摘要

This year saw continued advancements in electric-powered flight. Pipistrel achieved first flight of its WATTsUP electric trainer aircraft in August. The aircraft, which is based on the airframe of the Slovenian company's Alpha Trainer, employs an 85-kilowatt electric motor developed by Siemens that provides more power than the Rotax 912 it replaces, permitting an increase in the rate of climb to 1,000 feet per minute. The aircraft achieves one hour of endurance with a 30-minute visual flight rules reserve. On approach, up to 13 percent of the energy expended in the pattern climb and circle can be recovered from the windmilling propeller. The three batteries can be removed and exchanged or recharged to 80 percent capacity in less than an hour to enable rapid sorties. The aircraft has been certified in France and preparations are being made for U.S. certification through revised light sport aircraft standards that permit electric motor propulsion. Priced at $125,000, sales are set to begin in 2015.
