The Midland Railway Institute on Railway Terrace, Derby, was opened in February 1894 as a cultural and educational centre for railway workers. At one time it contained a library of some 18,000 books, a concert hall with a stage and sitting for 500 people. In addition there were several other rooms set on one side for dining, meetings and games. In 1980 the Railway Institute had been leased off to the Post Office Social Club but that closed in 1994. Following the failure of plans to convert it to an arts centre, it was opened as a pub and party venue in 1996.

Bomb aimer's position in the nose of a Canberra bomber at the Rolls-Royce Heritage Centre in Derby. There wasn't much room.

Rolls-Royce Trent turbofan engine at the Heritage Trust Museum in Derby. I am unsure which model of the engine this is but it is one of the more recent developments. On the left is an earlier version on which can be seen the kevlar layer to stop flying debris if the engine is damaged or parts break off. The newer engine omits this feature as the protective casing is machined from titanium.

This large wooden structure is a full scale "mock-up" of the Marine Spey SMIC propulsion unit, used at Rolls-Royce, Ansty, to finalise pipe runs, wiring schemes, component siting, etc., prior to production. An exhibit in its own right as an example of patternmaking, it is a dimensional replica of what would be the starboard unit in the two-Spey engine room of, for example, a Type 22 frigate of the Royal Navy and gives an accurate representation of its layout. Its final use at Ansty, however was to facilitate its projected installation in a large hydrofoil ferry for Sweden. The SM range originated in a M.O.D.-funded design study in 1972 for an engine of a size between the Olympus TM and the Tyne RM, although at that time no application existed. Development started in 1977 and the engine selected was the Allison TF4IA licence-built Rolls Royce Spey as being the latest uprated Spey available, used in the Vought A7E Corsair strike aircraft of the United States Navy. In addi¬tion to being marinised the main modification was the cropping of the fan section of the LP compressor and redesign of the casing. An en¬tirely new control system was also developed by Lucas. Depending on the application, power ranges from 14,750 BHP (11 Mw) of the SM1A to 20,800 BHP (15.5 Mw) of the SMIC and could be further uprated. Its specific fuel consumption is almost half that of its predecessors. The first two SMIA production units, built and tested at Ansty, were installed in HMS Brave "type 22 frigate in 1983 in place of the originally specified Olympus TM3B. The Marine Spey was installed in 21 frigates of the Royal Navy combining with Tyne RM3C (Type 22) or diesel electric (Type 23). It was also be used in 8 frigates of the Royal Netherlands Navy and in 12 destroyers end 6 frigates of the Maritime Self-Defence Force of Japan. In the Asagiri class of destroyer, the Japanese reverted to the original concept of the Spey providing all the propulsion power, in this case 4xSMIA. However, in common with most of its overseas defence procurement, Japan manufactured under licence the Spey SM series and other Rolls-Royce machinery.

The Hawk is a British aero engine designed by Rolls-Royce in 1915. Derived from one bank of six cylinders of the Rolls-Royce Eagle engine, it produced 75 horsepower at 1,370 rpm. Power was progressively increased to 91 hp by February 1916, and 105 hp by October 1918. After Rolls-Royce made the prototypes, the Hawk was manufactured under licence by Brazil Straker in Bristol between 1915 and 1918. During this period 204 engines were built, and the Hawk earned a reputation for high reliability. It is said that Royce developed the engine having seen coastal blimps struggling over the English Channel with unreliable and underpowered engines. Many engines of this type were used to power the SSZ (Sea Scout Zero) class coastal patrol airships of which 76 were built. They were capable of patrols of 30 hours duration.

Stained glass window memorial at Rolls Royce, Derby. This is the Rolls Royce company's tribute and the wording at the bottom of the glass says: "This window commemorates the pilots of the Royal Air Force who in the Battle of Britain turned the work of our hands into the salvation of our country".
