Recent wind-tunnel tests at the NASA Langley Research Center National Transonic Facility used high-pressure bellows to route air to the semispan model for evaluating aircraft circulation control testing techniques. The introduction of these bellows within the sidewall model support system impacted the performance of the sidewall mounted force measurement system. A capability has been developed to facilitate system-level calibrations that characterize the performance of the force measurement system under influence of static pressure tare and thermal effects. From the highest system-level perspective, the aerodynamic research being conducted using this system would benefit from a system-level calibration at conditions that most accurately simulate testlike operating conditions. Detail is given on the recent improvements and design modifications to improve performance and calibration of the system as well as recommendations for future improvements. Experimental data from recent testing using the force measurement system are presented, with the results supporting the necessity for future system enhancements to improve system performance.
