FACILITIES AND EQUIPMENT

The Crash Dynamics Laboratory provides a facility for research, testing and certification of aircraft and non-aviation components under dynamic impact (simulated crash) conditions. The state-of-the-art servo-hydraulic crash simulator reaches speeds of 81 km/h (50mph) with a 1500 kg (3300 lbm) payload and adjusts impact pulse peak profiles to match client’s needs up to 65 g’s (75 g’s with a 1000 kg (2200 lbm) payload). In addition to the sophisticated data acquisition system, NIAR uses a high-resolution, high-speed digital video system that captures 1000 frames per second. For surrogate occupants, Hybrid II, Hybrid III and EuroSID II anthropomorphic test dummies are used. This laboratory provides a secure environment for proprietary testing.
