#China's 3D-printed minimalist turbojet #engine completed its first single-engine flight test on Thursday, marking a significant breakthrough in the engineering use of 3D-printed engines. The new product is independently developed by the Aero Engine Corporation of China (AECC). The 30-minute flight reached an altitude of 6,000 meters and a maximum speed of Mach 0.75. More than three-quarters of the engine's weight comprises 3D-printed components, slashing the part count and enabling a lightweigh

🟩 Construction of a slurry supported diaphragm wall initiates with the excavation of a narrow trench using a mechanical or hydraulic grab. Throughout the excavation, a bentonite or polymer slurry is continuously circulated to provide hydrostatic support and prevent trench collapse. Upon reaching the specified depth, the trench remains stabilised by the slurry head until reinforcement cages are installed and the slurry is displaced by tremie placed structural concrete, forming a continuous load
