METHOD FOR VENTILATION AND REMOVAL OF POWDER GASES OF AN INHABITED COMPARTMENT OF AN ARMOURED VEHICLE Russian patent published in 2021 - IPC F41H7/03 B60H1/26 

FIELD: vehicles.

SUBSTANCE: invention relates to special vehicles with an armoured habitable volume (cabin, control module, functional module, etc.) and ports for firing small arms. The method for ventilation and removal of powder gases of an inhabited compartment of an armoured vehicle includes creation of air overpressure by a filter and ventilation system and removal of air containing carbon monoxide from the inhabited compartments. Forced removal of powder gases is executed by means of exhaust ventilation apparatuses located directly above the ports for firing small arms, and the external armoured flap (2) thereof controlled remotely by means of an electromagnet (4) with a servo drive (3) and equipped with a rubber seal (5) protects from the damaging factors of small arms and provides a tight fit thereof to the body in the closed state.

EFFECT: ventilation and removal of powder gases during firing from an inhabited compartment of an armoured vehicle directly at the firing sites, general reduction in the level of the maximum acceptable concentration of powder gases with ensured protection from the damaging factors of small arms.
