Lancair Evolution

From Wikipedia, the free encyclopedia

The Lancair Evolution is an American pressurized, low wing, four-place, single engine light aircraft, made from carbon fiber composite, developed by Lancair and available as an amateur-built kit.[1][2][3]

The Evolution can be powered by a Lycoming TEO-540-A piston engine or a Pratt & Whitney PT6-135A turboprop powerplant.[1][2][3][4][5]

Development

The Evolution was designed to meet the same FAR Part 23 aircraft certification standards that type certified aircraft comply with. The kit includes energy absorbing seats.[2]

The aircraft is pressurized and was designed for a 6.5 psi (0.45 bar) differential pressure, giving an 8,000 ft (2,438 m) cabin pressure at its maximum altitude of 28,000 ft (8,534 m).[6]

The turbine version of the Evolution is powered by the 750 hp (559 kW) Pratt & Whitney PT6A-135A and has a maximum cruise of 300 kn (556 km/h) at 25,000 ft (7,620 m) on a fuel burn of 39 US gal (148 l) per hour of Jet-A. Cruising at an economy cruise of 270 kn (500 km/h) at 28,000 ft (8,534 m) it burns 23 US gal (87 l) per hour. It has a full-fuel payload of 837 lb (380 kg) and a 61 kn (113 km/h) flaps-down stall speed.[5]

The piston version is powered by a Lycoming TEO-540-A2A engine and has a maximum cruising speed of 270 kn (500 km/h) on a fuel burn of 22 US gal (83 l) per hour of Avgas. At an economy cruise speed of 240 kn (444 km/h) the fuel flow is 17.5 US gal (66 l) per hour. It has a full-fuel payload of 773 lb (351 kg) and a 61 kn (113 km/h) flaps-down stall speed.[4]

The first customer kit was delivered on 22 July 2008 and production was planned at that time for two kits per month.[7] By December 2011 one piston model and 15 turbine models had been completed and flown. Construction time from the supplied kit is estimated as 1000 hours.[1]
