Dakota Cub’s Prolonged Slotted Wing

Flight security is one thing all pilots converse about. They live it, acknowledge it, and usually hope to choose it of their day-to-working day life during the aviation globe. To the Super Cub fanatic, the Prolonged Slotted Wing from Dakota Cub delivers pilots the chance to boost their security margin as well as boosting the climb overall performance of your aircraft.

Visualize traveling your Tremendous Cub in a higher angle of attack While using the airspeed indicator reading through 20 mph, then rolling into 60-degrees of bank and initiating a climbing spiral while picking out a power setting which is fewer than whole throttle! That may be the typical exhibition that sells the Dakota Cub Extended Slotted Wing. The second most talked about high-quality of the wing is the chance to have total flight Handle authority at higher angles of assault. No more smooth controls, plopping it down, or wing fall on stall.

Mark Erickson, the founder of Dakota Cub,  ไพ่แคง began his mission during the 1990’s. All he wished was a Cub rib. Very little from Piper was available at an inexpensive Value and Because the Piper ribs were so fragile, he decided to Make his possess. He applied contemporary-day know-how to an aged Piper wing which was originally designed for that YL-14 liaison version on the J5C Cub. The YL-fourteen wing was a slotted wing. In line with Erickson, there were only fourteen of these aircraft constructed ahead of the stop of Entire world War 2. They were specifically engineered for brief just take-offs of a hundred-ft and climbs with superior angles of assault. You can find only two of such however in the air today – one particular in Spain; another in Nebraska.

The Dakota Cub Prolonged Slotted Wing has quite a few variances compared to the initial Cub wing as well as the L-fourteen wing for instance. Erickson revised the first Piper US35B airfoil useful for the L-fourteen. He designed a custom made “T” shaped extrusion with the very same dimensions that when used in building a truss-fashion rib, is lighter, simpler to work with, and much more sturdy than the original wing. Erickson acquired a STC for The brand new wing in 1993.

Erickson’s new rib only adds 7 lbs to the burden of each first Piper wing. The brand new wing has actually been structurally analyzed to in entry of 2,200 lbs, even so, the STC boundaries the gross body weight to one,750 lbs for the first wing or 2,000 lbs for people wings Geared up Together with the Wipaire One particular Ton Cub STC. This synthetic reduction will ideally be improved Down the road. While in the intervening many years, Erickson has designed ribs and a number of other sections that are FAA PMA-ed for all rag-wing Pipers. Erickson was granted the STC for the complete-length leading edge slot in 1998. This slot helps protect the boundary layer of airflow at sluggish speeds. In addition to that, Erickson engineered a squared off wing and removed the suggestion bow giving the wing yet another six% floor area, increased the flaps which ends up in 44% additional flap location, and pushed the ailerons outward 23-inches to the sting of the wing. He phone calls it the “Prolonged Wing.” The squared wing provides about eight lbs to the initial Piper wing.

Including a slot towards the Extended Wing adds Yet another 9 lbs for each wing, however the improved security envelope from which to fly is properly definitely worth the trade-off. The flight traits of your squared-off and slotted wing, which Erickson calls the “Prolonged Slotted Wing”, is the main gain and emphasis with regards to selection of wings to incorporate with your Cub job. The Prolonged Slotted Wing is the best carrying out wing supplied by Dakota Cub. It’s got a a hundred thirty five-inch slot, a squared-off wing with 102-inch ailerons, and also a ninety.twenty five-inch flap. Dakota Cub also provides the conventional Cub wing along with a squared-off wing with no slot.
