Quelques news du SSJ



April 12, 2010, Zhukovsky, Moscow Region – Today the fourth Sukhoi Superjet 100 flight test prototype SN95005 flew from Komsomolsk-on-Amur to Zhukovsky-based Sukhoi Civil Aircraft Company Flight test center to continue flight certification campaign.

Flight certification campaign tests scheduled for this aircraft include the evaluation of on-board equipment and, together with 95004, systems failure safety. SN95005 will accomplish tests on both fire protection and inertial gas systems. Sukhoi Superjet 100 is the first Russian aircraft to feature inertial gas system .

Its implementation is a must according to the American and European aviation authorities introduced to enhance flight operation safety. Inertial gas system fills the fuel tank with nitrogen deployed from the air in proportion to the fuel consumed.

Its application allows preventing fire and detonation of fuel fumes in case of unfortunate critical landing, in particular, when the aircraft touches the runway with! the wing.

Further on, Sukhoi Superjet 100 SN95005 will be the vehicle for first customers’ pilot training. “Today the entire company is focused on certification campaign and aircraft production for our first customers. We sustain dynamic pace not only in terms of flight campaign, but also in fatigue tests.

Novosibirsk had already performed over 4950 laboratory flights, by the month end this shall equal 6000. In terms of static testing we are successfully through the main part of operational and design loads, only particular cases are left – such as passenger chair installation strength, etc. By the end of April we expect to power the first ramp-up production aircraft 95007. The key factor now is to have all partners on the project to enlist all efforts in reaching the outlined milestones”, - noted Vladimir Prisyazhnyuk, Sukhoi Civil Aircraft Company President, upon fourth Sukhoi Superjet 100 flight test prototype SN95005 arrival to Zhukovsky.


4 avions en vol, pour tester notamment le système d'inertage du carburant et débuter la familiarisation des pilotes

Le production en série débute avec l'avion n°7

Reste donc les moteurs

Bonne journée

Bonjour à tous.

Le numéro d'Air International de mai rappelle quelques éléments du projet SSJ.

Les problèmes chez NPO Saturn sont les suivants :

- situation financière proche de la banqueroute.

- perte (départ?) de centaines d'ingénieurs

- problèmes de qualité et d'assurance qualité

Sur ce dernier point les pâles de la soufflant ont du être finalement prises en charge directement par Snecma.

Gros souci donc.

Le carnet de commandes pour la version 95 (seule version commandée) s'élève à 145 ferme. soit plus que les Cseries il me semble. Même si l'essentiel des commandes est dans la sphère russe, on peut rappeler que Malev fait partie des clients.

Certification toujours prévue pour le milieu de l'année avec mise en ligne chez Aeroflot et Armavia cette fin d'année.

À vérifier (là j'écris dans le train pour poster ça plus tard quand j'aurais accès à une connexion) parmi les points forts du SSJ :

- largeur de cabine à 3.23 m plus large que la concurrence permettant une config 2+3 en éco et 2+2 en business confortable notamment au niveau du couloir (combien de plus que les autres? Est-ce que ce n'est pas trop pénalisant en poids et traînée?

- gain de 10% sur la consommation

- 10% de réduction sur les coûts d'opérations

À voir si les promesses seront tenues.




À venir peut être un jour des variantes 110 et 125 places qui ont à priori été intégrées dans
l'étude technique de la cellule du SSJ de 95 places. Est-ce que le powerjet aura les réserves de puissance et le consortium de motoriste le droit de présenter des moteurs plus puissants sans faire trop d'ombre à CFM.

Personnellement je trouve que cet avion à une bouille sympathique.


Le projet est intéressant, pourvu que les pb moteurs soient réglés




Bonne journée.

Lao start-up carrier plans to take up to nine Superjet 100s
By David Kaminski-Morrow

Sukhoi has secured another tentative customer for its Superjet 100 after a start-up Lao carrier, identified as Phongsavanh Airlines, signed for up to nine of the type.

