Boosting Your Knowledge of Turbocharging (Part 1 of a 2 part series)

Boosting Your Knowledge of Turbocharging (Part 1 of a 2 part Series) By Randy Knuteson July 1999 A short 15 years after Orville and Wilbur made their historic flight at Kitty Hawk, General Electric entered the annals of aviation...

A preventative maintenance procedure that should be practiced universally is to allow the engine to sufficiently warm up before applying full power, and to avoid pulling power abruptly. It's also advisable to allow the engine to idle an additional three to five minutes prior to shutting it down. This allows the turbo to cool down and equalize temperatures before going to idle cut-off. These simple measures will reduce the possibility of oil residue coking in the hot turbine housing and should prolong the life of the turbo.

It's only as you consider the operational demands and the exacting details that factor into the analytical performance predictions in designing these systems that you gain a true appreciation for aircraft turbocharging.

Stay tuned. Part 2 in this two-part series will deal with the turbocharger control systems (valves and controllers) - both manual and automatic.
