The Concept Prowler is an American flying wing ultralight trike that was designed and produced by Concept Aviation of Knoxville, Tennessee.[1]

Design and development[edit]

The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 248 lb (112 kg). It features a cable-braced hang glider-style high-wing, weight-shift controls, a single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration.[1]

The Prowler's design goals included maximum cruise speed and to achieve this a wing of small area was selected. This results in an ultralight with a cruise speed of 57 mph (92 km/h), at the expense of a stall speed of 28 mph (45 km/h), the fastest stall speed permitted by FAR 103 category rules.[1][2]

The aircraft is made from bolted-together aluminum tubing, with its double-surface wing covered in Dacron sailcloth. Its 110 sq ft (10 m2) area wing is supported by a single tube-type kingpost and uses an "A" frame control bar. The standard engines supplied was the 40 hp (30 kW) Rotax 447 twin cylinder, two-stroke, air-cooled, single ignition aircraft engine. A cockpit fairing and wheel pants were factory options.[1]
