Definition 1 of 2
Definition
A fixed or movable engine cowling component that surrounds part of the engine or exhaust path, used in thrust reverser systems to redirect or contain the flow of exhaust gases or fan air.
Plain English
A cover or sleeve around part of the engine that helps guide the air or exhaust where it needs to go.
Context Anchor
Seen in descriptions of turbine engine thrust reversers, especially where engine airflow is being guided or turned around for landing rollout.
Derivation
From Old English 'scrud,' meaning a garment or covering. The aviation use keeps the original idea: something that wraps around and covers a part.
Why Pilots Care
Understanding the shroud helps pilots recognize how thrust reversers work and why they are important for stopping on short or slippery runways.
Intuition Check
Do not think of a shroud only as a loose cover or cloth. In this aviation use, it is a shaped engine structure that helps direct airflow.
Example Sentence 1
On landing, the translating shroud slides aft to deploy the thrust reverser.
Example Sentence 2
During the walk-around the pilot checked the reverser shroud for cracks or debris that could prevent proper deployment.
