A fairing windshield with anti-rain function

Abstract

The invention provides a fairing wind shield with a rainproof function. The fairing wind shield comprises a laminated glass cloth plate, a glass fiber reinforced plastic plate and an O-shaped sealing ring. The glass fiber reinforced plastic plate is adhered on the upper surface of the laminated glass cloth plate; a dovetail groove is formed in the lower surface of the laminated glass cloth plate by means of machining, and the O-shaped sealing ring is compressed and assembled in the dovetail groove. The fairing wind shield has the advantages that bolt mounting holes in the glass fiber reinforced plastic plate and the laminated glass cloth plate and the dovetail groove in the lower surface of the laminated glass cloth plate are respectively positioned on two sides of each separation surface of each separation device after the fairing wind shield is mounted in place, and the glass fiber reinforced plastic plate and the laminated glass cloth plate are connected with the separation devices by connecting bolts which penetrate the bolt mounting holes; silicon rubber is further coated in portions between the laminated glass cloth plate and the separation devices and the heads of the connecting bolts, accordingly, wind shielding and rainproof effects can be realized for the separation surfaces by the wind shield which is coated with adhesive and treated and is provided with the O-shaped sealing ring, influence on normal separation of the separation surfaces can be prevented, and rainproof effects can be realized for the separation surfaces.

Description

technical field [0001] The invention belongs to the technical field of launch vehicle rocket body structure, and in particular relates to a fairing windshield used for a fairing separating device and having the function of preventing rain. Background technique [0002] Usually, the separation device of the launch vehicle fairing is equipped with a windshield to prevent the natural wind from entering the fairing from the butt joint gap of the longitudinal separation surface of the fairing during flight, causing the internal pressure of the fairing to increase or generate noise, thereby It affects the structural strength of the launch vehicle fairing and the payload inside the fairing. [0003] Commonly used windshields are generally made of laminated glass cloth and silicone rubber layers, such as figure 1 shown. figure 1 Among them, 1 is the separation device, 2 is the windshield, and 3 is the separation surface. The windshield is connected to the outside of the fairing t...
