The Hermanspann Chinook is an American mid-wing, two-seat, experimental research glider that was designed and constructed by Fred Hermanspann and Art Penz.[1][2]

Design and development

The Chinook and its improved variant, the Chinook S, have been used to study the effect of rain on airfoils and also stall dynamics.[1]

The aircraft is predominantly made from aluminium with the cockpit area made from fiberglass. Its Шаблон:Convert span high aspect ratio wing employs a Wortmann FX67-K-170/17 airfoil. Glidepath control is via hydraulically operated trailing edge flaps that deflect 80°. The landing gear consists of hydraulically retractable nose gear and main gear. The vertical stabilizer is highly swept.[1][3]

The improved Chinook S features an improved wing tip design, system and structure refinements and a BRS-1200 ballistic parachute.Шаблон:Citation needed

Only one Chinook was constructed and it was registered with the US Federal Aviation Administration in the Experimental - Amateur-built category.[1][2]

Operational history

In March 2015 the Chinook was still registered with the FAA to Hermanspann.[2]

After the conclusion of a number of research projects including about rain effects, performance measurements and stall dynamics, the sailplane was being employed extensively through 2015 for cross-country flying, having made a total of five crossings of the Cacscade mountains and having set four Washington state soaring records.Шаблон:Citation needed
