Engine Icing 787

Boeing warns of engine icing risk on 747-8s Dreamliners TOKYO Reuters - Boeing and General Electric have notified airlines about engine icing risk on 747-8 airplanes and 787 Dreamliners with some GE engines urging carries to avoid flying them near thunderstorms a Boeing official said. These phenomena do not necessarily occur together.

How Many Different Engine Variants Does The 787 Have

Boeing warns of engine icing risk on 747-8s Dreamliners.

Engine icing 787. Ice accretion can affect the external surfaces of an aircraft in which case it is referred to as airframe icing or the engine resulting in carburetor icing air inlet icing or more generically engine icing. Advised airlines on Friday about a risk of engine icing problems on its new 747-8 and 787 Dreamliner planes with engines made by General Electric. ENGINE AND APU START.

Since there is so much power available electronic heater blankets for anti-ice are feasible no other Boeing aircraft has the excess power to use electric anti-ice on the wings. Both airframe and engine icing have. Boeing advised airlines on Friday about a risk of engine icing problems on its new 747-8 and 787 Dreamliner planes with engines made by General Electric urging 15 carriers to avoid flying them.

The 787s engine-start and APU-start functions are performed by extensions of the method that has been successfully used for the APU in the Next-Generation 737 airplane family. On March 14 2016 the FAA already issued AD 2016-06-08 which was prompted by an incident on 29 January 2016. Boeing advises about 787 747 engine icing problems.

Typically they work in sections to reduce power demand and consist of. From Tu-95 1952 to Il-18 1957 to Tu-154 1968 I could give specific links but they are in Russian. By Alwyn Scott and Hideyuki Sano.

23 2013 338 PM PST. WASHINGTON Boeing is alerting airlines about possible engine icing problems on some of. In aviation icing conditions are atmospheric conditions that can lead to the formation of water ice on an aircraft.

The 787 is able to get away with this because it has very advanced electrical startergenerators. Perhaps most Russian larger aircraft had electrical wing de-icing system. The 787s nobleed systems architecture will allow the airplanes engines to produce thrust more efficiently all of the highspeed air pro duced by the engines goes to thrust.

Power consumption for this service is 45 to 75 kW. The issue affects 15 airlines including Lufthansa. In this method the generators are run as synchronous starting motors with the starting process being controlled by start converters.

FAA Mandates Engine-Icing Fixes That Could Affect Up to 150 Boeing 787 Jets Regulators find engines are susceptible to sudden in-flight shutdowns due to internal ice accumulation. Engine fixes ordered for 176 Boeing 787 Dreamliners at 29 airlines worldwide Urgent safety issue icing could force in-flight engine shut downs Boeing says. Federal Aviation Administration FAA issued a new airworthiness directive AD to reduce the likelihood of engine damage due to fan ice shedding on certain Boeing 787 Dreamliner aircraft powered by GEnx-1B engines.

Boeing warns airlines of engine icing on 747-8 787. Even B787 with its sheer electric supply cant afford anti-icing that is constant heating to prevent ice formation and de-icing power consumption is 45-75 kW. Anti-icing capability requires a power supply of 150 to 200 kW on an aircraft the size of a 787.

Pneumatic systems that divert highspeed air from the engines rob conventional airplanes of some thrust and increase the engine. The FAA ordered airlines to urgently modify engines on Boeing 787 Dreamliners due to an icing problem that can cause a specific model of GE engine. On the 787 the heater mats provide deicing service only at a temperature range of 45F to 70F 72C to 211C.

TOKYO Reuters - Boeing and General Electric have notified airlines about engine icing risk on 747-8 airplanes and 787 Dreamliners with some GE engines urging carries to avoid flying them near thunderstorms a Boeing official said. The generators can produce about 500 KW each significantly more than any other Boeing aircraft. SEATTLETOKYO -- Boeing has advised airlines about a risk of engine icing.

A irlines have been ordered to carry out an urgent fix on 176 Boeing 787 Dreamliners because of an engine icing problem. Advised airlines on Friday about a risk of engine icing problems on its new 747-8 and 787 Dreamliner planes with engines made by General Electric urging 15 carriers to avoid flying them near.
