Existing technology for manufacturing high-speed zenith guided rocket radomes from quartz and glass ce
ramic materials is analyzed. The main production operations are provided for this technology, their disadvan
tages are demonstrated, and ways of improving the quality of components are considered.
Keywords: quartz ceramic, sitalls, radome.
Quartz and sitall radioparent radomes are used exten-
sively in domestic rocket building and therefore is desirable
to consider in detail the technology for manufacturing them.
Production technology for antenna radomes made of
quartz ceramic (Fig. 1) was known in the middle of the last
century [1, 2] and includes the following main operations:
melting of quartz glass, preparation of aqueous slips of
quartz glass, formation of preforms by slip casting in a po
rous mold, high-temperature firing of preforms, and machin
ing to the required level of technical characteristics, provi
sion shell sealing and their assembly with the rocket com
partment. The main properties of quartz glass slips, molded
and sintered preforms are presented in Table 1.
As noted previously, in spite of the fact that due to its
technological efficiency and unique physicotechnical proper-
ties quartz ceramic has found extensive use in various fields
of industry, the possibilities of using it in rocket technology
and aviation are limited due to a number pf disadvantages of
this material. High material porosity considerably limits its
application [3, 4]. At the same time technology providing
preparation of highly dense large objects made of quartz ce
ramic has not existed either in our country or abroad until
A lack of technology for preparing large objects (that are
antenna radomes) of highly dense quartz ceramic has a led to
a search for alternative materials and technology for resolv
ing the problem of assembling rocket radomes of aerodrome
and ship bases. An alternative technology is preparation of
radomes from glass crystalline materials (sitall grade
