Embodiment Construction

[0008] The present invention will be further described in conjunction with accompanying drawing:

[0009] As shown in the figure, a base (2) is provided at the lower part of the load (1), and the outline of the load (1) is similar to that of the base (2), leaving a gap not greater than 1 mm between them. An air chamber (3) is connected to the lower part of the base (2), and the base (2) is connected to the air collecting chamber (3) through an air guide hole (4). Two symmetrical air inlets (5) are arranged on both sides of the gas collection chamber (3), and the entrance of the air inlet (5) is connected with the outside of the fairing (7), and the entrance of the air inlet (5) is provided with With automatic opening and closing cover (6)

[0010] In a specific implementation process, the sensor (1) is directly installed in the base (2), and the base (2) provides good support for the sensor (1). When the sounding rocket produces excessive acceleration during launch or maneuv...

Abstract

The invention provides a rocket-borne sensor damping device applicable to the field of atmospheric exploration or astrophysics research for experiment research through a sounding rocket. The device mainly comprises a base, an air collecting cavity, an air guide hole, air inlet channels and plugging covers, wherein the contour of the base is similar to that of a sensor, and a gaps of not greater than 1 mm is reserved between the base and the sensor; the base is connected with the air collecting cavity through the air guide hole; the symmetric air inlet channels are arranged on two sides of the air collecting cavity; when the flight acceleration of the rocket reaches a set value, the plugging covers at inlets of the air inlet channels are opened, external air is compressed by the air inlet channels, enters the air collecting cavity and reaches the lower part of the base through the air guide hole, a layer of air film is formed in the gap between the base and the sensor, and the aim of damping the sensor is achieved. The device is simple in structure, easy to implement and good in actual effect.

Description

a technical field [0001] The invention relates to an rocket-borne sensor damping device, which can reduce the vibration of the sensor carried on the sounding rocket during rocket launch or maneuvering through its internal structural characteristics and special mechanism settings during the ground launch and flight of the sounding rocket. The vibration caused by the action can achieve the purpose of protecting the sensors and other equipment carried by the sounding rocket. It can be used in the field of atmospheric detection or astrophysics research. Two background technology [0002] A sounding rocket is a special vehicle that only carries scientific instruments for suborbital flights. Sounding rockets are generally uncontrolled rockets, which have the advantages of simple structure, low cost, and convenient launch. It is more suitable for temporary observation of short-term special natural phenomena (such as aurora, solar eclipse, solar eruption, etc.) and continuous obser...
