RB211-22B Model Engine

One in a collection of three apprentice and presentation models of versions of the Rolls Royce 'High By Pass Ratio' jet engine RB211.

This model is a mid-1970's version 22B developed for the Lockheed Tri-Star; machined in polished metal alloys and mounted on a mahogany plinth by a blacked sweeping bracket.

Developed at Derby, the initial costs of this engine drove the entire company into insolvency in February 1971. Rolls Royce 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 airlines and other applications.
