Aerospace Data Acquisition Application Case Study

Aerospace Data Acquisition Applications

VXI DAQ System for Aircraft Fatigue Testing

Customer Case

The customer required a turnkey data acquisition system complete with application software for a VXI-based structural test system for business jet aircraft. This VXI data acquisition system is used for static and dynamic structural testing on full-size corporate jet aircraft.

KineticSystems Case Solution

KineticSystems supplied a DAQ Director system for this application.

DAQ Director provides the software application for the system and the KineticSystems FOXI fiber optic interface provides the communication between the host PC and the VXI mainframe using a V122 PCI interface and a V120 Slot-0 controller. A V208 host ADC module, along with a V243 low-level signal conditioner and seven V241 high-level multiplexer modules handle approximately 600 channels of strain gage, thermocouple and pressure inputs. The system scans each of the channels at 100 samples per second.

Our SC20 bridge signal conditioner cards were not available when this system was purchased; therefore, third-party signal conditioners were used with their high-level outputs coupled to V241 multiplexer channels. In addition to the analog channels, the system monitors 16 isolated digital inputs and provides 16 form-C relay contact outputs. An IRIG time interface module was included to provide time stamping.
