Weird FanWing Aeroplane Looks Like Flying Harvester
Posted by Jesus Diaz at 3:40 AM on July 25, 2008
The FanWing has to be weirdest aircraft ever devised: it doesn't use rotors or jets for propulsion, but a patented "distributed-propulsion vortex-lift" technology which is similar to the blade cylinders used in harvesting machines. In fact, that's exactly what it looks like, a flying harvester. This prototype was presented at the recent Farnborough International Air Show, and seeing it flying in the video is weird, to say the least.
Despite the weirdness, it works. Not only that: this design allows for very steady flights and attack angles which are not possible in other aircraft without losing stability. The fan lets the aircraft to almost float in the air, with the capability of moving very slowly, resisting turbulence and winds with ease. The company claims that it also has a very low carbon footprint for "projected manned applications." As the gallery shows, they are not stopping in UAVs: they want to do ultralight aircraft, planes for short-range delivery, fire fighters, crop dusting, short-haul passenger service and even a Vertical-Take-Off version.

@aeroworks: induced drag is a function of the airfoil, forward speed, vortices and so on. Therefore simply being a fanwing doesnt mean induced drag is greater, indeed, it may be lesser. Regular drag, however, is certainly greater. Also free-spin of the rotor does not reduce drag.

2kg capacity? Stuff the nose of that thing with some light, highly explosive material or some good ol' napalm,and you have a nice little manually guided bomb. It might just be my un-informed ignorance talking, but that thing looks pretty cheap to make, so no big deal if a bunch go kamikaze right? =D

Gizomodo covered a very similar technology already called the Cyclogyro.

Click the [Flight Global] link below the gallery for a working video. I think Gizmodo messed up the embedding linkage.

If the engine failed on this the induced drag would be much greater then a normal aircraft wing. unless maybe there's a way to disconnect the fan from the motor and allow it to free spin. which would help reduce some drag...

Also, unlike helicopters which can auto-rotate and aircraft which can glide, I'm unsure what happens to a fan-wing in case of engine failure.

Worked with a fan-wing project in university that failed miserably. Nevertheless, the concept is sound. The plane itself has a virtually unlimited angle-of-attack. The rotors (yes, it does use rotors) don't however and work on the same principle as an ordinary wing or rotor.
The closest equivalent is the VS propeller system oft used in tugboats. Wiki here:

How long until someone has modded this to fly upside down and mow the lawn? And, is this rig pre-pimped because they spin?

You always expect new aircraft to be faster/sleeker/more futuristic looking... this defies all of those. I wanna meet the guy who said "I'm going to invent an aircraft that can fly slower than any other!"
Genius.

I think this one gets 25 points for being the most fugly aircraft to be "invented" in the last decade or two. All the same I wanna know how it works. Or....err.....does the earth just repel it's ugliness?

As a fan of model airplanes I remember seeing this concept on a model about 7 ~ 8 years ago.
It operates on the concept of cross-flow fans (widely use in HVAC systems because of the high static pressure they can create).
The model was extremely low speed flying.
I'm glass to see the idea taking off (no pun intended)...

Hey, this is a perfect fit for Gizmodo!
"Why is that, ps61318?" you might ask.
Because the lift created by this device might be called...
Fanbuoyancy!

Either way, this plane reminds me a lot of this '70s Braun desk fan.

@LiquidGravity: Wouldn't work with a direct connection to your tires, (weight issues notwithstanding) the direction of rotation with respect to motion would create the opposite of lift. You can see what I mean with a business card. Hold a business card horizontally with your fingertips on the long side. flick the card forward and with a backspin and it will float down to the ground. Do it with a top spin and it will go forward a little bit then reverse direction and come back to you. In effect, reverting to the backspinning blade with forward motion.

Something is screwy with the video.
It does look interesting. I wonder if I could add these to the side of my car tires. Flying cars of the future anyone?

I believe this concept is being confused with a cyclogyro. Although I can't be certain, based on the video, it appears to work on a completely different concept. In a cyclogyro, as in some wind turbines, the blades themselves are airfoils, and their spinning creates lift all by themselves. The fan wing, on the other hand, seems to be just a long cross-flow fan that blows accelerated flow over the upper surface of the wing. With any airfoil, faster airflow causes greater lift. The fact that this accelerated flow is only on the upper surface of the wing would further increase this lift. However, don't confuse it with the cyclogyros; it's just like having a bunch of tiny fans blow air along the top of the wing.

I think the only draw back of this design is the loss of power.
It will glide like a rock. (since it does not have a normal airfoil, I bet it will just drop)
For a UAV it will be OK. For people... better have a backup power system to at least do a safe landing.

Using it on a UAV is fine. For manned vehecle, it is just too easy to be jammed by a bird.

Why stopped at just one blender fan? Can they make a flying saucer with its upper side entirely covered with rows and rows of fans? Or simply add these to the roof of a blimp to increase lift.
