Challenge

The project objective was to engineer a mobile test rig capable of conducting controlled and highly repeatable leak testing of seals and pinned joints across aero engine components. The rig was designed as an autonomous diagnostic platform providing internal working medium preparation, automated test execution, and continuous parameter tracking throughout all test phases.

Solution

Proximo Aero engineered a compact, wheeled mobile cart integrating a complete compressed air circuit with an independent onboard power supply. The unit generates, conditions, and delivers process air under strict target pressures directly to the component under test. The rig incorporates precision measurement instrumentation, including electronic pressure regulators, mass flow meters, and pressure transmitters, driven by a dedicated control system for safe and repeatable execution. An integrated barcode reader automatically identifies test elements and loads matching test sequences, while an industrial HMI panel and panel PC give operators real-time visibility over test variables and subsystem states.

Scope of Work

Comprehensive engineering delivery from concept through on-site commissioning:

  • Mechanical and pneumatic engineering design paired with control system and automation architecture
  • Complete 3D CAD modeling and development of the manufacturing documentation package
  • Fabrication of the mobile cart chassis and integration of compressed air and internal power modules
  • Integration of precision instrumentation (pressure regulators, transmitters, flow meters)
  • Deployment of automated test execution loops with barcode part identification integration
  • Implementation of the HMI and panel PC interface, system calibration, and commissioning for leak validation routines

Outcome

The completed system delivers fast, repeatable leak testing across demanding production and maintenance environments. Its mobile footprint allows easy repositioning across testing bays, while automated control routines and barcode part tracking minimize operator involvement, enhancing process safety and data integrity. The unit serves as an autonomous quality assurance asset combining mobility, precision instrumentation, and automated inspection procedures.
