“Harris Geodetic LW 108”的意思、由来-开放百科全书

The Harris Geodetic LW 108 is an American homebuilt aircraft that was designed by J. Warren Harris of Vernal, Utah and made available in the form of plans for amateur construction.^[1]

Design and development

The aircraft features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed landing gear and a single engine in tractor configuration.^[1]

The aircraft is made from spruce and plywood, with the fuselage a geodetic airframe structure, producing a strong, lightweight and low-drag shape. Its wing has a span of {{convert|28.1|ft|m|1|abbr=on}}. The standard engine recommended was the {{convert|80|hp|kW|0|abbr=on}} Continental A80.^[1]

The aircraft has an empty weight of {{convert|585|lb|kg|abbr=on}} and a gross weight of {{convert|1000|lb|kg|abbr=on}}, giving a useful load of {{convert|415|lb|kg|abbr=on}}. With full fuel of {{convert|16|u.s.gal}} the payload is {{convert|319|lb|kg|abbr=on}}.^[1]

Operational history

By October 2013 no examples remained registered in the United States with the Federal Aviation Administration and it is possible that none exist any more.^[2]
