Future of Flight? First Manned Multi-Copter Flight by e-Power

The e-volo multicopter is an innovative, vertically starting, human carrying transportation device that is uncatagorisable to its current flight counterparts.

The e-volos sixteen propellers allow it to take off and land similar to a helicopter. Its massive plus points compared to a helicopter are the simplicity of its engineered construction without complicated mechanics and its redundant engines. Should anything go wrong, e-volo can still safely land even if up to four of its sixteen motors should fail. Flight time can last between ten to thirty minutes, depending on the payload and the capacity of the lithium batteries. With an empty weight at 80 kg (including batteries), e-volo fits into the class of ultralights.

In difference to other helicopters or multi-rotors, e-volo can use a safety parachute, as there are no propellers blocking the deployment area above.

The propellers create the full lift, and are also responsible for balancing the device on all three axes only by independent speed control of the motors. E-volo from the beginning has been designed entirely as an electrically powered device. Unlike the rotor of a helicopter, the propellers dont´t have any pitch control and therefore no wear. These factors make the multicopter mechanically simple, with close to no maintenance necessary.

The automatic attitude and directional control are taken care of by multiple separate and mutually monitoring onboard computers, controlling the engines with the precise rotation speed necessary to fly this tri-axis device. A simple joystick allows the pilot to control the aircraft via a fly-by-wire system. Whether during vertical takeoff, in flight, or landing, the pilot has to pay little attention to minimum speed, stall, gas mixture control, pitch control or one of many other things that make conventional flight as challenging as it is. _e-volo

At the end of October 2011, Thomas Senkel of e-volo had completed a series of unmanned tests and was ready for the first manned flight on an airstrip in the southwest of Germany. The flight lasted one minute and 30 seconds, after which the constructor and test pilot stated:

"The flight characteristics are good natured. Without any steering input it would just hover there on the spot".

This could be the future of flight, piloting a device as simple as a car. _e-volo

Combine a precision multi-copter with a lighter-than-air lifting body, and you have the makings of a flying pickup truck all-purpose utility vehicle.

70 Kg Seaplane from Finland

PO
This one-seater carbon fibre plane lands and takes off on water, and weighs but 70 kg. It was designed by a Finnish aerospace engineer, has a topspeed of around 140 kph, and a wingspan of 5m. It will come in multiple models, with prices starting at US$ 39k. The company plans to start taking orders in 3 months.

The first version, one electric only, and two fuel based versions. The electric-only version has a 20kW engine. The two petrol-based engined run on 24 bhp and 35 bhp, respectively. The top speed on these planes is roughly 140 km/h, with a minimum speed of 70 km/h . The FlyNano has a wingspan of five meters. The plan can support a take off weight of 200 kg, as well as a take off speed of about 70km/h. In theory, the plane can travel about up to 70 kilometers in a single fueling, or charging, depending on the model that you have chosen to fly. _PO

The plane would be mainly for sport and recreation. For lake hopping, island hopping, or seastead hopping, the plane might be practical as a light mail carrier or courier craft. Future STOL (short takeoff or landing) versions of such planes might be convenient for getting out of a populated area quickly. Just be sure to have plenty of fuel caches pre-placed.

D-Dalus: A Possible Revolution in Flight from Austria

At the heart of D-DALUS is a revolutionary propulsion system containing a number of patented inventions, including a friction free bearing at the points of high G force, and a system that keeps propulsion in dynamic equilibrium, thereby allowing the guidance system to quickly restore stability in flight.

The propulsion consists of 4 sets of contra-rotating disks, each set driven at the same rpm by a conventional aero-engine. The disks are surrounded by blades whose angle of attack can be altered by off-setting the axis of the rotating disks. As each blade can be given a different angle of attack, the resulting main thrust can be in any required direction in 360° around any axis. This allows the craft to launch vertically, remain in a fixed position in the air, travel in any direction, rotate in any direction, and thrust upwards thereby ‘gluing down’ on landing. _D-Dalus Detail

Austrian research company IAT21 has presented a new type of aircraft at the Paris Air Show which has the potential to become aviation's first disruptive technology since the jet engine.

The D-Dalus (a play on Daedalus from Greek mythology) is neither fixed wing or rotor craft and uses four, mechanically-linked, contra-rotating cylindrical turbines, each running at the same 2200 rpm, for its propulsion.

The key to the D-Dalus' extreme maneuverability is the facility to alter the angle of the blades (using servos) to vector the forces, meaning that the thrust can be delivered in your choice of 360 degrees around any of the three axes. Hence D-Dalus can launch vertically, hover perfectly still and move in any direction, and that's just the start of the story. _Gizmag_via_NBF

This propulsion system may eventually scale from the microscopic to the size of large freight haulers. I suspect it will be pursued initially as a spy and surveillance platform, and as an insertion and extraction method for special ops teams. Also as remotely-operated stealthy substitutes for attack helicopters such as the Apache. Eventually, it may provide the platform for flying cars and flying boats, among other consumer and adventure toys.

