Dubai company builds 3D-printed rocket engines as big as Elon Musk's

An AI engineering company in Dubai is scaling up its 3D-printed rocket engines to match the size of Elon Musk's SpaceX Starship Raptors, which could redefine how next-generation space hardware is built.

Leap 71, which uses AI algorithms to design complex propulsion systems, is moving from small test engines to models powerful enough for full-scale orbital launches.

With major advances in metal 3D printing, the company says it can now produce engines nearly two metres across, sizes that were previously too large for 3D printers to handle.

“Our customers want to fly to space with our engines, so now we are scaling them massively,” Lin Kayser, co-founder of the company, told The National.

Unlike traditional aerospace companies that rely on teams of engineers to manually design rocket components, Leap 71 uses a computer system powered by AI to generate engine designs.

How does it work?

The AI model, called Noyron, involves an algorithm that can generate rocket engines, including software codes that command the engine how much thrust and propellant it needs to have.

Once the AI generates a design, it can be fed directly into a 3D printer to create the hardware.

“After an initial test last year, we test-fired eight more rocket engines, all of them different and designed by our computational system,” said Mr Kayser.

Until now, Leap 71’s engines have been relatively small, at about 30cm in diameter, making them useful for spacecraft like lunar landing vehicles. But to move into orbital launches, Mr Kayser said the engines needed to be much bigger.

The company is now developing engines that require industrial 3D printers with build volumes close to two metres. Such printers, which use metal powder to build parts layer by layer, have become available only in the past 18 months, driven mostly by rapid progress in China.

“There’s a number of 3D-printer manufacturers that can now support these extremely large-build volumes, which is really difficult because it’s tonnes of metal powder that go in into these things,” said Mr Kayser.

The company’s newer designs include meganewton-class engines, those capable of producing thrust in the range of 1,000 to 2,000 kilonewtons, putting them in the same category as some of the world’s most powerful rocket engines.

But those engines would still have to be test-fired to ensure they work as expected.

A key hurdle for Leap 71 is a lack of test stands, specialised sites where rocket engines are fired, in the country.

These are essential but difficult to build due to safety, noise and regulatory requirements.

Leap 71 hopes to set up its first rocket engine factory in the UAE, where it can take advantage of the country’s growing ambitions in space.

Sahith Reddy Madara, an aerospace engineer and founder of advisory firm Bumi & Space, told The National that Leap 71’s work could be a game-changer.

“What Leap 71 is doing represents a promising step towards redefining how we approach rocket engine development,” he said.

“This method could democratise access to advanced propulsion technologies, lowering barriers for smaller players by reducing the need for large in-house engineering teams and long development cycles. That said, widespread adoption will depend on how these designs perform under real-world conditions and whether they can meet the rigorous reliability standards of spaceflight.”

Expanding the market for rocket engines

Leap 71’s current business model is built around supplying what it calls “reference engines”, which are functional, baseline models that space companies can adapt to their own needs.

It hopes to eventually carve out a niche supplying engines that can power everything from small orbital rockets to larger reusable systems.

The company’s AI-led method can dramatically shorten development times and lower costs, which could be especially appealing to smaller or newer players in the space sector.

It already has a partnership with The Exploration Company, a European firm which is developing and manufacturing a reusable space capsule called Nyx.

The collaboration would integrate Leap 71’s AI-designed engines into future missions.

Sinopharm vaccine explained

The Sinopharm vaccine was created using techniques that have been around for decades. 

“This is an inactivated vaccine. Simply what it means is that the virus is taken, cultured and inactivated," said Dr Nawal Al Kaabi, chair of the UAE's National Covid-19 Clinical Management Committee.

"What is left is a skeleton of the virus so it looks like a virus, but it is not live."

This is then injected into the body.

"The body will recognise it and form antibodies but because it is inactive, we will need more than one dose. The body will not develop immunity with one dose," she said.

"You have to be exposed more than one time to what we call the antigen."

The vaccine should offer protection for at least months, but no one knows how long beyond that.

Dr Al Kaabi said early vaccine volunteers in China were given shots last spring and still have antibodies today.

“Since it is inactivated, it will not last forever," she said.

Low turnout
Two months before the first round on April 10, the appetite of voters for the election is low.

Mathieu Gallard, account manager with Ipsos, which conducted the most recent poll, said current forecasts suggested only two-thirds were "very likely" to vote in the first round, compared with a 78 per cent turnout in the 2017 presidential elections.

"It depends on how interesting the campaign is on their main concerns," he told The National. "Just now, it's hard to say who, between Macron and the candidates of the right, would be most affected by a low turnout."

Which honey takes your fancy?

Al Ghaf Honey

The Al Ghaf tree is a local desert tree which bears the harsh summers with drought and high temperatures. From the rich flowers, bees that pollinate this tree can produce delicious red colour honey in June and July each year

Sidr Honey

The Sidr tree is an evergreen tree with long and strong forked branches. The blossom from this tree is called Yabyab, which provides rich food for bees to produce honey in October and November. This honey is the most expensive, but tastiest

Samar Honey

The Samar tree trunk, leaves and blossom contains Barm which is the secret of healing. You can enjoy the best types of honey from this tree every year in May and June. It is an historical witness to the life of the Emirati nation which represents the harsh desert and mountain environments

Ziina users can donate to relief efforts in Beirut

Ziina users will be able to use the app to help relief efforts in Beirut, which has been left reeling after an August blast caused an estimated $15 billion in damage and left thousands homeless. Ziina has partnered with the United Nations High Commissioner for Refugees to raise money for the Lebanese capital, co-founder Faisal Toukan says. “As of October 1, the UNHCR has the first certified badge on Ziina and is automatically part of user's top friends' list during this campaign. Users can now donate any amount to the Beirut relief with two clicks. The money raised will go towards rebuilding houses for the families that were impacted by the explosion.”
