Abstract
The invention provides a weapon simulator which comprises a combustion chamber having an exhaust port, a mechanism for admitting fuel gas to the combustion chamber, an ignition system for igniting fuel gas in the combustion chamber to cause an explosion, and an outlet valve to close the exhaust port. The outlet valve is arranged to open rapidly and with audible results in response to an explosive pressure rise within the combustion chamber. Further, the outlet valve comprises a collapsible diaphragm and a breechblock having opposing clamping parts releasable secured together and which releasably grip the collapsible diaphragm such that the gripped portion of the diaphragm is released on its collapse due to the explosive pressure rise in the combustion chamber.

A weapon simulator of the kind comprising a combustion chamber, means for admitting fuel gas to the combustion chamber, ignition means for igniting fuel gas in the combustion chamber to cause an explosion, an exhaust port in the combustion chamber and outlet valve means for closing the exhaust port and arranged to open rapidly and with audible results in response to explosive pressure rise within the combustion chamber, characterized in that the outlet valve means comprises a collapsible diaphragm and by a breechblock for releasably gripping the collapsible diaphragm such that the gripped portion of the diaphragm is released on its collapse due to the explosive pressure rise in the combustion chamber, the breechblock comprising opposed clamping parts which are releasably secured together.
A weapon simulator comprising:
- a combustion chamber having an exhaust port;
- means for admitting fuel gas to the combustion chamber;
- ignition means for igniting fuel gas in the combustion chamber to cause an explosion;
- an outlet valve to close the exhaust port, the outlet valve being arranged to open rapidly and with audible results in response to an explosive pressure rise within the combustion chamber, wherein the outlet valve comprises a collapsible diaphragm and a breechblock having opposing clamping parts releasable secured together and which releasably grip the collapsible diaphragm such that the gripped portion of the diaphragm is released on its collapse due to the explosive pressure rise in the combustion chamber.
