NASA Wallops Flight Facility Site Wide Programmatic EIS, VA (Ongoing)
BRRC completed a noise study of various rocket systems at the NASA Wallops Flight Facility (WFF). This noise study examined four nominal launch vehicles representing the current baseline conditions, and potential operations, which include the largest orbital vehicles that would be launched from WFF. BRRC’s Launch Vehicle Acoustic Simulation Model (RUMBLE) was used to generate noise contours to assess the noise levels and exposures in the area surrounding WFF. Image Credit: NASA
BRRC’s Rocket Noise Model - RUMBLE
BRRC developed the high-fidelity launch vehicle simulation model, RUMBLE, to predict community noise exposure from spaceport launch, reentry, or static rocket operations. RUMBLE has been used in over fifteen rocket noise environmental studies, ten of which were performed as part of FAA commercial space licensing applications. FAA AEE has reviewed and accepted the RUMBLE noise modeling method for use in all ten of these commercial space studies.
Midland International Airport Launch Site Operator License EA, TX
BRRC performed a rocket noise and sonic boom impact study for the Midland International Airport to aid in their application for a Launch Site Operator License. BRRC developed noise contours using BRRC’s Launch Vehicle Acoustic Simulation Model (RUMBLE) to evaluate the noise impact from proposed operations of the Lynx, XCOR’s commercial reusable launch vehicle. In addition to noise, BRRC modeled the potential sonic booms generated by the launch and recovery portions of the Lynx space bound trajectory. Potential impacts were evaluated regarding human annoyance, hearing conservation, and the potential for structural damage. Image Credit: XCOR Aerospace
Energy-Based Acoustic Measurement System for Rocket Noise, UT
BRRC, in partnership with Brigham Young University, has developed advanced acoustic measurement, analysis, and modeling techniques for launch load predictions. Multiple full-scale static test fires have been performed at ATK Space Systems Test Services in Promontory, UT. This collected data was used to evaluate the measurement system and compare the performance of multiple probe prototype designs, evaluate historical rocket noise prediction methods, and to guide the development of future launch noise prediction models.
