ZA003 Aircraft Landing Gear (Retractable) Training System School Training Bench School Laboratory Equipment Educational Aircraft Trainer1. Must feature an authentic or airworthy-equivalent aircraft landing gear assembly mounted on a heavyduty, mobile steel frame with clear operational visibility of all moving linkages.
2. Includes functional mechanical linkages, main strut assembly, wheel/brake unit, up-and-down lock mechanisms, and gear door synchronization linkages without requiring disassembly.
3. Driven by a dedicated, self-contained hydraulic power unit (HPU) or manual hand pump specifically calibrated for gear extension and retraction cycles.
4. Must feature an emergency extension system (mechanical manual release, emergency crossover valve, or free-fall mechanism) to demonstrate emergency landing gear deployment during primary hydraulic failure.
5. Equipped with an aircraft-style control panel featuring a multi-position gear selector handle (UP/DOWN), warning horn/annunciator, and standard 3-green / 1-red status indicator lights.
6. Integrates safety squat switches (weight-on-wheels interlocks) and limit microswitches to demonstrate electrical lockouts preventing accidental gear retraction on the ground.
7. Equipped with integrated pressure gauges, cycle counters, and sensor tap-points (e.g., actuation pressure transducers, travel time / stroke position sensors) to measure extension/retraction response rates, pressure drops, and system latency for research and troubleshooting analysis.
Heavy duty frame with lockable swivel casters, protective clear acrylic safety guards around pinch points, emergency cut-off switch, and over-pressure relief protection.
