Aircraft Cabin Smoke Control with Converging-Diverging Nozzles

摘要

The characteristics of converging-diverging nozzles are compared to those ofconverging nozzles for use in aircraft cabin smoke control. The peak flow flight regimes for the two different nozzles are compared by means of test data taken on a Boeing 757. The converging-diverging nozzle is shown as capable of maintaining peak volumetric flow over a wide range of airplane cabin pressure and flight altitude combinations. Sample capacities and flow schedules are presented for installation of converging-diverging nozzles in Boeing 737 aircraft. p3.
