摘要
探讨和分析了无人机采用双发固体火箭助推发射方案时存在的助推器同步性问题。并以某型无人机和火箭助推器为例，进行了火箭助推器的同步性仿真计算以及同步性对无人机发射段飞行稳定性的影响计算，分析确定了影响双发固体火箭同步性的显著因素，并就改善双发火箭同步性提出了相应的技术措施。计算结果表明，火箭助推器同步性对无人机发射段飞行轨迹及稳定性的影响在工程应用上是可行的。
In this paper, the synchronism problem of boosting rockets is discussed and analyzed while the UAV takes off by double solid boosting rockets. And using a certain model of UAV and boosting rocket as example, the simulated calculation of rockets' synchronism and flight steadiness of UAV in the launch posture is completed. Through analysis and calculation, the factors affecting rockets' synchronism obviously are determined and the relevant technical measures improving rockets' synchronism are provided finally. Meanwhile,the results of simulated calculation show that the effect of rockets' synchronism on flight steadiness of UAV in the launch posture is acceptable in engineering applications.
