World Largest Electric Aircraft Completes Historic Maiden Flight in Sweden

Heart Aerospace full-scale electric aircraft demonstrator has successfully completed its first flight test, proving the viability of battery-electric propulsion for regional commercial routes.

Propulsion Breakthrough: Dual Electric Motors and Thermal Management

A historic milestone in green transport was achieved as Heart Aerospace X1 aircraft—the world largest all-electric test plane—successfully completed its 30-minute maiden flight in Gothenburg, Sweden. The 30-passenger capacity demonstrator taxied, took off, and landed smoothly under battery electric power.

The aircraft features four electric motors powered by high-density lithium-sulfur battery packs integrated directly into the wing roots. The system is designed for short-haul regional flights up to 200 kilometers with zero operational carbon emissions.
