New Data Acquisition Technology for Flight Motion Simulators

Tuesday March 10, 2015

ACUTRONIC USA, the world leader in multi-axis flight motion simulators, and Dynetics, a major provider of high-performance instrumentation solutions for test and evaluation of weapons systems, are pleased to announce an exclusive collaborative effort to integrate state-of-the-art data acquisition systems onto flight motion simulators. 

Traditionally, flight motion simulators include brush type sliprings through which data from a UUT (unit under test) is routed. At times, these sliprings introduce noise and/or attenuation to the signal of interest. In addition, due to their physical size, sliprings offer a limited number of signal lines as well as limited bandwidth of data transfer. Replacing traditional brush type sliprings with the Dynetics Modular Instrumentation System (MIS) significantly reduces or eliminates these problems. The MIS consists of a series of small round modules, approximately 2.5 inches in diameter, which are stacked together. Module selection is completely configurable and based on the specific data to be acquired from the UUT. All signals are converted to an optical signal, multiplexed  and sent through a fiber optic rotary joint (FORJ).

Signals routed through the Dynetics MIS have minimal noise, minimal attenuation, minimal cross coupling and significantly increased bandwidth, as compared to the use of traditional brush type sliprings. The data transfer interface in the FORJ is contactless, and therefore does not wear like a traditional slipring. In addition, a Dynetics MIS is significantly smaller and lighter than a traditional slipring, so its use results in lower axis inertias and higher axis accelerations on the flight motion table. More signal lines can also be provided in the same space occupied by a brush-type slipring. ACUTRONIC USA will exclusively include the Dynetics MIS in a new flight motion system or incorporate it into existing flight motion systems.
