Variable Area Nozzle With Integrated Thrust Reverser Panels

The nozzle is divided into multiple independent movable panels (upper panels and lower panels) that can be individually actuated. Each panel can pivot about its own hinge axis, allowing the nozzle area to be adjusted in a segmented manner rather than as a single unit, enabling fine-tuned area control for different flight conditions.

The nozzle structure transitions from a fixed configuration to a dynamic one where panels can pivot and adjust their positions. The hinge connections and actuation systems enable the nozzle area to change dynamically in response to varying flight speeds, optimizing performance across subsonic, transonic, and supersonic regimes.

The movable panels serve multiple functions: they act as both the thrust reverser surfaces and the variable area control elements. The same panel structure that redirects exhaust for thrust reversal also controls the nozzle outlet area, eliminating the need for separate components and reducing overall system complexity.

The invention merges the thrust reverser mechanism with the variable area nozzle mechanism into a single integrated system. The upper and lower panels that pivot for thrust reversal are the same panels that control the nozzle outlet cross-sectional area, combining two functions into one unified structure.

Each panel is equipped with its own hinge axis and actuation system, allowing independent control of upper and lower panels. This segmented control architecture enables the thrust reverser and variable area functions to be operated independently or simultaneously, maintaining ease of operation despite the integrated design.

The hinge connections act as intermediary elements that facilitate independent rotation of each panel about its own axis. These hinge mechanisms serve as mediators between the actuation systems and the panel movements, enabling precise independent control while maintaining the integrated structure.
