Abstract
A spacing arrangement for a gas turbine engine 10. The spacing arrangement being arranged such that as a rotor blade 26 of a compressor 13 rotates, the rotor disc 28 will move outwards and forwards to maintain a substantially constant gap 36 between the rotor blade 26 and an inclined casing 20.
Claims19
A spacing arrangement for a gas turbine engine, the arrangement comprising a first rotatable member and a second non rotatable member with a gap defined between facing surfaces respectively on the first and second members, the gap being inclined relative to the rotational axis of the first member;
- characterised in that axial movement means are provided which automatically cause relative movement of a one of the first and second members in a direction to tend to increase the gap between the facing surfaces, in response to the rotational speed of the first member.
