Technical Field

The invention belongs to the field of signal detection, and particularly relates to a missile-borne storage testing device and method based on hole-seam coupling.

Background

A large number of tests are required to be completed in the research and development processes of shells, rocket projectiles, missiles, rocket sleds and the like to verify whether various performances meet design indexes. From the initial sample development of the projectile body to the batch production when stereotypeing, all need carry out a large amount of pilot experiments in each stage and detect the projectile body in the performance of transmission and flight in-process, discover the problem that the projectile body probably appears when design and production, improve constantly, let novel projectile body exert best effect on the battlefield.

The missile-borne storage testing device is mainly used for collecting and storing various parameters during a missile flight test, and the frequently collected missile parameters comprise chamber pressure, flight path acceleration (overload), flight time, temperature in a chamber and the like during launching. The designer can master the working state information of the projectile body in the test process through the collected data, finally, whether each parameter index meets the design requirement is evaluated, and then corresponding improvement is made, so that important experimental basis is provided for theoretical analysis and parameter setting of subsequent projectile body improvement.

The target range of the trial-shooting experiment of the novel launching weapon is mainly established in deserts without human smoke, grasslands, mountains and other places, the launching projectile is fast in flight, the distance is far away, the falling point range is large, then the testing device has to be added with a positioning module to carry out accurate positioning so as to conveniently recover the projectile, because the projectile-borne storage testing device is installed inside the projectile body, the metal shell can generate great shielding effect on satellite signals and wireless signals, the shielding prevention method commonly used at present is to arrange the storage testing device and an ejection device in a cavity of the experimental projectile, when the trial-shooting experiment is carried out, the storage testing device is ejected by the ejection device when the projectile body falls to a distance of thousands of meters from the ground, and the projectile body is safely landed by a speed reducer (such as a small parachute) after being separated from the projectile body. Because the storage testing device is ejected out of the metal elastic body, the antenna of the storage testing device is exposed outside, and positioning and communication are feasible. However, this method also has a number of disadvantages: 1. a complex ejection device needs to be installed inside the projectile body with limited space originally, so that the quality of the test projectile is greatly improved; 2. non-full trajectory testing, which does not meet the test requirements of many missile production trials; 3. additional protection measures are required to ensure the safety of storing the test device after ejection.
