Large-scale structures should be delivered to orbit in a transport tightly packed form, allowing their transformation from a folded state to an expanded one. The very procedure of deploying the structure occurs under the influence of force actuators. In order to avoid dynamic loads affecting the elements of the transformed system, it is necessary to use actuators that operate without impact and have a relatively small mass. It is advisable to use an actuator with an active element made of titanium nickelide material with a shape memory effect. For these active elements, the control effect is the temperature field. The phase transformations of the titanium nickelide material are highly sensitive to temperature changes, which necessitate its precise control.
Zimin et al. (Fri,) studied this question.
