It leads to improved resource efficiency, reduction of CO2\u00a0and NOx emissions as well as a\u00a0decrease of the particulate matter. If no actions would be undertaken, the adverse impact of aviation on the environment would significantly grow due to the expected increase of air transport traffic by 5% every year. Improvement of the environmental impact of the aircraft can be achieved for instance through better engine efficiency and advanced combustion technologies, improved aerodynamics or reduction of the weight of an aircraft.\u201d<\/p>\n<p>Perkon concludes that producing a modular powertrain architecture as the basis for future standardization, \u201cwill show that, by funding a small project that is not that expensive, we can extrapolate the results and use them for megawatt aircraft of the future.\u201d<\/p>\n<div id=\"facebook_like\"><iframe src=\"http:\/\/www.facebook.com\/plugins\/like.php?href=http%3A%2F%2Fcafe.foundation%2Fblog%2Fpipistrel-leads-mahepa-european-hybrid-research%2F&amp;layout=standard&amp;show_faces=true&amp;width=500&amp;action=like&amp;font=segoe+ui&amp;colorscheme=light&amp;height=80\" scrolling=\"no\" frameborder=\"0\" style=\"border:none; overflow:hidden; width:500px; height:80px;\" allowTransparency=\"true\"><\/iframe><\/div>","protected":false},"excerpt":{"rendered":"<p>Aviation Week\u2019s Graham Warwick reports, \u201cEurope plans to develop and test modular hybrid-electric propulsion technology using light aircraft as testbeds, but it is also studying whether the system can be scaled up to power 19- and 70-seat commercial aircraft.\u00a0 The MAHEPA Program intends to bring cleaner skies to Europe.
