Winter in Finland is cold and windy. If aircraft work here during the winter, they work anywhere, because flying in icing or windy conditions is the ultimate challenge for small UAVs. Fortunately for us, it is easier to apply an efficient anti-icing system to an aircraft which has two propellers than to an aircraft which has eight propellers. Also, when the wind is too heavy for most unmanned vtol aircraft, our tailsitter aircraft can still fly thanks to certain novel structure solutions. It took six years and hundreds of flight hours to get there.
The most important structure solution of our aircraft enables thrust vector control during the flight. We were granted a patent for this structure solution from the United States and the European Union. The competition over these patents is fierce, as many of the industry players are well-known multinational conglomerates such as Airbus, Boeing, Sikorsky and Amazon.
The payload capacity of our standard version aircraft is about 3 kg, which is a third of the weight of the aircraft. Our aircraft is developed to serve households within 12-25 km radius, depending on the payload. With a bigger battery we can reach a maximum range of ~80 km (40 km radius). Efficient cruise speed is ca. 23 m/s (83 km/h).
During these five years we have built several different aircraft prototypes. We can easily modify our current aircraft to suit the needs of our customers: to carry heavier payloads, fly longer range or fly with higher speeds. There are many tricks to achieve this, e.g., using different wing designs, different batteries and so on.
