First test flight of largest all-electric aircraft used just $5 of electricity
摘要
全球最大纯电飞机X1于8月12日在纽约普拉茨堡国际机场完成首飞，飞行近半小时，耗电成本仅约5美元。该机由Heart Aerospace研制，尺寸接近小型支线客机，最大起飞重量超2.5万磅，配备四台翼装电机，首飞时推进系统功率超1兆瓦。纯电飞行更安静、清洁，且不受地缘政治导致的燃油价格波动影响，在成本效益上更具优势。
The first flight of the largest battery-electric aircraft to take to the skies lasted nearly half an hour while costing just $5 of electricity. That aviation feat comes at a time when jet fuel prices have skyrocketed because of the US war with Iran.
The test flight of Heart Aerospace’s X1 demonstrator aircraft took place at Plattsburgh International Airport in upstate New York on August 12. The X1 aircraft is comparable in size to a small regional airliner and can achieve a maximum takeoff weight exceeding 25,000 pounds with the help of four wing-mounted electric motors. The battery-electric propulsion system delivered more than one megawatt of power during the maiden flight.
All-electric aircraft can offer quieter and cleaner flight without the emissions that come from burning jet fuel. They may also prove more reliably cost-effective than conventional aircraft that come with jet fuel costs subject to geopolitical disruptions.
