“Spring WS202 Sprint”的意思、由来-开放百科全书

The Spring WS202 Sprint was a Canadian homebuilt aircraft that was designed and produced by William J. Spring of Burlington, Ontario, introduced in 1996. The aircraft was supplied in the form of plans for amateur construction.^[1]^[2]

Design and development

The WS202 Sprint featured a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed tricycle landing gear or conventional landing gear and a single engine in tractor configuration.^[1]

The aircraft was made from sheet aluminum. Its {{convert|27.0|ft|m|1|abbr=on}} span wing, mounted flaps and had a wing area of {{convert|130|sqft|m2|abbr=on}}. The cabin width was {{convert|45|in|cm|abbr=on}}. The design power range was {{convert|65|to|100|hp|kW|0|abbr=on}} and the engine used in the prototype was a {{convert|65|hp|kW|0|abbr=on}} Subaru EA81 automotive conversion powerplant.^[1]

The aircraft was designed to be constructed from plans and emphasized economy. The designer claimed it could be constructed for US$5000 in 1996, including a second hand Subaru engine. It was designed to be easy to convert between tricycle and conventional landing gear.^[1]

The aircraft had a typical empty weight of {{convert|670|lb|kg|abbr=on}} and a gross weight of {{convert|1150|lb|kg|abbr=on}}, giving a useful load of {{convert|480|lb|kg|abbr=on}}. With full fuel of {{convert|14|u.s.gal}} the payload for the pilot, passenger and baggage was {{convert|396|lb|kg|abbr=on}}.^[1]

The standard day, sea level, no wind, take off and landing roll with a {{convert|65|hp|kW|0|abbr=on}} engine was {{convert|500|ft|m|0|abbr=on}}.^[1]

The manufacturer estimated the construction time from the supplied plans as 1500 hours.^[1]

Operational history

By 1998 the designer reported that one aircraft had been completed and was flying.^[1]

In April 2015 one example had been registered with Transport Canada to the designer, William J. Spring, although its registration was cancelled on 13 February 2013.^[2] It is unlikely that the aircraft exists any more.
