Idaho Patent of the Month – February 2024

Tamarack Aerospace Group, Inc. is soaring to new heights in aircraft innovation with its groundbreaking invention—an active winglet system that has the potential to redefine the efficiency and performance of aircraft. This recently patented invention introduces a dynamic approach to winglets, presenting a solution that not only enhances aerodynamics but also minimizes the structural impact on the aircraft.

While aviation has become an increasingly common approach to transportation, every flight has a significant impact on the environment. Each flight requires a great deal of fuel, even more so when the plane is met with wind resistance. Increases to aircraft efficiency can reduce the fuel required and reduce the impact on the planet. Tamarack Aerospace Group’s winglet design is just one example of the company’s approach to efficiency and sustainability.

Central to Tamarack’s invention is the concept of controllable airflow modification devices integrated into wing extensions. These devices, whether actively or passively responding to in-flight conditions, mark a departure from traditional fixed winglets. The ability to adjust these devices based on real-time data offers a significant advantage, optimizing aerodynamic forces without necessitating extensive structural modifications to the wing.

In a bid to revolutionize the certification process and reduce engineering costs, Tamarack’s active winglet is designed to keep spanwise section loads within originally defined values for a given wing. This unique feature eliminates the need for structural reinforcement, addressing a longstanding challenge in the aviation industry. Moreover, the controllable airflow modification devices play a crucial role in reducing the bending moment of the wing, contributing to increased overall service life and capacity.

The versatility of Tamarack Aerospace Group’s invention extends to its adaptability to different aircraft models. By configuring the controllable airflow modification devices based on flight data and specific aircraft requirements, the active winglet becomes a tailored solution rather than a one-size-fits-all addition. This customization not only enhances performance but also contributes to the aesthetics of the aircraft.

In essence, Tamarack Aerospace Group’s inventive leap with the active winglet system is poised to reshape the aviation landscape. With a focus on increased efficiency, reduced environmental impact, and a streamlined certification process, Tamarack is at the forefront of advancing aircraft technology. The patented active winglet system stands as a testament to the company’s commitment to innovation, pushing the boundaries of what’s possible in the dynamic world of aviation.
