HWIL testing typically requires the implementation of a two-axis target motion simulator such as the Ideal Aerosmith Model 2452H. This system is configured with hydraulic actuator drives to ensure operational and performance compatibility with Ideal Aerosmith’s Model 2453H-ER Three-Axis Hydraulic Flight Motion Simulator (FMS). The two-axis configuration may be mounted to a separate base or to a base common to the three-axis system. The conventional TMS with a gimbal configuration provides azimuth and elevation target motion and all axes intersect at a common point to eliminate parallax with the missile seeker gimbal system located at the 3X FMS intersection of axes.
