摘要

基于磁流体力学模型

对Xe、He、C、N、O、Ne、Al、Ar等元素在激光辐照下的等离子体力学特性进行了研究

并且以Al元素为例

研究了不同波长情况下的靶材烧蚀速度以及烧蚀压力的变化趋势.结果表明:在相同入射条件下

除Xe外

He、C、N、O、Ne、Al、Ar这几种元素的烧蚀压力比较接近

并且各元素的烧蚀速度的情况也大体相同

这样从增加火箭的有效载荷的角度考虑

采用大气驱动模式将是非常有利的.另外数值模拟结果还表明

随着入射光波长的增加

靶材的烧蚀速度、烧蚀压力单调下降并逐渐趋于平缓

尤其是当入射光波长小于某一个值时

这个变化非常迅速.因此

如果单纯从入射光波长角度考虑

波长越短将越有利于产生更大的推力.但短波长激光被大气散射严重

造成极大的能量损耗.因而在实际应用时

应该根据飞行器所处的不同飞行位置合理选择驱动光波长.

Abstract

Based on a magneto-hydrodynamics model

the plasma characteristics for the elements Xe

Al and Ar are studied. And

numerical simulations were introduced to the relationship between the ablation-velocity and -pressure with the wavelength of the imported laser beam by using element Al as an example. These analyses show that under the same condition of the imported laser beam

the ablation-pressures and -velocities of He

Al and Ar are roughly equal

which means that the Air-breathing-Mode will be the profitable one to improve the effective load of the rocket. These simulations reveal that the ablation-velocity and -pressure of the target goes down and gradually tends to flatness with the increase of the imported laser wavelength. This change goes very rapidly when the wavelength is less than a certain value. If only considering the wavelengths of the induced laser beams

the shorter ones will be better to increase the thrust-force. But a laser beam with a shorter wavelength will be heavily scattered by atmosphere

leading to great energy loss. So in the practical application

the laser beam's wavelength should be chosen according to the different flying height of the aircraft.
