GE tested the world's largest aircraft engine in flight

The GE9X powerplant is designed for the 777X wide-body airliner. On March 13, an engine installed in the “flying laboratory” Boeing made its first flight, which lasted about 4 hours and was considered successful.

New composite materials used in the production of turbine blades and its nacelles, new heat-resistant ceramics and 3D printing made it possible to get by with 16 blades instead of 22, making the engine lighter and bigger; the diameter of the engine is almost equal to the diameter of the fuselage of the Boeing 737. The GE9X develops a thrust of 45 thousand kgf and spends 10% less fuel than the GE90 engine, which is used in the generation of the Boeing 777 flying now.

GE Aviation says that the new engine has already received 700 orders, including customers - Cathay Pacific, Emirates, Lufthansa, Etihad Airways and Qatar Airways. Now the engine is preparing for certification for civil aviation; in order for the installation to be recognized as operable and safe, it will take several more months of test flights: in particular, the operation of the engine will have to be checked at high altitude and in crosswinds.

I wonder how a nuclear reactor works and can robots build a house?
