TED: 3D printed jumbo jet

A short TED video of less than 6 minutes in which Bastian Schaefer looking at the future of aircraft building through the technology of 3D printing.

Designer Bastian Schaefer shows off a speculative design for the future of jet planes, with a skeleton inspired by strong, flexible, natural forms and by the needs of the world's, ahem, growing population. Imagine an airplane that's full of light and space - and built up from generative parts in a 3D printer.

Bastian Schaefer and a team of designers at Airbus have been imagining the high-concept future of the jet airlplane - in a future with less fuel and more passengers.

How many years will it take for the first 3D printed cars to drive around and planes to fly around?

Update: first flying car allowed on the road

Many commuters would do a nice thing to be able to fly over the crawling traffic jam. In the United States, the time has finally come with the Terrafugia Transition. The first on the road are expected in 2012. The Dutch PAL-V One will soon also take to the air.

Flying car designers usually focus on the flying element, which usually results in an airplane or helicopter with wheels, or on the driving element, which produces a car with wings or rotor. The Dutch PAL-V is most like a wheeled helicopter, so it clearly falls under the first category.

The mobile single-person helicopter (or flying tricycle) PAL-V One will cost approximately $ 300,000 (approx. 250,000 euros), according to the manufacturer PAL-V. The means of transport has a maximum range of 560 km and a maximum speed of 180 km / h. Laughing past the morning rush hour becomes a simple matter. In short: this could well become the ultimate status symbol for the wealthy in the packed Randstad or in Moscow, which is also impassable due to the many traffic jams.

Because the plane flies lower than 1200 m, there is no interference with commercial air traffic and the owner can therefore take off without the usual aviation bureaucracy (think of submitting a flight plan, for example). The plane flies on gasoline.

 

 

The vehicle can take off very quickly by deploying its wings.

A family car is not the flagship of the American manufacturer Terrafugia: only one driver fits in the cockpit. The plane needs about five hundred meters of runway to take off. In principle, this should therefore be possible on a motorway.

The flying car weighs just over four hundred kilos when empty. In the air the moving plane can reach 185 km / h, on the road 115 km per hour. In the air, the plane uses about one liter of fuel per nine kilometers, on the road the vehicle drives 1 in 15.

Not that fuel costs will matter much to the proud owner. You own the plane for about a quarter of a million US dollars (approx. 180,000 euros). Space has been reserved for golf clubs, which also makes clear what the expected target group is for this vehicle.

Electric plane more economical than car

In a competition organized by NASA, two electric planes turned out to be more efficient than even an electric car. Is electric air traffic the solution to our energy and environmental problems?

Aircraft often more economical
Aircraft, especially helicopters, are known as fuel slurpers. Sites such as those of our colleagues from Cassandraclub regularly refer to the inefficient and energy-consuming nature of air transport. Peak oil will soon put an end to this polluting luxury, according to Cassandraclub. Yet this is not the whole story. Large long-haul passenger aircraft, such as the Airbus A300 or Boeing 737-400, when fully filled, appear to be considerably more fuel-efficient per passenger kilometer than passenger cars (around 35 km / l, compared to 20 km / l for an economical petrol car with only the driver). The most economical (but unfortunately unaffordable) is transport by train. A large helicopter, on the other hand, chases more than a liter of fuel per kilometer through it.  Source: Wikipedia.

Lift and drag
Aircraft don't have rolling resistance like passenger cars, but have to contend with another fundamental problem: lift and drag. The aircraft must be lifted enough to keep hovering, the lift, but this means higher air resistance, drag. Aircraft designers have been working for decades to come up with ways to get the lift / drag ratio as high as possible without deteriorating other aircraft characteristics, such as controllability or payload, too much. The most fuel-efficient aircraft now score around 40: 1. This means that one kilometer of descent results in 40 km distance. Naturally, the aircraft's propellers compensate for this drop. In general, lower weight also means lower fuel consumption. One percent less weight means 0.75 percent less fuel consumption.

