Diamond DART-450 / TA-20 Trainer

The DART-450 (Diamond Aircraft Reconnaissance Trainer), being developed by Austrian-based Diamond Aircraft Industries, is the world’s first all-carbon fibre, tandem twin-seat civil and military trainer.

The design of DART-450 was unveiled at the Aero Friedrichshafen 2015. The first DART-450 prototype aircraft made its first flight in May 2016. The successful flight test paved the way for the certification process, scheduled for completion by the end of 2016.

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.” Source diamond-air.at

The aircraft will be displayed at the Farnborough International Airshow to be held in July 2016 and is expected to enter service in 2017.

The aircraft is primarily intended for pilot training, acrobatics and reconnaissance missions. It is expected to offer low-cost competition to existing trainer aircraft in its class.


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. Source avweb.com

The Dart 450 single-engined turboprops on display in the company’s static exhibit are the first of two examples built so far, with chief executive Christian Dries expecting a third to make its debut flight before the end of the year. The lead pair are powered by the Ivchenko-Progress/Motor Sich AI-450S engine while the latest aircraft will use a GE Aviation engine with a 550hp (410kW) output.

The Austrian airframer will deliver its first Dart 450 to an undisclosed buyer shortly in a non-certificated kit version, and plans to hand over the first fully certificated aircraft in 2018.

The tandem-seat aircraft is developed as a civilian and military trainer, and with an endurance of up to 8.5h, Dries also sees a role for the Dart 450 in the surveillance and reconnaissance markets. “We have had so much interest in this product,” he says. “We expect it to be Diamond’s most successful model ever.”

Production of about 50 aircraft a year is planned at the airframer’s Weiner Neustadt facility. Source flightglobal.com

Chinese Company Buys Rest Of Diamond: Here


Austrian-based Diamond Aircraft Group has been acquired by the Chinese company that purchased Diamond’s North American operations last year. Almost a year to the day that Wanfeng Aviation Industry Co. Ltd. bought Diamond’s London, Ontario, plant, the Chinese firm bought the Austrian holdings of sole shareholder Christian Dries, who founded Diamond 25 years ago. Wanfeng said in a joint announcement it intends to increase production and sales, expand distribution and support networks and keep designing new aircraft.

Cockpit and avionics

The DART-450 trainer accommodates two crew members in tandem configuration. The bubble glass canopy on the cockpit offers improved visibility and access for crew.

The cockpit is also installed with Garmin avionics suite, which includes high-resolution, primary flight displays (PFDs) and multi-functional displays (MFDs).

The cockpit is equipped with side-stick control and ejection seats. The side-stick will initially be mated to conventionally boosted flight controls, before being integrated into a fly-by-wire system when designed.

Buyers will be offered a Garmin G3000-equipped cockpit as standard, or can select a system from other suppliers, including Esterline, Dries says. The Dart features a sidestick controller, while customers have the option to select Martin-Baker Mk16 ejection seats or a pneumatic escape system from Zvezda. Source flightglobal.com

GE H-75? (Third aircraft)

The GE H-Series is a family of turboprop engines o ering a customized range of ratings and performance for commuters, personal and agricultural aircrafts and aerobatic trainers.

The engine is a two-shaft, reverse ow design featuring an axial-centrifugal compressor, an annular combustor with slinger ring fuel distributor and a single high pressure turbine stage. The slinger ring combustor architecture simpli es maintenance and eliminates the need for recurrent fuel nozzle inspections. The propulsion section is powered by a single-stage turbine driving a two-stage planetary gearbox.

GE H-Series is available with either hydromechanical control or rst-in-class Electronic Engine and Propeller Control (EEPC). The EEPC system reduces pilot workload by simplifying engine operation with a single lever power control.

GE H-Series aerobatic engine is equipped with EEPC, multi attitude lubrication system and strengthened structure for high g-force aerobatic maneuvers.
