Product Overview The rudder and tailplane are fundamental control surfaces that govern the stability and maneuverability of an aircraft. The rudder, mounted on the vertical stabilizer, provides yaw control — critical for crosswind landings, coordinated turns, and directional stability. The tailplane, also known as the horizontal stabilizer, manages pitch balance and trim, ensuring smooth climbs, descents, and level flight. Failure in either system can severely compromise safety, handling, and mission performance. To guarantee reliability, the actuators and hydraulic subsystems controlling these surfaces must undergo comprehensive functional, endurance, and performance testing before being certified for flight. The Rudder & Tailplane Test Rigs are specialized hydraulic benches engineered to replicate the demanding loads, pressures, and dynamic conditions experienced in real-world operations. These rigs provide an integrated platform for proof pressure validation, leakage detection, cyclic endurance testing, response measurement, and contamination monitoring. With independent benches for rudder and tailplane, dual-circuit hydraulic architecture, and upgrade options for automation and data acquisition, they form the backbone of OEM production lines, R&D facilities, certification labs, and MRO workshops worldwide. Why This Testing Is Critical • Safety: Control surfaces directly affect aircraft maneuverability and stability. A malfunctioning rudder or tailplane actuator could result in loss of directional or pitch control. • Certification Compliance: Aviation authorities demand exhaustive testing of flight control systems to meet international standards (FAA, EASA, DGCA, MIL/Aero). • Operational Reliability: Repeated cycles under real operating conditions ensure actuators can endure thousands of flights without failure. • Maintenance Assurance: Post-overhaul testing detects hidden leakage, sluggish response, or contamination issues before components return to service. • Cost Reduction: Identifying defects on the test rig rather than in the aircraft avoids expensive flight test rejections or in-service failures. Key Features • Independent Test Benches ▹ Separate rigs for rudder and tailplane actuators, allowing simultaneous or stand-alone operation. ▹ Modular design ensures easy integration into existing labs or hangar facilities. • Dual-Circuit Hydraulic Architecture ▹ Servo Pressure Regulator for precise, dynamic control of actuator response. ▹ Test Pressure Regulator for static proof and leakage testing. ▹ Enables seamless switching between functional and endurance tests. • Comprehensive Safety Systems ▹ Dedicated Dump Valve for rapid depressurization. ▹ System-1 and System-2 Return Valves offering flexible return routing. ▹ Over-pressure relief and emergency shutdown features. • Instrumentation & Sampling ▹ Main analog pressure gauge for immediate operator feedback. ▹ Pressure & return line sampling ports for contamination monitoring (ISO 4406 / NAS 1638). ▹ Expandable sensor suite: pressure transducers, load cells, displacement sensors, flow meters, temperature probes. • Operator-Friendly Control Panel ▹ Intuitive valve handles with OPEN/CLOSE markings for error-free operation. ▹ Clear separation of test, return, and dump controls to avoid cross-connection risks. • Upgrade Options ▹ Integration with PLC/SCADA systems for automated testing, interlocks, and programmable test sequences. ▹ Digital DAQ systems for logging, trending, and generating test reports. ▹ Inline particle contamination monitors for continuous fluid health checks.
