Foreign media said that the US Navy successfully completed the first test flight of aircraft using 3D printing key components.
The US Naval Air Systems Command issued a statement on the 2nd that the MV-22B "Osprey" tilting rotorcraft that took off from the Naval Air Station in Patuxent River, Maryland, USA, completed the test flight on July 29, the engine of the aircraft. A 3D printed titanium component is used on the cabin.
The project official, Major Travis Stephenson, said in a statement: "This flight is very smooth. I don't feel any difference on the plane." He is the pilot of the test flight.
According to the US Navy, the 3D printed component is one of four sets of components that secure the Osprey engine compartment to the main wing structure.
The titanium component used in this test was printed at the US Naval Air Warfare Center Aircraft Division in Lakehurst, New Jersey.
According to the statement, Liz McMichael, who leads the 3D team, called the test flight "a great first step" and a "game rule changer", which will completely reform the way the US military repairs fighters and develop new functions.
She said: "In the past 18 months, we have begun to decipher how to safely use the password of 3D printing technology . We will continue to study the 'Osprey', starting from this flight demonstration, gradually form a formal configuration replacement."
The US Navy stated that the July 29 flight demonstration was the first time a US Navy aircraft used a test flight to a "critical" printed component for safe flight.
The US Navy said the 3D team has decided to build and test six other key components for the US Marine Corps' three aircraft ("Osprey", H-1 and CH-53K helicopters) next year. These parts will be made of titanium or stainless steel.
