FIELD: rocketry.
SUBSTANCE: proposed design and a manufacturing method for a sealed inlet are used in rocketry at construction of special fortification structures exposed to external loads, including hardening factors of nuclear explosions. Sealed inlet includes a hollow housing with connectors on end faces, electric wires, a fixing element is equipped in the front part of the hollow housing with a bearing diaphragm with holes for wires with heat-resistant insulation having a conical connection with the hollow housing and fixation by a locking ring. In the rear part of the hollow housing there is a metal-ceramic module consisting of a shell, current leads and a ceramic insulator arranged in the inner groove of the shell.
EFFECT: invention provides creating a sealed inlet able to resist superhigh loads from hardening factors.
