The architecture is bleedless and replaces bleed air with electrically powered compressors and four of six hydraulic power sources with electrically-driven pumps while eliminating pneumatics and hydraulics from some subsystems, e.g. engine starters and brakes.[224] Boeing says that this system ...
electro-mechanically actuated carbon brakes and electro-mechanical actuator controllers. The system provides advantages over hydraulic brakes of digital control and monitoring, reduced weight and high reliability. The absence of hydraulic brake fluid avoids the risk of leaks and possible...
But overall I really enjoyed flying this Boeing 787 and the sounds are also excellent for a basic package like this. The first thought is that if this B787 had been a joint team product, with the already quality of the modeling and the creation of a full plugin (SASL) system, it ...
787 - 9 DATABASE * FULL TEST (1342 Questions, All topics in one test) * ELECTRICAL SYSTEM (198 Questions) * HYDRAULIC SYSTEM (74 Questions) * LANDING GEAR / BRAKES (79 Questions) * FLIGHT CONTROLS (274 Questions) * ANTI-ICE SYSTEM (60 Questions) ...
But the 787 design omits the heavier pneumatic system in favor of electric power for the hydraulic actuators. This change requires the aircraft’s two engines to drive four integrated drive generators providing 1.45MW of electricity, . The flight controls and landing gear depend on the elect...
The most notable contribution to efficiency is the new electrical architecture which replaces bleed air and hydraulic power with electrically powered compressors and pumps. Technology from the Sonic Cruiser and 787 will be used as part of Boeing's project to replace its entire airliner product line...
These unexpected difficulties have put them behind schedule in certifying the braking system, testing of the hydraulic system and in working on the midbody of one of the six test aircraft. According to Pat Shanahan, general manager of the 787 program, the problems do not change the schedule ...

提交时间:5 年以前 Boeing has issued an alert to airlines using its flagship B787 Dreamliner, warning that the switch used to extinguish an engine fire has failed in a “small number” of instances. The switch also severs the fuel supply and the hydraulic fluid to prevent flames ...
