WebMar 11, 2014 · But that is not considered a Bleed system as far as a so called Bleedless Engine goes. The 787 engines still have VSVs, VBVs, Core Compt Cooling, Turbine Case Cooling and Stator Anti-Ice. Not using Bleed Air for pressurization and cooling makes it a Bleedless Engine for marketing. It does save a lot of weight without a lot of that ducting. WebThis is due to the higher cabin pressure and higher artificial humidity maintained in the cabin. The revolutionary feature of the 787 is the bleedless engines (i.e., air for cabin pressurisation is not compressed by the engines, unlike in almost every airliner). get a shave witcher 3
