Once airflow becomes turbulent, drag rises sharply, increasing fuel consumption and reducing endurance.<\/p>\n\n\n\n<p>Maintaining laminar flow across large sections of an aircraft is technically difficult because even small surface imperfections, gaps or protrusions can disrupt airflow.<\/p>\n\n\n\n<p>The aircraft seen in the flight-test footage was designed around that principle from the outset.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"571\"
