摘　　要：在航路巡航阶段将部分间隔保持责任由管制员移交给飞行员,可在降低管制负荷的同时提升空域安全运行效率。针对新一代分布式空管模式,本机航空器基于交叉点到达时间将存在潜在冲突的目标航空器作为间隔控制目标机,构建交叉冲突中分别基于时间与空间的指定间隔值的自主间隔控制模型;以调整航空器机动飞行的校准空速作为航空器的自主间隔控制策略,通过控制本机航空器校准空速实现对两航空器间隔的有效控制。设置水平交叉冲突场景进行仿真对比实验,仿真结果表明了所提间隔控制策略用于分布式自主间隔保持的有效性及实用性。Transferring part of the responsibility for separation maintenance from the controller to the pilot during the route cruise phase can reduce the control load and improve the efficiency of airspace safe operation.For the new generation of distributed air traffic control mode,the own aircraft uses the target aircraft with potential conflict as the target aircraft for separation control based on the time-to-go of the intersection point,and builds an autonomous separation control model based on the specified separation values of time and space in the cross-conflict,respectively.Taking the calibrated airspeed of aircraft's maneuvering flight as the autonomous separation control strategy of the aircraft,the purpose of effectively controlling the separation between two aircrafts is achieved by controlling the calibrated airspeed of the own aircraft.Finally,a horizontal cross-conflict scenario is set up to conduct a simulation comparison experiment.Simulation results show the effectiveness and practicability of the separation control strategy in this paper for distributed autonomous separation maintenance.
