Default Velocity Twin Introduction

Here are a few pictures of the new V-Twin introduced at S&F. Seem a few on the Veloicty mail list don't like the big ol' tail. I don't think it looks all that bad. The factory rep thinks with two 320's (160 hp) that it may have a better fuel burn than one 540. It is all to be seen since they just had the first flight on 3/13/12.

Not a lot of pictures yet.

IMO it's beautiful!
Yea two SMALL gratuitous swept back winglets would have been much schweeeter visually and in keeping with the traditional canard aircraft appearance. YMMV. But I would've liked that. Maybe with feedback in this direction they will add them. Which brings me to me next point which I ragged about when the velo-designer (I forget his good name) was on the old Canard Zone asking for feedback on this design, a few years ago...the "windshield look";
They really improved the old front car-like windsheild from before, and rounded the transition of the front where it meets the new front canopy. Now it looks like an aircraft, instead of car-like.
VERY NICE!
Good on ya Velocity. Making the Brand PROUD!

Now gettin' some nice performance stats would be GREAT!

It seems that it's been flying for two weeks.

So how did it make it to Lakeland?
Is that part of the test area?
They flew off the 40 in two weeks?

Lakeland is 81nm, and 75 is pretty typical (my test box was 75nm), so I'm guessing the FSDO worked with them knowing they wanted to get to SnF.

Danny Maher was the original designer.

Thanks for the pics! So cool.

I imagine they went with the vertical stab in the center because it was far simpler to rig something that big once instead of twice. It's gotta be a good size to keep Vmc low. I bet they couldn't use the wing tips for yaw control because the arm from the cg wasn't long enough in that position. It's all about low Vmc in twins...

That thing is so sexy...

Yes, we got an extension of our flight box to go as far as plant city so we could get the plane to the show. It definetly does not have 40 hours on it. John has done all the flight testing on the plane so far although myself and Duane have flown it. We have a couple of engineers involved with the project and the tail size is a result of what we need with aft CG one engine operation. We purposely left winglets off the plane for now until we evaluate the controllabilty of the plane in all configurations. During testing you may see winglets, fences, vortilons, etc. So far we are very pleased with the results. I know there are those that can't hardly stand it that there are no winglets on the plane but this was not just about slapping two engine on an XL, we wanted to handle engine out operation with the best option available. Since this prototype started life as an XL, we had to make some compromises that we won't make on the production versions. You can see some video by using this link http://vimeo.com/39171839 or going to vimeo and serching for secret V-twin. I hope this answers a few of the questions you might have for now. Scott S.

Lightbulb Re: Velocity Twin Introduction

Also, remember this is a prototype. The word from the factory is that they plan on some experiments with the addition of wingtips to determine if they have value. Yeah, the big tail is somewhat controversial as folks seem to like the wingtips. The big ol tail is also, IIRC, for separation of the prop wash. I know little about twins...hell, I have had enough issue with my single

I hope to see it Tuesday...yes, I will have my phone/camera...heck, if I think about it, I may even take a "real" camera...

In comparison to the winglet arrangement, I doubt that the big single tail adds anything to the performance of the Velocity. I think it has been very apparent that winglets add to performance, not diminish it. Most aircraft manufacturers are adding them, not removing them.

I believe that Velocity is trying to distance itself from all other canards This change adds about as much to the performance of a Velocity as the tail fins of a 1961 Cadillac.

Meh, meh, meh.
Dissing the naked spam-can styled center dorsal are we?

Well then....lets add a lifting surface to it, and get some 'Italia design' going on..
Please can we see someone build one of these seczy 3LS airplanes...but with 5 to six seats/places?

Just wondering why this twin canard didn't need a center mounted rudder?

"Just wondering why this twin canard didn't need a center mounted rudder?"

Cuz Burt built the design and probably fought tooth and nail to keep it within the design parameters of his 'stable'. Not that it interacted, but the canard had an in flight variable sweep as well.

I was always interested about the length of the nose of this bird of his and the relationship to yaw factor vs. the winglets and rudders in a standard Rutan aircraft and his 'short nose' requirement.

But a 3LS even without the winglets is so snarky, easier on CG etc possibly vs. the chosen Velocity design. (see pic)

Well, there is the rear stabilizer.

Is that a stabilizer or a prop-strike preventer?

Also, some big aileron fences!
