Intention of the Project Activity To design a hydraulic system that enhances the performance, efficiency, and safety of aircraft control mechanisms, ensuring compliance with aerospace standards.

F. Introduction Aircraft control surfaces, such as ailerons, rudders, and elevators, require precise and robust actuation systems. This project addresses the challenges of designing hydraulic systems, including weight optimization, fluid dynamics, and system redundancy, by leveraging modern design principles.

Initial Thinking (about the Problem): The primary issue is achieving a balance between system efficiency and redundancy to ensure reliability without excessive weight or complexity. Previous studies highlight the need for enhanced control response times under varying flight conditions.

G. Methods

Idealization: Simplified models of control surface dynamics were developed, assuming ideal fluid flow and minimal energy losses.

Instruction (Set): Calculate control surface force requirements. Design hydraulic actuator dimensions based on load analysis. Select appropriate hydraulic fluids for temperature and pressure ranges. Simulate system performance under various flight conditions.

H. Results & Discussion The designed system achieved a 20% weight reduction compared to conventional systems while maintaining performance. Simulations confirmed that response times meet aerospace industry standards. Redundancy was incorporated using dual actuators to enhance safety.

I. Conclusion, Closing Remarks, Recommendations The study demonstrates the feasibility of optimizing hydraulic systems for aircraft control surfaces by focusing on weight, performance, and reliability. Future work should explore integrating electronic control for further efficiency gains.
