Terrafugia's Transition flying car - From 2012

Fresh from its maiden voyage at the 2012 New York motor show, we find out more about Terrafugia's flying car


What you’re looking at is not a piece of existential origami but just possibly the answer to a question almost 100 years in the asking. Flying cars were theorised as long ago as 1918 and were hopping, skipping, jumping and quite often crashing long before the start of World War Two. 
But while many have been designed and quite a few built, the wait for a commercially successful ‘caroplane’ has continued. But now, if five Massachussetts Institute of Technology graduates have their way, that may all be about to change.
It’s called the Terrafugia Transition and its creator and CEO, Carl Dietrich, plans to make them at a rate of “a few hundred a year”. Which is easy enough to say, but his words are backed by over 100 orders for a £175,000 machine that, as I write the day after the first production prototype was unveiled at the New York motor show, has completed a grand total of one flight.
At the controls that day was Phil Meteer, a retired USAF pilot with over 3000 hours at the sticks of craft such as the F-16 fighter and A-10 Tankbuster. Despite what must seem like stepping down from Formula 1 to a kart, he is evangelical on his subject. “Any pilot can fly it, any driver can drive it,” he says. “You can land, fold up the wings in less than a minute and drive it out onto the road, all without getting out of the car. Or plane.”
The project has taken seven years to create a functioning prototype, although a proof of concept craft was created in 2009, and Meteer managed to fly it 28 times without any incident. The new ‘roadable airplane’, as the chaps at Terrafugia like to describe it, will now embark on an intensive programme of between 75 and 100 test and certification flights and, if all of this goes to plan, customer Transitions will start to be built next year.
What they will be buying is as remarkable as it looks. Meteer: “The reason flying cars, or road-going airplanes, have failed in the past is that by the time you’ve packaged all you need for both environments, the result is too big, heavy and impractical to work. But by using materials such as carbonfibre and titanium we have got the dry weight down to under 1000lb (446kg).”
The machine is essentially a carbonfibre structure clothed in carbon and glassfibre panels. Power comes from a 1.3-litre Rotax flat four motor developing 100bhp – enough, apparently, to push the Transition through the air at a cruising speed of around 100mph, providing a range of almost 500 miles. Drive to the prop is achieved direct from the engine through a simple reduction gear to lower prop speed from the engine’s 5800rpm to a more manageable 2300rpm.
Once you land, you simply pull the gearlever from ‘fly’ to ‘drive’, decoupling the prop and engaging a CVT transmission to provide power to the rear wheels via simple belt drives.
Once out on the road, the Transition is no firecracker – but given that its tyres are sourced from motorcycles, that’s perhaps no bad thing. Still, Meteer says it will cruise down the interstate at the same 65mph as everything else and that he’s seen over 90mph from it.
The cockpit is a remarkable achievement, insofar as it manages to appear to be that of a car and an aircraft at the same time. When the wheels are on the ground you use a steering wheel and conventional instruments. Indeed, the biggest hint in here that this is not a normal car is what appears to be four pedals.
The two in the middle are an accelerator and brake as you’d expect, but the outer pedals are rudder controls. So when you want to take to the sky, you can scroll through a screen menu until an airspeed indicator and altimeter appear in front of you, pull up the joystick which has hitherto lain folded and unseen under your seat, engage the prop and take off. In theory.
In practice, it’s a little more tricky than that, and not only because are you not allowed to take to the skies without a pre-flight check, which involves climbing out and having a good look around.
“The dream of driving your car until you reach a traffic jam and then just flying over the top of it remains just that: a dream,” says Dietrich. “This is not what we’re trying to achieve here, not least because the only part of the country which allows you to take off and land on roads is in the more rural parts of Alaska.”
Much like any other aircraft, then, the Transition needs a runway on which both to take off and land. “But,” says Meteer, “there are over 5200 landing strips in the US, most of them totally under-utilised, and on average the nearest one to you will be less than half an hour away.”
In the wide open spaces of the United States, this seems a trifling inconvenience. “Over a reasonable distance, there’s not a car in the world that could keep up with our speed from point to point,” postulates Dietrich, and he’s probably right.
Besides, the Transition is more properly thought of as an aircraft with some road ability rather than the other way around. And that, as anyone with a PPL will tell you, solves the one on-going problem with using light aircraft recreationally – namely how you get to where you need to go once you’ve reached the nearest landing strip.
But perhaps the most encouraging characteristic of the whole Terrafugia team is their sense of proportion. They know there is ground to cover between now and delivery time and that one false move could kill the entire project stone dead. Bringing such a craft to market in a country so litigious and prone to mood swings that even the Toyota Motor Corporation can fall foul of public opinion is no easy thing.
Then again, the rewards could be immense. In the US there is a lower standard of licence for small aircraft flown solely for personal use, and this means you could be flying one with only 20 hours under your belt. “If you’re going for it, you could be licensed in a fortnight,” concedes Meteer.
No such licence exists outside the US and the Transition is planned currently only for sale there. “Let’s see where we are once sales start,” says the impressively sensible-sounding Dietrich, “then if all goes well over here we can think further afield.”
To Europe and the UK? “Of course, in time that could be possible. But where we think the vehicle could be of even greater use is in emerging economies with vast amounts of undeveloped land. With this vehicle you don’t have to spend billions building thousands of miles of highway, just a landing strip every few hundred miles."
Whether the Terrafugia Transition comes to something or nothing will probably be determined in the next year. My sense is that it will arouse far more interest in pilots wanting an easy way home from the airstrip than drivers seeking to negotiate their way around jams. As for what it’s like to fly, of its one and only test flight so far, Meteer said it felt “stable and easy to control”.
Then again, after a Tankbuster, almost anything would. All I can say is that if fortune really does favour the brave, these guys will deserve all the success they will get.

