Boeing 설계 개념

Here’s a detailed look at the Boeing 787 Dreamliner, often referred to as the “787”:

Overview

• The Boeing 787 is a twin-engine, wide-body jet designed for long-haul travel. Its first flight occurred on December 15, 2009, and it officially entered service on October 26, 2011, with All Nippon Airways .

• Manufactured using advanced carbon-fiber composite materials, it delivers around 20–25% better fuel efficiency than previous-generation aircraft like the Boeing 767 .

Variants & Specs

Variant Length & Range Typical Seating

787‑8 ~56.7 m; range ~7,355 NM (13,600 km) 210–250 passengers

787‑9 ~62.8 m; seats ~290; range ~8,000 NM Stretched fuselage

787‑10 ~68.3 m; up to 336 seats (range shorter) Highest capacity

 

Unique Design Features

Utilizes bleedless architecture: more electric systems, less reliance on pneumatic/hydraulic power—boosting efficiency .

Engines: selectable between GE GEnx or Rolls-Royce Trent 1000, with connected electrical systems easing airline flexibility .

Noise-reducing chevrons on engine nacelles and raked wingtips improve performance and reduce cabin noise .

Operational History & Milestones

As of mid-2025, over 1,198 Dreamliners delivered, with 2,199 orders .

Carried over 1 billion passengers, doing so faster than any other wide-body aircraft .

Replaced older aircraft, enabling non-stop point-to-point routes formerly unfeasible for narrow-bodies .

Reliability & Safety

• Grounded temporarily in January 2013 due to lithium-ion battery fires; certified fix enabled a return to service by April .

• New quality-control issues arose in 2019–2022 (e.g., fuselage shimming), slowing deliveries; resumed by August 2022 .

• Major incident: Air India Flight 171 crash (June 12, 2025)—its first fatal hull loss, following engine flameouts due to fuel switch mishandling. Investigations suggest human error rather than mechanical failure .

Recent News & Orders

Gulf Air signed for 12 Boeing 787s with options for 6 more—highlighting ongoing confidence in the type .

Despite an ongoing safety investigation, Boeing still sees strong demand. Major airlines continue inspections following the Air India incident .

Why It Matters

1. Fuel economy and reduced emissions—leading edge for sustainable aviation.

2. Route innovation—opened markets for direct flights between secondary cities.

3. Passenger comfort—improved cabin pressure, humidity, and quieter interiors.

4. Industry impact—design and operational lessons deployed across future Boeing programs.
