Dakota Cub’s Extended Slotted Wing

Flight safety is something all pilots communicate about. They live it, receive it, and always hope to pick out it in their day-to-day lives inside the aviation international. For the Super Cub fanatic, the Extended Slotted Wing from Dakota Cub offers pilots the opportunity to enhance their safety margin as well as boosting the climb performance of the aircraft.

Imagine flying your Super Cub at a high attitude of attack with the airspeed indicator analyzing 20 mph, then rolling into 60-tiers of financial institution and initiating a mountaineering spiral whilst deciding on a electricity putting this is much less than full throttle! That is the everyday exhibition that sells the Dakota Cub Extended Slotted Wing. The 2nd most pointed out great of this wing is the ability to have full flight manage authority at high angles of attack. No extra tender controls, plopping it down, or wing drop on stall.

Mark Erickson, the founder of Dakota Cub, commenced his mission in the 1990’s. All he wanted turned into a Cub rib. Nothing from Piper was to be had at an affordable fee and for the reason that Piper ribs were so fragile, he decided to construct his own. He implemented current-day technology to an antique Piper wing that was at first developed for the YL-14 liaison version of the J5C Cub. The YL-14 wing changed into a slotted wing. According to Erickson, there were only 14 of these plane built earlier than the cease of World War 2. They were in particular engineered for short take-offs of 100-toes and climbs with high angles of assault. There are most effective of those still within the air nowadays – one in Spain; the alternative in Nebraska. 먹튀검증

The Dakota Cub Extended Slotted Wing has several variances while in comparison to the unique Cub wing and the L-14 wing for that matter. Erickson revised the unique Piper US35B airfoil used for the L-14. He evolved a custom “T” shaped extrusion with the equal dimensions that once utilized in constructing a truss-fashion rib, is lighter, easier to work with, and extra strong than the authentic wing. Erickson received a STC for the brand new wing in 1993.

Erickson’s new rib best adds seven lbs to the burden of every original Piper wing. The new wing has been structurally tested to in access of 2,2 hundred lbs, but, the STC limits the gross weight to 1,750 lbs for the original wing or 2,000 lbs for those wings ready with the Wipaire One Ton Cub STC. This artificial reduction will optimistically be changed inside the future. In the intervening years, Erickson has designed ribs and many other components which can be FAA PMA-ed for all rag-wing Pipers. Erickson was granted the STC for the total-duration main area slot in 1998. This slot facilitates keep the boundary layer of airflow at sluggish speeds. On top of that, Erickson engineered a squared off wing and bumped off the tip bow giving the wing a further 6% floor area, multiplied the flaps which leads to 44% more flap vicinity, and driven the ailerons outward 23-inches to the threshold of the wing. He calls it the “Extended Wing.” The squared wing adds approximately 8 lbs to the authentic Piper wing.

Adding a slot to the Extended Wing provides another nine lbs per wing, but the extended safety envelope from which to fly is properly worth the alternate-off. The flight characteristics of the squared-off and slotted wing, which Erickson calls the “Extended Slotted Wing”, is the primary benefit and emphasis with reference to desire of wings to consist of in your Cub mission. The Extended Slotted Wing is the quality performing wing presented with the aid of Dakota Cub. It has a a hundred thirty five-inch slot, a squared-off wing with 102-inch ailerons, and a ninety.25-inch flap. Dakota Cub additionally offers the same old Cub wing and a squared-off wing with out the slot.
