FIELD: aircraft engineering.SUBSTANCE: nacelle comprises upstream fixed structure, moving cowl and downstream variable-section nozzle. Moving cowl extends in variable-section nozzle and is set at fixed structure. Cowl can displace to vary the section of said nozzle. Nacelle comprises assembly that ensures aerodynamic integrity. Said assembly is arranged fixed structure and moving cowl and comprises resilient means that can contract and extend between fixed structure and moving cowl depending on cowl position.EFFECT: better braking at landing.12 cl, 17 dwg |
