| Abstract: | In order to investigate aerodynamics and controlling capability of a grid fin with controlling system, and examine the capability of the rudder controlling system, a special test technique was developed in FL-24（1.2m× 1.2m）wind tunnel. A test platform for a full scale grid fin model was founded for the first time in high speed wind tunnel, including wind tunnel heavier load supporting device design, model protect device design, high sensitive wind tunnel balance development, model distortion measuring under wind load, and dynamic aerodynamic force test and data processing, etc. The test technique implements aerodynamics, rudder controlling system and structure integrative validation successfully. This work provided important test data for correlative specialty design and aviation experimentation of aircraft with grid fin empennage. |
