- Base_bleed abstract "Base bleed is a system used on some artillery shells to increase their range, typically by about 30%.Most of the drag on an artillery shell comes from the nose of the shell, as it pushes the air out of its way at supersonic speeds. Shaping the shell properly can reduce this greatly. However, another powerful source of drag is the low-pressure area left behind the shell due to its blunt base. This drag is difficult to remove, because the shell must be \"nose heavy\" in order to have proper ballistics, and cannot easily be shaped into a more aerodynamic form.Base bleed can reduce this drag without extending the base of the shell. Instead, a small ring of metal extends just past the base, and the area in the rear of the shell is filled with a small gas generator. The gas generator provides little to no thrust, but simply increases the pressure in the area behind the shell with an inflow of gas, dramatically reducing the drag. The only disadvantages are a small loss of accuracy due to the somewhat more turbulent airflow, and a small loss in explosive payload due to some of the space inside the shell being taken up by this mechanism.Since base bleed extends the range by a percentage, it is only really useful on longer range artillery where some 5 km to 15 km increase can be achieved. Until the late 1980s the small gains in range was not considered worthwhile for field artillery. Base bleed shells are becoming more common in units equipped with modern artillery which have far greater range than the old.".