The airline has signed a memorandum of understanding for three firm aircraft and six options.

Sukhoi says the deliveries would be scheduled for 2012 if the order is finalised. It values the potential order at $95 million at catalogue prices.

"I'm sure that with the Superjet 100's vast operational flexibility it will become the best tool for our growth-driven strategy," says the Lao carrier's owner, Od Phongsavangh, who is also chairman of Phongsavangh Bank.

Sukhoi has yet to certify the PowerJet SaM146-powered Superjet, which has logged some 1,700hr of flight testing.

Bonsoir à tous,

Le SaM146, moteur du SuperJet, vient de terminer ses tests de certification. Le moteur sera donc certifié d'ici quelques semaines par l'Agence européenne de sécurité aérienne (EASA), puis celle du Registre de l'aviation de Russie et les livraisons pourront ensuite débuter.
En tout, 7000 h de tests, dont 3500 en vol, et pour finir l'ingestion d'oiseau mercredi dernier.

Quelques nouvelles, qui ne sont pas totalement fraiches pour autant

http://www.flightglobal.com/articles/2010/06/08/342980/picture-superjet-completes-water-ingestion-trials.html



completed runway water ingestion trials at the company's test centre in Zhukovsky near Moscow.
The tests using Superjet MSN 95003 confirmed that the aircraft's two PowerJet SaM146 engines and auxiliary power unit continued to operate normally while travelling along the wet runway at a full range of speeds preceding take-off.
For the tests, a 70m (230ft) -long pool was constructed on the runway and filled to a depth of 40mm (10in).
The aircraft completed 27 runs at speeds ranging between 10kt (19km/h) and 150kt at different engine settings including low speed, take-off and maximum reverse thrust. The tests were monitored by the Russian certification authorities.





Juste pour rappeler qu'on attend la certification de manière imminente

1) la certification des moteurs devrait tomber dans la journée. C'était à priori un point bloquant
2) les outils de support à la formation des utilisateurs se mettent en place. Et notamment ce simulateur à l'usage des PNC pour simuler les évacuations

http://www.flightglobal.com/articles/2010/06/23/343586/picture-superjet-internationals-evacuation-trainer-is-put-through-its.html



A Sukhoi Superjet 100 evacuation trainer will be ready for use in the instruction of flight and cabin crew at SuperJet International's training centre in Tessera-Venice by the end of July.
The Alenia Aeronautica/Sukhoi joint venture offers flight and maintenance training for the Russian 100-seater twinjet. The cabin training device, built by Electronic Design and Modelling, is undergoing acceptance testing at the company's Manchester facility.
As well as being able to simulate anomalies such as a door jam or slide inflation failure, the trainer incorporates smoke and fire generators and is installed on a tilting platform support to reproduce cabin angles for emergency evacuation after a landing gear collapse.

Sukhoi to revise Superjet service entry schedule
By Tom Zaitsev

Market entry of the Sukhoi Superjet 100 appears to be slipping towards the third quarter of 2010 because of delays in commencing serial production of the PowerJet SaM146 engine.

Sukhoi says its revised schedule to deliver the first Superjet examples to launch customers Aeroflot and Armavia, to be released over the next week, hinges on the supply of serially-built powerplants.

Sources at Sukhoi have expressed doubts that engines to equip first serial Superjets could be shipped sooner than July.

Russian industry and trade minister Viktor Khristenko has indicated that training of pilots for the new type should begin in the spring ahead of the Superjet's entry into commercial service, due to take place by the middle of 2010.

State Duma transport committee member Anatoly Lisitsyn expects Rybinsk-based NPO Saturn, a partner in PowerJet, to begin producing SaM146s in summer and build about 15 of them next year.

C'est quoi cette connerie ... this year ou next year ???

L'avion d'essai est bien bleu blanc rouge non ?

http://www.flightglobal.com/blogs/flightblogger/2010/07/superjet-poised-for-north-amer.html

Un très long article



Nearly a generation has passed since the fall of the Berlin Wall and the collapse of the Soviet Union, the bi-polar world of communist and capitalist economies has given way to an interconnected world of globalized competition and industrial integration often bolstered by state support.

