NASA’s Environmentally Responsible Aviation (ERA) project began in 2009 to explore and document the feasibility, benefits, and technical risks of advanced vehicle concepts and enabling technologies for reducing aviation’s overall impact on the environment. Its goals included reducing community noise footprints, fuel burn, and nitrogen oxide emissions. This book reviews the advanced aircraft design concepts, construction technologies, and propulsion advancements that were researched by the ERA project.
