Subproject 1: Whole Engine Integration

For all core concepts the requirements and objectives are defined, starting with whole engine performance cycle data. The programme compares, assess and ranks the benefits of the advanced concepts, ensuring consistency of the results and monitoring progress towards the ACARE technical and economic objectives.

The new engine designs will be assessed in typical aircraft applications as indicated in figure 1.

A significant work package within NEWAC will be to adapt and develop the software tool TERA (Technoeconomic and Environmental Risk Analysis), previously created in the VITAL programme, in order to compare the environmental and economic impacts of the new designs. Issues to be addressed include performance, weight, engine installation, NOX and CO2 emissions, noise, fuel costs, maintenance cost and aircraft flight path and altitude.

The socio-economic model will identify engines with minimum global warming potential and lowest cost of ownership as shown in figure 2.
