| 摘要 |
A simulated ammunition round (1) is characterised by a gunfire simulator (4) having a combustion chamber (28), means (21) for admitting fuel gas to the combustion chamber, ignition means (23) for igniting fuel gas in the combustion chamber to cause an explosion and an exhaust port (51) in the combustion chamber. The simulated ammunition round may comprise outlet valve means (14), e.g. a collapsible or frangible diaphragm, for closing the exhaust port and arranged to open rapidly and with audible results in response to explosive pressure rise within the combustion chamber. The simulated ammunition round may comprise means (38, 41) to enable firing of the round, the enabling means being responsive to loading of the round into the receiving chamber of a weapon.
