Publication number: 20220177149Abstract: An air inlet duct for a nacelle of an aircraft propulsion assembly includes an annular body and an annular air inlet lip with two coaxial annular walls, inner and outer, respectively. The inner wall defining a portion of an inner annular surface of the air inlet duct and the outer wall defining a portion of an outer annular surface of the air inlet duct. A control system translates the lip from a first position, in which the lip is attached to the body, to a second position, in which the lip is axially separated from the body. An annular row of grilles is translatably secured to the lip. The grilles are housed inside the body in the first position and extended from the body in order for an air flow entering the air inlet duct to pass therethrough in the second position.Type: ApplicationFiled: March 19, 2020Publication date: June 9, 2022Applicant: SAFRAN AIRCRAFT ENGINESInventors: Quentin Matthias Emmanuel GARNAUD, Antoine Elie HELLEGOUARCH, Nicolas Joseph SIRVIN
