 * The Swedish Marine, not by Dr. Bull, largely pioneered the field. The first patent for the existing type of Base-bleed is a Swedish patent from the 60th, which was sold to PRB in Belgium and then some rights for the ERFB-projectile was sold to SRC (Dr. Bulls company). The Swedish Coastal Artillery was the first to use it on 75 and 120 mm artillery.

The shell does not need to be "nose heavy", since it is spin stabilized.

It's an odd statement, significant rear taper tends to make a projectile more stable! The reasons such shapes are avoided is because they offer a modest advantage while entailing significant packaging & manufacturing difficulties and greater barrel wear.

Base bleed, increases range, by reducing turbulence (ML).

Surely reducing the vacuum behind the projectile will reduce the turbulence caused as the surrounding airflow attempts to fill the void. Why, then would this lead to instability and loss of accuracy? (NSA)

The increased base pressure acting behind the centre of mass reduces stability. Pushing is unstable (ML).

How does the gas generator work?

It burns, producing a low pressure (several psig) gas. It must be tough enough to withstand firing. Tire rubber (polybutadiene) impregnated with a powerful oxidizer such as ammonium perchlorate, would be suitable. —Preceding unsigned comment added by 65.92.120.254 (talk) 18:05, 11 November 2007 (UTC)

I just removed the external link to nasa -- it's nowhere near related to this article. ... aa:talk 01:43, 27 June 2008 (UTC)
