Stanley Hooker Sir Stanley George Hooker, FRS, DPhil, BSc, FRAeS, MIMechE, FAAAS, (30 September 1907 – 24 May 1984) was a Mathematician and jet engine engineer, first at Rolls-Royce where he worked on the earliest designs such as the Welland and Derwent, and later at Bristol Aero Engines where he helped bring the troubled Proteus turboprop, and Olympus turbojet to market, and then designed the famous Pegasus vectored thrust turbofan used in the Hawker Siddeley Harrier.

Bristol Proteus The Bristol Proteus was the Bristol Aeroplane Company's first successful gas turbine engine design, a turboprop that delivered just over 4,000 hp (3,000 kW). The Proteus was a two spool, reverse-flow gas turbine. Because the turbine stages of the inner spool drove no compressor stages, but only the propeller, this engine was classified as a free-turbine. It powered the Bristol Britannia airliner, small naval patrol craft, hovercraft and electrical generating sets. It was also used to power a land-speed record car, the Bluebird-Proteus CN7. After the merger of Bristol with Armstrong Siddeley the engine became the Bristol Siddeley Proteus, and later the Rolls-Royce Proteus.

Blackburn Skua The Blackburn B-24 Skua was a carrier-based low-wing, two-seater, single-radial engine aircraft operated by the British Fleet Air Arm which combined the functions of a dive bomber and fighter. It was designed in the mid-1930s and saw service in the early part of the Second World War. It took its name from the sea bird.

Superpower steam "Superpower steam" was a term coined by Lima Locomotive Works in the mid-1920s. It referred to steam locomotives with booster-equipped four-wheel trailing trucks supporting large fireboxes, as well as enlarged superheaters. The wheel arrangements introduced in the 1920s for these locomotives: the 4-6-4's, 2-8-4's, 4-8-4's and 2-10-4's, and in the 1930s, the 2-6-6-4's. The term "superpower" was often applied to all locomotives with 4 wheel trailing truck arrangements afterward, though many did not have boosters and almost all steam of any wheel arrangement built after that time had large superheaters.

Vedeneyev M14P The Vedeneyev M14P is a Russian nine-cylinder, four-stroke, air-cooled, petrol-powered radial engine. Producing 360 hp , its design dates from the 1940s (Kotelnikov 2005), and is itself a development of the Ivchenko AI-14 engine. The M14P has recently become increasingly popular in experimental aircraft and kit designs such as the Murphy Moose, Radial Rocket, Pitts Model 12, and others. Historically, the engine has been used extensively by the Yakovlev and Sukhoi Design Bureaus.

Swing-piston engine A swing-piston engine is a type of internal combustion engine in which the pistons move in a circular motion inside a ring-shaped "cylinder", moving closer and further from each other to provide compression and expansion. Generally two sets of pistons are used, geared to move in a fixed relationship as they rotate around the cylinder. In some versions the pistons oscillate around a fixed center, as opposed to rotating around the entire engine. The design has also been referred to as a oscillating piston engine, vibratory engine when the pistons oscillate instead of rotate, or toroidal engine based on the shape of the "cylinder".

Midland Railway 990 Class The Midland Railway 990 class was a class of 4-4-0 steam locomotive. Ten were built by the Midland Railway in 1907–1909, with simple expansion, to compare with the 1000 class compounds, with which they shared many features. Initially built as saturated, from 1910 to 1914, they were equipped with superheated boilers. These locomotives were well known for their work North of Leeds, over the demanding Settle and Carlisle route.

Harold Holcroft Harold Holcroft (12 February 1882 – 15 February 1973) was a British railway and mechanical engineer who worked for the Great Western Railway (GWR), the South Eastern and Chatham Railway (SECR) and the Southern Railway (SR). At the GWR, Holcroft helped the Chief Mechanical Engineer (CME), George Jackson Churchward, design the 4300 class 2-6-0 Moguls, and took the design principles for this class of locomotive with him when he moved to the SECR. Here, he worked as Assistant to Richard Maunsell and was involved with the design of the Maunsell Moguls, transferring to the Southern Railway when it was created by the amalgamation of the SECR with other railways at Grouping in 1923. After Maunsell's retirement in 1937, Holcroft continued to work for the Southern Railway under Oliver Bulleid until his retirement in 1946.

ABC Mosquito The ABC Mosquito was a 120 hp (90 kW) six-cylinder radial aero engine designed by the noted British engineer Granville Bradshaw for use in light aircraft. The single Mosquito engine was built by ABC Motors, first running in 1916. It is thought that the design resulted from a bet between Harry Hawker and Bradshaw, Hawker proposing that Bradshaw could not build and fly a six-cylinder radial engine. The Mosquito used copper-plated steel Gnat cylinders. The engine was not a success.

Bristol Pegasus The Bristol Pegasus is a British nine-cylinder, single-row, air-cooled radial aero engine. Designed by Roy Fedden of the Bristol Aeroplane Company, it was used to power both civil and military aircraft of the 1930s and 1940s. Developed from the earlier Mercury and Jupiter engines, later variants could produce 1,000 horsepower (750 kW) from its capacity of 1,750 cubic inches (28 L) by use of a geared supercharger.
