Description

Air inflation rigidization false target for space calibration

Technical Field

The invention belongs to the field of camouflage technology/false targets, and particularly relates to an inflatable rigidized false target for space calibration.

Background

In the modern space environment, how to calibrate and even perform a certain test on a space target is an important subject in the space military field. Therefore, research into how to observe and even experiment a spatial target has received attention in recent years. The space inflation false target means that the realization form of the false target is through inflation forming, and the false target can replace other high-value targets (such as satellites) as the cooperative target of observation and experiment after being unfolded and formed in the space.

The space inflatable false target is a false target form mainly adopted in the space, and mainly has the characteristics of similar appearance after being unfolded, light weight, small volume after being compressed and folded and low cost.

However, the conventional inflatable decoy has certain limitations, namely, if the decoy keeps the shape by the pressure of the internal inflation gas, the decoy is limited by the internal gas, and when the internal gas leaks, the decoy cannot keep the shape; if the shape of the inflatable false target is maintained by the internal supporting mechanism, the inflatable false target contains a rigid part inside, and new fragments and garbage are easily generated in the space. Thirdly, the posture of the traditional false target is relatively high in cost, the shape of the false target is maintained by the inflatable false target through magnetic stripe mode skills, and the uniaxial stability of the false target can be realized.

Disclosure of Invention

The invention aims to provide an inflatable rigidization false target for space calibration, which solves the problem that the traditional inflatable false target is easy to generate fragments in space.

The technical solution for realizing the purpose of the invention is as follows: an inflatable rigidization false target for space calibration comprises a flexible skin layer, an identification layer, a gas interface, a plurality of radial reinforcing ribs and a plurality of latitudinal reinforcing ribs; wherein flexible skin layer is spherical after strutting, and a plurality of radial strengthening rib and a plurality of latitudinal direction strengthening rib pass through gluey evenly distributed at the outer wall of flexible skin layer, and flexible skin layer, a plurality of radial strengthening rib and a plurality of latitudinal direction strengthening rib outer wall spraying sign layer, gas connector and flexible skin layer pass through the sticky connecing and communicate with each other.

Only one of the radial reinforcing ribs or the latitudinal reinforcing ribs is made of a magnetic material, and the other one is made of a non-magnetic material.

The reinforcing ribs made of magnetic materials are magnetized steel strips.

The reinforcing ribs of non-magnetic material comprise two reinforcing rib protective layers and a reinforcing rib stiffening layer sandwiched between the two reinforcing rib protective layers.

Compared with the prior art, the invention has the remarkable advantages that:

(1) the flexible bag body and the semi-rigid reinforcing rib form the novel space garbage in the space.

(2) The self-destruction air bag is made of flexible and semi-rigid materials, does not contain rigid parts inside, does not generate fragments in space, and can be lowered to the atmosphere for self-destruction within a certain time according to design.

(3) The optical coating and the radar coating are provided, so that the observation by a ground radar or a space camera can be guaranteed.

(4) The magnetic strip is used for simple passive control of the posture (through the earth magnetic field), and the single-axis stability of the false target is guaranteed.

(5) An inflatable unfolding structure is adopted, and the whole false target is supported by the semi-rigid reinforcing ribs after being formed, so that the false target has certain rigidity after being formed, and can resist external interference forces such as high-altitude thin atmospheric resistance, gravity gradient and the like; meanwhile, the false target is made of flexible and semi-rigid materials, so that the false target cannot generate fragments in space.
