Abstract
Die Erfindung betrifft ein Verfahren zur Reduzierung des nach bestimmten Schußfolgen aufgrund unterschiedlicher Temperaturen zwischen der Rohrunterseite (9) und Rohroberseite (10) auftretenden Durchhanges eines Waffenrohres (1;11) sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for reducing after certain firing sequences due to different temperatures between the tube underside (9) and tube top (10) occurring sag of a gun barrel (1; 11) and a device for Execution of the procedure.
Um zu erreichen, daß auf einfache Weise der Durchhang eines Waffenrohres (1;11) gegenüber vergleichbaren bekannten Waffenrohren reduziert werden kann, schlägt die Erfindung vor, daß jeweils nach erfolgter Schußabgabe ein gasförmiges Medium vorgegebener Temperatur mit vorgegebenem Druck in das Waffenrohr (1;11) eingeleitet wird, derart, daß durch das definierte Durchströmen der Rohrbohrung (7') über einen vorgegebenen Zeitraum eine Konvektionsströmung verhindert wird und die bei bestimmter Schußfolge auftretenden Temperaturunterschiede zwischen der Rohrunterseite (9) und der Rohroberseite (10) weitestgehend verhindert werden. In order to achieve that the sag of a weapon barrel (1; 11) can be reduced in a simple manner compared to comparable known weapon barrels, the invention proposes that a gaseous medium of a predetermined temperature and pressure be introduced into the weapon barrel (1; 11 ) is initiated in such a way that a convection flow is prevented by the defined flow through the tube bore (7 ') over a predetermined period of time and the temperature differences occurring between the tube underside (9) and the tube top (10) during a certain firing sequence are largely prevented.
