用于月球着陆场建造的集成传感器和土方车
Integrated Sensing and Earthmoving Vehicle for Lunar Landing Pad Construction
摘要：
减少建造着陆垫和防爆墙等项目所需的力量可能是降低建立月球定居点成本的主要驱动力之一。互锁驱动系统通过将铰接式道钉穿入地面并利用地面的自然强度来产生牵引力。道钉具有很高的拉力重量比，在松软、岩石和陡峭的地形中具有良好的机动性，操作节能，设计相对简单。通过以固定的间隔穿透地面，尖刺还可以原位测量各种地面特性，包括穿透阻力，温度和pH值。在这里，我们提出了一种带有联锁尖刺的轻型月球推土机的概念，该推土机使用刀片和松土器在短距离内松动和移动土壤，该系统可以在现场绘制地面特性，并利用这些信息建造着陆垫和防爆墙，以及以有针对性和有效的方式与地面进行互动。在地中海土壤上的试验表明，这一概念有望满足月球挖掘机的许多基本要求。为了更好地预测月球或火星环境中的性能，需要对相关土壤模拟物进行实验。
英文摘要：
Reducing the forces necessary to construct projects like landing pads and blast walls is possibly one of the major drivers in reducing the costs of establishing lunar settlements. The interlock drive system generates traction by penetrating articulated spikes into the ground and by using the natural strength of the ground for traction. The spikes develop a high pull to weight ratio and promise good mobility in soft, rocky and steep terrain, energy-efficient operation, and their design is relatively simple. By penetrating the ground at regular intervals, the spikes also enable the in-situ measurement of a variety of ground properties, including penetration resistance, temperature, and pH. Here we present a concept for a light lunar bulldozer with interlocking spikes that uses a blade and a ripper to loosen and move soil over short distances, that maps ground properties in situ and that uses this information to construct landing pads and blast walls, and to otherwise interact with the ground in a targeted and efficient manner. Trials on Mediterranean soil have shown that this concept promises to satisfy many of the basic requirements expected of a lunar excavator. To better predict performance in a lunar or Martian environment, experiments on relevant soil simulants are needed.
