Jigs & Fixtures – Assembly, Overhaul & Maintenance
Precision tooling is critical for reliable and repeatable assembly, disassembly, and servicing of modern combat jet engines. These jigs and fixtures ensure geometric accuracy, thermal tolerance, and operator safety across procedures.
🛠️ Turbine Blade Alignment Jig
Used during turbine rotor assembly to ensure precise angular placement and radial clearance of blades for optimal flow and vibration characteristics.
🛠️ Engine Split Mount Fixture
Supports engine casing halves in open position during overhaul procedures, allowing safe access to core modules like combustor, turbines, and shafts.
🛠️ Fuel Nozzle Calibration Jig
Holds fuel injectors in position for flow testing and spray pattern validation, enabling repeatable adjustment procedures during maintenance.
🛠️ Combustor Assembly Fixture
Used to hold annular liner segments and dome during welding or brazing, ensuring circularity and thermal gap tolerances are maintained.
🛠️ Rotor Balancing Cradle
Rotating support for turbine or compressor rotors during balancing. Allows real-time vibration analysis with trial weight placement.
🛠️ Variable Nozzle Adjustment Jig
Enables precise positioning of nozzle flaps during assembly, simulating thermal expansion and mechanical actuation conditions.
🛠️ Gearbox Test Bench Fixture
Modular mounting platform for driving and loading accessory gearboxes under simulated engine conditions. Includes torque feedback systems.
🛠️ Thermal Expansion Mock-Up
Replicates engine thermal envelope during subassembly alignment. Helps validate part clearances and simulate hot section growth.
🛠️ Electronic Harness Routing Jig
Defines wire pathing and bundling for complex engine harnesses. Ensures EMI shielding, bend radii, and connector clearances.
🛠️ Afterburner Duct Holding Fixture
Supports afterburner sections during repair, allowing safe inner wall inspection, welding access, and nozzle ring alignment.
