Pusher twin boom and pod mash up from Calidus gyro???

[TahoeTim]

Too much coffee and bacon this morning...

Take a Calidus gyro, remove the rotor and tail boom and bolt on a twin boom high wing assembly. That would be one very beautiful LSA

Who wants to photoshop one together for me?

Here you go Tim. My skills in 3d are fairly limited, but this was general layout.

Sadler Vampire.

Just found out the 2pl. is sxs with a lower wing, but the 1pl. is close.

 

[TahoeTim]

thanks

sadler is low wing

Something like this perhaps?



Someone just posted something about a Wizard, and when I looked it up it reminded me of your idea here.

Crikey, I need to post more often... now where did I put that patent... :gig:

 

[gdes]

The Sadler Vampire single place is a shoulder wing, looks very cool and is close to the 1st rendering.

But, I think you had something like this in mind:

Rendered using Stone-age Photoshop TRF, (Tracing, Ruler and Freehand)

Neat little plane. Are those cooling air intakes at the wing root?

Yes. Easier to see here: http://cdn.avweb.com/media/newspics/airventure2009/photo-galleries/03/large/02.jpg

gdes, you nailed it. MikeD, nice design and close to the look I was dreaming of so where do I buy plans?

 

[DaveD]

Do you mean me? Or is MikeD someone else :ermm:

If it is me, there's no plan to release plans!

 

[TahoeTim]

oops, DaveD

How much extra web area is there on a twin boom comparing to a conventional tail?

I've always liked that one and the Cessna XMC as well

 

[BJC]

The XMC was a derivation of the AG-14.

A single tail boom under the pusher prop would probably result in a lighter, simpler, and more easily- built airframe. The engine and prop need to be mounted higher, but this means the top of the prop disk is above the wing and incoming air isn't obstructed. The negative is that there will be some pitch change with power changes.

"AG", IIRC, stands for Anderson-Greenwood

That looks awesome. Any detailed work going on?

Not necessarily. My tail booms actually come out considerably lighter as a single tail boom would have been.

Buckling is the issue. If we look at the typical C172, ignoring buckling, skin thickness with carbon would have been on the order of 100 micron, or 2 human hairs stacked on top of each other. Throw in minimum skin thickness and sleeker tails, even as small as the 5-10" dia end up considerably lighter, especially in composites.

Structurally they're no doubt a lot harder to analyze, not entirely convinced they're any more complex (parts count in for example controls) compared to a conventional design.
