Aerodynamic Trajectory Engine

This engine incorporates Reynolds-number drag coefficients ($C_d \approx 0.32$), spin-decay Magnus vertical lift ($C_l$), and ambient air density corrections. Coors Field accounts for 18% thinner barometric air density at 5,280 ft.

Ballpark Fence Profiles

Camden Yards features the moved-back left field wall (398 ft power alley, 13 ft height). Fenway Park features the 37-ft Green Monster in LF at 310–315 ft, while Yankee Stadium provides the famous 314-ft short porch in RF.
