Background Technology

[0002] Recently, the development of laser weapons has been actively underway. Laser weapons are a type of directed energy weapon that destroys or neutralizes targets by focusing high-output lasers directly onto them. Because laser weapons use directed energy, even objects moving at very high speeds can become targets. Additionally, they offer excellent precision and are inexpensive to fire per shot.

[0003] The development of laser weapons requires testing under various combat scenarios. However, there are physical limitations to directly simulating diverse combat situations. In particular, when developing laser weapons that target flying objects, it is practically difficult to conduct experiments in which a target is launched, irradiated with a laser, and its state measured by the laser.

[0004] The aforementioned background technology is technical information that the inventor possessed for the derivation of the present invention or acquired during the process of deriving the present invention, and it cannot be considered as publicly known technology disclosed to the general public prior to the filing of the present invention. The problem to be solved

[0005] The present invention aims to solve the aforementioned problems by providing a laser engagement simulation device capable of simulating a high-speed flying target by spraying fluid onto the target and rotating the target, and measuring and analyzing the surrounding conditions of the target by irradiating a laser onto the flight-simulated target.

[0006] However, these problems are exemplary and the problems to be solved by the present invention are not limited thereto. Problems not mentioned will be clearly understood by those skilled in the art from this specification and the accompanying drawings. means of solving the problem

[0007] One embodiment of the present invention discloses a laser engagement simulation device comprising: a target rotation unit for fixing and rotating a target; a fluid injection unit for spraying a fluid onto the target to simulate the flight situation of the target; a laser emission unit for irradiating a laser onto the target; and a measurement control unit for measuring the temperature or pressure of the fluid sprayed from the fluid injection unit and measuring the temperature or pressure of the surface of the target or the surroundings of the target to collect and store data.

[0008] In this embodiment, the target may include a flying warhead.

[0009] In this embodiment, the target rotation unit may include a power generation unit and a target support that supports and fixes the target to the power generation unit.

[0010] In the present embodiment, the fluid injection unit may include a compressor, a storage tank for storing fluid compressed by the compressor, a pressure regulating unit for regulating the pressure within the storage tank, an injection nozzle connected to the storage tank and positioned in front of the target fixed to the target rotating unit, and a nozzle moving unit for moving the position of the injection nozzle.

[0011] In the present embodiment, the injection nozzle may include at least one fluid inlet disposed on the side and fluid injection ports continuously disposed in the circumferential direction.

[0012] In this embodiment, the laser emitting part may include a fixed part having 6 degrees of freedom.

[0013] In this embodiment, the measurement control unit may include a first measuring unit that measures the state of the target irradiated with the laser, a data collecting unit that collects measurement data obtained from the first measuring unit, and a slip ring that electrically connects the first measuring unit and the data collecting unit.

[0014] Other aspects, features, and advantages other than those described above will become clear from the specific details, claims, and drawings for implementing the invention below. Effects of the invention

[0015] A laser engagement simulation device according to one embodiment of the present invention can save costs for simulating actual flight situations by simulating the high-speed flight of a target.
