The Aeroload Simulation System (ALS) — sometimes referred to as a fin loader — is a general-purpose test instrument that can produce a wide range of rotary position motion, and/or active dynamic torque, to simulate loads that control surfaces experience during missile flight.  Many customers use this equipment in conjunction with a multi-axis Flight Motion Simulator, to complete a hardware test suite for their guidance system article(s).

Features of the Aeroload Simulation System

  • Torque-stiff flexible couplings allow actuator misalignments of up to 0.5° from orthogonal.
  • Actuator mounting plate includes large clearance hole, and features to adjust actuators to match test article diameter.
  • Modular construction, including System Control Console and Hydraulic Power Unit.
  • Actuators and torque transducers custom-matched to application requirements.
  • Rigid structure ensures operational fidelity.
  • Direct closed-loop control of position, torque, and “spring” modes of operation.Includes “cage” mode (smooth position-to-torque mode transition) for initialization.
  • Hydraulic snubbing, along with electronic and mechanical limits, to ensure payload, system, and personnel safety.

Options of the Aeroload Simulation System

  • Electric or Hydraulic drive actuators
  • Available in vertical (as shown) or horizontal axis UUT body orientation, and with single- or multi-axis actuators.
