A gas sampling apparatus having a sampling film in a cartridge includes the cartridge configured to store and send the sampling film out, and the sampling film detachable from the cartridge, wherein the sampling film is configured to adsorb a target material and prevent disturbance between sampled target materials.

Apparatus for sampling gas, drone therewith and control method thereof

A rotor, a turbine, and a gas turbine including the same are provided. The rotor includes a pair of disks rotating about an imaginary central axis and arranged parallel to each other in an axial direction, a replaceable self-locking sealing assembly interposed between the pair of disks, and a fastening section disposed on the sealing assembly to fasten the sealing assembly to the disks. The disk includes a sealing slot disposed on an opposite surface to another adjacent disk and a head slot disposed outward from the sealing slot with respect to a radial direction of the to disk. The sealing assembly includes a main body with one end inserted into the sealing slot through the head slot from an outside of the disk and a sealing head disposed on another end of the main body to be seated on an inner wall of the head slot to restrict the main body from being moved.

An apparatus for producing an infrared spectrum according to one example of the present disclosure includes: a toxic chemical gas and background infrared spectrum acquisition portion of acquiring a background of a target area and an infrared spectroscopic signal of a gas contaminant plume existing in the background; and a toxic chemical gas infrared spectrum generation portion of training a Generative Adversarial Network (GAN) using acquired background radiation intensity data as learning data, and automatically generating a toxic chemical gas simulation infrared spectrum signal according to an environment setting inputted from a user using a learned GAN. According to the present disclosure, there is an effect that an infrared spectrum of atmosphere contaminated by a toxic chemical gas may be acquired without outdoor experiments using a real toxic chemical gas.

Method and apparatus for producing infrared spectrum

The present invention relates to a gas turbine which includes a cooling system provided with cooling air supply paths bypassed through an outside casing and, more specifically, to a gas turbine including a cooling system and a cooling method, wherein, in order to supply cooling air to a plurality of turbine blades and other devices provided to the inside of the gas turbine, cooling air supply paths are not provided to the rotor center shaft of the gas turbine but provided around the outer casing of the gas turbine so as to achieve the increased effect in the aerodynamic efficiency of the compressor and the turbine. According to the above structure and method, it may be possible to provide the cooling air supply paths not to the rotor center shaft of the gas turbine but around the outer casing of the gas turbine, thereby finally achieving the increased effect in the aerodynamic efficiency of the compressor and the turbine.
