Design and development
The PW-2 was designed as a lightweight glider of modest performance with an open cockpit. The aircraft was intended to be produced as both a completed aircraft and as a kit for amateur construction.[1]
The aircraft is made from composite material, with its control surfaces covered in doped aircraft fabric covering. Its 11.0 m (36.1 ft) span wing employs an American-designed NACA 4415 airfoil. The maximum glide ratio is 16:1 at 69 km/h (43 mph)[1][3]
Operational history
In August 2011 five PW-2Ds were registered in the United States with the Federal Aviation Administration. All were in the Experimental - Exhibition/Racing category and all produced in 1992 or 1993.[2]
