Non pensavo che verniciare con colori diversi dal bianco le nacelle (del 787) potesse andare a interferire coi flussi aerodinamici....si impara sempre qualcosa di nuovo

http://www.flightglobal.com/news/articl ... es-385222/

British Airways' first Boeing 787-8 has emerged from the airframer's paint facility with its engine nacelles painted in the carrier's traditional blue scheme.

The colours mark a departure from the white nacelles which have featured on virtually all 787s delivered so far, a restriction which had resulted from laminar flow considerations.

BA's 787s are being fitted with Rolls-Royce Trent 1000 engines. The carrier's original publicity material had shown the aircraft with white nacelles.

But Boeing says it is evaluating customer requests to paint the nacelles on a "case by case basis".

"We need to evaluate each custom colour request because different colours may require different thicknesses to achieve the desired appearance," the airframer says.

"We need to ensure that the thickness required does not exceed the design tolerance."

British Airways' first 787 has been photographed at the Seattle production facility with blue nacelles, in contrast to the initial artistic impressions but in keeping with the scheme on the rest of its fleet.

Boeing says that specific discussions with its customers regarding the colours are "considered confidential".

The paint is crucial to the aircraft's economics because laminar flow reduces skin friction drag, and cuts fuel burn, but it requires a smooth surface with minimal boundary disruption.

Even the thickness of paint layers can interrupt the laminar flow between the engine inlet and the surface of the nacelle.

Qatar Airways' 787s have been painted pale grey, while other carriers have retained the white nacelles.

BA has ordered 42 787s of which the first 24 comprise eight 787-8s and 16 787-9s. The carrier is awaiting notification of delivery dates for the type.

studi così raffinati sul mantenimento del flusso laminare sono in contrasto con la tipica sporcizia sugli aerei francesi...
Spero che AF non abbia ordini di 787

Appunto, la progettazione è così estrema che quanche micron in più o in meno di vernice fà variare le performance???

I vettori che han ordinato il 787 dovran dotarsi di Aerolavaggio quindi????

"On Apr 26th 2013 the FAA released a new airworthiness directive 2013-08-12 superseding the emergency airworthiness directive of Jan 16th 2013 permitting the Boeing 787-800 to resume service after following steps have been taken: "Install main battery and auxiliary power unit (APU) battery enclosures and environmental control system (ECS) ducts; and replace the main battery, APU battery, and their respective battery chargers; in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB500003-00, Issue 001, dated April 19, 2013." As result of this new airworthiness directive a first Boeing 787-800 registration ET-AOP of Ethiopian Airlines took the skies on Apr 27th 2013 flying passengers from Addis Ababa (Ethiopia) to Nairobi (Kenya) as flight ET-801".

Se vogliono risparmiare sui consumi sì... e sono fortunati che il 788 utilizza solo natural laminar flow.
Per lo stab verticale del 789 è previsto l'aspirazione dello strato limite (in maniera passiva, senza pompe), per cui tanti bei buchini da tenere puliti

Boeing 787, problema durante prova volo

(ANSA) - TOKYO, 17 MAG - Un Boeing 787, apparecchio rimasto a terra per mesi in tutto il mondo a seguito di una serie di incidenti e ora alla vigilia di un ritorno nei cieli, ha avuto un problema elettrico durante un volo di prova in Giappone. Lo ha annunciato la compagnia All Nippon Airways (ANA), precisando che l'incidente non ha interessato le batterie, e che non rimettera' in discussione il ritorno il servizio dell'aereo sulle sue rotte, previsto per il primo giugno.

As Boeing 787s reenter service on routes around the world following the aircraft's prolonged grounding to resolve battery problems, the company is already working to address other issues that were emerging before flying ceased in mid-January.

Most of these problems, such as a string of failures concerning power panels in the electrical system unrelated to the later lithium-ion battery dilemma, fell into the “teething trouble” category that Boeing uses to describe early service life. These issues impacted the early dispatch reliability of the aircraft, giving it a percentage level in the high 90s, roughly similar to the initial performance of the 777-200 shortly after its entry into service in mid-1995.

