Project Alliance
(Back to IFO Designer Page)
The Alliance R/C model is a 22' wingspan 20% scale R/C model of a proposed high altitude research aircraft for NASA. This program involved a design competition among four companies. Scaled Composites was the only of the four companies to bring a flying 20% scale flying R/C model to the competition and as a result won. |
The Alliance R/C model features “outboard” horizontal tails. These horizontal tails are situated in a favorable upwash position in the wingtip vortices which increases their effectiveness without making the tails larger. Adding more weight at the tip also decreases the wing root bending moment, which reduces the wing spar weight. Dan Kreigh built this model and was the sole pilot. |
