“Bede BD-12”的意思、由来-开放百科全书

The Bede BD-12 was an American homebuilt aircraft designed by Jim Bede and produced by Bede Aircraft of Medina, Ohio, introduced in the 1990s. The aircraft was intended to be supplied as a kit for amateur construction, but only one was ever built.^[1]^[2]

Design and development

Designed as a scaled-up Bede BD-5, the BD-12 featured a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a gull-wing canopy, retractable tricycle landing gear and a single engine in pusher configuration.^[1]

The aircraft was made from fibre-reinforced plastic composite materials. Its {{convert|23.0|ft|m|1|abbr=on}} span wing, mounted flaps and had a wing area of {{convert|93.0|sqft|m2|abbr=on}}. The standard engines used were the {{convert|100|hp|kW|0|abbr=on}} Continental O-200A or the {{convert|150|hp|kW|0|abbr=on}} Lycoming O-320 powerplant.^[1]

The aircraft had a typical empty weight of {{convert|680|lb|kg|abbr=on}} and a gross weight of {{convert|1310|lb|kg|abbr=on}}, giving a useful load of {{convert|630|lb|kg|abbr=on}}. With full fuel of {{convert|37|u.s.gal}} the payload for the pilot, passenger and baggage was {{convert|408|lb|kg|abbr=on}}.^[1]

The standard day, sea level, no wind, takeoff with a {{convert|150|hp|kW|0|abbr=on}} engine was {{convert|725|ft|m|0|abbr=on}} and the landing roll was {{convert|800|ft|m|0|abbr=on}}.^[1]

The company that currently owns the rights to the design, BedeCorp, indicates that production was not started due to the cost of tooling and the lack of funds.^[2]

The design was further developed into the Bede BD-14, a four-seat version.^[1]^[2]

Operational history

In April 2015 no examples were registered in the United States with the Federal Aviation Administration, although one had been registered to the designer at one time.^[3] It is likely that no examples exist any more.
