slot has a radially inwardly facing load reaction surface along each side thereof extending continuously over less than the full the length of the slot in contact with a corresponding radially outwardly facing load reaction surface of a blade root disposed within the slot. This eliminates highly concentrated reaction loads adjacent the ends of the slot and results in a more uniform load distribution over the remaining smaller reaction surface area, reducing maximum stresses.
