A wonderful presentation apprentice model of the Rolls Royce 'High By Pass Ratio' jet engine RB211-524. This model is in polished and brushed alloys and mounted on a marble plinth by a brass/bronze bracket. Even the jet turbine blade is made so that it spins.
Developed at Derby, the initial costs of this engine drove Rolls Royce into insolvency in February 1971. The company was rescued by unusually speedy action from the government at that time; but the RB211 programme had to stand on its own merits. which, under the engineering brilliance of Sir Stanley Hooker and the tough financial expertise of Sir Arnold Weinstock, it did, and went on to become the world leading power unit of choice for aircraft manufacturers as well as for use in other applications.
