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 developmentThe 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 {{Airreg|G|BKRL}}) 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 {{Airreg|G|BRNM}}) 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 Six would not be able to use the EJ-22 engine due to exclusive deal between Williams and Eclipse.[2] Chief aircraft designer and CMC chairman Ian Chichester-Miles died in 2009, bringing the enterprise to an end.[3] Aircraft on displayUntil 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.[4][5] Specifications (second prototype){{aerospecs|ref= |met or eng?=eng |crew=One pilot |capacity=3 passengers |length m=7.54 |length ft=24 |length in=9 |span m=7.16 |span ft=23 |span in=6 |width m= |width ft= |width in= |height m=2.06 |height ft=6 |height in=9 |wing area sqm=5.85 |wing area sqft=63 |empty weight kg= |empty weight lb= |gross weight kg= |gross weight lb= |eng1 number=2 |eng1 type=Williams FJX-1 |eng1 kn=3.1 |eng1 lbf=700 |eng2 number= |eng2 type= |eng2 kn= |eng2 lbf= |max speed kmh=869 |max speed mph=540 |cruise speed kmh= |cruise speed mph= |range km=2,778 |range miles=1,726 |endurance h= |endurance min= |ceiling m=16,765 |ceiling ft=55,000 |glide ratio= |climb rate ms=32.7 |climb rate ftmin=6,340 }}{{aircontent |related= |similar aircraft= |lists= |see also= }} References{{Commons category}}1. ^{{cite |url=https://www.flightglobal.com/pdfarchive/view/1986/1986%20-%202313.html?search=chichester-miles |title=Leopard ready to leap |work=Flight International |date=6 September 1986 |page=21}} 2. ^{{cite news|last1=Sarsfield|first1=Kate|title=Chichester Miles spots new market for Leopard Six jet|url=https://www.flightglobal.com/news/articles/chichester-miles-spots-new-market-for-leopard-six-jet-127619/|accessdate=27 March 2016|work=Flight International|publisher=Flightglobal|date=20 March 2001}} 3. ^{{cite news|title=Obituaries - Ian Chichester-Miles: aircraft designer|url=http://www.thetimes.co.uk/tto/opinion/obituaries/article2086302.ece|accessdate=27 March 2016|work=The Times|publisher=Times Newspapers|date=15 October 2009}} 4. ^{{cite web|title=Chichester-Miles Leopard G-BKRL|url=http://www.aviation-museum.co.uk/index.php?id=17|website=Bournemouth Aviation Museum|accessdate=28 March 2016}} 5. ^{{cite web|title=Latest News|url=http://www.midlandairmuseum.co.uk/news.php?id=24|website=Midland Air Museum|date=12 April 2008|accessdate=28 March 2016}}
