Drag modeling.

pressure drag. The force on an object that resists its motion through a fluid is called drag. When the fluid is a gas like air, it is called aerodynamic drag or air resistance. When the fluid is a liquid like water it is called hydrodynamic drag, but never "water resistance". Fluids are characterized by their ability to flow.26 Sep 2018 ...

Custom Drag Models (CDM’s) for bullets are a more refined way of modeling drag for bullets because you’re not referencing a standard like G1 or G7, rather you’re using the actual measured drag of a specific bullet in a ballistic ...

Satellite Drag. Drag is a force exerted on an object moving through a fluid, and it is oriented in the direction of relative fluid flow. Drag acts opposite to the direction of motion and tends to slow an object. As an example, think of running against a high wind and feeling the drag pushing you back in the direction of relative fluid flow.Drag models are essential for estimating fluidization applications correctly. Various drag models were compared and validated against experimental data. The models show high dependency on the system where they were validated originally. Care must be used when choosing appropriate model.

The G7 drag model has proportionally more drag at transonic speed compared to the G1 drag curve, and by a significant margin. In fact, transonic speed is where drag models diverge the most. As a result of the divergence in drag models at transonic speed, ballistic solvers can calculate different transonic trajectories for G1 vs. G7 BC models.
