A team of engineers from the National Aeronautics and Space Administration (NASA) has successfully developed a small, unmanned drone that can mimic the flight of birds, utilizing free energy in the atmosphere to soar through the skies.
By employing this method, the drone can conserve fuel and extend its flying range. The robotic aircraft can detect and harness rising warm air currents to ascend like a glider. During this process, the engine automatically shuts off, allowing the drone to glide and maintain altitude thanks to the lifting force of the warm air currents. NASA hopes this discovery paves the way for advancements in technology that utilize rising warm air currents to extend the flying range of unmanned aircraft, which often face fuel limitations.
