Use of Autonomous Inflatable Devices for Optimal Landing of Transportation Systems
Abstract
Today facing a huge issue on the concentration of space debris in near-Earth space. More than 15,000 debris have been recorded, and this represents a danger for current and future missions to space. A solution is to remove these spacecrafts from orbit. One way to do it is to use inflatable devices. During the descent in the atmosphere, the landing vehicle and its braking device are subjects to important perturbations, due to external environment. Thus, the inflatable device can be deformed, due to its flexibility, and the movement can become unstable. The purpose of this paper is to determine which angle of axis deviation during the landing is the safest for the transportation system. To do so, created a program that, for given initial conditions, and depending on the axis deviation and the type of ground during the landing of the transportation system, calculates the overload sustained. Then studied 14 different cases: 7 different axis deviation for two ground types (soft and hard), and extrapolated the results. These results showed that the safest landing is when the transportation system lands perpendicular to the ground, and the most dangerous one is when the axis deviation is the highest, resulting in bounces of the system. Can then conclude that the lower the axis deviation is, the safest the landing is.
