简短问答
这类交通工具要看哪些本地机构或走廊规则？
先看本地视角中的型式认定、营运许可与枢纽——不要假定一份全球清单。
Is this a buying guide?
No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.
Are the scores official?
No. The six scores are relative editorial 0–100 marks across the 48 types on this site.
Where do the photos come from?
Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.
Why metric units?
Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.
How is this different from a wiki article?
Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.
安全运行运载火箭需要按相同顺序追踪能量、信息与机械流。
CBTC、ERS等通用缩写保留，并在上下文中解释。
原理
就运载火箭而言，Tsiolkovsky delta-V
就运载火箭而言，Mass ratio and exhaust velocity set achievable orbit—every kg of structure costs payload.
就运载火箭而言，Max-Q throttle
就运载火箭而言，Dynamic pressure peak forces throttle-down to limit aerodynamic loads.
就运载火箭而言，Gravity turn
就运载火箭而言，Pitch program trades vertical climb for horizontal velocity to reach orbit.
就运载火箭而言，Staging event
就运载火箭而言，Brief coast and sep must avoid recontact and plume impingement.
就运载火箭而言，Reusability trade
就运载火箭而言，Boost-back burns and heat shields consume propellant that could lift payload.
