Abstract
The invention, which relates to the fields of a sneaking device antenna dome and a manufacturing method thereof, provides a composite-material pressure-resistant-structure rectifying antenna dome and a manufacturing method thereof, so that problems of large antenna dome weight, poor streamline type curved surface precision, poor anti-corrosion performance of dome and bolt connection, low reliability, poor interlamination water-pressure-resistant performance of dome body, and short service life can be solved. A housing has a streamline type curved-surface end cover structure; and an opening end of the housing is connected with a stem surface of a sneaking device in a sealing manner. A support structural member is in a horn shape; a large end of the support structural member is fixedly connected with the inner surface of the housing; and a small end of the support structural member is fixedly connected with the stem surface of the sneaking device. A fixed structural member is in annular shape; the external circumference of the fixed structural member is fixedly connected with the inner wall of the support structural member; the range of the included angle between the side wall of the support structural member and the centre shaft of the housing is from 40 degrees to 45 degrees; and the support structural member and the fixed structural member are arranged in an integrated manner. The composite-material pressure-resistant-structure rectifying antenna dome and manufacturing method thereof can be applied to the manufacturing field of the sneaking device antenna dome.
Description
technical field [0001] The invention belongs to the field of a submersible radome and a manufacturing method thereof. Background technique [0002] At present, with the survey of deep-sea resources and the needs of military use, the detection depth of the submersible is getting deeper and deeper, the cruising speed is getting faster and faster, and the overall performance requirements are getting higher and higher. The antenna shield installed on the submersible In terms of shape, it not only needs to perform the function of drag reduction and rectification, but also needs to meet the wave-transparency performance requirements of the antenna. [0003] The radome of existing submersible mostly is that metalalloy frame and radome shell are formed by screwing, and this kind of product weight is bigger. The radome shell and metal frame need to be released from the mold for subsequent assembly. Due to the poor rigidity of the radome shell itself, it is easy to deform after it i...
