AGENDA

The CoDI (Consortium for Digital Interface) Propulsion Interface GRA (iGRA) is a skeleton of common engine-to-air vehicle interfaces. The iGRA is deploying as the Propulsion Acquisition standard governance for how to interface between engine and air vehicles, converting the traditional Interface Control Document (ICD) into an authoritative, SysML-compliant Interface Control Model (ICM). The iGRA training session will cover what the iGRA is, how it came to be, and provide an example of how to utilize the model to deploy an ICM.

This tutorial will employ a small turbojet to demonstrate development of models for complete analysis of an engine. The focus will be on creation of models that enhance understanding of the engine operation, models applicable to engine redesign and derivative designs, and analyses in support of validation of computational tools.

Modern military aircraft electrical demands present a complex challenge to electrical power generation on the vehicle. This session explores how the magnitude and dynamic characteristics of the vehicle's electrical power system necessitate leap-ahead choices in electric generator technology, integration, and testing. Challenges associated with dynamic and negative-impedance electrical loads, engine/generator pairing and integration, practical generator SWAP, maintaining overall system protection and reliability, and ensuring electrical power quality/stability will be discussed.
