Abstract

The invention belongs to the laser application technology field, relates to a test system and method for the joint destruction effect of laser and the surface airflow and aims to solve disadvantages of high cost, the huge size and the narrow application scope existing in a test system in the prior art. The test system for the joint destruction effect of the laser and the surface airflow comprisesa target, a beam module, an airflow simulation module and a monitoring device, wherein the beam module comprises a laser device and a first total reflective mirror, the first total reflective mirror is arranged on an emission light path of the laser device, the airflow simulation module comprises a motor and a supporting assembly fixedly connected with a motor rotation shaft, the first total reflective mirror, the target and the monitoring device are fixed at an upper end of the supporting assembly, the first total reflective mirror is arranged in the middle, the target and the monitoring device are arranged at two sides of the first total reflective mirror, the light emitted by the laser device is reflected by the first total reflective mirror to irradiate onto the target, and a light signal on the surface of the target enters the monitoring device and is not blocked by the first total reflective mirror.

Description

technical field [0001] The invention belongs to the technical field of laser applications, and relates to a test system and method for the combined destruction effect of laser and surface airflow, in particular to a laser irradiation effect test system and method for simulating the flight state of a target by means of high-speed rotation. Background technique [0002] In the study of the effect of high-power laser damage to flying targets, it is necessary to simulate the flight state of the target in a laboratory environment. The usual practice is to use a wind tunnel to conduct simulation experiments to study the influence of surface airflow on the laser damage effect of the target. In the Chinese patent with the publication number CN105973563A "A Test System and Method for Combined Destruction Effect of Intense Laser and Supersonic Wind Tunnel", a method for studying the effect of laser irradiation by using a wind tunnel to simulate the airflow on the surface of the target...
