Abstract

MIT, Aurora Flight Sciences and Pratt & Whitney are an industry-university team that has worked on a NASA sponsored project entitled “Aircraft and Technology Concepts for an N+3 Subsonic Transport“. The aim was the identification of advanced airframe, propulsion concepts, and enabling technologies for commercial aircraft for entry into service in 2030-2035 that provide a reduction of 71 EPNdB in noise below Stage 4, better than 75% LTO NOx emissions below CAEP 6, better than 70% reduction in fuel burn relative to a baseline aircraft and that exploits metroplex concepts. The team defined the scenario and aircraft requirements; developed two conceptual aircraft designs with step changes in terms of fuel burn, emissions (noise and LTO NOx), and climate impact; identified the technology enablers; developed first-principles methodology to simultaneously optimize the airframe, engine, and operations parameters; and generated risk assessment and technology maturation plans for configurations and enabling technologies. The presentation is an overview of this work

Biography

Dr. De la Rosa Blanco is a Research Engineer at the Department of Aeronautics and Astronautics where she has been working on the Phase I of a NASA sponsored program led by MIT entitled “Aircraft and Technology Concepts for an N+3 Subsonic Transport“. She has experience in the areas of turbomachinery, noise, instrumentation, and airframe-engine integration. Prior to MIT, she was a Senior Engineer at Aerodyne Research Inc., where she was involved in the analysis of field measurements of gas phase and particulate emissions of jet engines and the development of an aerodynamically quenching gas sampling probe. Previously, she was a postdoctoral researcher at Cambridge University (UK) working on the engine design for the Silent Aircraft Initiative. She also conducted a research project with Rolls Royce (UK) and Industria de Turbo Propulsores (Spain) to assess the effect of endwall contouring on Low Pressure Turbines (LPT). She obtained her PhD from the Whittle Laboratory at Cambridge University (UK) on the field of secondary flows in LPT. Previously, she worked on LPT aerodynamic design at Industria de Turbo Propulsores in Madrid (Spain). She received her B.S from Escuela Técnica Superior de Ingenieros Aeronáticos in Madrid (Spain).
