华中机械研究所研制的,带4台发动机的水上自由飞模型于1980年试飞成功,翼展3.6m,机身长3.9m,正常起飞重量为36kg通过比例遥控设备可以控制模型各舵面、发动机风油门及测试程序开关。模型与真实飞机保持几何、质量、运动过程、拉力、升降舵效率等相似,另外模型试验水域的波浪谱应模拟便直实飞机适飞海域的海况。模型内装有多种传感器、记录器、控制线路以及各种电源等,其总重控制在23kg以内,可以综合测试水上飞机的安定性、操纵性、飞溅、水阻力、断阶处的着水撞击、机身起降过种中的砰击、纵向速度的变化及耐波性等。
The Huazhong Machinery Research Institute developed a 4-engine waterborne free-flying model that successfully flew in 1980 with a wingspan of 3.6m, a fuselage length of 3.9m and a normal take-off weight of 36kg. The remote control device can control the various control surfaces of the model and the engine Wind throttle and test program switch. The model is similar to the real aircraft in terms of geometry, mass, movement, tension, elevator efficiency and so on. In addition, the wave spectrum in the model test waters should simulate the sea conditions of the FIT aircraft. The model is equipped with a variety of sensors, recorders, control circuits and a variety of power sources, the total weight control within 23kg, you can comprehensively test the seaplane stability, maneuverability, splashing, water resistance, , The body took off and landing in the slamming, vertical speed changes and wave resistance.
