The ERA project was created in 2009 as part of NASAs Aeronautics Research Mission Directorates (ARMD) Integrated Systems Aviation Program (IASP). The purpose of the ERA project was to explore and document the feasibility, benefit, and technical risk of vehicles concepts and enabling technologies to reduce aviations impact on the environment. The metrics for this technology is given in Figure 1 with the N+2 metrics highlighted in green. It is anticipated that the United States air transportation system will continue to expand significantly over the next few decades thus adversely impacting the environment unless new technology is incorporated to simultaneously reduce nitrous oxides (NOx), noise and fuel consumption. In order to achieve the overall goals and meet the technology insertion challenges, these goals were divided into technical challenges that were to be achieved during the execution of the ERA project. Technical challenges were accomplished through test campaigns conducted by Integrated Technology Demonstration (ITDs). ERAs technical performance period ended in 2015. |
