WebA two-stage over/under airend design features first-stage compression on the top, interstage cooling between the compression chambers, and second-stage compression at the bottom. The over/under design utilizes “interstage” cooling via an injected “curtain” of lubricant/coolant, which improves overall efficiency. WebSome talking, some diagrams, and some real parts to help understand the recent turbine failure of a GE90-115B, and the FAA's emergency airworthiness directiv... WebWith two stage compressors, interstage cooling and the reduced internal losses due to a lower pressure across each stage increase the compression efficiency. Consequently, less energy is required to compress the air to the final pressure. Dry Type Rotary Screw. to easy in spanish