Airplane flies twice as efficiently as a car
No wonder, then, that lightweight and strong high-tech materials, such as carbon fibers, are very popular in aviation. This has the necessary spin-off towards space travel, where weight problems are possibly even more important than in aviation.
NASA therefore organized a competition to develop the most fuel-efficient aircraft ever.
The winner, the four-person Taurus G4, flew 320 km in two hours, using 8 liters of fuel equivalent. So per passenger per liter of fuel 160 km away. In comparison, an economical passenger car with four passengers would need twice as much fuel for the same distance, and at a much lower speed. The Taurus G4 even beat electric cars by a factor of two.

Environmentally friendly flying holiday?
The disadvantage of the Taurus G4 is that the plane has two cockpits around the propeller instead of one behind it. The passengers are then seated one after the other. Also, not everyone is a gifted pilot. On the other hand, there are automatic guidance systems for this and driving is also very unsafe. If these aircraft are also able to be made as larger models and better and cheaper batteries will be introduced, flying holidays will be much more energy-efficient than now. Even an avid runner like the webmaster of Cassandraclub will probably be persuaded to book a nice electric flying holiday to the sun.

Video: flying sphere developed

Sato demonstreert zijn vliegende bol. Erg nuttig, zowel voor het redden van mensen als voor bedrijfsspionnen en roddelpers-journalisten.
New Age liefhebbers geloven in lichtgevende orbs, die op door geesten geteisterde plaatsen rondspoken. De Japanner Sato heeft nu een echte vliegende bolvormige drone ontwikkeld. DE oplossing voor nieuwsgierige journalisten en hulpverleners?

Defensie-ingenieur Fumiyuki Sato liet zijn ronde observatiedrone zien in Tokyo. De holle bol kan door nauwe steegjes vliegen, boven een bepaalde plek blijven rondzoemen, verticaal opstijgen en zelfs over de grond stuiteren. De drone is ongeveer zo groot als een strandbal en is bedoeld voor de nationale Japanse obsessie: foto’s maken.
De bol blijft in de licht door een propellor die door het bolvormige open frame wordt beschermd. De bol kan dus een stootje hebben. Sato en zijn team zijn bezig de drone te vervolmaken, maar denken dat hij in dit stadium al geschikt is bij politieacties, om verkeer te controleren en voor spionagedoeleinden.

Ook zou de bol erg handig zijn om bloedige gijzelingsacties of moordpartijen, zoals door de terrorist Anders Breivik, eerder te kunnen beëindigen en sluipschutters een goed zicht op het doelwit te kunnen geven.

Sato hoopt ook op vreedzame toepassingen, zoals search and rescue (SAR) operaties in rampgebieden. De vliegende bol kan door gebouwen en zelfs door trappenhuizen vliegen. Volgens Sato is het het eerste vliegtuigje in zijn soort. En… wij kennen wel wat journalisten bij het nu opgeheven News Of The World of andere roddelbladen die een moord zouden doen voor een uurtje met dit toestel spelen in het Britse koninklijke paleis.

Airplane of 70 kg replaces car

Woehoe!!! Mogen we u voorstellen aan de FlyNano, de nieuwste nachtmerrie van de Nederlandse luchtvaartautoriteiten.

Heb je het helemaal gehad met de ochtendspits? De Finse visionaire luchtvaartengineer Aki Suokas heeft de oplossing: de FlyNano. Omdat het vliegtuigje zo licht is, heb je er in veel landen geen vliegbrevet voor nodig. Wel een duikpak en een zwemdiploma…

De FlyNano is een watervliegtuigje dat geheel bestaat uit extreem lichte koolstofvezel, wat het lage gewicht verklaart. Er zijn twee versies: op elektriciteit en op benzine. De elektrische versie heeft een 20 kW motor. Het bereik is 40 km (elektrisch) tot 70 km (benzine). De minimum snelheid is 70 km/h, de maximumsnelheid het dubbele. Het vliegtuigje kost 25.000-27.000 euro af fabriek exclusief BTW. Ongeveer evenveel als het gemiddelde blik op de weg.

Kortom: wij weten het wel als forens. Koos Spee, van boven!
