Theoretical study on performance optimization of a turbocharged diesel aircraft engine is presented in this article. It is based on a verified engine thermodynamics and fluid dynamics simulation model. An efficient air management strategy for increasing power-to-engine displacement ratios of a turbocharged diesel aircraft engines is introduced and analysed. Air management strategies generally applied to turbocharged spark ignition aircraft engines do not enable to take full advantage of potentials given by turbocharging diesel aircraft engines. A conceptually different air management strategy, where turbocharger's waste-gate is fully closed up to the critical altitude, was therefore proposed and investigated in this article. Proposed air management strategy assures increased safety of engine operation through very simple and reliable engine controlling. Guidelines for selecting adequate air management components are also given in this article.
