Which aircraft primarily incorporates advanced aerodynamics in its design?

The X-29A is notable for its incorporation of advanced aerodynamics, particularly through its unique forward-swept wing design. This innovative configuration allows for enhanced maneuverability and stability at high speeds, while also improving performance at lower speeds. The forward-swept wings used in the X-29A help to delay airflow separation, resulting in better lift characteristics and overall efficiency.

Additionally, the X-29A was used to test various aerodynamics concepts and technologies, including active control systems that enable the aircraft to handle the complexities that come with its unconventional wing design. This made it a key platform for research in advanced aerodynamics, contributing significantly to the understanding of how such designs can be utilized effectively in future aircraft.

In contrast, the B-1B, XB-70, and XB-15, while they incorporated some aerodynamic advancements, do not exemplify the same level of innovation or focus on advanced aerodynamic principles as the X-29A. The X-29A stands out in its role primarily dedicated to exploring and validating these cutting-edge aerodynamic techniques.
