Assymetric Flying Wing A few thoughts by Koen Van de Kerckhove To start: select slide-show in menu VIEW Click mouse to advance

Moment Tail Turn Engine Principe of assymmetric balance Airflow Rotation Tail CG Conventional airplane

Moment Tail No turn Engine Drag Weight Principe of assymmetric balance Rotation Airflow Drag E and T and D compensate turning Tail CG Weight Compensate moment M Blohm & Voss 141

Principe of assymmetric balance Which solution for tailless designs? No tail ! No force T ? No force T (Vision 1)May not create force D No forces T and D Prop needs to lay in center Problem: where to place engine and cockpit? Tailless airplane

M Weight Principe of assymmetric balance My way of thought (Vision 1) CG M Rotation Weight Compensate moment M No choice, prop in center. Moment M CG of center to left side Problem: How is it possible to place a CG of center AND the cockpit in center Tailless airplane

Principe of assymmetric balance Other idea No tail ! No force T ? No force T (Vision 2) E and D have to compensate CG and Prop of center Tailless airplane

M No turn Engine Drag Weight Principe of assymmetric balance My way of thought (Vision 2) Engine Drag CG M Rotation Weight Compensate moment M Due the rotation prop CG and cockpit on left side of center Moment and Weight compensate Engine and Drag compensate Tailless airplane

M No turn Engine Drag Weight Problem with this vision CG Rotation Compensate moment M If E and D compensate there is no more propthrust left to move the plane forwards Tailless airplane

No turn Drag Engine Principe of assymmetric balance My way of thought (Vision 3) Drag Engine CG No force T E and D have to compensate E to the right (Vision 3) E and D create moments around CG E and D compensate the moments around CG Still enginepower left to move the plane

Is my way of thought correct? Did anybody make RC models in this way? Any others comments are also welcome. Keep that brain spawning wings. Koen Van de Kerckhove member of Nurflugel-mailing group (www.nurflugel.com)
