Aero-engine intake aerodynamic design and analysis

Lead Research Organisation: CRANFIELD UNIVERSITY
Department Name: Sch of Aerospace, Transport & Manufact

Abstract

Previous work at Cranfield University has developed methods for the design of intake aero-lines for podded engine configurations. These tools are being extended to three-dimensional configurations with the ultimate aim of developing a viable short intake for future ultra-high bypass ratio configurations. This related research encompasses the development of optimization methods as well as including the interaction between the fan and the intake using low-order fan models.The overall aim of the PhD research is to develop tools and design guidance in the design of short intakes in association with fan systems for future ultrahigh bypass engine configurations.

Description The need to reduce specific fuel consumption in commercial aircraft engines has led to configurations with a high bypass ratio and lower fan pressure ratio. However, this consequently leads to larger fan diameters and an increase in weight and drag due to larger nacelles. Shorter intakes are needed to partially counteract these two drawbacks. The reduced internal diffusion capability for the ingested flow and strong aerodynamic coupling with the fan make short intake design challenging.
This project aims to develop an industrially viable design approach for aero-engine short intake and to quantify the boundaries of the viable design space. An improved understanding of the aerodynamic mechanism involved in short intake distortions will be established and primary relationships between fan and intake design identified.
A robust methodology for short intake analysis has been proposed and the impact of different modelling strategies on the intake design boundaries has been established.
Exploitation Route Design guidance in the design of short intakes in association with fan systems for future ultra-high bypass engine configurations will be developed. Aero-engine short intake design guidance can be used within an industrial contest during the early design process for a rapid determination of the initial design parameters.
