Work Plan Project h2020


will physically model, refine, explore and rank the preliminary concepts defined at the start of the project. The result will be a number of preferred ULTIMATE configurations. Additionally, common reference technology level assumptions for the year 2050 will be established.

will provide a multi-objective and multi-disciplinary evaluation platform for the assessment of technologies. Existing tools will be refined and adapted to the ULTIMATE challenges and new models will be developed. Engine and aircraft performance models for the year 2000 and year 2050 reference aircraft will also be developed.

The following key evaluation modules will be developed:

  • Engine performance: to predict mission fuel burn and provide input data for the aircraft performance, the engine general arrangement prediction, powerplant weight, noise and emissions prediction.
  • Engine general arrangement: to determine basic engine dimensions and the gas path layout including component stage numbers, interface definitions, component lengths, etc. This will require estimating technology parameters for aerodynamics, material definitions such as temperature capabilities and mechanical properties. This module will provide input to the engine weight module as well as the aircraft performance module.
  • Engine weight: to predict engine component and whole engine weight from engine basic dimensions as provided by the Engine general arrangement module and year 2050 materials capabilities. This module will provide input to the aircraft performance module.
  • Aircraft performance: to serve as a platform for the year 2050 long range intercontinental and the short range intra-European technology configurations, as well as the year 2000 reference configurations. The model will be set up for the assessment of aircraft-level improvements due to for instance advanced airframe aerodynamics and structures. This module will provide input to the operating cost module.
  • Noise: to estimate noise emissions (EPNLdB) at the ICAO certification points (take-off, approach, flyby and sideline) by the use of the component based noise source modelling. Based on modelling the Sound Pressure Levels (SPL) generated by the engine components and the aircraft, time-integrated Effective Perceived Noise Levels (EPNL) in static as well as in-flight conditions can be estimated. As part of the TERA 2050 analysis, the global engine noise is predicted in terms of EPNL for a given flight path. This module will provide input to the operating cost model.
  • Gaseous Emissions: to quantify on NOx emissions and to define a contrail prediction model allowing the assessment of the formation of persistent contrails. The gaseous emission models used will be based on either empirical/semi-empirical correlations, or will utilise 1D, physics based, stirred reactor combustor models as appropriate [Khandelwal, 2012]. This module will provide input to the operating cost model.
  • Operating cost: to assess direct operating costs for the ULTIMATE technologies as a function of fuel costs, time costs and environmental taxation costs. The influence of uncertainties in acquisition and maintenance cost will be addressed with the aid of sensitivity studies. Values of acquisition cost, maintenance cost and mission ranges for which the weighted average cost of capital (WACC) is greater than the internal rate of return (IRR) will be determined. These results will be used as the criteria to assess the economic viability of the ULTIMATE technologies.
  • Policy: to incorporate a “policy scenario evaluation” model which will be used to assess the potential of the technologies to cope with evolutions of regulations such as changes in fuel price and hypothetical environmental taxation scenarios (ranging from “business as usual” to “progressive environmental awareness” to “high environmental awareness”).
  • Optimizer: to allow design space exploration, parametric studies, sensitivity studies and trade-off studies as well as support for multidisciplinary and multi-objective analysis.

Will model  the propulsor technology advancements from the ULTIMATE project and will perform the propulsor and powerplant engine integration tasks.

will develop the preferred ULTIMATE core configurations to TRL2 and will optimize them to reach the SRIA 2050-targets. The results from WP4 individually, as well as from the advanced integration in WP3, will provide top-level module requirements and input to the technology roadmapping in WP5.

will anchor ULTIMATE in a continuously developing innovation framework to ensure that its results can be exploited by Europe´s aviation sector as soon as possible. This is done by communicating the ULTIMATE approach and results, by identifying technology gaps, developing roadmaps for each technology, extracting innovations and showing how the results will help to fulfill the SRIA 2050 targets.

will provide the collaborative framework and management infrastructure to monitor project progress and ensure the achievement of ULTIMATE results in the agreed schedule.
