As rocket engine construction using quick and unplanned disassembly, 3D printing technology will fuel the space race in the private sector



Today, 3D printing technology, through the use of heat-resistant metal alloys, has revolutionized the trial and error development of rockets.

A report from clarified that entire structures that previously would have required hundreds of distinctive components can now be printed in just days.

This means that one can expect to see many more rockets blowing in tiny places in the years to come, although the parts they are made of are set to get bigger and smaller as the rockets go. race in the private sector is strengthening.

Rocket engines produce the energy corresponding to the detonation by igniting a ton of TNT, as described in the Mars Society of Canada, second after second, directing this particular energy into an exhaust, reaching temperatures well above 3,000 degrees Celsius .

A technological innovation that fuels the space race

Such engines that handle this, minus a quick cover-up in an unprepared way, take about three years to design from scratch, the majority of which are taken care of by the cyclical process of redesign, referral, rebuild, and recurrence.

This is because rocket engines are extremely versatile. Additionally, the Saturn V F-1 engines that detonated Neil Armstrong made their way to the moon in 1969, each having 5,600 parts manufactured.

Many of these came from various suppliers and had to be welded separately or hand bolted, which was time consuming.

This long and expensive process may have been discovered in the 1960s, when the U.S. government poured money into NASA to fuel the space race, although for private companies it simply takes a while. time.

3d printing

Like this report, originally published in The Conversation, the key to rapid engine development is to reduce the number of parts, which shortens the time it takes to assemble the engine, as well as the disruption resulting from delays in the engine. Supply Chain.

The easiest way to do this is to change the manufacturing process. To date, space companies are moving away from so-called subtractive manufacturing processes, which remove material to shape a portion, towards additive manufacturing processes which accumulate a part by gradually adding material to it. It is then about 3D printing.

Gradually, as indicated in this report, engineers favor a process also called “selective laser” sintering to 3D print rocket engine parts in an additive process.

One such procedure works by first depositing a layer of metallic powder, before melting the shapes into the powder with lasers. Essentially, the metal bonds where it’s melted and stays powdery where it isn’t.

After the shape has cooled, an additional layer of powder is added and the part is built up layer after layer. In terms of rocket motors, then Inconel copper superalloy powder is used, because it can withstand extremely high temperatures.

Occurrence of RUD

Selective laser sintering allows multiple components to be printed in-house, in one piece, in just a few days. When an unforeseen quick disassembly or RUD takes place and the defect is detected, engineers can develop a solution through the use of 3D modeling software, incorporating very difficult parts into new rocket engines for testing. several days later, explained WRAL TechWire.

The use of 3D printing technology also helps manufacturers reduce the weight of the complete spindle, as fewer nuts, welds and bolts are required in the production of their multifaceted construction.

3D printing is particularly functional in making the complex regenerative cooled nozzle of an engine, which routes cold fuel around the hot engine into the walls of the engine at the same time and preheats the cold fuel before it is burned.

Building rockets, a costly initiative

Building a rocket doesn’t come cheap, the report says. Investors and stakeholders can become inconsistent as the RUD junk heap begins to pile up.

Companies vying to bring payloads into space put a strain on public relations every time they are forced to push back their launch schedules due to faulty rockets.

Indeed, brand new rocket companies, as well as space startups are embracing 3D printing technology on metal. It speeds up their stage of development, helping them get through the critical years before they manage to send anything into space.
