KEY: (I) View.
To reduce the size of the mirror on launch, its
upper part is
the form of leaves which can be turned on a joint 6 by the
hydraulic system and the power cylinders 7; in
of the mirror can be turned relative to its
addition, each leaf
own axis 8 (see View A).
After the leaves are turned to the working position relative to
hinge 6, they are unfolded to the working position relative to
axis 8 by hydraulic cylinder 9.
The dimensions of concentrators can reach 25-30 m in diameter
and create power for the power plant of up to 30 kW. An example
of solar concentrator mirror construction is shown in Fig. 2.67.
