Aircraft Flow Guide Body With Multi-Stage Pulsed Blowing

The patent applies periodic action by using pulsed blowing actuators that eject jets of air in periodic pulses rather than continuous steady flow. The control system activates and deactivates the blowing actuators in a periodic manner to create pulsed jets that delay or suppress flow separation. This periodic operation significantly reduces the total amount of air required compared to steady blowing while maintaining effective flow control on aerodynamic surfaces such as wings and tail planes.

The patent applies dynamics by using a dynamic control system that adjusts the timing, duration, and intensity of pulsed blowing based on real-time flight conditions. The control system dynamically modulates the pulsed jets to optimize flow control effectiveness across varying aerodynamic loads and flight regimes, ensuring that flow separation is effectively delayed or suppressed while minimizing air consumption. This dynamic adaptation maintains flow control efficiency despite the reduced air supply compared to steady blowing.

The patent applies segmentation by dividing the flow control system into multiple stages, where each stage includes blowing actuators and control elements that operate sequentially or in coordinated pulses. The multi-stage configuration allows the system to achieve effective flow control with reduced air supply by distributing the blowing action across multiple stages rather than requiring high-volume single-stage blowing. The segmentation enables more efficient use of available air while managing system complexity through modular stage design.
