A British company, Droneliner, is introducing an ambitious plan for cargo drones designed to revolutionize freight transportation. These drones are equipped with "hybrid turbofan" engines, capable of using sustainable aviation fuel (SAF) and hydrogen. Droneliner is unveiling two models: the DL 200, with a 200-ton payload capacity, and the DL 350, boasting an impressive 350-ton capacity, both capable of covering distances of up to 6,500 nautical miles. The larger variant, the DL 350, boasts a substantial all-up weight of 600 tons.
Droneliner's vision aims to reduce airfreight costs by over 70%, making them comparable to sea freight costs, while simultaneously reducing delivery times and emissions. The DL 200 can accommodate more than 40 standard 20-foot shipping containers across two levels, while the DL 350 offers an astounding 80 containers over three levels. These cargo drones are remotely piloted, eliminating the need for onboard crew and accommodations, resulting in significant cost savings. Droneliner's unique double trussed airfoil design boasts ultra-low drag for enhanced efficiency.
While Droneliner has not disclosed specific costs or the necessary ground infrastructure for these massive cargo airframes, their proposal represents a significant step forward in sustainable and cost-effective freight transport.