With the commercial jet aircraft manufacturing landscape having dwindled to just four players over the past decade, that trend of industrial consolidation is set to reverse itself in the years to come. Russian aircraft manufacturer Sukhoi, best known for its portfolio of fighter aircraft, is the first in a spate of new entrants to offer a jetliner assembled solely in the eastern hemisphere, but marketed to the world.

Its product, the 100-seat SSJ100 aircraft, made its first flight from Komsomolsk-on-Aumr, Russia in May 2008. It is powered by two PowerJet SaM146 engines, and is the launch point of a new business model which aims to challenge the established airframers Embraer and Bombardier on a global battlefield, starting with entry into service by year's end with Russian flag carrier Aeroflot and Armenian carrier Armavia.

As the first new entrant to step up to the plate, Suhkoi Civil Aircraft (SCAC) solidfied its strategic partnership with Alenia Aeronautica, the civil branch of Finnemeccanica, in June 2006 with a 75%/25% development split. A year later forming Superjet International, a Venice, Italy-based joint venture between Alenia (51%) and Sukhoi (49%) that took the reins on global marketing and product support.

The road to it's year-end entry into service, like the Airbus A380 and Boeing 787, has faced two years of delay after its originally planned November 2008 first delivery slipped due to an over-optimistic development schedule and production issues on the aircraft's engine. The engine-maker now claims it is in control of those issues, and is now winding down its four-aircraft flight test program with the approaching first flight of its first production aircraft.

With next week's Farnborough air show marking just over a year since the new 100 seater's western
debut at the Paris air show, the Superjet is poised to announced new orders, including a fresh Letter of Intent from a North American lessor for up to 65.


The lessor, who did not want to preempt a formal announcement at the air show, says that Superjet made a compelling technical and aftermarket case for the SSJ against its Brazilian and Canadian competitors, calling the SSJ the "best 100 seater on the horizon."

That bold claim, says the lessor, is anchored by the aircraft's supplier list reads like a who's who of western aircraft manufacturing. While critics of the Superjet say the venture is no more than a state-funded exercise that defies natural market forces and an aviation anachronism amongst composite innovators, but that criticism ignores the reality of the underlying technology driving the program.

The environmental and flight control systems are supplied by Liebherr, hydraulic system from Parker Hannafin, auxiliary power unit from Honeywell, Goodrich wheels, brakes and brake system controls, Messier-Dowty landing gear, Zodiac-Intertechnique fuel system and a PowerJet engine, a joint venture between Snecma and Russian engine maker Saturn NPO.

Additionally, the Thales avionics are grounded on a foundation similar to the Airbus A380, says Superjet, with an Aircraft Full Duplex switched data network ( AFDX) and Integrated Modular Avionics ( IMA) core that exceeds its nearest competitors with full fly-by-wire architecture and RNP .3 precision navigation capability and CATIIIa autoland capability.

The systems integration stands in contrast to Cold War-era Russian-made jetliners which exclusively used homegrown systems that lacked interoperability and had a reputation for being unreliable.

The new engine in particular features Snecma technology built on the CFM56 integrated with Leap-X advantages, including one-third reduction in high pressure stages from 9 to 6, while Superjet claims a 12% fuel burn advantage over its single-class 100-seat competitors the Embraer E-190 and Bombardier CRJ900, driven by a lighter airframe with better payload range capability around 2,400nm due to the five-abreast seating.

Suhkoi and Alenia's business case does not center around a next generation material system like that of Boeing or Airbus, a revolutionary systems architecture or supply chain, rather it's foundation is rooted in established advanced technology and a new supercritical wing profile, all while aiming to offering the new jet for as much as 20% less than its competition on the market, with a pricetag of $27.8 million.

