“Parascender Para-Ag”的意思、由来-开放百科全书

The Parascender Para-Ag is an American powered parachute agricultural aircraft that was designed and produced by Parascender Technologies of Kissimmee, Florida. Now out of production, when it was available the aircraft was supplied as a kit for amateur construction.^[1]^[2]

Design and development

A variant of the Parascender I, the Para-Ag was designed to comply with the US Experimental - Amateur-built aircraft rules. It features a {{convert|520|sqft|m2|abbr=on}} parachute-style wing, single-place accommodation, tricycle landing gear and a single {{convert|50|hp|kW|0|abbr=on}} Rotax 503 engine in pusher configuration. A {{convert|620|sqft|m2|abbr=on}} wing was optional.^[1]^[2]

The aircraft carriage is built from bolted aluminium tubing. Inflight steering is accomplished via foot pedals that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has foot-controlled nosewheel steering. The main landing gear incorporates spring rod suspension. The aircraft has a typical empty weight of {{convert|285|lb|kg|abbr=on}} and a gross weight of {{convert|720|lb|kg|abbr=on}}, giving a useful load of {{convert|435|lb|kg|abbr=on}}. With full fuel of {{convert|10|u.s.gal}} the payload for the pilot and chemicals for application is {{convert|375|lb|kg|abbr=on}}. A series of dry chemical hoppers and liquid chemical tanks of {{convert|35|to|50|u.s.gal}} were available and the chemicals were disbursed from booms protruding from either side of the cockpit at propeller hub height.^[1]

The standard day, sea level, no wind, takeoff with a {{convert|50|hp|kW|0|abbr=on}} engine is {{convert|150|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 30 hours.^[1]

Operational history

In April 2015 no examples were registered in the United States with the Federal Aviation Administration.^[3]
