Abstract
Disclosed herein is a gimbal body comprising: an end part (51) for use in welding the gimbal body to a pipe; and a main body (53) attached to the end part (51); wherein: the end part (51) is made of a first material; and the main body (53) is made of a second material that is different from the first material. Embodiments provide a new method of manufacturing a gimbal that allows the use of the most appropriate materials for high temperature and high pressure performance whilst overcoming manufacturing and installation problems experienced by known gimbals constructed with such materials.
Claims16
A gimbal body comprising:
- an end part for use in welding the gimbal body to a pipe;
- and
- a main body attached to the end part;
- wherein:
- the end part is made of a first material;
- and
- the main body is made of a second material that is different from the first material.
A method of manufacturing a gimbal body, the method comprising:
- solid state welding an end part of the gimbal body to a main body of the gimbal body;
- wherein:
- the end part is for use in welding to a pipe;
- the end part is made of a first material;
- and
- the main body is made of a second material that is different from the first material.
The gas turbine engine according to 15, wherein:
- the turbine is a first turbine, the compressor is a first compressor, and the core shaft is a first core shaft;
- the engine core further comprises a second turbine, a second compressor, and a second core shaft connecting the second turbine to the second compressor;
- and
- the second turbine, second compressor, and second core shaft are arranged to rotate at a higher rotational speed than the first core shaft.
