Boeing has summed up the results of the second part of the GoFly competition for the creation of a personal flying vehicle. A prerequisite is the presence of a vertical take-off and landing mode. Finalists will receive $ 50, 000 each to build a working full-size prototype, which will then compete in the skies. The main prize is $ 1.5 million.
As the name suggests, Flykart2 is a kart that was taught to fly, albeit on the second try. The pilot sits in a sports chair, which is surrounded by ten propeller motors mounted in a single housing. Numerous blades are reliably covered with protective strips, and this is a big plus in comparison with other models. The downside is that Flykart2 is heavy, bulky and consumes a lot of energy in any flight mode.
The Aeroxo team has relied on rotary engine technology, so in a broad sense they are building a single-seat tiltrotor. It has 16 motors, combined into sections of four, each with a swivel mechanism. During takeoff, they are located horizontally, but as the speed increases, the apparatus begins to lean on the air with two pairs of short wings, which allows the racks to be deployed vertically and continue to move like an airplane.
The pilot is positioned here as on a classic sports bike, sitting with an inclination forward. The presence of a large windscreen and fairings gives hope that the unit is capable of flying and maneuvering at high speeds. And its futuristic look is a clear tribute to marketing: unlike competitors, you want to ride this prototype almost immediately.
It also uses the principle of transition from a vertical to a horizontal position after takeoff, but at the same time the vehicle rotates entirely. Because of this, the pilot himself becomes the "bottleneck" of the project. During takeoff and landing, he does not see the space below him, which creates serious risks in management. And when flying horizontally, he will have to balance on a very uncomfortable support, while the weight of the pilot is comparable to the weight of the machine itself, which also raises questions.
However, with a dummy on board, the Silverwing S1 flies quite well, and there is a chance that the engineers will be able to solve other problems. Moreover, this car is distinguished from other competitors by the most modest dimensions, which is important for the future commercial version.
