As with other Rutan designs, the Quickie is constructed of glass fibre and resin over a foam core. The wings are foam blanks cut to shape with a hot wire before covering, and the fuselage made up of 1 inch-thick (25.4 mm) foam slabs. The forward wing provides around 60% of the lift.
The airplane was constructed of fiberglass and resin over a foam core, similar to other Rutan designs; the wings essentially blue styrofoam billets cut to shape with a hot wire, followed by microslurry and resin/fiberglass layup; the fuselage was made up of one inch-thick foam slabs with microslurry and resin/fiberglass layup.
Fuselages are moulded in Kevlar/carbon and epoxy, with wings either moulded as a hollow composite shell, or vacuum bagged over a wire-cut foam core. Most DLG models use aileron, rudder and elevator control, with the ailerons serving as camber changing flaps for different modes of flight and also as airbrakes for landing. A modern DLG model ...
The aircraft is made from pre-preg carbon fibre built on a foam core. Its 8.4 m (27.6 ft) span wing has an area of 9.4 m 2 (101 sq ft) and flaps. Standard engines available are the 100 hp (75 kW) Rotax 912ULS and 912iS, although engines up to 150 hp (112 kW) can be installed. [1] The cabin width for all models is 121 cm (48 in). [3]
The aircraft is made from fiberglass, with the fuselage a fibreglass sandwich and the wings and canard built from fibreglass spars and solid-core fibreglass airfoil shapes cut with a hot-wire foam cutter. Its 23.0 ft (7.0 m) span wing has a wing area of 75.0 sq ft (6.97 m 2). The cabin width is 26 in (66 cm).
The aircraft is constructed from fiberglass on Nomex honeycomb and urethane foam. [ 2 ] [ 3 ] The 41.75 ft (12.7 m) wing has a built-in mid-span twist to offset the effects of the canard's downwash, with the inboard 7.4 ft (2.3 m) having 2 degrees less twist than the outboard portion of the wing.
The density of the foam varies with the type being used; Type 2.5 is a white to light amber foam weighing 2.5 pounds per cubic foot, while Type 1.8 is a pale blue to green foam weighing 1.8 pounds per cubic foot. [3] Chopped fiberglass strands embedded in the foam add to the structural integrity through physical support and shrapnel mitigation.
Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.
