Purpose

This paper seeks to examine the application of active flow control using a valve system in a new hole-down-array (HDA-2p) wing design.

Design/methodology/approach

The active valve system functions by opening and closing various apertures to regulate airflow around the wing. A range of valve configurations, both open and closed, were examined and assessed alongside factors such as airspeed. The primary goal was to maximize efficiency. The aerodynamic characteristics of different wing setups were evaluated and enhanced.

Findings

The study demonstrates that using active flow control through valves on an innovative HDA wing design can potentially enhance the aerodynamic characteristics, notably improving aerodynamic efficiency.

Practical implications

The research carried out will lead to a deeper understanding of innovative wing designs along with the crucial topic of flow control, both passive and notably active. The data gathered from these studies will aid in the advancement of future wing designs, specifically regarding the application of flow control techniques.

Originality/value

The groundbreaking wing designs, featuring a HDA combined with active valve control, exhibit distinctive characteristics due to their nontraditional geometry and aerodynamic features. Inspired by natural elements such as the gaps between bird feathers, these vertical holes equipped with adjustable valves demonstrate significant potential for future advancements.
