Problems solved by technology

In the above methods, the photos obtained by high-speed photography and slit photography are small and unclear, which makes it difficult to calculate the given quantity; the interpretation of the long and short axes of the hole with broken edges by the paper target method is not strict, so its test accuracy is poor
The optical vertical target method has poor test accuracy due to the imprecise judgment of the coordinate positions of the warhead and tail.
The above methods are external measurement methods, it is difficult to obtain the complete nutation parameters of the projectile flight process

Embodiment 1

[0058] Embodiment 1. The nutating parameter measurement method of projectile

[0059] The method for measuring the nutation parameters of the projectile in this case is a new method of measuring the nutation parameters of the projectile using the internal test method. The internal test method in this case is to install the test device inside the projectile, recover the test device after the live ammunition test, and read the test The data stored in the device can be analyzed and processed to obtain parameters such as the nutation period and nutation angle of the projectile during flight. The specific implementation process or steps of the nutation parameter measurement method of this example projectile are by Figure 1 to Figure 15 Joint indication or explanation. in figure 1 is the schematic diagram of projectile motion without nutation, figure 2 It is a schematic diagram of projectile motion with nutation, and the two diagrams clearly illustrate the situation of projecti...

Abstract

The invention discloses a measuring method of nutation parameters of a pill, and belongs to the technical field of electronic testing. The measuring method of the nutation parameters of the pill is an internal measuring method, wherein a testing device is installed inside the pill. The measuring method of the nutation parameters of the pill comprises the steps that (1) the testing device is placed into a body of the pill to be launched; (2) the testing device is used for measuring the nutation parameters in a flight process of the pill, and is used for storing the nutation parameters in the flight process of the pill; (3) the testing device which finishes testing is recovered, and recorded measured data are read into a computer; (4) the data input into the computer are processed, and a nutation period of the pill is calculated; and (5) a nutation angle of the pill is calculated according to the measured data. The measuring method of the nutation parameters of the pill overcomes shortcomings or defects of various external measuring methods which are used for measuring the nutation parameters of the pill, and is novel in technology. The fact that the measuring method of the nutation parameters of the pill is effective is confirmed through calculation on measured data of a caliber of ** of a pill and a caliber of ** of another pill. The measuring method of the nutation parameters of the pill has important practical significance and important theoretical significance on measurement on the nutation parameters of the pill is worth adoption and popularization.

Description

1. Technical field [0001] The method for measuring the nutation parameter of a projectile disclosed by the invention belongs to the technical field of electronic testing, and specifically relates to a new method for measuring the nutation parameter of a projectile by using the rotational speed information of the projectile by adopting an internal test method. 2. Background technology [0002] For rifled guns, while the high-speed rotating projectile is flying in the air, the projectile shaft makes some periodic swinging motion around the ballistic tangent, that is, nutation. Assuming that the center of mass of the projectile coincides with the origin of coordinates O, the N axis is the tangential direction of the ballistic --- the direction of the center of mass movement, and the Z' axis is the axial direction of the projectile. ′ axis coincidence, such as figure 1 As shown; when the projectile motion has nutation, the angle δ between the tangential N axis of the ballistic ...
