| 31. | The 7N21 ( 9?9mm overpressure variant features an armour-piercing bullet and generates a peak pressure of.
|
| 32. | However, the deflection of propellant gases rearward and the resulting overpressure may cause whiplash to the crew.
|
| 33. | So it could be that this opening is specific to the fan drive segment creating the large overpressure.
|
| 34. | This mine is resistant to traditional explosive mine countermeasures, which use sudden blast overpressure to detonate mines.
|
| 35. | Inert gas lines are usually vented out of a gas bubbler placed in-line to prevent overpressure.
|
| 36. | Metallurgic examination of the tube fragments determined that cumulative damage may have occurred from overpressures of earlier rounds.
|
| 37. | Still it is possible for overpressures to occur when the washing machine or dishwasher suddenly closes a supply valve.
|
| 38. | Later test explosions of nuclear weapons with houses and other test structures nearby confirmed the 5 psi overpressure threshold.
|
| 39. | Similarly grassy fields and lots of foliage can help attenuate the strength of the overpressure of a sonic boom.
|
| 40. | The enclosed hull reduced situational awareness but allowed for the installation of central heating and an NBC overpressure system.
