This graph image could be recreated using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file "AircraftCompressorDischargeTemperatureVSAltitude.svg" - then the template Vector version available (or Vva) does not need the new image name parameter.

Summary[edit]

Description
English: This graph compares the compressor discharge temperature on a supercharged aircraft engine as a function of altitude. Ambient atmospheric temperature and pressure are calculated using standard atmospheric models. The red line assumes the supercharger is putting out constant boost of 10.2 psia (0.70 bar), sufficient boost to make up for the atmospheric pressure at 10,000m (32,800ft) altitude. The blue dotted line assumes a constantly varying boost to maintain the engine's manifold pressure at 1 atm (14.696 psia). It can be seen that constantly varying the boost significantly reduces the CDT of the supercharger (although it also results in lower power output).
