Abstract
An air extraction unit taking the form of a body, the geometric shape of which makes it easier to incorporate into an avionics bay of an aircraft. The air extraction unit derives from a multipurpose approach to the operational components of the avionics bay of an aircraft aimed at achieving weight and cost savings. All of the elements of the air extraction circuit are arranged in a compact housing of the body and are protected by the structure thereof. The air extraction unit can be used as a floor of an avionics bay that can be walked on, with a lateral organization.
Claims10
An air extraction unit for an avionic bay of an aircraft, comprising:
- a body having a housing in which are arranged suction means and discharge means,
- said suction means being configured to aspirate airflows, hereinafter referred to as suction airflows, from the housing via a plurality of air tappings arranged on the body and to deliver said airflows outside the housing, the delivered airflows outside the housing being referred to as delivery airflows, via the discharge means,
- said air extraction unit comprising a plurality of airflow guide elements arranged in the housing so as to direct the suction airflows toward said suction means and isolate said suction airflows in an airtight manner from the delivery airflows,
- the body comprising a bottom and a lid, these two being substantially parallel to one another, and four side walls adjoining the bottom and the lid,
- each of the airflow guide elements being resistant to bending and having a first face fixed to an upper face of the bottom, and
- a lower face of the lid being fixed to each of the four side walls and to a second face of each of the airflow guide elements.
