Have you done any 3-D CFD modeling?

Yes. A large number of tests have now been run using Large Eddy Simulation for the v.32 aircraft in both the powered and non-powered condition. The results of all tests are very exciting, and have confirmed our success in areas that are more difficult to validate using conventional methodologies. All expected performance capabilities appear to be well in hand, and basic qualities have long been well understood through unmanned developmental flight testing.

Synergy appears to show very little drag. What little there is occurs in areas we’ve designed to benefit from the use of power. Its beyond-the-textbook design principles have now been qualitatively AND quantitatively validated, and that approach was perhaps the most significant of our technical risks. (When we completed the design to the level required to start building it, the cost of this level of analysis was much greater than the cost to complete the first full size aircraft.) We have now reduced these capabilities and principles to a “next generation” algorithm for greatly enhanced conceptual and preliminary aircraft design.

We’ve also created such a powerful in-house resource… world class, in fact… that it IS possible to test all of the things aircraft designers dream about. We’re doing it, and can do it for anyone else, too. Details here.

Computational Fluid Dynamics software attempts to solve simplified forms of the equations of fluid dynamics, usually the Euler, Navier-Stokes and Barnette equations. Most CFD software has been refined to the point where a reasonable degree of accuracy can be obtained for well-known geometries and flow conditions. However we are excited to now be using an entirely new approach: no assumptions, just physics.
