Presented in this paper are the results of theoretical studies of the rotational motion of a heated solid-state plate under the action of its coherent asymmetric thermal radiation. Thin plane-parallel plates are considered as objects, in which the coherence of thermal radiation is due to the interference effects. Time dependences of the plate rotation angle have been calculated under conditions that the plate temperature is kept constant, as well as in the mode of its radiation cooling. It has been shown that the coherence of thermal radiation can lead to the rotation and cooling rates of a plate with a certain thickness that can exceed the corresponding values not only for thicker plates, but for thinner ones as well. The numerical calculations have been performed for crystalline plates with a temperature of 350 K and the ambient temperature of 300 K.
