摘要
为了解决航天器定点无损回收着陆及人员物资可控定点空投问题,研制了一种大型可控翼伞归航控制软件.本软件运行于大中型可控翼伞归航控制系统机载归航控制器上,采用分段归航控制算法和模块化软件设计结构,具有自动归航和人工遥控2种飞行模式,可对GPS提供的定位定向数据进行实时解码和运算,并自动输出控制信号操纵翼伞左右伞绳的收紧和放松,从而控制翼伞在指定区域着陆.该软件已经通过了分系统软硬件联合试验的验证.结果表明:该软件可以满足可控翼伞定点归航控制的需要,可广泛应用于精确定点空投及航天器、武器装备和运载火箭助推器定点回收着陆等领域.
To realize fix-point landing with lossless recovery for aircraft and controllable fix-point airdrop for person or materials, one kind of GNC （guidance navigation and control） software for big controllable parafoil had been designed. The obtained software, running at onboard control computer of GNC system for a big or middle parafoil, adopted a multi-segment control algorithm and modularized software structure. It could fly either in automatic mode or in manual remote mode. The present software could decode and conduct calculation based on the data provided by GPS and output control signals automatically to operate contracting or releasing both the right and left parafoil rope. This realized the landing to the area as predicted. The present software had been verified by hardware and software association test, whose results revealed that the present software met the requirement for fix-point recovery and landing of controllable parafoil. The present software exhibited promising application in precision airdrop, fix-point recovery and landing for aircraft, weapon, and launch vehicle of freight rocket.
