Modeling of a Tethered Testbed for a VTVL Vehicle

Figure 12

EAGLE’s trajectory 1 (in yellow) and the three ropes (fixed at the lander and led to the supporters). (a) 3D view of the motion. (b) view of the motion of EAGLE, where in-plane motion can be better visualized, with the lander that has to generate a force towards (in red). (c) view of the motion of EAGLE: given the motion and the contributions almost identical of rope 1 and rope 2, it is possible to see that the component of the force (in red) is very small compared to the - and - components. (d) view of the motion of EAGLE, where again rope 3 generates a pulling force on EAGLE, as visible from the component in red (showing the force that EAGLE has to generate).
