Tamarack is positioned among the current aerospace innovators working to provide a realistic and sustainable future of flying. Today, industry discourse points toward a synthesized effort to take on the climate crisis, with experts in all fields looking to solutions. Tamarack has created the next-generation winglet, the Active Winglet, designed to reduce up to 33% of fuel consumption without compromising the structural integrity of a wing. And while this development in aerodynamics is an immediate carbon emission reducer, we know that this innovation is only as strong as the community belief to fly sustainably. This starts not only with Tamarack’s efforts, but with a combined effort from other key experts in weight, thrust, and fuels.

Many additional technologies have emerged in the past decade in the fight to limit carbon emissions and enable a clean and quiet future of flight. We have seen increased development in hybrid and electric engines, nodding toward a new kind of aircraft production entirely. And of course, one of the most buzzed-about developments has been the implementation of Sustainable Aviation Fuels (SAFs), which reduce carbon emissions up to 60% - this is the kind of fuel development Tamarack believes in. SAF, when combined with Active Winglets, can provide a turn-key solution the industry needs while proving that we work better when we work together. Tune into the 2020 NBAA GO Virtual Business Aviation Convention & Exhibition (VBACE) on December 3rd to hear Tamarack founder Nick Guida discuss this approach to sustainability.

SAF is much different than biofuels, and understanding the difference lies in understanding the molecular structure of each; biofuels, like ethanol and biodiesel, are sufficient fuel replacements in some respects. However, they are not pure hydrocarbons. SAF, on the other hand, have an identical molecular make-up to that of ordinary fuel, but have a lower impact on greenhouse gasses. Sustainable Aviation is, at a basic level, jet fuel produced synthetically from other hydrocarbon sources without using petroleum. Sustainable Aviation Fuel is, at a basic level, jet fuel produced synthetically from other hydrocarbon sources without using petroleum.

This fuel is produced in a separate plant (not a refinery), and mixed with any 1655 Jet A fuel. SAF is proven to provide the same performance and safety level as Jet A fuel without affecting jet maintenance needs. In addition, they emit less particulates, which reduces cirrus-clouding. SAF offers a 70-80% reduction in carbon emissions (net life cycle), however current regulations only allow for SAF blends. Thus, we get an average of 60% carbon emission reduction rate. However, if we add that rate to a business jet equipped with Active Winglets, we can create an additional 33% reduction in fuel overall.

Every day brings a new possibility to the industry, proving that we must work together to accomplish our sustainability goals. While this horizon might be some years in the distance, we can start envisioning a world where the availability and distribution of SAF is mainstream. For now, it should be an industry priority to establish an easy way to acquire SAF in the near future to implement with other sustainable technologies like the Active Winglet.
