A Dubai company has test-fired a 3D-printed space rocket engine that uses an artificial intelligence model.
LEAP 71 fired the engine for 3.5 seconds, producing 500kg of thrust and roughly 20,000 horsepower.
It is the first liquid rocket engine to be developed in the UAE and uses computational modelling developed by the organisation.
The test, carried out at the Airborne Engineering site in Wescott, UK, on June 14, marks a significant step forward for the artificial intelligence-based engineering industry in the Emirates.
Lin Kayser, co-founder of LEAP 71, told The National that the data collected will help train and improve their computational models.
"The goal is to be able to autogenerate engines across a range of thrust/propellant ranges, so each engine can be customised," he said.
The artificial intelligence model, called Noyron, involves an algorithm that can generate rocket engines, including software codes that command the engine how much thrust and propellent it needs to have.
It then powers the engine without any human intervention.
In this test, it powered the rocket using cryogenic liquid oxygen and kerosene fuels.
"We chose them (the fuels) because they are 'hard' propellants to use – so many start-up companies try to get by with simpler fuels," explained Mr Kayser.
"Liquid oxygen is not easy to handle because it is cryogenic. It can, for example, freeze kerosene in the cooling channels and then the rocket explodes.
The computational model is market-ready and can be used to produce functional rocket engines

co-founder of LEAP71
"We wanted a challenging combination that is quite common in larger rockets, like the SpaceX Falcon 9, but unusual for smaller chambers like ours. Smaller chambers are very hard to cool because you have little surface area."
Mr Kayser said Noyron is close to market-ready, but they will carry out more tests on engines that different companies are developing.
"From our side, the computational model is market-ready and can be used to produce functional rocket engines. This is what the test showed," he said.
LEAP 71 has a partnership with Europe's The Exploration Company, which is developing and manufacturing a reusable space capsule called Nyx.
It marks a big win for the start-up as it looks to sell its AI model to more players in the space industry.
"Our customers, like the Exploration Company, will bring engines based on our AI model to the market," said Mr Kayser.
"The engines will not be manufactured and sold by LEAP 71, as we are focused on the computational model side. But without real-life feedback, we cannot perfect our AI."
The company hopes its AI model could help revolutionise the way spacecraft systems are developed, including helping to reduce costs and speed up the construction of those technologies.

Keep it fun and engaging
Stuart Ritchie, director of wealth advice at AES International, says children cannot learn something overnight, so it helps to have a fun routine that keeps them engaged and interested.
“I explain to my daughter that the money I draw from an ATM or the money on my bank card doesn’t just magically appear – it’s money I have earned from my job. I show her how this works by giving her little chores around the house so she can earn pocket money,” says Mr Ritchie.
His daughter is allowed to spend half of her pocket money, while the other half goes into a bank account. When this money hits a certain milestone, Mr Ritchie rewards his daughter with a small lump sum.
He also recommends books that teach the importance of money management for children, such as The Squirrel Manifesto by Ric Edelman and Jean Edelman.
TOUCH RULES
Touch is derived from rugby league. Teams consist of up to 14 players with a maximum of six on the field at any time.
Teams can make as many substitutions as they want during the 40 minute matches.
Similar to rugby league, the attacking team has six attempts - or touches - before possession changes over.
A touch is any contact between the player with the ball and a defender, and must be with minimum force.
After a touch the player performs a “roll-ball” - similar to the play-the-ball in league - stepping over or rolling the ball between the feet.
At the roll-ball, the defenders have to retreat a minimum of five metres.
A touchdown is scored when an attacking player places the ball on or over the score-line.

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.”
