Project DragonFly

Project DragonFly



The Aeronautical Engineering department at Inholland University of Applied Sciences in Delft started a project in 2019 to get this Dragonfly in the air. The goal is to utilise new technologies which currently are still in development by the industry together with research institutes to significantly lower the emission for aviation. Project DragonFly is aiming to fly using electric propulsion with solar charged batteries. Solar-cells on the skin of an airplane? Yes, this seems far fetched, but the automotive industry is currently innovating rapidly to get this integrated in the mobility sector. Although the first milestone will not include solar cells yet, this will be made part of the longer term goals at Inholland.

The Viking Dragonfly MK.II is an American amateur-built aircraft, designed by Bob Walters and produced by Viking Aircraft LLC of Elkhorn, Wisconsin. This aircraft was originally supplied as a kit for amateur construction. The Aviodrome in Lelystad got hold of a Dragonfly a long time ago as the original Dutch owner Mr. Thom Sijs agreed to store it at the museum, waiting for final assembly at a later stage. Now, many years later, it was decided that the Aeronautical Engineering faculty at the Inholland University of Applied Sciences would be a much better place to facilitate finalisation of the construction.

On March 20, 2019, the Dragonfly was transported from the Aviodrome to Inholland in Delft where several students prepared the arrival at Inholland Composites. The plan is to restore the airplane as much as possible and use it for the curriculum for the upcoming Aeronautical Engineers.

The Dragonfly is a two-seater aircraft that features a tandem wing layout with a forward wing mounted low and the other behind the cockpit in a shoulder position, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed landing gear and a single engine in tractor configuration. The cockpit is 109 cm wide[

The aircraft is constructed from composites, based on construction techniques pioneered by Burt Rutan at Rutan Aircraft Factory (RAF). The airframe design is visually similar to the RAF’s Quickie 2, which was developed independently, but the Dragonfly has larger airfoils and a smaller engine, resulting in a slower but more docile handling aircraft. Its forward 20 ft (6.1 m) span wing employs a GU25-5(11)8 mod airfoil, when the aft wing (span 22 ft) uses an Eppler 1212 airfoil. Both wings have a total area of 92.2 sq ft (8.57 m2). Standard engines used include the 60 hp (45 kW) Volkswagen air-cooled engine and the 85 hp (63 kW) Jabiru 2200four-stroke powerplants. Construction time from the supplied kit is estimated as 700 hours, while from plans is estimated at over 1200 hours. The Dragonfly was given the Outstanding New Design Award at the EAA Convention in 1980.[5] By 1998, 500 examples of all variants were reported as flying
