Quieter, more efficient, more flexible: The company Flargo seeks to enter market segments where helicopters have been predominantly used, with an innovative heavy-cargo drone. The goal is to offer significant advantages over helicopters. To tackle existing challenges with range, the German-Lithuanian startup is not relying on advancements in battery technology but instead exploring innovative solutions in aerodynamics and mechanics.

Internationally connected industries, „just-in-time“ logistics, and increased demands for more resilient supply chains have led to an unprecedented high in the demand for fast, reliable, and cost-effective transport options. Price pressures, ecological imperatives, and complex international relations have prompted a reassessment of traditional transport routes, and the growing shortage of personnel has further unsettled past certainties. As a result, gaps are increasingly emerging, especially in the last and second-to-last mile of local and regional goods transport, which unmanned systems could potentially fill. However, it’s important to note that they could close these gaps; so far, the UAS industry has yet to deliver the revolution in the logistics sector that many have hoped for and some have promised.

Physical challenges

Apart from regulatory and economic challenges in individual goods delivery – think „pizza drone“ – it is primarily the physical and structural challenges that currently make it impossible for purely electric drones to transport heavy loads over long distances. Their real-world operational capabilities are limited by constraints on energy density, the enormous power requirements during hover, and, consequently, the restriction of payloads to relatively light cargo in short-range applications. As a result, battery-electric systems can only reach destinations within a radius of about 40 kilometers.
