Heat screening for jet engines, has hollow bulb shaped body held in jet outlet nozzle by arms, which feed cooling fluid into body; fluid is then evacuated through wall openings and downstream neck.
Heat screening for jet engines, has hollow bulb shaped body held in jet outlet nozzle by arms, which feed cooling fluid into body; fluid is then evacuated through wall openings and downstream neck.
The ejection nozzle of a jet engine consists of a channel (3) for the ejection of hot gas and a screening device, which consists of a flow body (6), in the form of a bulb, held in the centre of the outlet channel by the link arms (10). The body has an aerodynamic profile, adapted to the profile of the outlet channel and is terminated by a neck (12). The body is cooled by cooling fluid fed through the link arms.
