Passenger boarding bridge incorporating air barriers

This invention describes an airport passenger boarding bridge that extends the comfortable indoor environment of the terminal all the way into a parked aircraft. It achieves this by using a specific horizontal air barrier positioned below the roof of the rotunda section, which connects to the terminal. The bridge can also include telescoping tunnels with inflatable seals at their joints to further maintain the environmental seal.

Why it matters: The fundamental engineering challenges and significant energy costs associated with maintaining a consistent environmental envelope across a large, dynamic structure like a passenger boarding bridge have not substantially changed since 2023.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedLarge-scale mechanical engineering, custom seals, environmental control.