Take To The Skies In The Autonomous Hybrid Terrafugia Flying Car


terrafugia-3

The TF-X and Transition are a pair of hybrid flying cars designed by Terrafugia to be safer, faster and easier than anything currently on the road, and you don’t need a pilot’s license to drive one.
Despite the unfortunate happenings with Malaysian Airlines Flight 370, flying is still the safest way to travel, with the chances of dying in a plane crash somewhere around the 11,000,000:1 ratio. In fact, you’re about 5 and ½ times more likely to die falling out of bed than you are in a plane crash. Terrafugia is attempting to combine the best parts of the automotive and aviation industries in their groundbreaking flying cars.
The previously developed “Transition” is a gas powered flying car with a single engine powering both the propeller for flight and the rear wheels for road travel. The retractable wings operate similar to any plane. with about 1700ft of “runway” required for take-off. A 410 mile range ensures that you’ll have plenty of time to get in some sightseeing from the clouds, cruising at around 100 mph. Respectable 35 mpg efficiency on the ground comes at a bit of surprise, considering how cumbersome looking the vehicle is.
The Transition is equipped with driver and passenger airbags, as well as a full vehicle parachute should you be the unlucky 1 in 11 million. A down payment of $10,000 will reserve you one of these multi-purpose vehicles.
While the Transistion has been around for a couple of years, and took its maiden flight out of upstate New York two years ago, the latest brainstorming sessions have resulted in the even more advanced TF-X. The TF-X features many of the same designs but some interesting upgrades, including most importantly, a hybrid drivetrain.
Eliminating the single rear propeller design and replacing it with moveable, side mounted propellers give the TF-X the ability to take off vertically without the use of a runway, similar to a helicopter. When taking off, the wings awake from their slumber and rotate to utilize a megawatt of power to get off the ground. The power is provided by two 600hp electric motor pods, with each pod consisting of 16 individual motors. Takeoff and landing will be done automatically by the operator setting a primary target and backup landing zones in the result of an emergency.
Once in the air, the propellers fold to face forward and team up with a 300hp gas powered engine in order to reach the cruising speed of around 200 mph. Once up to speed the engine takes over completely, allowing the TF-X to recharge its batteries and close the propellers. An increased range of up to 500 miles will give you plenty of places to travel to on your day off, sans any traffic delays. A number of safety features will be incorporated, including an auto-pilot system that can land the plane in the event of unresponsive operator and automated avoidance of obstacles or weather.
The TF-X concept is still in its infancy, with many specs and pricing still to be determined. Terrafugia claims that if they’re able to achieve proper production investments, they may be able to offer the TF-X for a price comparable to the “very high-end luxury cars of today.” Whether this means something like the $80,000 Tesla Model S or closer to the $500,000 Rolls Royce Phantom is unknown, though I’m leaning towards the latter. The development team estimates an 8-12 year wait for a finished product, but with the Transition serving as a firm platform to build on, we can hope that this will be on the shorter end of that.
For those wanting to get in on the fun before anyone else, Terrafugia recommends picking up the $279,000 Transition, as loyal customers will be given preferential treatment once the faster TF-X comes out, and there definitely seems to be plenty of interest. It just goes to show that for those with enough disposable income, the sky is truly the limit.

A Remote Control Car/Helicopter Brings Flying Cars To Life

Diagram Of B, The Flying Car

Despite the fact that flying cars haven’t taken off yet (no pun intended), people have been coming up with better ways to resolve their main problems. The “B” might helicopter car be the best design yet.
Like the Terrafugia flying hybrid, this small-scale flying car called the “B” partly addresses the issue of wing, blade size and drag. When riding, the B’s blades actually don’t protrude far out like those of the rest of the flying cars. Instead they lock into place while driving, keeping a very narrow profile.
The inventor,Witold Mielniczek, certainly thought out of the box. The vehicle has no wings, which is a major plus for full-scale cars. The wheels have no hubs, spokes, or rims either. On top of that, the blades are inside of the wheels, called driving rings, and rotate to allow the B to lift off and land vertically, eliminating the need for runways.
In other words, this little remote controlled car/plane eliminates all the drawbacks of flying cars, except probably the price. Could flying cars finally have a real future that doesn’t involve folding out huge wings or dragging a trailer behind you? It’s a brilliant design.
You can actually obtain your very own B by pledging at least £320/$500 on Kickstarter. Keep in mind that if you pledge £320, you will receive an assembly kit so you assemble the B. If you pledge upwards of £370/$575, you will receive it fully assembled and ready to use.
This project has obtained about £64,000/$99,000 (73%) of its £86,500/$134,000 goal so far. Who knows, maybe one day they’ll even make a full-scale, road-worthy model?
