摘要:
An arrangement (1) for suspending a jet engine (12) to a supporting structure (5) attached to an aircraft fuselage, includes a suspension beam (6) to which the engine casing (13) is fitted by a forward suspension (7), a rearward suspension (8) and at least one thrust rod (9) arranged at an angle relative to the suspension beam (6). In order to provide an arrangement for the suspension of a jet engine (12) which enables weight to be saved and deformation of the jet engine (12) to be reduced, the rearward suspension (8) and the thrust rod (9) are connected to the engine casing (13) by a lightweight framework (11).

A gas-turbine exhaust cone includes a cone shaped outside cone 1 closed in a flow direction, an inside cone 2 arranged in the outside cone 1 over at least part of the length of the exhaust cone, with the inside cone 2 being connected to the outside cone 1 via at least one helical partition wall 3, thereby forming an interspace 4 between the outside cone 1 and the inside cone 2. The interspace 4 is connected to inlet openings 5 at its inflow side and opens at an exit side 6 towards an interior 7 of the outside cone 1. A dampening element 8 is arranged in the outside cone 1 adjacent to the exit side 6 of the interspace 4.

This invention relates town ejector nozzle tube 1, having along its length an essentially constant, essentially oval hollow cross-section, with an inflow lip 2, having a pitch-circle type cross-section, being arranged at a flow leading-edge area of the ejector nozzle tube 1. The inflow lip 2 is provided with a plurality of grooves 3 issuing (4) to the top and bottom sides of the ejector nozzle tube 1 and connecting to an interior 5 of the ejector nozzle tube 1 formed by the hollow profile. It also relates to an aircraft engine with optimized oil heat exchanger with at least one oil cooler 6 disposed in a trailing-edge area 7 of an aerofoil-type structure 8, with at least one flow entrance area 9 being provided to supply ambient air to the oil cooler 6 disposed in a flow duct 10, and with an ejector nozzle tube 1 in accordance with one of the claims 1 to 3 being arranged downstream of the oil cooler 6 in the flow duct 10.
摘要:
A gas-turbine exhaust cone has an outer wall with a plurality of recesses, a honeycomb-structured layer arranged at the inside of the outer wall and extending along said inside of the outer wall, an inner wall connected to the honeycomb structure and extending essentially parallel to the outer wall, and at least one annular chamber centered on a central axis and adjoining the inner wall. The inner wall has passage recesses connecting the area of the honeycomb structure to the annular chamber, with the annular chamber being subdivided in the circumferential direction by at least one partition wall into several chambers. The partition wall is made from a sheetmetal-like material and has a plurality of raised and/or recessed areas in a uniform arrangement formed by shaping of the sheetmetal-like material.
