A split case for a gas turbine engine includes multiple split case portions defining a turbine engine case section. Each of the split case portions has a first and second axially aligned split flange and a circumferential flange on an axial end. Each of the circumferential flanges includes a thermal expansion relief void.

A disclosed gas turbine engine includes a case for a case for a compressor section including a bleed air slot. The bleed air slot includes an inlet having a first area radially inward of an outlet having a second area with the second area being greater than the first area. The bleed air slot further includes a center portion disposed along a radial line extending from an axis of the engine and an elongated portion extending from the opening at an angle relative to a line normal to the radial line.

A bracket for mounting an accessory on an aircraft engine is disclosed. The bracket includes a mounting wedge (70) adapted to be secured to the engine, a carrier (120) which is supported by the mounting wedge and in turn supports an end of the accessory, and a lock (190) which is retained by the carrier and is longitudinally translatable with respect thereto between a closed position and a range of open positions. With the lock secured in the closed position, notched, inclined supporting and clamping surfaces (76), (90) on the mounting wedge cooperate with ridged, inclined mounting and locking surfaces (132), (200) on the carrier and lock respectively to clamp the carrier to the wedge. With the lock translated to an open position, the carrier can be mounted on or dismounted from the mounting wedge and the wedge can temporarily but reliably support the carrier and therefore an end of an accessory connected to the carrier.
