Piccolo giudizio professionale: il risparmio di carburante del NEO è veramente apprezzabile!
Quanto in termini percentuali?
Apperò!Bella domanda...
Non credo si possa applicare una percentuale unica per tutto il volo, ma va visto per fasi. Ad esempio il decollo e la salita iniziale siamo attorno al 20% abbondante; la crociera è meno evidente, attestandosi tra il 10 e il 15%. Le riserve, invece, mettono quasi i brivide: laddove avevi bisogno di 2600kg per alternato più final reserve, ora ti bastano meno di 2200kg...
Altro esempio in avvicinamento finale: flaps full e gear down, con un CEO devii settare circa il 50% di N1, col NEO sei a 40% al messimo, a parità di peso, vento calmo.
NB: numeri spannometrici relativi alla versione A320 motorizzata Leap 1A.

Vietnam Airlines has taken delivery its first of 20 Airbus A321neos on order.
The aircraft is configured with 203 seats in a two-class setting: eight in business and 195 in economy. It will also be the airline's first short-haul jet to feature wireless inflight entertainment streaming product, which is set to begin on 1 December, says the Vietnamese carrier.
"Delivery of this aircraft is a momentous occasion that marks Vietnam Airlines' ongoing efforts to upgrade our narrow-body fleet as well as our 4-star service quality. We are confident that the Airbus A321neo fleet will further offer passengers high levels of comfort on growing domestic routes of Vietnam and Asia," says the airline's chief executive Duong Tri Thanh.

Primo A321neo per Vietnam Airlines
FG
Non vorrei sbagliarmi ma è una soluzione già utilizzata da bombardier sulla serie CS, adesso diventata airbus A220, quindi Airbus non ha avuto questa grande intuizione, semplicemente ha fatto sua un'idea di altrihttps://www.dailypost.co.uk/business/business-news/new-airbus-jet-could-save-16081748
A me sembra una piccola rivoluzione.
Caricare i trolley "a libro" invece che sdraiati qualcosa potra' cambiare. Se fanno stare 4 trolley nello spazio dove prima ce ne stavano 3 significa un aumento del 33%. Non male. Ovviamente con bagagli a mano eterogenei il risultato potrebbe essere diverso. Comunque la soluzione va in controtendenza rispetto alla tendenza di alcune compagnie di limitare il bagaglio in cabina. O forse va proprio a risolvere il problema alla base di queste regole.
Dulcis in fundo, e' possibile il retrofit degli A321 gia' prodotti.
Mi chiedo se si battera' la testa, e perche' nessuno ci abbia pensato prima.
E' la soluzione dei 737 sky interior, tra l'altro già presente - almeno in una soluzione simile - sui 32X CEO di Delta...
Dopo il 321 neo qualche mese fa, ieri è stato il mio primo volo col 320 neo. Sul primo avevo già notato una maggiore silenziosità rispetto al ceo ma, mentre su questo ero capitato davanti, sul 320 sono capitato in coda e la differenza è ancora più avvertibile. A parte che il sound dei motori, a terra, è completamente diverso e decisamente più quieto, in volo il confort acustico è due gradini più su.
Non ho ancora (fortunatemente...) volato sul 737 MAX ma vista la delusione del 787 non posso che trarre una conclusione: per quanto riguarda il comfort a bordo Airbus 3 - Boeing 0. La distanza fra i due ormai è nettissima
Concordo, con la donna bianca abbiamo provato 2 dei nuovi 321neo consegnati da poco a wizzair e il frullino non frulla piùSoprattutto in decollo, l'ho trovato molto più silenzioso. Ero in zona dietro le ali per capirci.
Airbus May Make the Next Version of Its Top-Selling Jet an Electric Hybrid
By Benjamin D Katz
Airbus SE is considering bringing the world’s first hybrid-electric airliner to market as it weighs its strategy for replacing the bread-and-butter A320neo narrowbody in the next 15 years -- a move that would mark a technological leap for the aerospace industry.
The European planemaker has grown confident that the revolutionary propulsion system will be ready for roll-out on an all-new single-aisle jet around 2035, according to people with knowledge of its planning. While the company has been public about its interest in hybrid engines, Airbus is now willing to consider powering its most important aircraft with the technology, said the people, who asked not to be named discussing internal deliberations.
Timelines aren’t certain and will shift as different capabilities evolve, the people said, adding that Airbus would start with a smaller single-aisle and work its way up to a size comparable to the A321neo, which seats as many 240 people. Any decision to move forward would also take into account market dynamics and competition with global rival Boeing Co., they said.
Airbus is still pursuing a conventional replacement for its A320 family, which started service in the late 1980s to compete against Boeing’s then-market leading 737. It is studying using redesigned wings, more composite materials, and tweaks to current engine architectures with higher bypass ratios to get to the 20% boost to fuel efficiency needed to justify an all-new aircraft. It has been earmarked as viable for production from 2030.
Though hybrid technology probably won’t be available until a few years later, Airbus is confident that airlines would be prepared to wait for the step-change in efficiency that a hybrid would provide, according to the people. (Airbus has targeted reducing CO2 emissions by 75% by 2050.) The decision will in part come down to whether Boeing decides to accelerate its own clean-sheet narrow-body design in the wake of the 737 Max crisis that has seen that aircraft grounded since March, they said.
Airbus has been working with Rolls-Royce Holdings Plc and Siemens AG on developing a hybrid engine, though that powerplant, due to be tested in the next two years, would develop 2 megawatts of power, far less than needed to propel even a small narrow-body model.
A spokesman for Airbus said its current narrow-body offering still has scope for further developments, while adding that Chief Executive Officer Guillaume Faury indicated last month that the planemaker is exploring hybrid options for future aircraft.
“For short range, there are many many different options. We’re not alone, we have to keep an eye on what the competitors are doing,” Airbus Chief Technology Officer Grazia Vittadini said in a May 22 interview at the planemaker’s headquarters in Toulouse, France. “We will have a new single-aisle at some point. Will it be green, will it be green-enabled? It will depend” on when it enters service.
The launch of a hybrid model, while the biggest advance in the industry for decades, would bring its own challenges, not least convincing airlines to back technology that might initially offer only limited range and capacity.
One design for a hybrid jet is to use a conventional engine mounted at the back of the plane to charge a battery, in addition to producing its own thrust. That would enable electric propulsion on each wing, augmenting power during takeoff and landing -- by far the most fuel-guzzling parts of a flight. The aircraft would operate at slightly lower speeds, adding, for example, about 30 minutes to a typical flight within Europe.
Carbon Footprint
An upswell in development of hybrid and battery-electric aircraft coincides with rising consumer awareness of the carbon-dioxide impact of jet emissions. The planes being shown now, however, are much smaller than the Airbus and Boeing narrow-bodies that form the backbone of regional travel across the globe.
Airbus is ultimately working toward a zero-emissions aircraft, though given the relative immaturity of the technology it’s likely to have to develop a hybrid model first, head of engineering Jean-Brice Dumont said at the May briefing.
A shift to electrical power would be disruptive for the manufacturing process, since propulsion would become more integral to the aircraft’s construction. Vittadini ruled out producing batteries but said management systems, heat exchangers and even the engines themselves could be within Airbus’s capabilities.
Most other developments are focused on smaller aircraft. Zunum Aero, backed by Boeing and JetBlue Airways Corp., aims to bring a hybrid-electric commuter model to market by 2022. MagniX Technologies Pty Ltd. is developing a propulsion system for an all-electric plane with a similar date in mind. Israeli startup Eviation is also going fully electric, with a nine-passenger plane making its debut at the Paris Air Show next week.
