an unmanned aerial surveillance aircraft that uses the gas engine for the flight to a targeted area, then switches over to the much quieter battery in order to be

more stealthy, or extend its range, writes Richard Pat Anderson, professor. Illustration: mckibillo Smil Says An all-electric intercontinental jetliner would need batteries whose energy density is three orders of magnitude higher than todays best designs. It isnt clear just how these numbers are to be calculated. In any case, nasa estimates that passenger planes using cryogenic systems of 30 MW and up wont be ready to fly until the mid-2030s. In 2016, 23 countries agreed to limit the carbon emissions of their commercial aircraft beginning in 2020, according to standards set by the International Civil Aviation Organization (icao an agency of the United Nations. A kilo saved on the motor gives you precious extra kilos for the batteries. As a megawatt of electric power is equivalent to 1,341hp, the F110 still has plenty of thrust to continue powering even in a single-engined aircraft. This allows customers to transfer risk and cost to GE, while working to minimise both at hybrid entry into service, the document says. An electric motor and petrol engine work together to drive the propeller. Progress on GE Aviations major research project in hybrid electric propulsion has been released. According to nasa Langley Aeronautic Systems Analysis Branch engineer Jason Welstead, this translates into 7 and 12 block fuel-burn savings for the economic and design missions, respectively. Because it is relatively easy to transmit power electrically to multiple widely spaced motors, turboelectric and other electric propulsion concepts are well-suited to distributed propulsion for higher bypass ratios, and they provide aircraft design options for maximizing the benefits of boundary layer ingestion (BLI). By taking advantage of both electric motor and internal combustion engine, hybrid-electric propulsion systems provide not only a benefit in fuel saving but also a reduction in takeoff noise and the emission levels. Researchers from the University of Cambridge, in association with Boeing, have successfully tested the first aircraft to be powered by a parallel hybrid-electric system. And second, the power density of the motor and the engine-generator system that runs it must also. We are gaining experience with the complete system of electric propulsion, with everything thats between the pilot and the propeller, says Frank Anton, head of Siemenss eAircraft department. Developed and fabricated by Aurora Flight Sciences, the revolutionary aircraft includes 24 electric ducted fans18 distributed within the main wings and six in the canard surfaces, with the wings and canards tilting upwards for vertical flight and rotating to a horizontal position for wing-borne flight. Siemens will deliver the 2MW electric motors and their power electronic control unit, as well as the inverter, DC/DC converter, and power distribution system. It wants less fuel being Boeing 737-size hybrid turbo-electric diverted to these systems. While electric propulsion is more efficient, but it generates far less thrust, which is why electric planes tend to be slow. Other companies are also on the hunt. The big improvement will come after experience and economies of scale with hybrids allow the industry to make the transition to pure-electric planes, perhaps in the 2030s. At the Budapest research center, Bal√°zs walks me over to a lab bench, where he hands me part of a motor thats been cut in half. Siemens itself is working with. The greatest limitation to using battery-powered aircraft is weight. . But the most striking feature of all is the power and propulsion system of the aircraft. The Starc-ABL (single-aisle turbo-electric aircraft with an aft boundary layer propulsor) is the new test proposal that builds upon previous N3-X team hybrid designs and Boeings concepts for turbo-electric airlinersresearch done under the joint Boeing-nasa venture the Sugar Program. For although todays lithium-ion batteriesracks of which are stowed just ahead of the cockpitstore far more energy than they could just a few years ago, they cant come close to a tank of gasoline. A solar-powered plane that completed an around-the-world journey this summer had an average airspeed of 47 miles per hour. Meanwhile, Boeing has teamed up with JetBlue Technology Ventures to fund Zunum Aero, which is designing a hybrid-electric business aircraft and 50-seat regional jet to fly in the early 2020s. It originally planned to put superconducting motors aboard ships at sea, where space and weight are at a premium.

And its, a turbogenerator a gas turbine driving an electrical generator is grover c gilmore phd coupled to a bank of batteries. Hybrids burn fuel, s As part of the EFan X programme. Hybrid technology is not new to the aviation industry.

A light plane modified by Siemens to run purely on electricity. In the paper future, this is the fully aerobatic version of the Extra 330LE. The propeller immediately spins into transparency. And this tells us how the power distribution will work. Hybrid passenger aircraft that combine electric and combustion power trains will begin serving in short and mediumhaul routes. Just a picture of the bigger supercooled machine with a diagram of the future aviation version superimposed.

The programme also aims to establish the requirements for future certification of electrically powered aircraft while training a new generation of designers and engineers to bring hybrid-electric commercial aircraft one step closer to reality.They save energy because theyre lighter and more efficient.
