“Farrington Twinstar”的意思、由来-开放百科全书

The Farrington Twinstar is an American two-seat autogyro that was designed and produced by Farrington Aircraft of Paducah, Kentucky, a company owned by Don Farrington. Now out of production, when it was available the aircraft was supplied as a kit for amateur construction.^[1]

Design and development

The aircraft was designed to comply with the US Experimental - Amateur-built aircraft rules. It features a single main rotor, a two-seats-in tandem open cockpit with a windshield, tricycle landing gear without wheel pants, plus a tail caster. The tail consists of two vertical stabilizers and rudders. The acceptable power range is {{convert|120|to|180|hp|kW|0|abbr=on}} and the standard engine used is a four-cylinder, air-cooled, four-stroke, dual-ignition {{convert|150|hp|kW|0|abbr=on}} Lycoming O-320 in pusher configuration. The cabin width is {{convert|24|in|cm|0|abbr=on}}.^[1]

The aircraft fuselage is made from a combination of welded steel and bolted-together aluminum tubing, with a fiberglass cockpit fairing. Its two-bladed rotor has a diameter of {{convert|30|ft|m|1|abbr=on}}. The aircraft has a typical empty weight of {{convert|700|lb|kg|abbr=on}} and a gross weight of {{convert|1200|lb|kg|abbr=on}}, giving a useful load of {{convert|500|lb|kg|abbr=on}}. With full fuel of {{convert|20|u.s.gal}} the payload for the pilot, passengers and baggage is {{convert|380|lb|kg|abbr=on}}.^[1]

The standard day, sea level, no wind, take off with a {{convert|150|hp|kW|0|abbr=on}} engine is {{convert|200|ft|m|0|abbr=on}} and the landing roll is {{convert|50|ft|m|0|abbr=on}}.^[1]

The manufacturer estimated the construction time from the supplied kit as 200 hours.^[1]

Operational history

By 1998 the company reported that 25 kits had been sold and five aircraft were completed and flying.^[1]

In March 2015 six examples were registered in the United States with the Federal Aviation Administration, although a total of 12 had been registered at one time.^[2]
