General Electric has printed and tested a turboprop engine


A division of General Electric Aviation conducted the full test of the turboprop engine printed on a 3D printer. Thanks to modern technology, time to develop a new engine has been reduced from ten to two years, and the number of parts to be reduced from 855 to 12, — writes resource

The engine was developed for Denali Cessina aircraft from Textron Aviation. Two years ago, the developers decided to print a fully functional engine and since far — now there are only a few final tests.

“This is not just another printing experiment. For us, the creation of printed engine — a turning point, because of the design and development, we have moved and have almost successfully completed the entire test cycle of a fully functional engine,” says head of development Paul Corkery.

A third of the engine is titanium part printed on a 3D printer. Reducing the number of parts from 855 to 12 reduces the engine weight by 45 pounds and reduce fuel consumption by 20 percent. Increased and the power engineers noted a 10 percent increase compared to a conventional engine of the aircraft.

After the tests finally show the performance of printed engine, it will only have to certify, after which we can safely launch them into production.
