The paper presents the experimental investigation of the aerodynamic interaction between a helicopter model and a ship model with a simplified geometry. In the first phase of the experiment, a series of wind tunnel tests were carried out in order to study the flow features on the flight deck for several wind conditions, without the presence of the helicopter. Pressure measurements and Particle Image Velocimetry surveys were performed to assess the effect of wind velocity and direction on the flow field in the landing region over the ship deck. Moreover, the effect of the Atmospheric Boundary Layer was investigated. In the second phase of the experimental campaign, a helicopter model was positioned in a series of points representative of a typical stern landing trajectory and a vertical descent above the landing spot. The landing maneuver was performed in three different wind conditions, including no-wind, head wind and wind blowing from port side of the deck. The rotor loads and moments were measured by means of a six-axis balance for all test points. The use of different measurement techniques in the present experiments provides a comprehensive database suitable for the study of the rotor-ship aerodynamic interaction. Additionally, the experimental results are used to develop an identification algorithm to be incorporated into the flight simulator environment to capture the effect of ship airwake on the rotor loads during shipboard operations.

本文介绍了直升机模型和具有简化几何形状的船舶模型之间的气动相互作用的实验研究。在实验的第一阶段，进行了一系列风洞测试，以研究在没有直升机的情况下多种风况下驾驶舱的流动特性。进行了压力测量和粒子图像测速调查，以评估风速和风向对船甲板着陆区域内流场的影响。此外，研究了大气边界层的影响。在实验战役的第二阶段，将直升机模型放置在一系列点上，这些点代表典型的船尾着陆轨迹和着陆点上方的垂直下降。着陆操作是在三种不同的风力条件下进行的，包括无风，逆风和从甲板左舷吹来的风。通过六轴天平测量所有测试点的转子负载和力矩。在本实验中使用不同的测量技术可提供适用于研究旋翼-空气动力学相互作用的综合数据库。此外，实验结果还用于开发一种识别算法，该算法将被整合到飞行模拟器环境中，以捕获舰载操作期间舰载空中苏醒对旋翼负载的影响。在本实验中使用不同的测量技术可提供适用于研究旋翼-空气动力学相互作用的综合数据库。此外，实验结果还用于开发一种识别算法，该算法将被整合到飞行模拟器环境中，以捕获舰载操作期间舰载空中苏醒对旋翼负载的影响。在本实验中使用不同的测量技术可提供适用于研究旋翼-空气动力学相互作用的综合数据库。此外，实验结果还用于开发一种识别算法，该算法将被整合到飞行模拟器环境中，以捕获舰载操作期间舰载空中苏醒对旋翼负载的影响。
