Flight safety is a thing all pilots talk about. They live it, settle for it, and generally hope to pick it within their day-to-working day life while in the aviation world. For that Super Cub fanatic, the Prolonged Slotted Wing from Dakota Cub offers pilots the opportunity to boost their safety margin along with boosting the climb effectiveness on the plane.
Visualize flying your Super Cub at a substantial angle of attack While using the airspeed indicator looking through 20 mph, then rolling into 60-levels superslot of bank and initiating a climbing spiral although deciding on a power environment that is below whole throttle! Which is the typical exhibition that sells the Dakota Cub Prolonged Slotted Wing. The 2nd most discussed high-quality of this wing is the ability to have full flight Handle authority at high angles of assault. No a lot more soft controls, plopping it down, or wing fall on stall.
Mark Erickson, the founder of Dakota Cub, commenced his mission in the 1990’s. All he wanted was a Cub rib. Very little from Piper was offered at an inexpensive Price tag and since the Piper ribs have been so fragile, he decided to Create his individual. He utilized contemporary-day know-how to an previous Piper wing that was originally formulated for your YL-fourteen liaison Variation in the J5C Cub. The YL-fourteen wing was a slotted wing. As outlined by Erickson, there were only 14 of such plane developed before the stop of Globe War two. They have been specifically engineered for brief take-offs of 100-ft and climbs with high angles of attack. You can find only two of these continue to in the air today – 1 in Spain; one other in Nebraska.
The Dakota Cub Extended Slotted Wing has several variances in comparison to the initial Cub wing as well as the L-14 wing for that matter. Erickson revised the first Piper US35B airfoil utilized for the L-fourteen. He produced a personalized “T” shaped extrusion with the same dimensions that when Utilized in developing a truss-design rib, is lighter, less difficult to operate with, and more robust than the initial wing. Erickson acquired a STC for The brand new wing in 1993.
Erickson’s new rib only adds 7 lbs to the load of each authentic Piper wing. The new wing is structurally tested to in entry of two,200 lbs, nonetheless, the STC boundaries the gross pounds to one,750 lbs for the first wing or two,000 lbs for all those wings Geared up with the Wipaire Just one Ton Cub STC. This synthetic reduction will with any luck , be transformed Later on. While in the intervening yrs, Erickson has designed ribs and a number of other components that are FAA PMA-ed for all rag-wing Pipers. Erickson was granted the STC for the total-size leading edge slot in 1998. This slot assists protect the boundary layer of airflow at sluggish speeds. Along with that, Erickson engineered a squared off wing and got rid of the tip bow providing the wing a further six% floor location, amplified the flaps which results in forty four% more flap place, and pushed the ailerons outward 23-inches to the edge of the wing. He calls it the “Prolonged Wing.” The squared wing adds about 8 lbs to the initial Piper wing.
