Embodiment Construction

[0013] Referring to the accompanying drawings, when the window glass 2 is fixed to the fairing 1 in a certain way, it must not only be fixed reliably, but also have airtightness, so that the outside airflow should not enter the pod. In order to reduce weight, the fairing 1 is 2mm thick The spherical crown made of forged aluminum is knocked, and the window glass 2 is installed on the spherical crown. The infrared window has a large diameter and is located in the middle of the fairing 1. If flat glass is used, the overall aerodynamic performance of the pod will be affected. The use of spherical window glass 2 of equal thickness with a radius similar to that of fairing 1 can meet the aerodynamic performance requirements of supersonic flight. The matching inclined surface is matched so that there is no obvious height difference on the outer surface contacting the air; the bracket 5 is provided with a concave surface that can be tightly matched with the fairing 1, and the bracket 5...

Abstract

A cowlings window device of supersonic airborne nacelle used for detecting millitary targets, environment surveying, ocean resources exploring, etc. It consists of a cowlings and a window glass. A tray is used to combine the both parts by: having a concave surface to engage with the cowlings airtight and a declined surface to engage with the glass wnidow. It is reliably fixed and sealed tightly for flying condition of supersonic airplanes.

Description

1. Technical field [0001] The invention relates to a fairing window device of a supersonic airborne pod used in the fields of military target detection, environmental detection, marine resource survey and the like. 2. Background technology [0002] The fairing window device of the supersonic airborne pod is suitable for various aspects such as military target detection, environmental detection, and marine resource survey. At present, the fairing window of the airborne pod mainly has two types, integral type and assembled type. However, in the current assembled fairing window, when the large-sized spherical crown window glass is fixed to the fairing in a certain way, it must not only be fixed reliably, but also have airtightness, and must meet the flight conditions of the supersonic airborne pod. . There is still no relevant report on the fixing method of window glass being fixed on the fairing at present both at home and abroad. 3. Contents of the invention [0003] In o...
