The Napier Sabre is a British H-24-cylinder, liquid-cooled, sleeve valve, piston aero engine, designed by Major Frank Halford and built by D. Napier & Son during World War II. The engine evolved to become one of the most powerful inline piston aircraft engines in the world, developing from 2,200 hp (1,600 kW) in its earlier versions to 3,500 hp (2,600 kW) in late-model prototypes.
The Napier Lion is a 12-cylinder, petrol-fueled 'broad arrow' W12 configuration aircraft engine built by D. Napier & Son from 1917 until the 1930s. A number of advanced features made it the most powerful engine of its day and kept it in production long after other contemporary designs had been superseded. It is particularly well known for its use in a number of racing designs, for aircraft, boats and cars.
The Gee Bee Model R Super Sportster was a special-purpose racing aircraft made by Granville Brothers Aircraft of Springfield, Massachusetts at the now-abandoned Springfield Airport. Gee Bee stands for Granville Brothers.
The Hughes H-1 Racer is a racing aircraft built by Hughes Aircraft in 1935. Utilising different wings, it set both a world airspeed record and a transcontinental speed record across the United States. The H-1 Racer was the last aircraft built by a private individual to set the world speed record; most aircraft to hold the record since have been military designs.
The Blackburn Firebrand was a British single-engine strike fighter for the Fleet Air Arm of the Royal Navy designed during World War II by Blackburn Aircraft. Originally intended to serve as a pure fighter, its unimpressive performance and the priority allocation by the Ministry of Aircraft Production of Napier Sabre engines to the Hawker Typhoon caused it to be redesigned with an alternate engine as a strike fighter to take advantage of its load-carrying capability. Development was slow and the first production aircraft was not delivered until after the end of the war. Only a few hundred were built before it was withdrawn from front-line service in 1953.
The Macchi M.C. 72 is an experimental floatplane designed and built by the Italian aircraft company Macchi Aeronautica. The M.C. 72 held the world speed record for all aircraft for five years. In 1933 and 1934 it set world speed records for piston engine-powered seaplanes; the latter still stands.
The Boulton Paul P.92 was a British design by Boulton Paul for a two-seat, turret-armed, twin-engine heavy fighter and ground attack aircraft to meet Air Ministry Specification F.11/37. Only a half scale prototype – the P.92/2 – was built and tested as check on aerodynamics before the project was cancelled in 1940.
The Martin-Baker MB 3 was a British prototype fighter aircraft, developed from Martin-Baker’s earlier private ventures, the MB 1 and the MB 2. The design was notable for its heavy armament of six 20 mm Hispano cannons. The fatal crash of the only prototype in September 1942 led to the cancellation of the programme. The design would carry over into a planned MB 4, but this cancelled in favour of a moderate re-design in the form of the MB 5.
The Supermarine S.5 was a 1920s British single-engined single-seat racing seaplane built by Supermarine. Designed specifically for the Schneider Trophy competition, the S.5 was the progenitor of a line of racing aircraft that ultimately led to the Supermarine Spitfire fighter.
The Heston JC.6 was a British prototype air observation post aircraft designed and built by the Heston Aircraft Company Limited, who had previously built the Heston Phoenix, the Heston T.1/37 and the Napier-Heston Racer. The JC.6 was also known as the Heston A.2/45 or the Heston AOP.
The Gloster VI was a racing seaplane developed as a contestant for the 1929 Schneider Trophy by the Gloster Aircraft Company.
The Navy-Wright NW series, also called the Mystery Racer were racing aircraft built by Wright Aeronautical Corporation at the request of the US Navy. Although innovative, both prototype racers were lost before achieving their true potential.
The Gloster II was a British racing floatplane of the 1920s. A single-engined biplane, two were built to compete in the 1924 Schneider Trophy air race. However the crash of the first prototype during testing meant that it could not be made ready for the race, which was postponed. The second aircraft was also lost in a crash.
The Verville VCP was an American single-engined biplane fighter aircraft of the 1920s. A single example of the VCP-1 was built by the United States Army Air Service's Engineering Division, which was later rebuilt into a successful racing aircraft, while a second, modified fighter was built as the PW-1.
The SK-2, was a fighter aircraft designed and built in the USSR from 1940.
Heston Aircraft Company was a British aircraft manufacturer based at Heston Aerodrome, Middlesex, England.
The Yakovlev Yak-1000 was a Soviet supersonic technology demonstrator intended to evaluate the aerodynamic layout and field performance of the cropped delta wing discussed in captured German documents in combination with the new Lyulka AL-5 turbojet. The tandem undercarriage proved to be unsatisfactory and there were serious flight stability problems related to the delta wing, enough so that it never flew after an accident during taxiing tests.
The Hawks Miller HM-1, named Time Flies was an American racing aircraft that was the joint project of pilot-owner, Frank Hawks and Howell W. "Pete" Miller, chief engineer for the Granville Brothers. Although very advanced for its time with an enclosed cockpit that highlighted its streamlined lines, development ended after a crash during testing. A completely new design emerged when the aircraft was re-configured as a two-seat military aircraft.
The Military Aircraft HM-1, derived from the earlier Hawks Miller HM-1 racing aircraft nicknamed, "Time Flies" was an American prototype attack/observation aircraft. The HM-1 did not achieve production after the sole example was destroyed during testing.
Arthur Ernest Hagg was a British aircraft and boat designer.
