5 results about "Air cycle machine" patented technology

An air cycle machine (ACM) is the refrigeration unit of the environmental control system (ECS) used in pressurized gas turbine-powered aircraft. Normally an aircraft has two or three of these ACM. Each ACM and its components are often referred as an air conditioning pack. The air cycle cooling process uses air instead of a phase changing material such as Freon in the gas cycle. No condensation or evaporation of a refrigerant is involved, and the cooled air output from the process is used directly for cabin ventilation or for cooling electronic equipment.

Circular finned coalescer for aircraft environmental control systems

Aircraft air cycle machines include a first stage turbine, a second stage turbine that receives air from the first stage turbine, and a duct arranged between the first stage turbine and the second stage turbine. A circular finned coalescer is arranged within the duct and includes a central body, a first fin layer wrapped about the central body, a first parting sheet wrapped about the first fin layer, and a second fin layer wrapped about the first parting sheet. Each of the fin layers include a plurality of fin elements and channels are defined between circumferentially adjacent fin elements of each of the first and second fin layers. The channels are tortuous channels such that moisture carried on a flow through the channels will impinge upon surfaces of the fin elements and coalesce into water droplets.

Flexible interface coupling

An air cycle system for a gas turbine engine includes a heat exchanger having an air cycle inlet. An air cycle machine includes an air cycle machine outlet and an annular flexible interface coupling connecting the air cycle inlet to the outlet. The flexible interface coupling includes a receiving portion having a flared region across which a diameter of a heat exchanger portion increases and a landing portion across which the diameter of the heat exchanger portion is maintained. An air cycle machine portion is received in the receiving portion and includes an outlet flange and a diffuser radially inward of the outlet flange. The outlet flange includes a radially outward facing surface contacting a radially inward facing surface of the landing portion. The diffuser is configured to move axially and radially relative to the outlet flange.

Plate-fin coalescer for aircraft environmental control systems

PendingUS20260145795A1Gas treatmentAir-treatment apparatus arrangementsAir cycleAir cycle machine
Aircraft air cycle machines include a first stage turbine, a second stage turbine, and a duct arranged between the first stage turbine and the second stage turbine. A plate-fin coalescer is arranged along the duct. The plate-fin coalescer includes a housing, a first fin layer arranged within the housing, a second fin layer arranged within the housing, and a first parting sheet arranged between the first fin layer and the second fin layer. Each of the first fin layer and the second fin layer include a plurality of fin elements arranged in substantially parallel orientation relative an axis through the housing, and channels are defined between adjacent fin elements of the plurality of fin elements of each of the first fin layer and the second fin layer. Moisture carried on a flow through the channels will impinge upon surfaces of the fin elements and coalesce into water droplets for removal.

A novel temperature control device for salt spray testing

This utility model discloses a novel temperature control device for salt spray testing, relating to the technical field of salt spray testing equipment. It includes: a housing, a partition plate, a temperature and humidity regulating mechanism, and multiple radiant heating plates. The partition plate is disposed within the housing to divide it into a salt spray testing area and an equipment area. The temperature and humidity regulating mechanism includes an air circulation mechanism, a heater, and a humidifier. The air circulation mechanism is disposed in the equipment area, with both its inlet and outlet connected to the salt spray testing area to facilitate air exchange between the two areas. The heater is disposed in the equipment area to heat the air entering the area, and the humidifier is disposed in the equipment area to humidify the air entering the area. Each radiant heating plate is disposed in the salt spray testing area to maintain its temperature. This utility model effectively improves the temperature control response speed, enhances the accuracy of temperature control, and improves the efficiency and accuracy of salt spray testing.
