Dakota Cub’s Extended Slotted Wing

Flight protection is a thing all pilots discuss about. They Dwell it, accept it, and normally hope to pick it inside their day-to-day lives during the aviation world. With the Super Cub fanatic, the Prolonged Slotted Wing from Dakota Cub delivers pilots the chance to enhance their basic safety margin and boosting the climb performance of the plane.

Visualize flying your Super Cub in a substantial angle of attack Using the airspeed indicator reading 20 mph, then rolling into sixty-levels of lender and initiating a climbing spiral although picking a power location which is below full throttle! That’s the typical exhibition that sells the Dakota Cub Prolonged Slotted Wing. The second most discussed high-quality of this wing is a chance to have complete flight Command authority at higher angles of attack. No additional delicate controls, plopping it down, or wing drop on stall.

Mark Erickson, the founding father of Dakota Cub, started his mission during the 1990’s. All he desired was a Cub rib. Nothing from Piper was out there at an affordable cost and since the Piper ribs ended up so fragile, he made a decision to Make his have. He used modern-day-working day know-how to an outdated Piper wing that was originally created for that YL-fourteen liaison Variation with the J5C Cub. The YL-fourteen wing was a slotted wing. According to Erickson, there have been only fourteen of such plane designed prior to the close of Globe War two. They were specifically engineered for short consider-offs of 100-feet and climbs with superior angles of assault. You’ll find only two of those even now while in the air currently – a person in Spain; the opposite in Nebraska.

The Dakota Cub Prolonged Slotted Wing has various variances when compared to the first Cub wing along with the L-14 wing for instance. Erickson revised the first Piper US35B airfoil used for the L-14. He produced a personalized “T” formed extrusion Together with the identical dimensions that when Utilized in creating a truss-fashion rib, is lighter, less complicated to work with, plus more sturdy than the initial wing. Erickson received a STC for the new wing in 1993.

Erickson’s new rib only adds seven lbs to the weight of every initial Piper wing. The new wing has become structurally examined to in access of two,two hundred lbs, even so, the STC restrictions the gross fat to 1,750 lbs for the original wing or two,000 lbs for all those wings equipped Along with the Wipaire One particular Ton Cub STC. This artificial reduction will ideally be transformed Down the road. During the intervening decades, Erickson has made ribs and all kinds of other elements which have been FAA PMA-ed for all rag-wing Pipers. Erickson was granted the STC for the entire-length primary edge slot in 1998. This slot allows protect the boundary layer of airflow at gradual speeds. Along with that, Erickson engineered a squared off wing and got rid of the idea bow providing the wing an extra six% area spot, amplified the flaps which ends up in forty four% extra flap space, and pushed the ailerons outward 23-inches to the edge from the wing. He phone calls it the “Prolonged Wing.” The squared wing adds about eight lbs to the first Piper wing.

Introducing a slot for the Prolonged Wing provides One more 9 lbs per wing, even so the elevated protection envelope from which to fly is very well definitely worth the trade-off. The flight features in the squared-off and slotted wing, which สูตร เล่นสล็อต ยังไง ให้ได้กำไร Erickson phone calls the “Extended Slotted Wing”, is the principal edge and emphasis with regards to selection of wings to incorporate with your Cub project. The Extended Slotted Wing is the greatest executing wing supplied by Dakota Cub. It’s a one hundred thirty five-inch slot, a squared-off wing with 102-inch ailerons, and also a 90.twenty five-inch flap. Dakota Cub also provides the common Cub wing as well as a squared-off wing without the slot.

The Extended Slotted Wing is simply a safer wing. It permits a higher vital angle of assault, slower stall pace, and practically eliminates the unexpected lack of raise instead of a straight wing. It delays the separation with the air stream from your wing surface, Therefore aileron authority is taken care of and in several cases the only indication of the stall is going to be a greater-than-ordinary amount of respectable. This phenomenon lets the sink rate of the aircraft on method of landing to get controlled by electrical power by itself enabling a more precise touchdown issue with out panic of a wing stalling or slipping off on one facet. The wing also has an enhanced roll price mainly because of the ailerons being extended to the tip of the wing.

If you want to consider whole advantage of the Prolonged Slotted Wing in your Tremendous Cub, then it is recommended to setup a three-inch gear extension. The gear extension will permit the slow pace capabilities on the wing to just take comprehensive impact upon landing. Much larger tires will deliver for this too. Shorter equipment coupled with smaller tires will cause tail wheel to start with landings as well as a consider-off run that is for a longer period than best because it’s more challenging to realize that greater angle of assault.
