- the invention also relates to a nacelle comprising such a front frame.
- An aircraft is driven by several turbojets each housed in a nacelle also housing a set of ancillary actuators related to its operation and providing various functions when the turbojet engine is in operation or stopped.
- These ancillary actuating devices comprise in particular a mechanical thrust reversal system.
- a nacelle generally has a tubular structure comprising an air inlet upstream of the turbojet engine, a median section intended to surround a fan of the turbojet engine, a downstream section housing the thrust reversal means and intended to surround the engine room. combustion of the turbojet, and is generally terminated by an ejection nozzle whose output is located downstream of the turbojet engine.
- the modern nacelles are intended to house a turbofan engine capable of generating through the blades of the rotating fan a flow of hot air (also called primary flow) from the combustion chamber of the turbojet engine, and a flow of cold air (secondary flow) flowing outside the turbojet through an annular channel, also called vein, formed between a fairing of the turbojet engine and an inner wall of the nacelle.
- the two air streams are ejected from the turbojet engine by the rear of the nacelle.
- the role of a thrust reverser is, during the landing of an aircraft, to improve the braking capacity thereof by redirecting forward at least a portion of the thrust generated by the turbojet engine.
- the inverter obstructs the annular channel of the cold air flow and directs the latter towards the front of the nacelle, thereby generating a counter-thrust which is added to the braking of the wheels of the aircraft .
- an inverter comprises movable covers moved between, on the one hand, an extended position in which they open in the nacelle a passage for the deflected flow, and on the other hand, a retracted position in which they close this passage.
- These covers can perform a deflection function or simply activation other means of deflection.
- inverter with deflection grids also known as a cascade inverter
- the reorientation of the air flow is carried out by deflection grids associated with inversion flaps, the hood slides to aim at discover or cover the deflection grilles.
- the inversion flaps form locking doors activated by the sliding of the cowling generally generating a closure of the annular channel downstream of the grids so as to optimize the reorientation of the cold air flow.
