Abstract: An indexable cutting insert includes at least two side edges each defining an indexable edge of the insert and at least two cutting teeth are on each indexable edge. The cutting insert includes locating means on a plane of the upper face and/or a plane of the lower face. When mounted on a material removal tool, the locating means cooperate with receivers on the working face of the material removal tool to constrain degrees of freedom of the cutting insert. Further, the mounted cutting inserts each locate the radial edge of the cutting teeth in the active position on a common circumference of a circle centered on an axis of rotation of the material removal tool. A mounting system per see is also disclosed as well as a method of removing material from a workpiece with the material removal tool.

Abstract: A cascade set for creating sufficient drag to slow an aircraft is disclosed. The cascade set includes one or more supporting vanes. A plurality of turning vanes are connected to the supporting vanes, and the turning vanes include forward and aft turning vanes. The forward turning vanes have a larger surface area than the aft turning vanes.

Abstract: A thrust reverser system for a gas turbine engine includes a duct including a cowling movable between an open position and a closed position in a direction transverse to a centerline of the gas turbine engine. The thrust reverser is supported within the cowling and movable between an axial closed position, an axial intermediate position and an axial open position. A controller is actuateable to command movement of the thrust reverser from the axial closed position to the axial intermediate position such that the cowling is free to move to the open position.
