Description
Technical Field
The utility model belongs to the technical field of the mechanical force detects, in particular to novel fire ware locking force detects device.
Background
The launcher is hung on a universal weapon hanger below a helicopter short wing, can safely and reliably carry a plurality of aviation rocket projectiles through the launching tube, realizes the transmission of an ignition signal and an opening time signal according to a fire control system instruction, gives the rocket projectiles initial shooting and muzzle speed, and realizes single-shot and continuous-shot launching at a certain launching interval and a certain launching sequence. After the rocket projectile is ignited in the rocket launcher, only when the gas thrust of the engine reaches a certain value, the rocket projectile can break loose from the locking of the conductive locking component at the tail part of the launching tube of the rocket launcher and fly forwards, and the resistance of the conductive locking component on the rocket projectile from rest to movement is the locking force. The locking force is a value interval and is not a fixed value. Too little latching force may cause "blow out" and too much latching force may cause "finish blasting".
Even when the locking force is within a specified allowable range, the initial disturbance and the flight starting force caused by the inconsistency of the locking forces of the plurality of launch tubes have a large influence on the shooting accuracy. Assuming that the locking force of each launch tube is between a specified maximum and minimum (the range difference is up to several hundred N), the initial force and initial flight conditions achieved by the projectile are not consistent due to the inconsistent locking forces of the plurality of launch tubes, and the projectile may fly out of normal trajectory with greater projectile spread. The reasons are two: one is the increased projectile spread due to initial disturbances caused by uneven latching forces. Factors influencing the shooting accuracy of the rocket projectile are many, such as initial shooting calculated by a fire control system, initial disturbance of the rocket projectile, uneven burning of gunpowder, inconsistent center of mass of the projectile body, high-altitude wind and the like. The initial disturbance refers to random vibration generated by the external influences of gas flow, forward firing on follow-up firing, locking force and the like on the launching tube during launching, and the locking force is a sudden load for the igniter, is a main part of external force for generating random vibration and is also an important factor for causing dispersion. When multiple tubes are fired simultaneously, the reaction force borne by the launching tube with the maximum locking force is the largest, the vibration of the igniter is the largest, and the initial disturbance is the largest; the launch tube with the lowest latching force experiences the least reaction force, the minimum shock to the initiator and the minimum initial disturbance. The effect of the two extreme latching forces necessarily results in a change in the initial launch of the projectile and an increase in the spread of the projectile. Second, projectile dispersion is increased due to inconsistent initial velocity of the projectile caused by the latching force. When the locking force is close to the minimum value, the initial speed of the rocket projectile is reduced, the initial flight angle is reduced due to the influence of gravity at the moment of separating from the launching tube, and a near projectile is generated; the other possibility is that the rocket projectile is ignited and then rapidly discharged after overcoming the smaller locking force due to the small locking force, so that the consumption of gunpowder for overcoming the locking force is less, the subsequent acceleration time is prolonged, and the long projectile is generated; when the locking force is close to the maximum value, the initial speed of the rocket projectile is increased, the initial flight angle is increased, and a long projectile is generated; there is also a possibility that the rocket projectile needs to overcome a larger locking force after ignition to slowly discharge, so that the gunpowder is consumed to overcome the locking force, the subsequent acceleration time is short, and the near projectile is generated. These two extremes necessarily result in a large spread of projectiles.
To minimize the effects of initial disturbances and initial velocity inconsistencies, to maximize the uniformity of latching forces, and to minimize projectile spread, the conductive latch assembly latching force uniformity needs to be detected and adjusted. The existing special device for detecting the locking force of the igniter is lack, the locking force is inconsistent after the igniter is used for many times, the locking force condition of the igniter cannot be flexibly and simply obtained, and the problems of large projectile spreading surface, low shooting precision and the like are often caused.
