“Collins Dipper”的意思、由来-开放百科全书

The Collins Dipper was an American homebuilt flying boat that was designed and produced by Collins Aero of Chadds Ford, Pennsylvania and first flown in 1982. The aircraft was supplied in the form of plans for amateur construction. Only one was built and none remain registered.^[1]^[2]

Design and development

The Dipper was a conversion of a Cessna 150, adding a fiberglass hull and nose to the Cessna land plane. Development was protracted and started in 1964, leading to a first flight in 1982.^[1]

The Dipper featured a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit with doors, retractable tricycle landing gear and a single engine in pusher configuration mounted above the cabin on struts.^[1]

The aircraft is made from aluminum and fiberglass, retaining the Cessna 150's wing and lift struts. The {{convert|33.4|ft|m|1|abbr=on}} span wing employs a NACA 2412 airfoil, mounts flaps and has a wing area of {{convert|160|sqft|m2|abbr=on}}. The standard engine used was the {{convert|180|hp|kW|0|abbr=on}} Lycoming O-360 powerplant.^[1]^[3]

The aircraft nose wheel retracted forward and the main landing gear retracted upwards into the rear window space.^[1]

The Dipper had a typical empty weight of {{convert|1100|lb|kg|abbr=on}} and a gross weight of {{convert|1760|lb|kg|abbr=on}}, giving a useful load of {{convert|660|lb|kg|abbr=on}}. With full fuel of {{convert|39|u.s.gal}} the payload for pilot, passengers and baggage is {{convert|426|lb|kg|abbr=on}}.^[1]

The manufacturer estimated the conversion time from the plans as 1000 hours.^[1]

Operational history

In 1998 the company reported that 13 sets of plans had been sold and one aircraft was flying.^[1]

By December 2013 no examples remained registered in the United States with the Federal Aviation Administration.^[2]
