This is a model of the Turboprop Engine for Business Aircraft, etc. Engine of this class has many features other than the large size jet (fan) engine. - Smaller size - Higher RPM - Lighter weight These features make the complex air flow and unique configuration. There are two types of this class engine; - Direct drive This type model was uploaded to the following URL. https://cults3d.com/en/3d-model/tool/turboprop-engine-for-business-aircraft-cutaway - Free turbine This cutaway model is the free turbine type.
