Device and method for inflation and deflation of a seeker

Abstract

The invention discloses an air feeding and discharging device of a guide head. The air feeding and discharging device of the guide head is mounted on a shell (10) of the guide head and placed in an inner cavity of the guide head, and comprises outer sleeves (1), an air nozzle (2), handles (4) and air feeding heads (5). The air nozzle (2) is placed in the outer sleeves (1), the air nozzle (2) comprises a plug section and a ventilation section, the plug section is provided with an external thread, a flow guide groove is formed in the external thread, and an air nozzle inner cavity (202) is formed in the middle of the ventilation section. First steps (203) are arranged between the plug section and the ventilation section, gaps are arranged between the outer sleeves (1) and the first steps (203), and the outer sleeves (1) are provided with first sealing rings (6) at the gaps. An air through hole (201) is formed in the position, close to the first sealing rings (6), of the ventilation section, the air nozzle cavity (202), the air through hole (201) and the flow guide groove form an air feeding and discharging channel, and the handles (4) sleeve the air nozzle (2). The air feeding heads(5) are placed in the air nozzle inner cavity (202). The air feeding device has simple structure, convenient air feeding and discharging operation and good sealing.

Description

technical field [0001] The invention belongs to the technical field of precision-guided seekers, and more particularly relates to a seeker inflation and deflation device and method. Background technique [0002] The seeker is the core component of precision-guided weapons, and the advancement of seeker technology is an important symbol of the replacement of the entire precision-guided weapon. The seeker of precision-guided weapons is composed of position markers and electronic components. At present, developed countries in the world are conducting a series of scientific research and experimental design work to improve the optical, optoelectronic and radar seekers of precision-guided weapons. [0003] The seeker is a precision instrument and its internal components are easily disturbed by the external environment, which affects its performance. Especially for the seeker with an optical hood, such as a semi-active laser seeker, during the flight, the external environment When...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there is a lack of an inflation and deflation device for the seeker. The existing inflation and deflation device does not match the cavity of the seeker, and the matching and airtightness during the inflation and deflation process are poor. The air effect takes a long time and the airtightness is poor; and the existing inflation and deflation device is easy to protrude outside the seeker after installation or the protrusion height is greater than the specified value, which affects the aerodynamic shape of the seeker
