Flight protection is something all pilots converse about. They Dwell it, accept it, and often hope to choose it inside their day-to-day lives within the aviation entire world. For the Super Cub fanatic, the Extended Slotted Wing from Dakota Cub presents pilots the opportunity to enhance their protection margin and boosting the climb overall performance with the aircraft.
Think about traveling your Tremendous Cub in a high angle of attack Together with the airspeed indicator examining 20 mph, then rolling into sixty-degrees of bank and initiating a climbing spiral whilst deciding upon a power placing that’s below full throttle! That is The everyday exhibition that sells the Dakota Cub Extended Slotted Wing. The second most talked about top quality of the wing is the chance to have entire flight Handle authority at superior angles of attack. No a lot more soft controls, plopping it down, or wing fall on stall.
Mark Erickson, the founding father of Dakota Cub, started his mission in the 1990’s. All he wished was a Cub rib. Absolutely nothing from Piper was available at a reasonable Charge and since the Piper ribs were being so fragile, he made a decision to build his personal. He used present day-working day know-how to an previous Piper wing which was initially produced for that YL-fourteen liaison Gclub Variation of your J5C Cub. The YL-14 wing was a slotted wing. In line with Erickson, there were only fourteen of those plane built ahead of the stop of Entire world War two. They had been especially engineered for short choose-offs of a hundred-ft and climbs with significant angles of assault. You will discover only two of those continue to in the air nowadays – a single in Spain; another in Nebraska.
The Dakota Cub Prolonged Slotted Wing has numerous variances when compared to the initial Cub wing as well as L-fourteen wing for that matter. Erickson revised the initial Piper US35B airfoil used for the L-fourteen. He produced a tailor made “T” formed extrusion with the similar Proportions that when Utilized in building a truss-design rib, is lighter, easier to operate with, plus more sturdy than the initial wing. Erickson attained a STC for the new wing in 1993.
Erickson’s new rib only adds seven lbs to the load of each authentic Piper wing. The new wing has actually been structurally examined to in access of two,two hundred lbs, on the other hand, the STC boundaries the gross body weight to 1,750 lbs for the original wing or 2,000 lbs for people wings equipped While using the Wipaire One Ton Cub STC. This artificial reduction will ideally be modified Down the road. During the intervening yrs, Erickson has developed ribs and all kinds of other sections which might be FAA PMA-ed for all rag-wing Pipers. Erickson was granted the STC for the total-size main edge slot in 1998. This slot will help maintain the boundary layer of airflow at gradual speeds. Along with that, Erickson engineered a squared off wing and got rid of the tip bow providing the wing a further 6% floor space, amplified the flaps which ends up in 44% a lot more flap space, and pushed the ailerons outward 23-inches to the sting of your wing. He phone calls it the “Extended Wing.” The squared wing adds about 8 lbs to the initial Piper wing.
