Max Zero Fuel Weight Increase CJ2+ 400 lb. 38.2” The Passive Winglet Problem Winglets have been around for 100 years and work by increasing the wing’s aspect ratio, which increases aerodynamic efficiency (think gliders). All winglets to date have been passive winglets, and cannot adapt to changing wing loads. Passive winglets increase wing bending, especially during large gust events or high-G maneuvering, and as a result, require additional wing structure to protect the wing, but this adds weight. The Active Winglet Solution But what if a winglet could intelligently ‘turn itself off’ during load events and be optimized for peak efficiency the rest of the time? ATLAS does exactly that. Using load sensors, and a camber surface that can respond in fractions of a second, the Active Winglet can automatically control wing loading during load events. ATLAS is fully automatic, requires no pilot action, and functions autonomously from other aircraft systems. The result is peak efficiency without the need to add additional wing structure – and an Active Winglet that allows ‘bolt on’ installation. ATLAS Active Winglets consist of three main parts: • The wing extension • The TACS (the load alleviation element) • The winglet itself The patented combination of all three parts makes Active Winglets two to three times more efficient than passive winglets. Within the aircraft itself are five control and indication elements: • The ATLAS Control Unit (ACU) which senses loads • The two wing mounted TACS Control Units (TCUs) which are high speed actuators • The ATLAS cockpit annunciator • The ATLAS cockpit annunciator controller As the ATLAS Control Unit (ACU) in the aircraft senses increased loading, it commands the TACS Control Unit (TCU) to position the TACS to aerodynamically ‘turn off’ the Active Winglet. System operation is completely automatic. Failure modes are benign and the only required pilot action in the event of a failure is to slow to the indicated airspeed shown on the cockpit annunciator. ATLAS has been extensively flight tested with ice shapes (normal and asymmetrical), TACS positioned in all modes, and even with only one Active Winglet on the aircraft. At all times the aircraft control surfaces have authority for normal handling. Updated LED wingtip and tail strobes are included as part of the ATLAS installation kit. ACU TCU Cockpit Annunciator & Controller Wingtip Light Tail Strobe How ATLAS Works CJ3. Paris, TX to Paris, France. One Stop. Carrying two pilots, one passenger and loaded to max takeoff weight, the jet departed Paris, Texas flying 2,104 nautical miles to St. John’s, Newfoundland (CYYT). The flight had a 4 knot tailwind and flew at 376 knots true airspeed for 5 hours and 32 minutes. The total fuel burn for the first leg equaled 3960 pounds (107 gallons per hour block fuel burn). The St. John’s, to Paris Le Bourget flight, a distance of 2244 nautical miles, took 5 hours and 45 minutes flying at 373 knots true airspeed with a 17 knot tailwind. The total fuel burn for the transatlantic leg was 4210lb (108 gallons per hour block fuel burn). Fuel burn at maximum Mach number at Flight Level 450 has typically dropped from around 800lb/hr. to 700lb/hr. Combined with a faster time to climb and much quicker acceleration when leveling at cruise altitude, the fuel savings significantly extend the range of the CJ3. Testimonials "As a professional pilot, I must say that TAG's winglet- equipped CJ was impressive from takeoff at MTOW, to touchdown. The noticeably improved climb performance experienced through the flight levels is a testament to the success and effectiveness of Tamarack’s winglet technology. Fuel consumption to top of climb (TOC) at FL410 was only 560 lb (82 gallons) and just under 35 minutes, which is a big advantage over the winglet-less platform. "A recent flight from Carlsbad to Sandpoint was the first time I flew the ATLAS™ - equipped CJ on any kind of a normal or typical point-to-point flight. The airplane flies superbly with the ATLAS™. I frequently encounter airplanes and products that don't quite live up to their manufacturer's claims, but the ATLAS™ is everything that Tamarack claims, and more. Unlike the factory CJ, the ATLAS™ CJ smoothly and swiftly climbs to FL410.
