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.
Active load abort system can reduce all actuator loads to a neutral state simultaneously
Redundant unload control system runs in concert with test load control
User definable loading schemes for both rate and unloading load profiles
Delivers both load limiting and overload protection


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

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.

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.

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.
