Controllable Pitch Propeller (CPP) Hands-On Training Simulator
Product Overview
A fully functional, industrial-grade Controllable Pitch Propeller (CPP) Educational Simulator designed for marine academies, maritime training institutes, and naval engineering laboratories. This unit provides a complete, hands-on demonstration of electro-hydraulic variable-pitch marine propulsion, allowing trainees to practice real-time blade positioning, zero-thrust calibration, and ahead/astern directional changes.
Key Features & Technical Specifications
Control System: Custom 24V DC indigenous control architecture powering all safety interlocks, status indicators, and solenoid valve logic for safe, low-voltage operation.
Hydraulic System: Integrated 220V AC single-phase hydraulic power unit (HPU) providing system pressure to the internal hub actuating cylinder.
Propeller & Hub Unit: Heavy-duty bronze multi-blade assembly mounted on a high-visibility, color-coded (green/red) hub housing the internal servo-cylinder, crosshead, and blade actuating mechanisms.
Dual Pitch Instrumentation:
Analog Display: Large 180 degree visual gauge with distinct Ahead, Astern, and Neutral (Zero-Thrust) sectors.
Digital Display: High-precision digital LED readout for exact blade angle verification down to decimal accuracy.
Mechanical Drive Train: Belt-driven propulsion shaft supported by rigid pillow-block bearings for smooth rotational demonstration.
Monitoring & Panel Layout: Heavy-duty industrial enclosure featuring LED indicators for Main Power, Pump Status, Directional State, and Line Voltage 220V AC, paired with manual toggle switches and a directional hydraulic lever.
Frame & Safety: Fabricated on a heavy-duty, powder-coated steel chassis with lockable caster wheels for easy mobility. Includes transparent acrylic safety guards over the lower hydraulic reservoir and motor housing.
