核能推进航天器新方法

随着人类深空探测活动的开展,核能的空间应用作为一种发展前景很好的航天能源方式而受到关注.核裂变能的利用在地面已获得普及,在航天领域中的应用也取得一些进展,但核聚变能因其可控性的制约尚未解决,使得其空间应用存在很大的技术障碍.文章提出一种新的核聚变能的空间利用方法,利用核裂变点火、核聚变放能来实现核推进.核聚变材料在高温、高密度条件下发生核聚变反应,并使其能量储存在热载体中.通过选择合适的调制介质来调制辐射场和压力场,设置边界条件,最终达到直接推进航天器的目的.此外文章对核聚变能空间应用中的辐射防护技术也进行了讨论.

A new method of space propulsion by using nuclear energy

With the development of deep space probe,the space applications of nuclear energy are paid more and more attention as a kind of space energy with excellent prospect.The nuclear fission is quite popular in the ground applications and some progress has been made in space activities,but there are still technological barriers in the space applications of nuclear fusion because of its limited controllability.In this paper,we propose a new way of space applications of nuclear fusion energy.The spacecraft are fire...
