Model based enterprise (MBE) in prototype compressor project for new turboprop engine

Abstract

Model Base Enterprise (MBE) is the next generation strategy of product definition for comprehensive use during the whole product life cycle. Selected elements of the MBE concept were implemented during a new turboprop compressor development project. The goal of the project is to design, build and validate thru development testing the new compressor system maintaining shorter than typical overall development cycle of 4 years. Classical product definition methods based on typical 3D models and 2D drawings were not sufficient to meet project expectations – including increased compressor performance requirements, technical complexity, demanding schedule and ability to timely react to evolving project requirements. MBE strategy appeared to be the appropriate solution. Despite the concept has been successfully functioning for some time, the prototype compressor project implemented it in a wider scope than similar projects in the past. Model Based Enterprise includes: • Development phase: Model Based Definition (MBD), Engineering Design Control Structure (EDCS), Digital Engine (DE), 3D Stack-up analysis • Manufacturing phase: Computer Numerical Control (CNC), CAD2CAM review, In-Process Models (IPM) • Quality control: Coordinate-Measuring Machine (CMM) or CT Scanning The paper provides overview of MBE tools implemented in the Prototype Compressor project, discusses benefits and implementation obstacles.
