Analysis of existing radioparent refractory materials, composites and technology for creating high-speed rocket radomes. part 1. analysis of the level of property indices and limiting possibilities of radioparent inorganic refractory materials

Abstract

Radioparent materials that exist in the world, that may be used in the production of the radome of high-speed zenith guided rocket fairings are analyzed. The main physicotechnical indices are provided for these materials and the future for their application in radome production is indicated.

Various types of ceramics used in radome: A review

“…Comparison of drag for di erent nose shapes of the radomes is shown in Figure 2 [7]. Based on the wall electrical thickness, radomes are divided into thin-walled or half-wave radomes, and single and multilayer (two-layer or three-layer) radomes [2]. Conventionally, the radome is designed to be a single wall structure in which wall thickness is equivalent to an electron thickness of 1/2 wavelength.…”

“…Multilayer broadband designs, known as A-; B-, and C-sandwich structures, have been proposed to solve this problem [8]. As shown in Figure 3, the radome wall structure greatly determines the use of the de ned frequencies or broadband (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) wave transmission, and half-wave wall structure is used for the de ned frequency application [9]. The most commonly used and reported broadband radome wall structure consists of A-sandwich, C-sandwich, and multilayer.…”

“…A radome head not only protects the antenna section from the air ow and aerodynamic disturbances, but also determines the properties of a missile and its homing accuracy and receives the major forces and thermal loads during a maneuver. In addition, a radome allows the electromagnetic waves to pass through [1,2]. Radomes must be able to resist any real reaction that may emerge during an operation and must keep their strength and engineering properties intact [2].…”

“…In addition, a radome allows the electromagnetic waves to pass through [1,2]. Radomes must be able to resist any real reaction that may emerge during an operation and must keep their strength and engineering properties intact [2]. Therefore, a radome is used as a structural part to protect a radar unit while having the least interference in its electrical performance [3].…”

“…In terms of shape, radomes are classi ed as conical-spherical, ogival, or at radomes [2]. The most common nose shapes are conical, tangent or secant ogive, elliptical or hemispherical, power series, parabolic series, Haack series, or Von Karman.…”
