C-Wing: Application to Large Aircraft

The first application of this concept to an aircraft design study was in connection with recent interest in very large civil transports. Many difficulties remain to be resolved for a successful large conventional design. Airport and manufacturing constraints limit the span of a new large aircraft. The location of the outboard engine is a problem, and the height of the vertical tail becomes excessive. The C-Wing design was proposed as one way of addressing these issues and perhaps improving the performance of such large aircraft. Additional sections of this paper describe the evolution of the C-wing concept and include the following:

C-Wing Summary

The advantages of the C-wing configuration for a large capacity subsonic transport are listed below. They include those directly associated with the nonplanar wing geometry and those that arise indirectly from the overall configuration shown on previous pages.
