HY4 aircraft appears to be based on Pipistrel Aircraft’s (Ajdovščina, Slovenia) innovative Taurus
G4, which married two of the company’s electric gliders into a twin-boom platform with a single electric motor in the center section wing. The
G4 won the $1.35 million NASA Green Flight Challenge award in 2011.
According to Bertorelli’s article, project leader Josef Kallo describes the
HY4 as a sixth-generation hydrogen drive that uses a fuel cell to power a single 160-hp electric motor for a top speed of 108 knots and range of up to 900 miles. Test flights began in November and more than 30 takeoffs and flights of up to two hours have been completed.
