This consists of an 80kw\u00a0electric motor with the propeller in front and three low-temperature hydrogen fuel cells behind. The hydrogen is carried in two high-pressure tanks made of carbon fiber, located in each of the two fuselages just aft of the passenger cabin. HY4, as a technology demonstrator, can fly at a cruising speed of 145km\/h and maximum speed of approximately 200km\/h. Its range varies from 750km to 1,500km, depending on the speed, load and altitude parameters.\u00a0The empty weight of HY4\u00a0without the fuel cell, battery and storage system is approximately 630kg, whereas the maximum weight is 1,500kg.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"480\" src=\"https:\/\/news.e-flight-journal.com\/wp-content\/uploads\/2022\/05\/image-6.png\" alt=\"\" class=\"wp-image-784\" srcset=\"https:\/\/www.e-flight-journal.com\/wp-content\/uploads\/2022\/05\/image-6.png 640w, https:\/\/www.e-flight-journal.com\/wp-content\/uploads\/2022\/05\/image-6-300x225.png 300w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"480\" src=\"https:\/\/news.e-flight-journal.com\/wp-content\/uploads\/2022\/05\/image-7.png\" alt=\"\" class=\"wp-image-785\" srcset=\"https:\/\/www.e-flight-journal.com\/wp-content\/uploads\/2022\/05\/image-7.png 640w, https:\/\/www.e-flight-journal.com\/wp-content\/uploads\/2022\/05\/image-7-300x225.png 300w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>With the success of HY4, the team aimed more ambitious goals.
