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.

地面监视雷达的设计和研制对研究界非常重要。这个 总部设在拉瓦尔的公司FLIR雷达在这一领域是众所周知的。他们的雷达必须在 强风的存在，因此它们对结构的影响将用亚音速来研究。 普莱斯-帕杜斯风洞安装在ETS的应用研究实验室中 控制、航空电子和气动伺服弹性LARCASE。 此外，该实验室在数值和计算领域发展出的经验和专业知识 将使用实验空气动力学。因此，由美国航空航天局设计和制造的四套雷达设备 公司将对FLIR雷达进行测试，以验证雷达需要的高速负载 做手术吧。将由FLIR雷达公司使用的设备将主要由2个雷达组成，将 安装在名为CLU-777摇摄/倾斜的定制(内部)支架上，安装在另一个摇摄/倾斜支架上，否则它们将不会 安装在平移/倾斜上。R20SS雷达比R6雷达大。这4套由组合组成 在雷达R6和R20SS之间，以及摇摄/倾斜。 以力和力矩的形式表示的载荷，在雷达设备上以数值估计的形式表示 最大速度为每秒45米(允许在风洞的最小气室中)有较高的 比现在可以在风洞中通过实际6个自由度的力/扭矩传感器测量的载荷更大的值 (平衡)。在空气动力学评估之后，必须设计一种新的自适应密封舱测试，并 制造的目的是为了能够以Paydoussis亚音速风的价格准确确定负载 隧道。LARCASE团队将为新的适应性测试的设计和制造做出贡献 腔，以及应将天平连接到模型的接口。此外，空气动力学数值模拟 将进行验证，以验证载荷的实验值。一项常见的研究 因此，将在ETS的FLIR雷达公司和LARCASE团队之间开展工作。
