The primary objective of this project is the domestic design, development, and verification of the directional control valve utilized within the hydraulic systems of current aircraft, which is presently procured as an off-the-shelf imported product. The directional control valve is a critical system component responsible for directing fluid flow within the hydraulic system of an unmanned combat aerial vehicle (UCAV).

Within the scope of the project, prospective candidates will create a national valve design, taking into account the mission functions and system requirements of the existing imported product. Through this initiative, the ultimate goal is to reduce foreign dependency, enhance domestic manufacturing capabilities in critical subsystems, and establish a foundational framework for the domestic development of similar hydraulic components in future projects.

Criteria and Expectations

• A strong interest in designing valve systems capable of controlling hydraulic fluid direction and operating at the specified working pressure and flow rate values defined for UCAV hydraulic systems.
• The capability to develop designs that are fully compatible with existing system interfaces (connection points, mounting surfaces, and hydraulic ports) while ensuring ease of maintenance, assembly, and disassembly.
• Demonstrated competence in evaluating part geometries for manufacturability and preparing technical drawings, geometric tolerancing, and surface roughness specifications.
• The ability to select materials suitable for hydraulic system operating conditions (pressure, temperature, and fluid compatibility), with careful consideration of corrosion resistance and sealing performance.
• Comprehensive knowledge of sealing elements, CNC machining processes, precision tolerancing, and surface treatment requirements.
• The capability to execute verification processes—such as pressure resistance, leakage/sealing integrity, flow-pressure drop performance, and repetitive cyclic testing under operating pressure—and to compile the corresponding technical documentation and reports.
