With the October 2011 picture of his first and only test trip of a jagged proof-of-concept 16-rotor aircraft dubbed Multicopter 1, engineer and scientist Thomas Senkel created an Internet experience. The German start-up e-volo, the maker of the experimental private aviation craft, has a revised “volocopter” design that includes two more blades, a serial cross drive, and long-term plans to convert to 100 % battery power.
The new design calling for 1.8-meter, 0.5-kilogram carbon-fiber blades that are connected to a machine. Over a shapeless one- or two-person pilot, they are arranged in two concentric circles around a gateway.
Yolanka Wulff, senior director of The Charles A. and Anne Morrow Lindbergh Foundation, accepted the concept of the multi-blade heli at first as “nutty” after receiving the volocopter idea a Lindbergh Prize for Innovation in April. Nevertheless, she claims that e-volo’s strategy excels in health, energy efficiency, and simplicity, which were the main factors in the novel look.
All three qualities are brought about by Volvo’s treatment of outdated aircraft components. Second, the tail growth, transmission, transmission, and neck rotor, which are all energy-robbing, are all gone. Although the gigantic blades that extend above a typical helicopter’s room create raise, the craft is subject to a lot of stress and wear as a result. The little tail rotor, perched horizontally over on a boom behind the cabin, consumes about 30 % of a pilot’s energy as well, which prevents the body from spinning in the opposite way as the main blade.
Many rotor blades on a volocopter would not produce the torque that a single huge rotor would, and they provide duplication for safety. As long as those rotors weren’t clustered together on one side, according to Senkel, the plane’s co-inventor and cause building engineer for e-volo, the volocopter could sail with as few as 12 functioning rotors, theoretically.
Without the classic two-prop design, the art may be lighter, making it more fuel-efficient, and reducing the actual difficulty of using a single website to generate energy to the top and rear blades. Volocopters do not require a transfer that is energy-hungry. In fact, according to Senkel,” there will be no structural connection between the gasoline engine and the blades.” More reliability for health and fewer energy-loss points.
The blades are no longer dependent on a single source of power, thanks to E-volo’s pattern. The volocopter may include a gas-fueled website, in this case an engine capable of producing 50 to 75 megawatts, which is typical of ultralight airplane, as a serial-hybrid vehicle. The engine may power the electric motors and charge the lithium batteries onboard rather than physically drive the rotors. If it fails, the batteries are supposed to have much backup power to allow the ship to land safely.
The flexibility of a volocopter will depend on changing the frequency of individual blades, as opposed to helicopters ‘ flexibility when they change the angle of the main and tail blade blades. Instead of steering pedals, a power rod, and a valve, it is more accurate in theory to command a craft using three to six redundant devices ( in case one or more fails ) interpreting instructions from a pilot using a joystick-like game console.
Wulff’s initial impression of the volocopter’s design is not uncommon. The many-winged would-be flying machines of the late 19th century are reminiscent of E-volo’s computer-animated promotional videos of a glittering white craft hidden beneath a thatch of blades. This is not lost on Senkel.
He claims,” I understand these skepticisms.” The overall design concept resembles a blender. However, we are actually creating a safe flying machine.
That would be significant progress in itself. Multicopter 1 resembled something from a particularly iffy MacGyver episode, complete with landing gear and a silver yoga ball. Senkel rode seated among all those lithium-only rotors. The Multicopter 1 hovered for just a few minutes, reaching an average of 20 kilowatts.
The experimental craft only flew once, for a limited period of time. That first craft is described by Seiner as “glued and screwed together.” He claims,” I was aware of the fact that I will be dead, maybe. I was sitting on the same platform as the spinning blades. Additionally, we demonstrated the utility of the idea. What do we gain by flying it twice? He asks in a rhetorical manner.
The revised volocopter design would operate largely the same as the original prototype, aside from putting the pilot safely below the blades. According to Senkel, the design calls for three to six redundant accelerometers and gyroscopes to measure the volocopter’s position and orientation, creating a feedback loop that gives the craft stability and makes it easier to fly.
The revised prototype of the Volocopter that is currently being built might be available in spring. The first commercially available models, which are expected to take at least an hour at speeds exceeding 100 kilometers per hour and have a minimum altitude of about 2, 000 meters, which is still far below the standard helicopter’s normal operating altitude of about 3, 000 meters, are expected to fly for at least an hour at speeds exceeding 100 kilometers per hour. This might alter our lives, but I don’t anticipate anything quite that for ten years, Senkel adds.
” This idea is fairly easy to realize,” says Carl Kühn, managing director of e-volo partner Smoto GmbH, a company that integrates electric drive systems and related components. The majority of the technology needed to build the volocopter is already available.
Kühn continues to emphasize the standard nature of the technology involved, but he has modest short-term expectations like Senkel. ” I guess that e-volo will have a prototype ] aircraft that can carry one or two people from one point to another in three years,” he says.
The biggest immediate limitations appear to be regulatory. For instance, European aviation regulators deem any electrical system exceeding 60 volts to be high voltage and more forcefully regulate these systems, according to Kühn. In consequence, the volocopter will operate below that limit. According to Senkel, the craft will need no more than 450 kilograms to fit into the ultralight category, which is also subject to fewer government aviation regulations.
Wulff, a representative for the Lindbergh Foundation, claims that the judges had” a greater than 50 % chance of succeeding” if they had not awarded them the innovation award. When asked if she would make a line-up for a flight one day, she replies,” I sure would. I find it to be very compelling.
