BiPod Flying Car Makes (Short) Test Flights
Zothecula writes "The team at Scaled Composites pulled out all the stops to realize the final design of the company's founder and former CTO, Burt Rutan, ahead of his retirement in April earlier this year. In just four months, the Scaled Composites team went from beginning the preliminary design to the first flight of the 'BiPod,' a hybrid gasoline-electric flying car that grew out of a program to develop a rapid, low-cost electric test bed using as many off-the-shelf components as possible."
Needs a runway to take off...
"That's nice, now where's my jetpack?" comments coming.
apple lawsuit over name in 3...2...?
* Your invention requires pilots to attach the wings themselves every time they want to fly, which must require the help of a friend or two,
* Your plane shuts the pilot in a separate compartment from the only passenger seat,
* They have to trade seats when the pilot wants to switch from flying to driving (or vice versa),
* The passenger has no ability to take the controls in an emergency,
* It looks odd in the air and downright silly on the road,
* And you picked a gimmicky pop-culture-based name that will piss off a major corporation!
You must be an engineer! Welcome to Slashdot!
How can I believe you when you tell me what I don't want to hear?
From the article:
The Model 367 BiPod is a two-seat, hybrid-electric roadable aircraft.
It's not a goddamn flying fucking car, Soulskill.
You could leave, and then us idiots wouldn't have to continue defending morons such as yourself.
Our problem, is that we attempt to allow people to have their own opinion, even when thats clearly a bad idea. We could easily solve our problem by terminating anyone who makes idiotic statements. Unfortunately for you, that means you'd be shot fairly early on.
Be careful what you wish for, you just might get it.

Company Motto: "FEEL the stability of a BiPod!"
How could not one single person involved in the entire project know that a "bipod" already exists. As almost all of you know, it's like a tripod but only 2 legged and you attach it to a gun, typically a sniper rifle, to stabilize it and raise it up to eye level without the use of your hand to brace the barrel. You can't just go using the word for something else, especially when there are SO MANY BETTER NAMES!
Why does everyone jump on that thing to diss it? It's not a commercial project, it's a technology test bed. It can't be overpriced, because it won't be sold. It won't go on the roads. It's a cool project from a guy who had the means to kick it off before retiring. What the hell is wrong with you all, thought this was a geek site. Building a convertible road/flying machine in whatever form is as geeky a project as you can get...
The Human CentBiPod!!
I actually read one of the links (I know, I know...) and saw some (to my non-professional engineer eyes) great or at least interesting ideas.
Like having the "left seat" have flying controls and the "right seat" have the driving controls. Sure, as other posters pointed out, you can't take over in an emergency but I would imagine (since I don't fly a plane) it must make the controls a lot easier to design and use. I wonder why they didn't put the driving controls on the left side since I presume they would use it in the USA not say Britain? Of course you don't need separate enclosed cabins to use this idea.
I'm impressed that hybrid technology is advanced enough that you could carry the additional equipment without a crippling weight penalty. That of course allowed them to do all sorts of interesting things like decoupling the gas engines from the electric motors allowing them to be placed wherever it is best and splitting the gas engines up for redundancy. Having presumably small lightweight electric motors in the wheels takes care of a lot of power train issues I guess. Also having lithium battery assisted takeoff is good for keeping the engines smaller because they don't have to provide brief spikes in power. I wonder if the plane can generate power as it descends (like an aerial version of regenerative breaking)? Can it charge the batteries on a windy day on the ground?
From what I saw in my cursory skimming of the article, the wings are detached before the "car" goes on the road. I guess they didn't really try to optimize the design because this is just a test vehicle (and they designed and built it in a very short amount of time! 4 months!) but I imagine that as long as you're going to leave part of the gear at the airport, why not leave the rear airfoils and electric propeller? That's another benefit from the hybrid design, no mechanical coupling to the propeller, just a power cable.
Anyway even if the overall project doesn't really "take off" (bada bish!) some of these ideas seem very interesting! I wonder if high temperature super conductors could really make this idea "go"!
Theres a dude in the UK that has been trying to get a flying car to market.
Its about £300,000 to buy and will probably kill you stone dead within 20 seconds!
Looks cool but also looks very dangerous.

especially at 70mph. It its typical light aircraft construction it'll come off worse in a collision with a rickshaw, never mind a 2 ton 4x4.
I think the big problem is that in the USA, you will need to build flying Humvees to get this idea accepted. Anything smaller will be seen as an insult to American integrity, and not safe on the roads (because everybody else believes you need a 4x4 offroad capable 8 litre vehicle to buy a pint of milk from the local shops).
Apart from the fact that the two concepts (car, plane) just don't work together that well really. A bit of a laugh for folk with more money than sense to try to develop, but until we get some sort of Bladerunner anti-grav lifting and propulsion devices, just not practicable. Next up, the submarine that turns into a plane!
I wish journalists would learn the difference between a flying car and a street-legal airplane.

This sounds like a similar concept to the Terrafugia Transition, which is also advertised as a "roadable aircraft." The Transition has made a few appearances on Slashdot in the past. Apparently the Transition uses a CVT to transmit internal combustion engine power to the wheels, so it's not a hybrid like Rutan's one in TFA.

Glad I could help.
A flying car! We put wheels under a plane! Oh wait...

This is actually pretty big since this is a big endorsement for both distributed propulsion and hybrid electric propulsion in aircraft (they mention this was started as a STOL test mule before they decided to do the roadbable aircraft thing), and it doesn't use a superconducting generator/motor/cables. Would have been more interesting to see the entire wing lined with electric ducted fans though, which is the usual endgame for distributed propulsion mounted on wings (and a propulsor right in the tail to fill in the drag hole created by the fuselage).
Power densities for electric motors have gone up a lot in the last 5 years due to DARPA UAV research, so this is probably just the beginning. Launchpoint is claiming over 8KW/Kg energy density, for a fist sized Halbach array axial flux permanent magnet motor.