The most obvious and immediate application for D-Dalus is as a little flying spy robot that can fly in doors and windows and snoop around indoors. Larger versions would be perfect for search and rescue missions, and the designers even think that in the long term, vehicles based on this technology might be what you use to commute to work. That's right — flying cars! _Dvice

I suspect that these toys will prove quite expensive to buy, operate, and maintain, but I would like to be proven wrong about that. At this point, they are at the prototype stage, and may not become reliable enough for even military use for quite some time.

Gyroplanes of the World

From Sport Copter of Oregon:

In case you didn't already know, "gyrocopter", "gyroplane", "autogiro" and "autogyro" all mean the same thing, and the most important feature shared by gliders, airplanes, helicopters and gyroplanes is that they all use wings to fly. It's just that on helicopters and autogyros the wings are mounted on pylons and spin in circles, but they are rigidly affixed to the sides of airplanes and gliders. Other than that, they all get into the sky the same way: You move a wing rapidly through the air and it produces Lift. The rotating wings of a helicopter are directly-driven by the engine, enabling it to hover; whereas the rotating wings of the gyroplane are free-spinning, meaning it can't hover – though it can come astonishingly close to it, because it needs very little forward speed to stay airborne.


The cardinal virtue of the gyroplane is its ability to do nearly everything a helicopter can do, at only a fraction of the cost, while doing it more safely than any other kind of flying machine. While even the most mundane gyroplanes are true STOL (Short Take-Off/Landing) vehicles, they can be configured to take-off and land with no ground-roll at all. Moreover, their exceptional STOL capabilities make them terrific for "bush" or water operations. Helicopters are vastly more mechanically complex than any other kind of aircraft, with a host of critically interdependent moving parts, which is why they cost several times as much to purchase and maintain as a same-sized gyroplane. Meanwhile, many gyroplanes can be purchased and operated for less than some motorcycles, and because they fly in a constant state of autorotation, even a total engine failure results in a parachute-like descent, making them the safest of all aircraft.As if all that weren't wonderful enough, a typical gyroplane can stay aloft at 5 to 10 knots airspeed, and even a small gyroplane (in the hands of a competent, experienced pilot) can be operated safely under high wind conditions that would keep gliders, ultra-lights, blimps, balloons, space launches and most private airplanes on the ground. Moreover, gyroplanes are capable of the same forward speeds as helicopters. This is so because of the rotating wings, and their "wing-loading", a term describing how many pounds of an aircrafts total weight are supported by each square foot of its wings; Gyroplanes have very high wing-loading because their rotorblades have so little total area, using rotational speed rather than size to generate lift. So gyroplanes really do offer exceptional utility. _SportCopter

SportCopter of OregonGyrocopters provide an amazing freedom of movement at a relatively low cost. They can be equipped with skis for snow and ice, or floats for water TO/Ls. If you need to make a quick getaway from a gridlocked mega-city when the fecal matter hits the rapidly rotating blades, consider the lowly gyroplane.

Auto-Gyro

The newest addition to the gyrocopter genre arrived at Aero Friedrichshafen this week in the form of a side-by-side, fully-enclosed, composite construction Cavalon gyrocopter. The gyrocopter is to the helicopter what the microlight is to traditional small aircraft. Invented in 1923 by Spaniard Juan de la Cierva, the gyrocopter uses quite a different layout to the helicopter to give it stability at low speed. It is cheap to run, takes off and lands on a ridiculously small footprint, and has a powered pusher propeller in addition to an unpowered main rotor.Certification for the EUR65,000 Cavalon is almost complete in Germany and France, and AutoGyro will assist with certification documentation for other countries. Additionally, there are still ten units up for grabs in this year's production run.

The closest competitor to the Cavalon is the Xenon gyrocopter built in Poland, though the Xenon has the one-axle cyclic control while the Cavalon has a two-stick arrangement and the Cavalon stores its fuel outside the cabin. _Gizmag

Bulletproof Super-Cat Has Its Own Amphibious Plane!

The Aeroyacht 110has been dubbed “the world’s most innovative super catamaran” by its designers and, while that’s a pretty big claim, it’s certainly an audacious concept. Capable of speeds of over 32 knots but able to cruise effortlessly at 20, boasting a superbly-appointed 32ft wide salon with 360º sea views and with its own fold-up amphibious plane as a tender, the Aeroyacht 110 looks to be the ne plus ultra of luxury sailing.

Designed from scratch by Gregor Tarjan, founder of Aeroyacht International, together with naval architect Pete Melvin, of the world-renowned Morrelli & Melvin multihull architects, the Aeroyacht 110 was designed from the outside-in. Tarjan started with the concept for a “pure sailing machine” and, once its streamlined shape was established, only then worked out how many people it could and should accommodate.Source
The amphibious tender ICON A5 adds a completely new dimension of freedom to the maritime ensemble. All that is lacking is a small submarine. Perhaps the Aeroyacht people can correct that oversight by the time the super cat hits the market.
