Sub-Project 1 for whole engine assessment

SP1 oversees the technical unity of the other sub-projects, and is in charge of design for each of the three engine architectures.

Objectives

The whole engine assessment manages the integration of concepts and breakthroughs developed in others subprojects by defining for each requirements. It means that the VITAL project is a projective engine integration in order to :
• To provide requirements and objectives for technologies
• To assess propulsion concepts
• To establish ability to meet ACARE goals
• To provide the ability to compare the environmental and economic impact of potential engines

Challenge



State of the art
• Optimisers have been used on engines to minimise maintenance costs
• Impact of engine technology changes on global climate change

Breakthrough
• Pulling these and many more models together into one optimisation programme that can assess the impact of technologies in various economic and environmental scenarios.

Approach


• Define requirements for other SPs of VITAL
• Assess the impacts of the results predicted
by each SP
• Assess the impacts of the results achieved
by each SP
• Create an optimiser based on clear understanding of the technology
and how to scale it

Expected results


• Requirements for the engine modules that in combination can meet the ACARE goals
• An optimisation process for minimising the economic and environmental impacts of various engines
• Optimised engine designs

Sub-Project 2 for Fan modules
SP2 tests new fan module concepts and measures their aero-acoustic performance (contra-fan or lightweight fan).
Sub-Project 3 for Booster
SP3 evaluates the slow and high-speed booster (low-pressure compressors) concepts applicable to the different configurations.
Sub-Project 4 for Structures
SP4 focuses on new lightweight structural material (Hot and cold structures form the engine " back bone"). They provide basic engine stiffness and transfer high mechanical loads to and from the engine interior. Therefore the structures contributes to 15 - 20% of the engine weight.
Sub-Project 5 for Low pressure shaft
SP5 tests new concepts for a low-pressure shaft (which has to handle higher torque loads because of the slower fan speed). (Source : Brochure)
Sub-Project 6 for Low pressure turbine
SP6 seeks to identify new, lighter and quieter turbine concepts.
Sub-Project 7 for Installation
SP7 evaluates the impact of installing a high-bypass-ratio engine under the wing.
