分数是本图鉴内的相对0–100分。用于浏览，不是工程规格。
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.
直升机的推进、结构、控制与安全在同一运行包线内耦合。先分清各系统名称与职责，便于故障模式与合规审查。
下方仪表为设计裕度、可维护性与人因的相对评分，用于同级平台比较。
系统
机体·翼面
就直升机而言，Swashplate tilts disk for cyclic and collective; blade pitch links set lift and control moments.
推力·燃油
就直升机而言，Anti-torque fan or tail rotor counters main rotor torque and provides yaw authority.
飞控·电传
就直升机而言，Gas turbine drives gearbox; freewheel unit allows autorotation if 发动机 quits.
航电
就直升机而言，Landing gear suited to pads, ships, and uneven terrain; ground handling wheels optional.
旅客·应急
就直升机而言，Rescue hoist and cargo hooks extend utility for EMS, offshore, and fire buckets.
环控
就直升机而言，Automatic flight control holds hover and approach profiles; GPS approaches to heliports.
相对量表
热点
就直升机而言，Mast bumping (teetering)
就直升机而言，Low-G maneuvers can exceed rotor flapping limits on some two-blade designs.
就直升机而言，Tail rotor drive
就直升机而言，Tail-rotor gearbox failures remove yaw control at hover power.
就直升机而言，Chip detectors
就直升机而言，Metal in gearbox oil signals impending gear or bearing failure.
就直升机而言，Hydraulic boost loss
就直升机而言，Manual reversion increases control forces beyond some pilots in IMC.
就直升机而言，Dynamic rollover
就直升机而言，Slope or skid snag on one side can pivot ship before pilot reacts.
材料
就直升机而言，Composite rotor blades
就直升机而言，Carbon skins over honeycomb balance stiffness with repair segments.
就直升机而言，7075 aluminum hub
就直升机而言，Rotor head components see high fatigue cycles from blade loading.
就直升机而言，Synthetic turbine oil
就直升机而言，High-temperature oil resists coking in hot section bearings.
就直升机而言，Kevlar fuel cells
就直升机而言，Crash-resistant bladders reduce post-impact fire risk.
