The CMC Leopard was a British light personal business jet developed in the 1980s. Two prototypes were built and flown, but the type was never put into production.

Design and development

The Leopard was a twin-jet, mid-wing monoplane of composite construction with all-swept flying surfaces and jet fighter-like styling, apart from the podded engines, mounted on each side of the rear fuselage. The entire canopy hinged forward to allow access to the four reclining seats. [1]

A mockup was completed in 1982, leading to a prototype (registration G-BKRL [2] ) built by the Designability company. The prototype first flew late in 1988. Development suffered a major setback when the engine manufacturer, Noel Penny Turbines, ceased business, leading to the grounding of the prototype. A second, refined prototype (registration G-BRNM [3] ) was then constructed to use Williams International turbofans. This aircraft also incorporated a pressurised cabin, revised undercarriage, and a generally strengthened airframe. This second prototype was unveiled at the 1996 Farnborough International Airshow and first flew on 9 April 1997.

The project never progressed beyond the two aircraft built, later redesignated Leopard Four to distinguish them from a six-seat variant proposed in 2001, the Leopard Six. The EJ22 engine could no longer be used due to exclusive deal between Williams and Eclipse, [4] resulting in the Six being proposed to make use of the larger FJ33. Chief aircraft designer and CMC chairman Ian Chichester-Miles died in 2009, bringing the enterprise to an end. [5]

Until 2007, both prototype Leopards, G-BKRL and G-BRNM, were on display at the Bournemouth Aviation Museum. With the museum temporary closure and relocation in 2008, only the former was retained and moved to the new site, while G-BRNM was acquired by the Midland Air Museum at Coventry Airport. [6] [7]

Gloster Meteor Britains first jet fighter, 1943-1980s

The Gloster Meteor is a fighter aircraft that was the first British jet fighter and the Allies' only jet aircraft to achieve combat operations during World War II. The Meteor's development was heavily reliant on its ground-breaking turbojet engines, pioneered by Frank Whittle and his company, Power Jets Ltd. Development of the aircraft began in 1940, although work on the engines had been under way since 1936. The Meteor first flew in 1943 and commenced operations on 27 July 1944 with No. 616 Squadron RAF. The Meteor was not a sophisticated aircraft in its aerodynamics, but proved to be a successful combat fighter. Gloster's 1946 civil Meteor F.4 demonstrator G-AIDC was the first civilian-registered jet aircraft in the world. Several major variants of the Meteor incorporated technological advances during the 1940s and 1950s. Thousands of Meteors were built to fly with the RAF and other air forces and remained in use for several decades.

Ilyushin Il-18 Soviet medium- to long-range airliner with 4 turboprop engines, 1957

The Ilyushin Il-18 is a large turboprop airliner that first flew in 1957 and became one of the best known and most durable Soviet aircraft of its era. The Il-18 was one of the world's principal airliners for several decades and was widely exported. Due to the aircraft's airframe durability, many examples achieved over 45,000 flight hours and the type remains operational in both military and civilian capacities. The Il-18's successor was the long range Il-62 jet airliner.

Vickers Viscount British four-engined medium-range turboprop airliner, 1948

The Vickers Viscount is a British medium-range turboprop airliner first flown in 1948 by Vickers-Armstrongs. A design requirement from the Brabazon Committee, it entered service in 1953 and was the first turboprop-powered airliner.

Heinkel He 280 Experimental jet aircraft

The Heinkel He 280 was the first turbojet-powered fighter aircraft in the world. It was inspired by Ernst Heinkel's emphasis on research into high-speed flight and built on the company's experience with the He 178 jet prototype. A combination of technical and political factors led to it being passed over in favor of the Messerschmitt Me 262. Only nine were built and none reached operational status.

The Grumman F9F Panther is one of the United States Navy's first successful carrier-based jet fighters, as well as Grumman’s first jet fighter. A single-engined, straight-winged day fighter, it was armed with four 20 mm (0.79 in) cannons and could carry a wide assortment of air-to-ground munitions.

British Aerospace 125 Business jet

The British Aerospace 125 is a twinjet mid-size business jet. Originally developed by de Havilland and initially designated as the DH.125 Jet Dragon, it entered production as the Hawker Siddeley HS.125, which was the designation used until 1977. Later on, more recent variants of the type were marketed as the Hawker 800.

The Sea Vixen was designed by the de Havilland Aircraft Company during the late 1940s at its Hatfield aircraft factory in Hertfordshire, developed from the company's earlier first generation jet fighters. It was later called the Hawker Siddeley Sea Vixen after de Havilland was absorbed by the Hawker Siddeley Corporation in 1960.

Scottish Aviation Twin Pioneer Type of aircraft

The Scottish Aviation Twin Pioneer was a British STOL transport aircraft built by Scottish Aviation Limited at Prestwick Airport, Scotland, during the 1950s. It was designed for both civil and military operators. It was conceived as a twin-engined version of the Pioneer light transport. Both aircraft required "an area only 30m (99ft) by 275m (902ft) in which to operate."

Lockheed JetStar Executive transport jet by Lockheed

The Lockheed JetStar is a business jet produced from the early 1960s to the 1970s. The JetStar was the first dedicated business jet to enter service, as well as the only such airplane built by Lockheed. It was also one of the largest aircraft in the class for many years, seating ten plus two crew. It is distinguishable from other small jets by its four engines, mounted on the rear of the fuselage, and the "slipper"-style fuel tanks fixed to the wings.

Hiller VZ-1 Pawnee Type of aircraft

The Hiller VZ-1 Pawnee was a unique direct-lift rotor aircraft, using contra-rotating ducted fans for lift inside a platform upon which the single pilot shifted body weight for directional control. The platform was developed starting in 1953 under an Office of Naval Research (ONR) contract to Hiller Aircraft, and flew successfully beginning in 1955.

The tailwheel undercarriage layout was also dated and a disadvantage.
