Abstract
The invention in various embodiments is directed to systems and methods for mitigating damage from a shock wave using a gas having a specific impedance less than air.
Claims10
A method of mitigating damage from an explosion comprising,
- detecting an explosion external to a substantially contained environment,
- in response to detecting the explosion, substantially filling the environment with a gas having a specific impedance less than about 350 Pascal seconds/meter (Pa·s/m) to attenuate a peak overpressure within the environment resulting from a shock wave caused by the explosion, and
- venting the gas from the environment subsequent to the shock wave passing the environment.
A system for mitigating damage from an explosion comprising,
- a detector for detecting an explosion external to a substantially contained environment, and
- a supply of a gas having a specific impedance of less than about 350 Pa·s/m for substantially filling the environment in response to detecting the explosion to attenuate a peak overpressure within the substantially contained environment resulting from a shock wave caused by the explosion, and
- a vent for venting the gas from the substantially contained environment.
