PCBoom 7 Technical Reference, 2nd Edition

PCBoom is a suite of sonic boom propagation programs that applies full three-dimensional ray tracing based on geometrical acoustics. It predicts sonic boom ground waveforms and footprints from supersonic flight vehicles performing arbitrary maneuvers using a variety of built-in or user-supplied nearfield vehicle source definitions. It also computes loudness metrics, ground signature locations, and sonic boom propagation times. The nomenclature "PC" in PCBoom denotes that the programs were historically targeted to run on a personal computer.

PCBoom provides a valuable contribution toward sonic boom research as illustrated by the following examples:

• PCBoom allows for quick “what if” type predictions for a multitude of sonic boom scenarios, including low boom design iteration work.

• The detailed flight planning capabilities allow for flight conditions and waypoints to be provided to pilots to generate booms needed for research.

• PCBoom allows for post-flight analysis of as-flown trajectories with measured weather data.

• PCBoom has been used in sonic boom damage claim cases to determine claim veracity.
