A pneumatic starter system for a turbine engine. The pneumatic starter system includes a pneumatic starter and a compressed gas storage unit. The pneumatic starter is configured to cause at least one turbine of the turbine engine to rotate. The compressed gas storage unit is configured to store oxygen rich gas and expel the oxygen rich gas to power the pneumatic starting system to cause the at least one turbine to rotate. The pneumatic starter system also includes a first exhaust path configured to direct at least a first portion of the oxygen rich gas exhausted from the pneumatic starter to a turbine combustion zone of the turbine engine to create an oxygen rich fuel mixture.
