System Integration Testing (SIT) is necessary to check and confirm aircraft systems’ correct integration and operation under simulated flight conditions. The System Integration Test Rig (SITR) is a mockup for developing and validating the system and software functioning with preproduction/production components installed on the aircraft. Therefore, SIT demands highly customized and complex test benches capable of performing Hardware-in-the-Loop (HIL) tests. The modular and flexible design of Q.series X DAQ systems, in combination with open interfaces for customized integration, ensures the possibility to adapt to any test case, reducing technical and schedule risks of the development and validation program.
The Iron Bird rig, also known as a Hardware-in-the-Loop simulator, is a full-scale mock-up of an aircraft. It is the primary test tool for the integration and endurance testing of all flight control and critical subsystems on the ground. Test data is gathered through various sensors, measuring displacement, strain, hydraulic pressure, and temperature, amongst others.
The main purpose of the Flight Control System (FCS) test rig is to verify and validate the primary (ailerons, rudders, and elevators) and secondary (spoilers, flaps, and slats) flight controls, including integrated testing of fly-by-wire flight control systems. Properties like displacement, acceleration, and strain characterize the mechanical behavior of the control surfaces.
Environmental Control System (ECS) or Air Management System is a generic term used in the aircraft industry for equipment providing temperature, humidity, ventilation, and pressure control to passenger/cargo areas. Temperature, pressure, and flow data acquired during ground testing are used to evaluate thermal comfort, pressurization, and cabin air quality.
According to statistics, landing gears play a major role in aircraft failure. A landing gear retraction test is an endurance test to validate the correct functioning of an integrated landing gear system under simulated aerodynamic loading over some time. Data is gathered for monitoring hydraulic system performance, landing gear operating speed, and shimmy vibration, among others.
The latest generation airplanes are known as More Electric Aircraft (MEA) due to their electricity usage for key aircraft equipment. Aircraft representative testing is paramount to optimizing and validating critical electrical systems. The Electrical System Integration Test Rig, also known as eSITR or Copper Bird, is a test bench to test and validate onboard electrical systems under simulated conditions.
