溫故知新系列之: 點解新飛機都係黃黃綠綠 (Aircraft Structure)
August 24, 2025
星期天又是輕鬆得黎要認真既一日, 溫下書…又學多一點點~ 點解新飛機都係黃黃綠綠? The paint used is a green zinc chromate or zinc phosphate primer, which manufacturers apply to newly built aircraft to prevent corrosion. 無意中又發現，原來HX (Hong Kong Airline) 係A350 launch airline https://www.airbus.com/en/newsroom/press-releases/2017-09-hong-kong-airlines-becomes-new-operator-of-the-a350-xwb 好…今日就簡單溫下 Chapter 3 : Aircraft Construction 咩係Aircraft? (又係back to basic 系列?) …突然唸返讀AOM 果陣學既野! https://applications.icao.int/postalhistory/annex_7_aircraft_nationality_and_registration_marks.htm#:~:text=According%20to%20Annex%207%20%2D%20Aircraft,heavier%2Dthan%2Dair%20craft. Aircraft is defined as any machine that

今晚搵到條好正既片 先從A350 hydraulic system 開始 https://youtu.be/10GaHtTpg-g 睇睇下吾對路 要多d認識再睇 bookmark先

Normal aspirate vs Turbocharger Engine?
August 7, 2025
今個早上繼續努力 讀書 我要做飛機師 🙈 首先，engine air induction 空氣有分normal aspirate and turbocharger 之後，就算turbo engine 都再分 supercharge and turbocharge, let’s get started 🙃🤪 Turbo vs Supercharger 先睇車既 https://youtu.be/DhTxCA65KWo https://youtu.be/iS0XxIcdcu4 再睇飛機既 https://youtu.be/o_MQ-5-Gii8 https://youtu.be/Xp0Vx8rVISc
Engine Detonation & Pre-Ignition
August 4, 2025
今日溫書…繼續Engine先~ 睇一下上年差吾多時間既發文…再收集一下新野: 溫故知新~ 我要揸飛機 XDDD 有一句說話好真…書第一次讀係知…第二、三、四、五次讀先會識…以前我真係讀書…知道佢UP咩…但未識…今晚一個人安靜下…睇返之知自己入左誤區都吾知 >3<” 今晚就一文搞清楚某D Terms 既分別! Reciprocating Engine v.s Turbine Engine Reciprocating and turbine engines differ primarily in their mechanism for converting fuel energy into motion. Reciprocating engines use pistons that move back and forth in cylinders, converting combustion pressure into rotational motion. Turbine engines, on the other hand, use
Start the engine

好…家下又溫下aicraft 既engine…到底飛機Engine 點著嫁呢? 呢個問題可以再細分為startup procedure and the working principle of the engine…當然細機同大機有不同原理! 由於每隻機 (吾同Model)都有少少分別…溫下theory~ 小型飛機 Ref : https://www.boldmethod.com/learn-to-fly/systems/how-does-a-plane-start/ ; https://www.faa.gov/sites/faa.gov/files/09_phak_ch7.pdf 小型飛機通常有一個Starting System (Ignition system) 去start the engine. It consists of the battery, ignition switch, and a starter motor. Of course, you may say the electrical circuit (lines and switch) is important. In general, we
Hand Propping
August 3, 2025
Ref: https://www.faa.gov/sites/faa.gov/files/regulations_policies/handbooks_manuals/aviation/airplane_handbook/03_afh_ch2.pdf Hand Propping General aviation aircraft can be hand-propped (manually started) due to a few key reasons: some aircraft are older and lack electric starters, others may have battery issues, and it’s also a method to check for potential hydraulic lock in the engine, according to aviation publications. While electric starters are common, hand-propping remains a
Skid and Slip (on rolling)
August 3, 2025
通常講skid and slip, 我地都好易聯想起在turn 既時候uncoordinated turn 果個 skid and slip…但實際在rolling 既時候都可能有skid and slip…今日又做下溫習~ 我地知道skid and slip係有分別…但點解家下普通airliner 配備既係”anti-skid system” 而不是”anti-slip system”? 呢個問題係幾有趣…首先…我地要從學揸車開始! Understeer (推頭) = Slip Oversteer (甩尾) = Skid Ball-out Skid Ball-in Slip 之後就要睇下下面呢條片2:39 當braking force 增加到某個程度就會引致Skid (而在飛機進入Skid 之前一定會有一斷slip既時間…但Slip 反而有助stopping the aircraft!) https://youtu.be/TQrBwJWzmAc?si=2as89SBGnTdyz0X7 要睇下家下D飛機既設計! https://youtu.be/vZmS661zijo?si=KGdV4sVmJrRthnP2 https://youtu.be/F3uqUDGKsZQ?si=DH8Zuk60jZdJsyQe Btw…turning after airborne 果個skid and
溫故知新之飛機BRAKE!
August 3, 2025
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