Superjet International's offices on the edge of Marco Polo International Airport in Venice are still coming together, says Giacomo Peretto, the joint venture's head of communications, but the empty desks of its future training center will soon be occupied by desktop training computers and belies both the new nature of the program, as well as its extraordinary ambition to break into the western market. Within a year, Superjet hopes to be training western pilots at this Venice facility. Russian pilots are already well into their flight training at a training center in Moscow.

Apture™️
by Jon Ostrower

Time and again, the established airframers say that the challenge to new market entrants is not designing, certifying and delivering a new jetliner, but the process of seeing it through its multi-decade service life.

"Think about Embraer at the beginning," says Peretto. "Who would have been willing to bet a dollar on a Brazilian plane?"

Peretto plainly admits that Superjet International has its work cut out for it, but that won't stop the company from trying. With first delivery to Aeroflot at the end of this year, Peretto sees the early service life of the Superjet as a proving ground for the aircraft. The central challenge, he says, revolves around validating the aircraft's performance and demonstrating that the maintenance partnerships the venture has formed to live up to western standards of airline operational reliability and maintainability.

The new customer says they've been provided contractual assurances from Alenia and SCAC that 98% of parts will be dispatched from strategic depots, such as the one being set up in Frankfurt in partnership with Lufthansa Technik Logistik, within three hours of receiving a service call and the remaining 2% within 72 hours.

"We are the new kid on the block, as we say," says Peretto. "We need this reputation. We have to establish a solid reputation, we try our best on our part, we have no doubt the aircraft will be built the right way by our partners in Russia, so I think there's ground based for a perfect mix. Now the market will tell."

The lessor, while declaring "absolute faith in the product" acknowledges that western airlines remain uneasy about Russian aircraft and whether the Superjet can be supported in service to the same level as its American, European, Canadian and Brazilian counterparts. By spreading the risk between lessors and airlines, the new customer hopes to deliver lower acquisition costs for operators, while ensuring that airlines feel they have an exit strategy if they are dissatisfied.

"We have put our money where our mouth is," says the North American lessor.

Bonjour à tous

En regardant chez les collègues :

http://www.airliners.net/aviation-forums/general_aviation/read.main/4855758/#menu27

Aviopic



Empty Operating Weight per seat.
SSJ100-95 = E-195 - 5% = E-190 - 13% = Cs110 - 16%
Normal T/O Thrust per seat.
SSJ100-95 = E-195 - 15% = E-190 - 28% = Cs110 - 42%
It seems that the SSJ is relative light and the CF's are rather old and heavy(but that's old news of course).
The GTF is obviously a lot heavier again.
Also the SSJ seems to have less thrust but then again it needs less as a function of weight.
As a result we can expect pretty good short trip economics as shown below.

Fuel 400 NM trip.
SSJ100-95 = E-195 - 20% = E-190 - 16% = Cs110 - 8%
Fuel 400 NM trip per seat.
SSJ100-95 = E-195 - 6% = E-190 - 12% = Cs110 + 4%
Both the E-195 and CS110 pay the price for weight on a short trip, the CS does well per seat though(guess it has more seats).
Obviously the CS will make up for the weight penalty on longer trips, In fact I don't consider the CS to be a RJ anyway.
All above is of course based on information available to me and might be off by a +/- percent or so.


R2RHO



SFC for the SaM146 is stated at 0.629lb/h/lb versus 0.68 for the CF34-8 and 0.65 for the CF34-10. So it's not revolutionay, but it's still an improvement. The better engine/nacelle integration of the Superjet should help too. PowerJet also claims 20% less parts than the CF34. Sukhoi claims an overall 10% fuel consumption improvement versus the competition. Sounds a bit high to me, but I would believe 7%. The 5-abreast configuration is not the best for a 70-seater (which may never get built IMO), but is probably a break-even for a 100-pax a/c, and would work very well if the 110-130pax stretch is built. And I trust that Sukhoi knows how to build efficient wings. I haven't seen any OEW numbers, nor much more other data, which would help a lot in comparing it against competitors.
(sources for my numbers: the respective manufaturer's websites)
