Trip security is something all pilots discuss. They live it, accept it, and also constantly hope to select it in their daily lives in the air travel world. For the Super Cub fanatic, the Extended Slot Online Playstar Wing from Dakota Cub supplies pilots the chance to improve their safety and security margin along with boosting the climb performance of the airplane.
Visualize flying your Super Cub at a high angle of attack with the airspeed indication reading 20 miles per hour, then rolling right into 60-degrees of bank as well as launching a climbing spiral while choosing a power setting that’s less than top speed! That is the typical exhibition that sells the Dakota Cub Extended Slotted Wing. The second most discussed quality of this wing is the ability to have full flight control authority at high angles of strike. Say goodbye to soft controls, plunking it down, or wing decline on delay.
Mark Erickson, the owner of Dakota Cub, began his objective in the 1990’s. All he wanted was a Cub rib. Absolutely nothing from Piper was available at a sensible expense as well as considering that the Piper ribs were so fragile, he decided to develop his very own. He applied contemporary technology to an old Piper wing that was originally created for the YL-14 liaison variation of the J5C Cub. The YL-14 wing was a slotted wing. According to Erickson, there were only 14 of these airplane developed before the end of World War 2. They were especially crafted for short take-offs of 100-feet and climbs with high angles of assault. There are only 2 of these still in the air today – one in Spain; the various other in Nebraska.
The Dakota Cub Extended Slotted Wing has several variances when contrasted to the original Cub wing and also the L-14 wing for that issue. Erickson revised the initial Piper US35B airfoil utilized for the L-14. He established a custom “T” shaped extrusion with the very same measurements that when used in developing a truss-style rib, is lighter, simpler to deal with, and extra robust than the original wing. Erickson obtained a STC for the new wing in 1993.
Erickson’s new rib just adds 7 lbs to the weight of each original Piper wing. The new wing has been structurally checked to in access of 2,200 pounds, however, the STC limits the gross weight to 1,750 pounds for the initial wing or 2,000 lbs for those wings geared up with the Wipaire One Load Cub STC. This fabricated decrease will hopefully be altered in the future. In the intervening years, Erickson has actually created ribs and also lots of various other components that are FAA PMA-ed for all rag-wing Pipers. Erickson was provided the STC for the unabridged leading edge port in 1998. This port assists protect the boundary layer of airflow at slow-moving speeds. On top of that, Erickson crafted a squared off wing and also removed the suggestion bow giving the wing an additional 6% surface, raised the flaps which results in 44% even more flap location, and pressed the ailerons external 23-inches to the side of the wing. He calls it the “Extended Wing.” The settled wing adds regarding 8 lbs to the original Piper wing.
Adding a port to the Extended Wing includes another 9 pounds per wing, yet the boosted safety and security envelope from which to fly is well worth the compromise. The trip characteristics of the squared-off and slotted wing, which Erickson calls the “Prolonged Slotted Wing”, is the primary advantage and focus when it come to selection of wings to include in your Cub job. The Extended Slotted Wing is the most effective performing wing provided by Dakota Cub. It has a 135-inch port, a squared-off wing with 102-inch ailerons, and also a 90.25-inch flap. Dakota Cub likewise supplies the typical Cub wing and also a squared-off wing without the slot.
The Extended Slotted Wing is merely a safer wing. It permits a higher important angle of strike, slower delay speed, and practically gets rid of the unexpected loss of lift in contrast to a straight wing. It delays the splitting up of the air flow from the wing surface area, therefore aileron authority is preserved and in a lot of cases the only indication of a delay will certainly be a higher-than-normal price of suitable. This sensation permits the sink price of the aircraft on method to touchdown to be regulated by power alone making it possible for an extra specific touchdown factor without anxiety of a wing delaying or falling off on one side. The wing additionally has an enhanced roll rate due to the ailerons being reached the end of the wing.
If you intend to make the most of the Extended Slotted Wing on your Super Cub, after that it is recommended to set up a 3-inch equipment extension. The equipment expansion will permit the slow rate abilities of the wing to take complete effect upon landing. Bigger tires will attend to this also. Short gear paired with small tires will certainly lead to tail wheel first landings and also a take-off run that is longer than optimum due to the fact that it’s harder to attain that greater angle of attack.
Completion result of all this innovation is a Cub that has much better climb performance, far better sink control, slower landings, and a much greater margin of security. A wide-body fuselage from Airframes, Inc includes an extended body, as well as when combined with the larger control surface areas and the port, a pilot can fly at a 45-degree nose-up attitude, land at 25 knots, and also still have a wing that awaits the air.
