Tamarack Aerospace is in the final stages of FAA certification for the first commercially viable installation of its Active Technology Load Alleviation System (ATLAS), which allows wingtip extensions with winglets to be installed without increasing the load on the wing. The installation includes Tamarack Active Camber Surfaces (TACS) on the outboard portions of the trailing edges of the wings. The TACS automatically activate when additional load is put on the wing, such as during turbulence or maneuvers that increase G-load. The first STC for the system will go to the Cessna Citation 525 series: the CJ, CJ1, CJ1+ and M2. The system is already certified in Europe and is available for installation there.
We Fly: Tamarack’s Active Winglets
Key Takeaways:
- Tamarack Aerospace is nearing FAA certification for its Active Technology Load Alleviation System (ATLAS) on the Cessna Citation 525 series, which uses active camber surfaces to allow wingtip extensions with winglets without increasing wing load.
- The ATLAS system provides remarkable performance enhancements, enabling significantly faster climbs (e.g., to FL 410 in 34 minutes) and a 15-25 percent reduction in fuel burn.
- These improvements lead to increased payload capabilities, extended range, and improved lateral stability, along with a projected increase in the airplane's service life due to reduced airframe stress.
- Already certified in Europe, the system has an initial installation cost of $239,900 and is being discussed with other aircraft manufacturers for future applications.
