ROBIN RALPH JAMISON 12 July 1912—18 March 1991 Elected F.R.S. 1969 By L. F.R.S., M.A. G.L. H aworth, N edham and W ilde Early life and education ROBIN RALPH JAMISON (RRJ) was bom in Horsham, Sussex, on 12 July 1912. He was the third of four brothers bom to Reginald Jamison and Eanswythe Elstreth Heyworth. Two large family portraits of RRJ’s maternal grandparents have always adorned the hall of RRJ’s residence in Bristol, and two senior test pilots from the same Heyworth family served Rolls- Royce at Hucknall for many years. Both RRJ’s father and his grandfather were medical prac titioners and, at one time, it was thought that RRJ too would follow them into the profession.

Whilst at uni versity he became increasingly interested in aero engines, and having gained his second degree, decided to move back to the UK because there were few career opportunities for aero engineers in South Africa at that time.

Bearings on this tube support the discs so as to permit free rotation in either direction, and the blading is designed to drive alternate discs in opposite directions. Thus, for given incident Mach numbers on the blading, the rotation stresses are a quarter of what they would have been in a conventional machine in which alternate rows are stationary.
Robin Ralph Jamison 179 the sudden disappearance of an engine and a programme that he had been able to call his own for four years. Gas turbine work was now centred on the Whittle derivations at Bamoldswick, whilst RRJ remained at Derby, working under J.E. Ellor on turbine engine controls (5, 6) and exhaust reheat. During this period he started contemplating a return to South Africa, as evidenced by letters to his wife’s father in Cape Town.
180 Biographical Memoirs In the autumn of 1949 it became urgent for the Engine Division to provide rigs and tech nical support for the RAE test vehicle and M.A. Nedham was appointed Engineer-in-Charge of Ramjets. A small and competent team was built up for this and to provide some help with the GW project design work in the Aircraft Division.
