3-D printed parts and MV-22s

Posted on by Leave a comment

An MV-22B Osprey at Patuxent River Naval Air Station, Md. completed a test flight outfitted with a titanium, 3-D printed link– termed additive manufacturing (AM) by the Navy– and fitting assembly for the engine nacelle. This link and fitting assembly is one of four that secure a V-22’s engine nacelle to the primary wing structure and will remain on the aircraft for continued evaluation. The flight was performed using the standard V-22 flight performance envelope.

“The flight today is a great first step toward using AM wherever and whenever we need to. It will revolutionize how we repair our aircraft and develop and field new capabilities – AM is a game changer,” said Liz McMichael, AM Integrated Product Team lead in a presser from Naval Aviation Enterprise. “In the last 18 months, we’ve started to crack the code on using AM safely. We’ll be working with V-22 to go from this first flight demonstration to a formal configuration change to use these parts on any V-22 aircraft.”

In the end, being able to craft parts while underway and out of rapid replacement from shore-side CONUS facilities can keep birds in the air in a pinch, which can mean the difference in mission capability and cutting ops short.  The Truman is already deploying with a 3-D printing suite and reportedly is working out just fine.

Harry goes 3D

Seagoing ships from the smallest trawler to the largest naval vessel have long dedicated precious space to repair lockers. With the 6,000 man crews of the floating nuclear-powered cities that make up the super carriers of the U.S. Navy, they have whole departments with dedicated shops that can meet electrical, sheet metal paint, DC, hull, aviation, and other needs.

Now, add a 3D printing shop.

From Stars and Stripes:

Within their first weeks of deploying in November, sailors already had created and “printed out” custom dust caps and a wrench. A sailor in the “fab lab” designed his own solution after he and others grew frustrated that an oil cup on a machine was too small for a funnel.

“It required at least two people to get all the oil in the cup, so I figured we have this technology here, why not try something that would make this task easier,” Petty Officer 2nd Class Raymond Lee said. “I came up with an extension that narrows the nozzle, cuts the manpower in half, ensures there’s no spilled oil all over the deck.”

Officials aboard the ship say ideas for using the printer are pouring in from sailors.

“I think the possibilities are endless,” Lee said.

The ‘fab lab’ consists of two 3-D printers, a desktop computer and a large flat-screen monitor with a wireless keyboard and mouse. The printers are similar in size and shape to a traditional desktop printer.
