In the creation of a hypersonic passenger aircraft overcoming the distance from New York to London in one hour, another step is taken. Orbital specialists at the NASA research center in Langley, Virginia, successfully tested a hypersonic engine printed on a 3D printer. The aircraft with such an engine will be able to reach speeds of up to 5500 km / h.

The combustion chamber of the engine was manufactured using the technology of layer-by-layer powder synthesis. It involves applying a powder alloy using a special 3D-printer with subsequent laser treatment. The tests were carried out in a wind tunnel for 20 days, which is a kind of record and is associated with the special operating conditions of the unique engine.

The tests in Langley confirmed the calculations of Orbital specialists regarding the design of the combustion chamber manufactured using 3D printing. Vice President and general manager of the company Pat Nolan said with optimism:

“This successful test motivates our engineers to create new systems, to use innovations to reduce costs and improve production efficiency.”
