“Midwest Questar Open Aire”的意思、由来-开放百科全书

The Midwest Questar Open Aire is an American ultralight aircraft that was designed and produced by Midwest Engineering of Overland Park, Kansas. When it was available the aircraft was supplied in the form of plans for amateur construction, but the plans were withdrawn on 29 June 2000.^[1]^[2]

Design and development

The Questar Open Aire was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of {{convert|254|lb|kg|0|abbr=on}}. The aircraft has a standard empty weight of {{convert|220|lb|kg|0|abbr=on}}.^[1]

The aircraft features a strut-braced high-wing, a single-seat open cockpit without a windshield, fixed conventional landing gear without wheel pants and a single engine in pusher configuration.^[1]

The Questar Open Aire is made from bolted-together aluminum tubing and wood, with its flying surfaces covered in doped aircraft fabric. Its {{convert|28.66|ft|m|1|abbr=on}} span wing has a wing area of {{convert|124.0|sqft|m2|abbr=on}} and is supported by "V" struts. The acceptable power range is {{convert|30|to|40|hp|kW|0|abbr=on}} and the standard engines used are small {{convert|30|hp|kW|0|abbr=on}} two-stroke powerplants.^[1]

The aircraft has a typical empty weight of {{convert|220|lb|kg|abbr=on}} and a gross weight of {{convert|450|lb|kg|abbr=on}}, giving a useful load of {{convert|230|lb|kg|abbr=on}}. With full fuel of {{convert|3|u.s.gal}} the payload for the pilot and baggage is {{convert|212|lb|kg|abbr=on}}.^[1]

The standard day, sea level, no wind, take off and landing roll with a {{convert|30|hp|kW|0|abbr=on}} engine is {{convert|100|ft|m|0|abbr=on}}.^[1]

Operational history

By 1998 the company reported that 50 sets of plans had been sold and that ten aircraft were completed and flying.^[1]
