Exciting
thing for aviation enthusiasts: A vital step towards electric powered flights
was achieved with the power-up belonging to the world's most powerful amalgam
electric powertrain for aviation at a project led by Pipistrel. Hybrid-electric
powertrains is a new breed of aviation propulsion, which extend to select from
of all-electric aircraft while being non-harmful to the environment and quiet.
The 200 kW propulsor developed within the project HYPSTAIR delivers the force
equivalent to a widespread general aviation piston engine allowing it to run in
three techniques: electric-only mode using battery, generator-only mode or
amalgam mode combining both potential sources.
Pipistrel's
powertrain components were put together by Siemens during the mission and
represent the intuitive of electric flight propulsion. That drive motor,
delivering 200 kW start power and 150 kW uninterrupted, and the generator,
delivering 100 kW have a power density exceeding 5 kW/kg and even dual windings
with four power controllers to make unprecedented reliability. Further part of
innovation is the Human-Machine-Interface which will simplify the operation to
a complex powertrain. A single lever with haptic feedback is commonly employed
to apply power together with a new integrated cockpit display screen to monitor
the powertrain level and performance.
After
the extensive lab testing of components additionally, the integration on a
representative airframe around the Pipistrel aviation factory on Slovenia, the
successful switch on managed all propulsion modes at low and increased powers,
driving a expressly developed five blade cheap rpm, low noise propeller. Tests
of take-off potential were performed using combined output belonging to the
generator driven by a turbonormalised engine additionally, the high-performance
battery custom developed compliment high discharge rates.
Pipistrel
TOP DOG, Ivo Boscarol, says: “We are happy with what HYPSTAIR represents in the
development of electric airline. It demonstrates the chances for general
aviation class aircraft to remain electrically powered and the application
confirms the vision in Pipistrel - we were the best to design a 5 seat
aircraft, the Panthera, and that is alternatively equipped with three or more
different propulsion types: piston core, electric motor or amalgam powertrain.
Project HYPSTAIR represents a major step closer to a hybrid aircraft and a
business for Pipistrel and several other general aviation aircraft brand names.
”
Frank
Anton, Head of e-Aircraft additionally, the initiator of electric airliner
development at Siemens AG: “Siemens is without a doubt developing electric
drive products with highest power-to-weight percentage for aircraft propulsion.
Only with innovation you can easily solve the problems in rising fuel costs,
ascending passenger demand and ascending environmental regulation. Innovations
developed for that HYPSTAIR hybrid-electric powertrain can be instrumental in
making aviation more sustainable in the long term. As electric drives can be
scalable, we can expect that later in life also larger aircraft uses electric
propulsion. The world has grown into electric, whether in oxygen, on land or
within sea. ”
During
next few months, extensive testing will begin to simulate typical mission
profiles covered with the performance study and to help you validate the hybrid
dr concept and performance. This pioneering achievement was initially unveiled
at the E2 Fliegen Symposium 2016 on Stuttgart, Germany.
Interestingly,
HYPSTAIR has received funding belonging to the European Union’s Seventh
Assembly Program for research, complex development and demonstration with grant
agreement no. 605305. Mission partners are Pipistrel h. o. o. Ajdovščina,
Siemens AG, MBVision, Institution of Pisa and Institution of Maribor.
