Description

Изобретение относитс к строительнь1м сооружени м дл астрономического оборудовани и может быть использовано в качестве укрытий, преимущественно оптических систем от внешних атмосферных воздействий и уменьшени светового фона при наблюдении за объектами, движущимис по произвольным орбитс1М со значительными угловыми скорост ми относительно точки сто ни оптической системы.The invention relates to building structures for astronomical equipment and can be used as shelters, mainly optical systems from external atmospheric influences and a decrease in the light background when observing objects moving along an arbitrary angular velocity relative to the optical point of the optical system.

Известен купол оптической системы, преимущественно астрономического телескопа, включающий опорную чаЪть, перекрывающие смотровое окно створки забрала с осью вращени , пересекающейс с осью вращени купола, приводы, створок и вращени купола, и снабженный внутренней поворотной створкой, установленной на оси створок забрала и имеющей самосто тельный привод вращени , причем смотровое окно выполнено в виде усеченного шарового сегмента С1.The dome of the optical system, primarily an astronomical telescope, is known, which includes a supporting part, a shutter that overlaps the viewing window with a axis of rotation intersecting the axis of rotation of the dome, actuators, doors and rotation of the dome rotational drive, and the viewing window is made in the form of a truncated ball segment C1.

В указанном куполе згицита оптической системы от фонового излучени и атмосферного воздействи осуществлена недостаточно полно, так как смотровое окно, образованное створками и оболочкой купола, имеет форму ша.рового двуугольника, вследствие чего в процессе работы оптической систеь«4 остаетс незакрытой часть смотрового окна, наход ща с за пределами поперечного размера светового потока (выходного зрачка) оптической систег глы.In the indicated dome of the optical system, the background radiation and atmospheric effects are not fully implemented, since the viewing window formed by the flaps and the shell of the dome has the shape of a wide lamb, and as a result, the optical system 4 remains uncovered part of the viewing window, outside the transverse size of the luminous flux (exit pupil) of the optical system.

Недостатком известного устройства вл етс то, что в р де случаев траектории наблюдаемого объекта распо20 лагаютс таким образом, что наблюдение необходимо вести через верхнюю часть дополнительного смотрового окна с переходом в зону смотрового окна, выполненного по форме шарового A disadvantage of the known device is that in a number of cases the trajectories of the observed object are located in such a way that the observation must be conducted through the upper part of the additional viewing window with a transition to the area of the viewing window made in the form of a ball head.

In such cases, it will be necessary to transfer the dome through 180 ° and the associated termination of observations of the object. During the transfer of the dome of the observed object may be

30 rub n. The purpose of the invention is to ensure the continuity of tracking an object and expanding the functionality of the system. This goal is achieved by the fact that the dome of the optical system, including a hemispherical shell with a main viewing window, is designed as a ball lug located in the zenith part of the dome, with an additional viewing window installed on the common axis of the outer and inner flaps, the main viewing window is symmetrical but relative to the zenith axis of the dome and combined with an additional viewing window, the axis of which is located perpendicular to the axis of the main viewing window. FIG. 1 shows a dome with closed flaps, a transverse section; in fig. 2 - the same, with open kami; in fig. 3 is a view along arrow A in FIG. 2. The dome of the optical system includes a visor 1, a hemispherical shell 2 mounted on a support ring 3. A viewing window 4 is made on the hemispherical shell. On the common axis 5 there is an outer flap 6 and an inner flap 7 ku of the floor. The visor has 1 domes with; mounted opening on axis 8, lying down outside the envelope. The viewing window is made in the form of two communicating zones. The first zone and the viewing OKHJI 4 is located in the zenith: part of the cupral, it has the shape of a spherical lagon. The lateral contours b of the second zone c are arranged in two parallel planar VTHXs, the shape of the bottom leaf corresponds to the first zone of viewing window 4, and the shape of zabrsha 1 corresponds to the second zone of viewing window 4. The device works as follows. After receiving preliminary information about the trajectory of the observed object, the visor 1 was removed by means of up-and-down drives to the position ensuring the operation of the optical systems without interference. If the object moves along a flat trajectory close to horizontal, then the inner flap 7 is retracted from the viewing window, 4, and the outer flap. B covers area a. At the same time, tracking of objects takes place under conditions of minimal influence of background and wind svetovbgo. If the observed object changes its trajectory, i.e. its movement became close to the zenith trajectories, the flap b goes into operation, reveals the necessary area and viewing window 4 and thereby ensures reliable continuous tracking of maneuvering objects throughout the celestial hemisphere and with relatively minimal rotation speeds of the dome, since the mode 180 ° dome transfer is not required. The base case is the B65 product, in comparison with which the proposed device provides continuous tracking of maneuvering objects throughout the celestial hemisphere, while reducing the dynamic loads on. drive 5 times and, consequently, the power of the drive rotation of the dome. The invention The dome of the optical system, including a hemispherical shell with a BbJM main viewing window, made in the form of a spherical twogon located in the zenith part of the dome, with an additional viewing window and installed on the common axis of the outer and inner flaps, so as to ensure continuity tracking the object 1 and expanding the functionality of the system, the main viewing window is located symmetrically relative to the dome's zenith axis and combined with an additional viewing window th window, whose axis is perpendicular to the axis of the main display window.
