raiki Posted January 17, 2009 Share Posted January 17, 2009 Was fooling around today and came up with another contraption. Don't get into the "this cant work because...." !!! I am only fooling around but I like the look. It's a twin Cozy with LongEZ type strakes and swept canard (of an increased size to support the front motor). The canard is effectively a 50% scale wing. It has two Jabiru 5100 engines. Quote Adrian Smart Cozy IV #1453 Link to comment Share on other sites More sharing options...
Kent Ashton Posted January 17, 2009 Share Posted January 17, 2009 It would work but it'd be like flying a Cozy IV with 350 lbs of ballast in the nose. Takeoff roll: 15,000'. Rotation speed 150 knots. :-) -Kent Quote -KentCozy IV N13AM-750 hrs, Long-EZ-85 hrs and sold Link to comment Share on other sites More sharing options...

Rotation speed 150 knots. :-) -Kent Ummm no, because the canard area is significantly bigger than a standard Cozy. That's one of the things I did think about. Standard Cozy has 15sq.ft of canard area, this baby has 30sq.ft. Prolly not enough, defiant has 50sq.ft but 30sq.ft looks cool. Like I said, no real maths went into it and I certainly didn't accommodate the effect of sweep or the increased reynolds numbers due to increase chord. Add to that the Jabiru has an installed weight (incl. starter, alternator, exhaust, ignition) of about 270lbs. That said I have also used the lighter engine in the rear, so that exacerbates the problem. Could hang the rear engine further out the back but the fuse is long enough as it is.

Rotation speed 150 knots. :-) -Kent why would you think it would be a long takeoff? the defiant has a engine up front and they are known for there shorter takeoff roll and slower rotation speed. that is the one thing a defiant does do good. not a fast plane but a good lift and hauling aircraft. very cool to fly and you can setup your tent in the back seat.

Strider Posted April 29, 2009 Share Posted April 29, 2009 X-Plane will show you how that plane will fly, Raiki. Using PlaneMaker to enter your design into X-Plane is easier than using AutoCAD in the first place. Download my canard designs for X-Plane (VEZ, LEZ, Defiant, Cozy) for tips and methods of refinement. Search the www.x-plane.org Download Manager for my designs under the user name "vezePilot" there.
