Abstract
An air intake for a motorized vehicle, for obtaining a low radar and IR signature of a ballistically protected air intake (10) of the vehicle. The air intake (10) has a perforated armour plate (12) lying level with an outer bodywork plate (14) of the vehicle, and a fresh-air duct (18) which adjoins the inside of the perforated armour plate (12) and which has a fan (20) for sucking the fresh air necessary for running the vehicle into the duct via air intake openings (16) in the armour plate. A wall section (22) of the fresh-air duct (18) situated between the air intake openings (16) and a heat-generating source (24) in the vehicle is air-cooled.

Air intake for a motorized vehicle, for obtaining a low radar and infrared signature of a ballistically protected air intake (10) of the vehicle, in which a heat-emitting source (24) in the vehicle is placed in immediate proximity to the air intake (10), comprising:
- a perforated armour plate (12) lying level with an outer bodywork plate (14) of the vehicle, and
- a fresh-air duct (18) which adjoins the inside of the perforated armour plate (12) and which has a fan (20) for drawing the fresh air for running the vehicle into the duct (18) via air intake openings (16) in the armour plate (12),
- wherein the fresh-air duct (18) has an airflow-deflecting wall section (22) situated between the air intake openings (16) in the armour plate (12) and the heat-emitting source (24), which wall section (22) is provided with at least one air bypass duct (26) for cooling the wall section (22).
Air intake for a motorized vehicle for obtaining a low radar and infrared signature of a ballistically protected air intake (10) of the vehicle, in which a heat-emitting source (24) in the vehicle is placed in immediate proximity to the air intake (10), comprising:
- a perforated armour plate (12) lying level with an outer bodywork plate (14) of the vehicle, and
- a fresh-air duct (18) which adjoins the inside of the perforated armour plate (12) and which has a fan (20) for drawing the fresh air for running the vehicle into the duct (18) via air intake openings (16) in the armour plate (12),
- wherein the fresh-air duct (18) has an airflow-deflecting wall section (22) situated between the air intake openings (16) in the armour plate (12) and the heat-emitting source (24), which wall section (22) is provided with at least one air bypass duct (26) for cooling the wall section (22), and
- the airflow-deflecting wall section (22) is configured as a double wall (28, 30) with an air bypass duct (26) lying in between.
An air intake for a motorized vehicle for obtaining a low infrared signature, comprising:
- a perforated plate with air intakes on an exterior surface of the vehicle;
- a fresh-air duct adjoining an inside of the perforated plate;
- a fan in communication with the fresh-air duct for drawing fresh air, for running the vehicle, through the fresh-air duct via the air intakes;
- and
- an airflow-deflecting wall section running parallel to the fresh-air duct and located intermediate the fresh-air duct and a heat-emitting source of the vehicle.
