溫故知新之飛機BRAKE!

過去好似收集過吾同Brake 有關既post…不過好似有D亂…今日一早就睇下吾同”交通工具/載具”既Brake!

Private Car: Disc Brake by normal spring mechanism!

Bus and Truck : Drum / Disc brake power by compressed air!

General Aircraft :  disc brake powered by Hydraulic (but only a master cylinder)!

B777, A350 : Carbon Fibre Brakes (disc brake) powered by Hydraulic!

B787, A220 : electrically activated braking system – electro-mechanical brake (EM brake)

睇返飛機師最常用既SKYbrary:

有樣野好易搞錯….首先要重溫既係Braking system 分兩大部分

1. The source of power 
2. The types of actuator

有趣既係 787  既brake system 不是用hydraulic!

Boeing 787 Dreamliner utilizes an all-electric brake system, a departure from traditional hydraulic systems in commercial aircraft. This innovative system replaces hydraulic actuators with electric ones, offering advantages in weight, maintenance, and performance.  (ref: https://www.safran-group.com/news/boeing-787-electric-brake-advanced-technology-meets-airline-requirements-2017-06-22#:~:text=Operating%20advantages%20for%20airlines,directly%20to%20the%20flight%20deck.)
