The objective of the framework contract is to improve the ICAO Annex 16 Volume II engine emissions sampling and measurement requirements for nvPM mass and number and to propose more robust practices. The work aims at:
- analysing the relative share of aircraft fitted with engines not regulated for nvPM in operations and emissions at individual European airports;
- proposing and testing new or novel sampling designs and measurement techniques taking into account the state of the art;
- measuring gaseous emissions (e.g. NOx, HC, CO, CO2), smoke emissions, nvPM mass and number emissions, nvPM particle size for both regulated and non-regulated engines (e.g. small turbofan engines with a rated thrust below 26.7 kN, turboprop, turboshaft).
As outcome of this research and test programme, the contractor shall recommend modifications or new add-ons to the existing standards. The proposed changes shall be backed by an appropriate scientific and technical rationale that substantiates their underlying scientific reasoning and their practicability for field deployment.
The outcome will support the work carried out within ICAO Committee on Aviation Environmental Protection (CAEP) and the Society of Aerospace Engineers International (SAE) Committee E-31 (Aircraft Engine Gas and Particulate Emissions Measurement Committee).
The main tasks and deliverables
Within this framework contract, the following tasks are planned:
- Review of the state of the art relating to the aviation environmental policy assessment;
- Review of the contents, chosen approaches and compromises made;
- Elaboration of proposals for improved and novel nvPM measuring concepts;
- Impact assessment of nvPM emissions from non-regulated engines and selection of engines for emission measurements;
- Planning and performance of the non-regulated engine emissions tests;
- Development of proposals for a more accurate correlation between SN and nvPM mass, and between nvPM mass and number;
- Development of recommendations on updates to the certification of fuel specifications.
