The design and development of ground surveillance radars is very important to the research community. The company FLIR Radars based in Laval is well known in this field. Their radars have to operate very well in the presence of strong winds, thus their influence on their structure will be studied using the subsonic Price-Païdoussis Wind Tunnel that is installed at ETS in the Laboratory in Applied Research in Active Controls, Avionics and AeroServoElasticity LARCASE. In addition, the experience and expertise developed at this laboratory in the fields of numerical and experimental aerodynamics will be used. Thus, four sets of radar equipment designed and manufactured by the company FLIR Radars will be tested in order to validate the loads at high speeds at which the radar needs to operate. The equipment that will be used from FLIR Radars Inc. will be composed mainly of 2 radars that will be installed on a custom (in-house) support called CLU-777 pan/tilt, on another pan/tilt, or they will not be installed on the pan/tilt. The R20SS Radar is larger than the R6 Radar. The 4 sets consist of combinations between the radars R6 and R20SS, and the pan/tilts. The loads expressed in terms of forces and moments estimated numerically on the radar equipment for the maximum speed of 45 meters per second (allowed in the smallest chamber of the wind tunnel) have higher values than the loads that can be now measured in the wind tunnel by the actual 6 DOF forces / torques sensors (balance). Following aerodynamics estimations, a new adaptive chamber test has to be designed and manufactured in order to allow the accurate determination of the loads at the Price-Païdoussis Subsonic Wind Tunnel. The LARCASE team will contribute in the design and manufacturing of the new adaptable test chamber, and the interface that should connect the balance to the model. In addition, aerodynamic numerical validations will be performed in order to validate the experimental values of the loads. A common research work will thus be performed between the FLIR Radars Inc. and the LARCASE teams at ETS.
