<p>The present invention relates to a method of increasing the range of air defence and artillery shells of the type which for reasons of firing technology have a rear surface which is at right angles to the shell axis, i.e. most conventional air defence and artillery shells. The invention also includes a design of air defence and artillery shells that corresponds with the said method. The invention is characterised by the rear surface of the shell which at the time of firing is at right angles to the shell axis being reformed to an aerodynamically more advantageous form (5, 9) when it has left the gun barrel and is on the way to the target.</p> |
