About this 3D model

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 configuration. There are two types of this class engine; - Direct drive This cutaway model is the direct drive type. - Free turbine Features of this model are; ①. Integral-type Reduction Gear Box with an Air Intake ②. High Ratio Reduction Gears (including Planetary) ③. 2 stages Centrifugal Compressor (Impeller) ④. Reverse Flow Combustion Chamber ⑤. Axial stage Turbine ⑥. For the bearings (BRG), the printable dummy BRG are prepared to reduce cost instead of the metal ball bearing.
