Attachment piece for attaching rear suspension of turboshaft engine to pylon of aircraft, has tapered ferrule portion comprising angular sector equal to specific values, where piece is arranged between high and low pressure turbine casings

摘要

The piece (19) has a tapered ferrule portion (20) comprising a predetermined angular sector approximately equal to 120 degrees, where the piece is arranged between a high pressure turbine casing (6) and a low pressure turbine casing (7). An upstream connection unit is engaged with an upstream flange of a tapered inter turbine casing (5), and a downstream connection unit is engaged with a downstream flange of the inter turbine casing. The connection units are presented in form of flanges of angular sector equal to that of the tapered ferrule portion. An independent claim is also included for a suspension of a turbojet engine to a pylon of an aircraft.
