The German company e-volo has just introduced the Volocopter V200, a helicopter with 18 independent motors and other so many propellers being able to carry two passengers with a maximum weight of 450 kg.
The Volocopter V200 feeds on two batteries that give it a flight endurance of 20 minutes ideal for small errands like fetching bread on Sundays. Although it looks a little weird, I can assure that the V200 a success design if we take into account the previous version, equipped with 16 engines and whose image you can see below.
It seems that e-volo left the line of design inspired by the kitchen grinders to focus on a more traditional profile but that insurance was very welcome by the test pilot. The company recognizes that the battery life gives to buy bread, but the bread and the newspaper, so the helicopter works in a version equipped with of a hybrid motor gasoline used to recharge the batteries that feed the engines.
The maneuverability of the Volocopter is very accurate. How to use several fixed pitch propeller instead of a single variable pitch propeller, the direction is controlled increasing the revolutions of different groups of propellers. The fact that the propeller is not of variable pitch also prevents perform maneuvers of autorotation to cushion the descent in the event of motor failure.
From e-Volo they downplay this detail and explain that the amount of engines provides sufficient redundancy as one so that there is no risk when it fails. Another issue is that you there is a massive failure for unlikely reasons, as for example at random, that the batteries die, so you better not add churros for breakfast on Sunday.
