Slope Excellence. Though the weighted average of my public facing work gravitates to dynamic soaring, my true passion is slope soaring, followed by hand launch and open field soaring. (This is a great segway to make clear that for the DS models I've developed, the customer has taken on the structural engineering aspect themselves, and full congratulations and credit goes to them. I do not have great skills in structures associated with dynamic soaring, and structure certainly goes beyond just throwing carbon at a DS project.) The Buff Superior will be the second collaboration between CyberModelle and L2 Airframes of San Diego California, the molded JW flying wing being the first. Buff Superior will be a pitcheron aircraft, in that the wings pivot to provide both pitch and roll. The horizontal stabilizer is fixed in position with a very slight downforce set against the line of flight. There may be a few that will recognize the canopy outline. If you do you are correct, this is an exact replica of the canopy outline used on the pitcheron models produced by Ken Sturh in the mid to late 70's. Here again is another segway to say that I had contact with Ken what seems to be centuries ago, and that observing his work drove me to design with organic forms in mind from that point forward. Using the canopy outline is intended to be an open thanks for influences that floor me still today more than 30 years later. Lucky again, I have a huge pile of drawings plus shop drawing from VS Sailplanes to work with, a gift from another contact with closer ties to the source. Lucky a third time, the model will be rapid prototyped by none other than Joe Cormier, a very top shelf builder who himself still produces a very high quality replica of the fabulous Vmax. The prototype model will take two forms; one sectioned with a highly tuned Eppler 374 and another with a very highly tuned HN-871. Aside from the standard process of curve optimizing, the wings will have their max camber achieved on the aerodynamic centers chord line. Inboard from that point and outbound from that point camber is reduced, but not by the same amount. For example, the Eppler version will see 2.24% camber on the wings AC, but 1.75% at the root and 1.5% at the tip. This should work out very nicely and grant terrific control at nearly all speeds. The model will be equipped with a wing boss that will guide the pilot in tuning the precise ideal incidence angle of the fully pivoting wing. The Rapid Prototyped models produced by Joe Cormier will be shaken down to best tune the stabilizer dowforce setting, and to drive the choice as to the section that will be used on the production model. From that point the aircraft will be mass produced in the PRC. The builder in fact is already tooling up. Stay tuned. This will be a terrific model, and a great transition beyond dynamic soaring alone.
