Update on Prediction Uncertainty Reduction (PUR) Tech Challenge

Abstract

NASA has taken on a Technical Challenge to reduce the uncertainty in prediction of noise from near-term commercial supersonic aircraft. To date, an assessment has been done to baseline this effort, quantifying how much more uncertainty exists when the system-level prediction methods are applied to supersonic aircraft as compared to conventional aircraft. And an assessment has been made for the uncertainty in the physics-based simulations for jets. These will be briefly demonstrated.

Detect-and-Avoid in Off-Nominal Situations for Supersonic Transport Aircraft in Upper Class E Airspace

This thesis researches potential failure conditions within supersonic and potential hypersonic aircraft. The most critical off-nominal situations have been identified to be Engine Failures, Rapid Decompression and High Altitude Radiation. Having in mind, current regulatory requirements as well as past operations of Concorde, potential locations for different speeds have been modeled to identify safe operational volumes. With an emphasis on the engine failure case as part of the thesis requirement, a potential first order approach to future DAA systems is described in order to add these models on top of current conflict resolution models.

Aeroacoustic Validation of Installed Low Noise Propulsion for NASA's N+2 Supersonic Airliner

An aeroacoustic test was conducted at NASA Glenn Research Center on an integrated propulsion system designed to meet noise regulations of ICAO Chapter 4 with 10EPNdB cumulative margin. The test had two objectives: to demonstrate that the aircraft design did meet the noise goal, and to validate the acoustic design tools used in the design. Variations in the propulsion system design and its installation were tested and the results compared against predictions. Far-field arrays of microphones measured the acoustic spectral directivity, which was transformed to full scale as noise certification levels. Phased array measurements confirmed that the shielding of the installation model adequately simulated the full aircraft and provided data for validating RANS-based noise prediction tools. Particle image velocimetry confirmed that the flow field around the nozzle on the jet rig mimicked that of the full aircraft and produced flow data to validate the RANS solutions used in the noise predictions. The far-field acoustic measurements confirmed the empirical predictions for the noise. Results provided here detail the steps taken to ensure accuracy of the measurements and give insights into the physics of exhaust noise from installed propulsion systems in future supersonic vehicles.

NASA's Pursuit of Low-Noise Propulsion for Low-Boom Commercial Supersonic Vehicles

Since 2006, when the Fundamental Aeronautics Program was instituted within NASA's Aeronautics Mission Directorate, there has been a Project looking at the technical barriers to commercial supersonic flight. Among the barriers is the noise produced by aircraft during landing and takeoff. Over the years that followed, research was carried out at NASA aeronautics research centers, often in collaboration with academia and industry, addressing the problem. In 2013, a high-level milestone was established, described as a Technical Challenge, with the objective of demonstrating the feasibility of a low-boom supersonic airliner that could meet current airport noise regulations. The Technical Challenge was formally called "Low Noise Propulsion for Low Boom Aircraft", and was completed in late 2016. This paper reports the technical findings from this Technical Challenge, reaching back almost 10 years to review the technologies and tools that were developed along the way. It also discusses the final aircraft configuration and propulsion systems required for a supersonic civilian aircraft to meet noise regulations using the technologies available today. Finally, the paper documents the model-scale tests that validated the acoustic performance of the study aircraft.
