Abstract
A device for maintaining and analyzing an aerodynamic probe of stagnation pressure type intended to be installed in an aircraft comprises a channel with a first end that is intended to penetrate into the probe, and an ejector fluidly coupled to the channel to create an air depression in said channel relative to the ambient pressure and a closed vessel recovering any particles sucked into the channel, the ejector and closed vessel being external to the probe when the channel is inserted into the probe. The ejector is coupled to a pressurized gas source and ejects gas in proximity to a second end of the channel opposite the first end to suction the air present in the channel and thereby create the air depression in said channel.
