The Shark.Aero Shark is a conventionally laid out, single engine, low wing light aircraft which seats two in tandem. Designed and built in Slovakia, it offers a choice between fixed and retractable tricycle gear.

Design and development[edit]

The Shark, which was formally announced at the Aero '07 show at Friedrichshafen in April 2007, was designed to fit into both European UL and US LSA categories. Structurally it is a mixture of glass- and carbon-fibre composites, with PVC foam filled aramid honeycomb structures sandwiched between panels. The wing main spar is a dismountable two piece carbon fibre beam which joins under the front seat; an auxiliary spar carries the aileron and flap mountings. In plan the leading edge is elliptical and there is slight taper on the outer trailing edge where the ailerons are mounted. Single slotted, electrically operated flaps occupy the rest of the trailing edge. Like the wings, the slightly swept tailplanes are easily detached for storage of transport. There is an electrically operated trim tab in the elevator.[1]

It uses a new carbonfiber material called Textreme from the Swedish manufacturer Oxeon.

The fuselage of the Shark is formed with integral fin, seat backs, floors and instrument panel. The fin, set forward so the rudder trailing edge is above the elevator hinge line, is shaped like a shark's, strongly swept and with a curved leading edge. There is also a small ventral fin. From the fin forward the upper fuselage line rises rapidly to merge into that of the side hinged, single piece canopy. There is a baggage space behind the cockpit. Both of the tandem seats have controls; the Shark is flown by sidesticks. It is powered by a 73.5 kW (98.6 hp) Rotax 912ULS driving a three-blade propeller. The Shark LS version has a fixed tricycle undercarriage and fixed pitch airscrew but the retractable gear Shark UL has a variable-pitch propeller.[1]

The prototype Shark LS, Czech registered as OK-OUR01, first flew on 19 August 2009. The first flight of the UL was expected early in 2010 but had not happened by January 2011.[1]

Operational history[edit]

The third Shark was registered in France as F-JSOR in early 2011[2] but was destroyed due to pilot error whilst competing in the Paris-Madrid air race on 26 June 2011.[3] A fourth appears on the Czech register,[4] flying as a demonstrator in Germany.[5]
