Page 48 - Research Aircraft (RSRA) is designed to make high-accuracy, simultaneous measurements of all rotor forces and moments in flight. Physical calibration of the rotor force- and moment-measurement system when installed in the aircraft is required to account for known errors and to ensure that measurement-system accuracy is traceable to the National Bureau of Standards. The first static calibration and associated analysis have been completed with good results. Hysteresis was a potential cause of static...

Page 3 - Acree et al. (ref. 4). A summary of important features is given here. Figure 4 is a schematic representation of the staticcalibration method. A special calibration fixture replaced the rotor head, and the airframe was tied down by the landing-gear mounting lugs. Hydraulic cylinders applied static loads through cables and pulleys to...
Page 1 - Flight tests confirmed that the calibrated rotor-loadmeasurement system performs as expected in fight and that it can dependably make direct measurements of fuselage vertical drag in hover. Introduction MEASUREMENT of the forces and moments generated by a helicopter rotor in flight is a key research requirement of the Rotor Systems Research Aircraft (RSRA). The RSRA compound helicopter has a complete helicopter rotor system, as well as an independent wing and a fan-jet propulsion system, allowing...
