Abstract: A running-gap control system of an aircraft gas turbine with a core engine including a turbine whose blade rows have a running gap 13 to the turbine casing 12, with the turbine casing 12 being surrounded by a core-engine ventilation compartment 15 enclosed by a fairing 2 of the core engine, with the fairing 2 forming an inner wall of a bypass duct 1. Air from the bypass duct 1 can be introduced via at least one inlet nozzle 5 into a cooling-air distributor 7 by a control system 6, 10, 11 and the air is subsequently returned to the bypass flow 3.

Abstract: 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).

Abstract: On a high-pressure turbine rotor wheel, where a blade neck interspace (14) exists between two adjacent turbine blades (4) which is defined by the disk lobe (2) and the opposite blade necks (5) and blade platforms (6), part of the air supplied by the high-pressure cooling channel (9) is passed via a diverter cooling channel (10) into the blade neck interspace (14) to effectively cool the blades and the disk rim (1) in this area and to simultaneously supply the low-pressure channels (12) with cooler air and displace the hot sealing air. Thus, the life of the turbine rotor wheel is increased with simple means.
