Summary

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).
