Starting air data
Air consumption per start, incl. air for jet assist
1) LT cooling water flow first through LT stage charge air cooler, then
through lube oil cooler, water temperature outlet engine regulated by
mechanical thermostat
2) HT cooling water flow irst through water jacket and cylinder head, then
trough HT stage charge air cooler, water temperature outlet engine
regulated by mechanical thermostat
3) Tolerance: + 10% for rating coolers, - 15% for heat recovery
