THE TECHNOLOGY:
Innovators at the NASA Langley Research Center have developed a system for predicting sonic boom propagation of supersonic aircraft, the sBOOMTraj tool. This software system enables efficient computation and mitigation of sonic boom loudness across the entire duration of a flight mission. The primary challenge with supersonic flight remains the mitigation of the sonic boom to levels that will be acceptable to humans on the ground. As industry progresses towards realizing a commercial supersonic aircraft, the push from regulators to reduce noise levels has intensified. To meet this need, sBOOMTraj was developed to predict and mitigate sonic boom levels without resorting to less accurate shock theory or other numerical post-processing techniques. The software incorporates atmospheric and terrestrial effects, as well as functionality to handle aircraft trajectories and maneuvers. SBOOMTraj has potential applications in the design and development of next generation supersonic aircraft, and may also enable pilots and operators of such aircraft to plan flight paths to reduce their noise footprints.
The sBOOMTraj tool offers an updated approach to accurately predict sonic boom ground signatures for supersonic aircraft. The tool is based on the numeric solution of the augmented Burgers equation where the regular Burgers equation is augmented with absorption, molecular relaxation, atmospheric stratification, and ray tube spreading terms in addition to the non-linear term from the regular equation. The primary idea behind such augmenting is that atmospheric losses are captured, which re... - Documents :
