Development hailed as a potential breakthrough in aircraft manufacture after university-CSIRO joint project prints two gas turbine engines

 

Australian researchers have created the world’s first 3D-printed jet engines, a breakthrough that could change the way aircraft are constructed.

Researchers from Monash University, aided by staff from the CSIRO and Deakin University, have printed two engines and put one of them on display at the International Air Show in Avalon, Victoria.

Monash and its spin-off company Amaero Engineering have registered interest from Airbus, Boeing and Raytheon, the defence manufacturer.

Researchers were given an old gas turbine engine by French firm Safran to copy, printing out two versions. The year-long process was led by Prof Xinhua Wu, the director of the Monash centre for additive manufacturing.

The aerospace industry is interested in the process of printing parts because of the reduced lead time, the lighter weight of parts and lower production costs.

Monash created the parts of the engine using printers that spread a very thin layer of metal powder across a base plate. A laser then formed the required shape using a computer-generated outline. This process was repeated over and over again until the part was completed.

“The project is a spectacular proof of concept that’s leading to significant contracts with aerospace companies,” said Ben Batagol, of Amaero Engineering.

“It was a challenge for the team and pushed the technology to new heights of success – no one has printed an entire engine commercially yet.”

The secret engine technology that made the SR-71 the fastest plane ever

On December 17, 1903, the Wright brothers flew the first airplane ever at 6.8 mph (10.9 km/h). Only 61 years and five days later, the Lockheed SR-71 Blackbird took off. It’s still the world’s fastest airplane with a speed of 2,193 mph (3,530 km/h.) This fascinating video explains its top secret engine technology.

It’s truly amazing that only 61 years and five days separate this

And it’s even more unbelievable that we haven’t been able to top that 51 years later (it will be exactly 51 years tomorrow—the first flight occurred on December 22, 1963.) Absolutely incredible.

Introducing the 777X   The 777X is a twin-engine, twin-aisle success redefined. We like to think of it as the future of flight unfolding. Building on the success of the 777 and 787 Dreamliner, the 777X is the largest and most efficient twin-engine jet in the world. Its folding raked wingtip and optimized span deliver […]
