Dr Stewart Miller, managing director of Rolls-Royce’s aerospace group during the development of the Trent engine, has died at the age of 65.
Brought up in Kirkcaldy, Miller graduated from Edinburgh University with a first in mechanical engineering. He joined Rolls-Royce in 1954 and stayed with the firm until his retirement in 1996.
Early in his career he specialised in combustion, working on design of the Conway, Spey, RB162 and Ardour engines. From 1976 to 1984 he was chief engineer on the RB211-535 engine for the Boeing 757, heading the project.
Miller was made director of advanced engineering in 1984, and a board director, responsible for corporate engineering, in 1985. In 1993 he became director of engineering and technology.
As managing director of Rolls-Royce’s Aerospace Group during 1991-1992, Miller was responsible for development of the Trent engine, which won the Royal Academy of Engineering’s MacRobert Award in 1996.
Miller was awarded the British Gold Medal from the Royal Aeronautical Society in 1998, and the CBE in 1990.
Phil Ruffles, Rolls-Royce director of engineering and technology, said: `Stewart was a man of tremendous vision and vitality who made a major contribution in his field.’
