- Abstract
- The major features and performance parameters of the Boeing 757 cabin ventilation system are described within the context of cabin smoke control. Two design changes were developed and evaluated. In the first design, additional ventilation outflow valves are located on the upper part of the fuselage and cabin ventilation is modified to provide air delivery in either the front or rear half of the fuselage. The second proposed design involves establishing the capability of reversing the ventiltion flow so that it enters at the cabin floor and exits into the ceiling air distribution ducts. The technical feasibility of the design changes was assessed through installation complexity, added weight, and estimated effectiveness. Elements requiring further study were also identified.
