To create next-generation large space radio telescopes operating in the short-wavelength region of the spectrum, it is necessary to ensure the high accuracy of the reflecting surface of the main mirror of the instrument and the high rigidity of the open reflector. The use of solid-state transformable petal mirrors is considered as one of the possible ways to solve emerging problems. The paper describes a new scheme for opening a petal mirror and presents the results of computer simulation of the deployment kinematics in the SolidWorks package.
