Unitech Composites partners with Tamarack Aerospace for production of active winglets

Unitech Composites, a Unitech Aerospace company and supplier of complex composite laminates, components and assemblies for the commercial aerospace and defence industry, agreed with Tamarack Aerospace to produce the composite content on their active winglets for the Cessna Citation Jet Series Aircraft.

Tamarack Active Winglets are the only aerodynamic technology on the market that can deliver up to a 20 percent fuel burn reduction and range increase without any structural reinforcement yielding significant time and cost savings.Tamarack Active Winglets are approved via  EASA and FAA Supplemental Type Certificate (STC) for installation on the Cessna CJ, CJ1, CJ1+ and M2 business jets.

“Unitech Composites is a value-added supplier, very responsive to our needs and has worked closely with us to rapidly optimize designs and streamline the manufacturing process.” said Brian Cox, Chief Operating Officer for Tamarack Aerospace.

“The opportunity to partner with Tamarack Aerospace, a fellow Idaho based company, on this industry shaping program is a great honor for Unitech Composites,” said Mark Withrow, Vice President and General Manager of Unitech Composites. “We are committed to the success of this program and are very pleased with its market acceptance and future trajectory .”  

Tamarack now has approval for the installation of its Active Winglets on the Cessna CJ, CJ1, CJ1+ & M2 in the US and all of Europe. Tamarack’s Active Winglet technology for the CJ and CJ1 provides a fuel saving and range increase of 20%, and fuel savings and range increase for both the CJ1+ and M2.

Aircraft wing efficiency is all about aspect ratio. Longer wings are more efficient for lift and have lower drag—think gliders. Winglets have the effect of increasing span, reduce drag from wing-tip vortices, and improve the lift distribution over the wing.

Tamarack Active Winglet System

ATLAS Active Winglets are designed for maximum aerodynamic efficiency without the compromises requisite of Passive Winglets. The key to the ATLAS Active Winglet system is the load alleviation aspect, which allows for the addition of a wing extension and a highly tuned winglet design while keeping the original wing structure.

Passive Winglets, on the other hand, require additional wing structure and weight to carry the additional wing loads. Tamarack’s innovative load-alleviating technology (ATLAS) allows Tamarack to aerodynamically “turn off” the winglet in specific conditions, thus dumping additional loads. Load alleviation enables a substantial increase in aspect ratio without the need for wing reinforcement (and added weight) or other compromises to the winglet design.

With the ATLAS Active Winglet system; load alleviation, wing extension and winglets achieve 3 to 4 times more fuel savings than Passive Winglets do. The ATLAS Active Winglet system increases aircraft stability and smooths out the bumps of inflight turbulence. The ATLAS system will also allow an increase in max zero fuel weight as well as provide better high/hot take off performance.
