Blended wing body aircraft with specific cabin dimensions
The patent US12065243B2 describes a blended wing body aircraft characterized by its unique design features aimed at optimizing aerodynamic performance and interior space. The aircraft includes an airfoil-shaped center body with an interior cabin that has a usable volume ranging from 1500 to 4500 cubic feet. The cabin's dimensions are defined by a maximum length and width, with an aspect ratio between 2 and 4. Additionally, the aircraft features a pair of wings extending from either side of the center body, resulting in a wetted aspect ratio between 1.9 and 2.7, which is crucial for enhancing lift and reducing drag.
Further claims detail the aircraft's structural specifications, particularly focusing on the normalized half-span values of the wings and the corresponding leading edge normalized heights. The design stipulates specific ranges for the leading edge normalized height based on the normalized half-span values, ensuring that the aircraft maintains optimal aerodynamic characteristics throughout its span. For instance, as the normalized half-span value increases from 0 to 0.4, the leading edge normalized height is defined within various specified ranges, allowing for precise control over the aircraft's performance. This innovative approach to wing and body design aims to improve efficiency and functionality in blended wing body aircraft.
