FIELD: machine building. ^ SUBSTANCE: airport conditioner is made on single platform in form of closed body or container, in heat insulated walling of which there are made ports for intake of open and exhaust of used air. Inside the container there is arranged equipment for air pressurising, heating and cooling and special containers for installation of flexible connecting pipes. The special containers are made in form of noise dampers of round cross section inside of which there is positioned connecting pipe (9). On one end the pipe has flange (10) for connection to the system of air ducts of an aircraft, while another end the pipe has branch (11) ensuring smooth travel of pipe (9) along an internal channel of the noise damper and pressure tight packing of stretched pipe (9) between end surface of the noise damper and pipe (9). Outside the noise damper there are installed two coaxial cylinders (12, 13), the internal one of which is perforated; noise insulating material (14) is placed between the cylinders. ^ EFFECT: reduction of aerodynamic noise spread along channels and reduced dimensions of special containers for placement of connecting pipes and tools. ^ 2 dwg |
