Electric aircraft development
In 2007, an electric version of the Taurus was released, the world's first 2-seat fully electric aircraft and the first electric motor-glider to achieve serial production.[15] In 2008, Popular Science magazine listed Taurus Electro among Ten Best Innovations of the year in the Aviation&Space category.[23]
The Taurus G4, developed in 2011, was the first all-electric four-seat aircraft.[24] It used the most powerful electric motor in an all-electric airplane design at that time.[25] In July 2015, Siemens, provider of the Dynadyn 60 kW motor used in the Alpha Electro trainer, warned Pipistrel that it should not use its motors for overwater flights, just as Pipistrel was about to launch a historic electric-powered flight across the English Channel and back. As it turns out, Airbus was preparing exactly the same Louis Blériot-like exploit, with a plane powered by a motor also provided by Siemens, and it was speculated that Siemens was pressured by Airbus.[26][27]
In February 2016, Pipistrel ran the most powerful hybrid electric powertrain in aviation to date, as a part of the project HYPSTAIR.[28][29] The EU funded the Hypstair program: a Pipistrel Panthera mockup received a serial hybrid-electric powertrain, ground testing a 200 kW motor driven by batteries only, by a 100 kW generator-only and by both combined. The Hypstair program is followed by Mahepa project from 2017, EU-funded over four years. Panthera ground testing is planned for 2019 before flight tests in 2020.
On 29 September 2016, the world's first four-seat passenger aircraft powered by a zero-emission hydrogen fuel cell propulsion system accomplished a successful first public flight. Pipistrel was one of the partners in the "HY4" project.[30][31] The dual-fuselage, battery-powered Taurus G4 received a DLR hydrogen fuel cell powertrain to fly as the HY4, with hydrogen tanks and batteries in the fuselages, fuel cells and motor in the central nacelle. Partners are German motor and inverter developer Compact Dynamics, Ulm University, TU Delft, Politecnico di Milano and University of Maribor. Ground and flight tests should follow those of the hybrid Panthera a couple of months later.[32] The HY4 flew in April 2022.[33]
In June 2019, the company had formed a new R&D sister company, "Pipistrel Vertical Solutions," to develop the Pipistrel 801 electric VTOL aircraft.[34]
On 10 June 2020, the Pipistrel Velis Electro, the fully-electric version of the Virus SW 121, received the World's first type certificate for an electric aircraft from EASA.[35]
On 1 September 2020, the company introduced two cargo carrying electric drones, the Pipistrel Nuuva V300 and the smaller Pipistrel Nuuva V20.[36]
Pipistrel is planning a liquid hydrogen fuel cell and battery-powered 19-seat hybrid “Miniliner” for a project launch in 2021, a first flight in 2028, and service entry in 2030 or 2031. A 8,500-9,000 kg (18,700-19,800 lb) maximum take-off weight, slightly above the hopefully relaxed 8,618 kg EASA CS-23 limit, would allow a 1,000 nmi range. Batteries would be used for short takeoffs, down to 800 m (2,620 ft), with 2 MW of installed power. It would use technology from EU-funded MAHEPA and UNIFIER19 programmes, and three different configurations are evaluated while the composite wing and fuselage are fixed. Pipistrel targets a 1,500 aircraft market and 40% lower operating costs than current commuter aircraft.[37]
