# Aircraft Design for Sustained High-G Turns with Low Thrust > This patent describes an aircraft designed with unique wings, body, and engine placement to make tight, sustained turns with less engine power than traditional planes. - **Patent:** US 12735168 - **Original title:** Aircraft design and technology - **Granted:** 2026 - **Status:** Active - **Times cited:** 0 - **Field:** aerospace, mechanical, defense ## What it does Based on the abstract, this patent describes an aircraft designed for sustained high-G forces and high turn rates using less engine power. It achieves this by carefully balancing thrust and drag through a combination of "dual low thrust engines" and unique aerodynamic features. These features include a wing positioned laterally, horizontal and vertical tail surfaces, and engines mounted vertically below the fixed wing. Additionally, it incorporates "leading edge root extensions" (LERX) where the wing meets the fuselage, "dynamic slats" on the wing's front edge, and a "chine" along the fuselage nose. For example, the dynamic slats can extend to increase lift during a sharp turn, helping the aircraft maintain control and maneuverability at high angles of attack. ## What it does NOT cover - Does not cover aircraft primarily designed for high-speed straight-line flight without an emphasis on sustained high-G turns. - Does not cover aircraft that lack specific aerodynamic features like leading edge root extensions or dynamic slats. - Does not cover aircraft where the engines are mounted in different configurations, such as above the wing or within the fuselage. - Does not cover aircraft without a chine formed in the fuselage along its lateral sides at the nose. - Does not cover aircraft relying solely on high-thrust engines to achieve maneuverability, rather than balancing thrust and drag with low-thrust engines. ## The clever bit The cleverness lies in combining specific aerodynamic features like leading edge root extensions, dynamic slats, and a fuselage chine with dual low-thrust engines, strategically placed below the wing, to sustain high-G turns efficiently. This allows for extreme maneuverability without needing massive engine power by balancing thrust and drag. ## Real-world examples 1. Advanced fighter jet prototypes 2. Experimental research aircraft 3. Future unmanned combat aerial vehicles (UCAVs) ## Why it matters This design could be important for aircraft requiring extreme agility, such as advanced fighter jets or specialized research planes. By allowing sustained high-G turns with less engine power, it could lead to more fuel-efficient or longer-duration high-performance flight. It aims to improve maneuverability beyond what traditional designs offer, potentially impacting future military aviation or specialized aerial platforms. ## Frequently asked questions ### What does Aircraft Design for Sustained High-G Turns with Low Thrust cover?
