Tamarack Aerospace Group unveils commercial active winglets

Tamarack Aerospace Group has announced at the annual National Business Aircraft Association Convention a new variant of their ATLAS Active Winglets specifically designed and scaled for commercial and military transport aircraft. The Commercial Active Winglet features several patented features which significantly enhance the performance of larger aircraft.

“This is a natural progression for Tamarack” said Nick Guida, Founder and CEO of Tamarack Aerospace. “We have been working on new technology for several years but have waited for the patents to mature. Building on the success of ATLAS for CitationJets, we are announcing some of our technologies that will bring the same benefits, and more, to air transport. The Commercial Active Winglet we are demonstrating at NBAA, has three of the new features that allow us to actively control wing loading, and thus efficiency.”

“First, the winglet can adaptively adjust its toe angle inwards and outwards according to flight conditions, maintaining optimization throughout the entire flight, rather than for only a single point in the sky. Second, the TACS (Tamarack Active Camber Surface) can now not only instantly turn off the winglet when loads are detected, but it can also droop to control wing loading or twist for peak efficiency. The two patents now act synergistically, such that the efficiency increases gained when they are both working together are greater than the sum of their individual contributions. Basically, we can actively control wing loading, wing twist, and with the speed of our actuators, even aerodynamic flutter. Lastly, the leading edge of the Commercial Active Winglet has a load alleviation device which prevents excess loads such as those experienced in a side gust event.”

Justin Ryan, President of Tamarack Aerospace, added “The benefits to Airlines and Military transport operators are pretty clear: our Commercial Active Winglet can deliver fuel savings, direct climbs to higher initial altitudes, reduced load and fatigue on the wings, greater range and new potential city-pairs, all without the excess structural weight of passive winglets. Instead of a passive winglet that is optimized for only one specific flight condition, the Commercial Active Winglet continuously adapts to provide operators with peak efficiency throughout the flight with a winglet that is 40% lighter. We have our fully functional engineering example of the Commercial Active Winglet at the show, booth 936, and we’d encourage people to come see this innovative technology for themselves.”
