摘要
应用气动力估算方法得到某小型无人机的纵向气动力数据;通过风洞试验和飞行试验对估算结果进行动态特性验证,并重点讨论了小型无人机的脉冲激励飞行试验验证。研究发现,选择飞行试验激励信号既要考虑小型无人机的特殊性,又要考虑信号的频谱特性;激励信号的选择为同类飞行测试提供了参考。
Longitudinal aerodynamic data of a small unmanned aerial vehicle （SUAV） were obtained though an aerodynamic estimation method. Wind tunnel test and flight experiments were carried out to verify the dynamic characters of estimation results, and dealt with the impulse excitation. As a result, the choice of excitation signal in flight-test is needed considering the SUAV＇s particularity and excitation spectral characters.
