SynopsisAlteon is developing autonomous dynamic-soaring aircraft that harvest energy from wind gradients, similar to how albatrosses fly. Its next phase of testing will focus on using wind energy to sustain flight without propulsion.Bengaluru-based aerospace startup Alteon has raised $2.5 million in a round led by Lachy Groom, with participation from Together Fund.The funding comes after the startup successfully demonstrated an aircraft flying autonomously in multiple consecutive loops less than a metre above the open ocean.Alteon is developing autonomous dynamic-soaring aircraft that harvest energy from wind gradients, similar to how albatrosses fly.
