Diamond Aircraft’s DART-450 made its public debut this week at the U.K.’s Farnborough International Airshow. The single-engine turboprop first flew in May at Diamond’s facility in Austria, less than a year after initial design work began. Like Diamond’s other aircraft, such as the DA42, the DART (Diamond Aircraft Reconnaissance Trainer) will offer versatility, with potential uses including training and surveillance operations, and efficiency with a fuel burn of about 90 liters (24 gallons) per hour.

The airplane is built from carbon fiber in a low-wing, tandem two-seat configuration. It is fully aerobatic up to +7/-4Gs and has maximum takeoff power of 495 horsepower with a Ukrainian Ivchenko-Progress Motor Sich AI-450S turboprop and a five-blade MT propeller. It’s also equipped with ejection seats, Garmin avionics and a fuselage that is ready-to-mount for a retractable surveillance camera and other equipment. Diamond first announced the new model at the 2014 show, saying it planned to fly a prototype at this year’s event.

Maiden flight of the Diamond Aircraft DART-450

On May 17, 2016 the turbine powered DART-450 took off for its first flight.

The DART-450 (Diamond Aircraft Reconnaissance Trainer) is the world’s first all-carbon fiber tandem, 2-seat aerobati civilian and military trainer with sidestick control and ejection seats.

The +7/-4G aerobatic airplane has a maximum take-off power of 500 hp, is equipped with the Ivchenko-Progress / Motor Sich AI-450S turboprop engine, a 5-blade MT propeller, and a GARMIN avionic system. Maximum endurance of the DART is 8 hours plus reserve.

Within the first 60 minutes of flight time, speeds between 60 – 200 knots IAS have been tested at various altitudes. Expected top speed is 250 knots TAS.

“Company Chief Test Pilot Ingmar Mayerbuch and Flight Test Engineer Thomas Wimmer have been so excited about the first results that certification and serial production is green-lighted”, said Christian Dries, CEO Diamond Aircraft.

Diamond Aircraft Chief Designer Clemens Knappert: “We achieved our target from the first drawings to the first flight in one year. I’m already excited about what comes next.”
