What is the problem with the Boeing 787?
Last month, Boeing said some titanium 787 parts were improperly manufactured over the past three years, the latest in a series of problems to plague the wide-body aircraft. The defect was found as Boeing grapples with other problems in the 787 that have caused it to cut production and halt deliveries since May.
Does the 787 use bleed air?
On the 787, bleed air is only used for engine cowl ice protection and pressurization of hydraulic reservoirs. Instead, the compressed air is produced by adjustable speed motor compressors at the required pressure without significant energy waste. That results in significant improvements in engine fuel consumption.
How long can a 787 stay in the air?
The stretched 787-9, 206 ft (63 m) long, can fly 7,635 nmi (14,140 km) with 290 passengers; it entered service on August 7, 2014, with ANA.
What is so special about Boeing 787 Dreamliner?
One of the most unique things about the 787 is its raked wingtip, where the wing sweeps upwards at the end. It’s designed to give the aircraft more fuel efficiency and allow it to climb in a better way. It’s probably the first time we’ve seen this in commercial service.
How many 787 are built monthly?
Boeing said, “The current 787 production rate is approximately two airplanes per month.
What is the cost of a 787 Dreamliner?
Exclusive of discounts, the fly away list price of a Boeing 787-8 is US$248.3 million, a significant financial impost for many airlines.
Does the 787 have an APU?
The APS5000 APU was designed exclusively for the Boeing 787 Dreamliner. It is the quietest APU in its class with the lowest emissions in the industry. Pratt & Whitney APS3200 is the Airbus baseline APU of choice for the Airbus A320 family of aircraft.
How do airplane air conditioners work?
The air conditioning system is based on an Air Cycle Machine (ACM) cooling device, which is mostly used in turbine-powered aircraft. Packs remove the excessive heat from bleed air entering to packs from the aircraft bleed air system and supplies air to the cabin at the desired temperature.
What is the longest a plane can stay in the air?
Airlander The world’s largest aircraft which can stay airborne for up to three weeks and will be vital in delivering several tonnes of humanitarian aid has been unveiled.
Which plane can fly the longest?
What plane can fly the farthest in the world? The current record for the longest-distance commercial flight is held by a Boeing 777-200LR. This flight from Hong Kong International Airport to London Heathrow took the long way (vs. great circle distance) and was logged at 21,602 km (13,423 mi/11,664 nm).
Is the Dreamliner faster than other planes?
While standard planes are metal, the Dreamliner is made of something called composite – a combination of different materials. It means it’s stronger, lighter and more aerodynamic. The plane flies at Mach 0.85. That’s the equivalent of 640 miles per hour – about three times faster than a Formula 1 car at full throttle.