Although the challenge of addressing many of these issues pales by comparison with the engineering resources involved with solving the battery problem, at least one concern with the operation of the auxiliary power unit (APU) has prompted Boeing and the unit's manufacturer, Pratt & Whitney Aero Power, to undertake a design revision. Operators have discovered that after the APS5000 APU is shut down with the inlet door closed after landing, heat continues to build up in the tail compartment. After 20 min., this causes the rotor shaft to bow, and the shaft takes up to 2 hr. to straighten again.

As many 787 operators, including All Nippon Airways (ANA), have flown the aircraft on shorter routes with reduced turnaround times, this has resulted in restrictions on when the APU can be restarted. An advisory bulletin from United Airlines says if an APU restart is attempted 20-120 min. after shutdown with the inlet door closed, the “bowed rotor shaft can cause turbine rub and significant damage.” If this occurs, an advisory message on the engine-indicating and crew-alerting system shows the APU failed to start and requires the unit to be inspected with a borescope.

Boeing acknowledges that “heat conditions have been found to sometimes influence 787 APU starting performance. As a result, operators have been provided with a revised operating procedure that has eliminated this finding. An improvement to the APU is being introduced in the next few months to remove the operating procedure.”

The revised operating procedure calls for the APU selector switch to be put in the “on” position during a shutdown, which will allow the inlet door to open and the the unit to cool down. The door must remain open for 40 min. before being closed, to enable the APU to be restarted. The notice indicates that the APU could be restarted without causing damage if reactivated within 20 min. of shutdown, or after 120 min. have elapsed.

The revised procedure also has connections with the operation of one of the 787's two lithium-ion batteries. The notice includes a precautionary note that advises against using the APU battery power to keep the door open as this will “only have about 15 minutes before being discharged.” It adds that ground power must be used to keep the APU door open for 40 min. and warns that, if this is disconnected, the door will close even with the APU switch on the flight deck remaining in the “open” position. Boeing declines to specify the design changes that will be made to improve cooling and ventilation of the APU compartment.

In the meantime, Boeing continues to modify the battery system on the last of the original 50 aircraft delivered up to the grounding in January. As of May 21, the company had completed work on 45, of which 40 had flown. It has also delivered the first two new 787s with the revised battery systems installed while still at the Everett, Wash., production site.

United resumed 787 flights on May 20 with a service between Houston and Chicago. The airline, which has six 787s, expects to bring its complete fleet back into service within days and launch international flights with the aircraft on June 10 with a service from Denver to Tokyo. Other long-haul flights, from Los Angeles to Shanghai and Houston to London, will be added in the summer months.

ANA will begin to resume services with its 18-strong 787 fleet on June 1, and plans to introduce the type on additional international routes later this summer including Tokyo Narita to Beijing and Shanghai, and Tokyo Haneda to Taipei. The increase will bring the number of overseas destinations served by ANA's 787s to five. Japan Airlines, which operates seven 787s, is also expected to resume flights on June 1, while Ethiopian Airlines became the first to operate the 787 on a commercial service since the grounding when it flew between Addis Ababa and Nairobi, Kenya, on April 27. Polish flag carrier LOT is scheduled to return its aircraft to service on June 5 with a flight from Warsaw to Chicago, while Qatar Airways resumed 787 services with a flight from Doha to Dubai on May 2.

Boeing 787: JAL, allarme batteria per nastro adesivo
Un pezzo di nastro adesivo su due fori di ventilazione: è bastato questo, secondo il Wall Street Journal, a far scattare l’allarme-batteria su un Boeing 787 di Japan Air Lines il 2 giugno scorso, riaprendo i timori circa la sicurezza degli accumulatori agli ioni di litio pochi giorni dopo la ripresa dei voli permessa dalla modifica dell’impianto. Altrettanto rapido l’accertamento del disguido, che non ha comportato un nuovo fermo della linea.
