Abstract
An aircraft duct structure includes a first duct through which exhaust air from a front-side equipment compartment flows, and a second duct through which exhaust air from a rear-side equipment compartment flows. The first duct has a terminal end part where the exhaust air inside the second duct flows into the exhaust air inside the first duct at a substantially right angle, and a flow straightening plate located inside the terminal end part. The terminal end part has a jet opening which faces, across a clearance, an air pressure regulating port where an air pressure regulating valve is disposed. The inside of the terminal end part is divided by the flow straightening plate into an upper region and a lower region. The exhaust air inside the first duct and the exhaust air inside the second duct merge together in the upper region.
