The Derby & Hucknall Branch focuses on the Rolls-Royce Company and its ancestors, FH Royce and Company, Royce Limited and CS Rolls and Company. The Trust is a world authority on the evolution of Rolls-Royce as a company and on its aero engines and other products.
The collection in Derby is housed over two sites and contains over 200 engines. The exhibits chronicling not only the history of Rolls-Royce, but that of many of the companies which have become part of the Rolls-Royce family. The majority of the exhibits relate to aero engines but there are also vehicle, marine and industrial diesel and gas turbine engines, and a display of rockets. Together with the Coventry collection and several engines from the Bristol collection, the Derby collection is a comprehensive history of propulsion on land, on the sea and in the air.
At Hucknall there is a smaller collection of engines which shows the work of the former Flight Test Department and other outdoor test activities conducted at Hucknall since 1935.
The Derby and Hucknall Branch are custodians of an extensive archive of documents and drawings.
