Test Article Safety Solutions

Achieve complete control over both planned loading and unintended unloading of multi-channel aerospace structural test systems. MTS load limiting and load abort technologies are deployed worldwide to protect lab personnel and one-of-a-kind structural test articles from uncontrolled or excessive forces in the event of power outage or test system interlock during testing.

MODEL COMPARISON

TECHNICAL OVERVIEW

The AeroPro Software safety solution features integrated feedback limits to provide a standard level overload or over-travel protection.

  • Establishes limits for test actuator output forces
  • Provides tracking error protection for control channels
  • Each input can be assigned independent upper/lower and inner/outer limits, which can be triggered by system-level actions


AEROPRO SOFTWARE BROCHURE

The MTS Passive Safety Solution provides a reliable, mechanical means for rapidly removing energy from single- and multi-channel test systems. It combines an MTS Series 297 Overload Protection Module and an MTS Model 289.11 Load Limiter Valve to create a highly stable two-stage valve system capable of responding quickly to unexpected pressure changes.

  • Stable, high-response, two-stage load limiter valve
  • One-piece, split and remote manifold configurations
  • Independently adjustable tension and compression bleed-down rates
  • Modular construction
  • Hardened steel cartridge valve design
  • Complements AeroPro software load limiting

The MTS Active Safety Solution integrates parallel FlexTest control systems, AeroPro software and a unique hydraulic manifold to provide comprehensive control over both planned loading and unintended unloading of multi-channel structural test systems.

  • Monitors the test system continuously to provide rapid, uniform reduction all actuator loads to a neutral state when needed 
  • Establishes load limits for actuator output forces
  • Programmable unloading schemes for both rate and unloading load profiles
  • Redundant primary and secondary FlexTest control systems
  • Advanced active load abort manifolds
  • Mechanical fail-safe system
  • Complements AeroPro software load limiting 

Both MTS active and passive load abort manifolds can be mounted directly to test actuators (locally), or be bracketed onto a free-standing frame (remotely) to avoid adding mass to the actuators. 

  1. Remotely manifold mounting on stanchions/racks
  2. Local manifold mounting on test actuator
