Dubai company test fires 3D-printed space rocket engine

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
Lin Kayser,
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.

The Bio

Favourite holiday destination: Either Kazakhstan or Montenegro. I’ve been involved in events in both countries and they are just stunning.

Favourite book: I am a huge of Robin Cook’s medical thrillers, which I suppose is quite apt right now. My mother introduced me to them back home in New Zealand.

Favourite film or television programme: Forrest Gump is my favourite film, that’s never been up for debate. I love watching repeats of Mash as well.

Inspiration: My late father moulded me into the man I am today. I would also say disappointment and sadness are great motivators. There are times when events have brought me to my knees but it has also made me determined not to let them get the better of me.

Seven tips from Emirates NBD

1. Never respond to e-mails, calls or messages asking for account, card or internet banking details

2. Never store a card PIN (personal identification number) in your mobile or in your wallet

3. Ensure online shopping websites are secure and verified before providing card details

4. Change passwords periodically as a precautionary measure

5. Never share authentication data such as passwords, card PINs and OTPs  (one-time passwords) with third parties

6. Track bank notifications regarding transaction discrepancies

7. Report lost or stolen debit and credit cards immediately

Closing the loophole on sugary drinks

As The National reported last year, non-fizzy sugared drinks were not covered when the original tax was introduced in 2017. Sports drinks sold in supermarkets were found to contain, on average, 20 grams of sugar per 500ml bottle.

The non-fizzy drink AriZona Iced Tea contains 65 grams of sugar – about 16 teaspoons – per 680ml can. The average can costs about Dh6, which would rise to Dh9.

Drinks such as Starbucks Bottled Mocha Frappuccino contain 31g of sugar in 270ml, while Nescafe Mocha in a can contains 15.6g of sugar in a 240ml can.

Flavoured water, long-life fruit juice concentrates, pre-packaged sweetened coffee drinks fall under the ‘sweetened drink’ category
 

Not taxed:

Freshly squeezed fruit juices, ground coffee beans, tea leaves and pre-prepared flavoured milkshakes do not come under the ‘sweetened drink’ band.

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.”

Tips from the expert

Dobromir Radichkov, chief data officer at dubizzle and Bayut, offers a few tips for UAE residents looking to earn some cash from pre-loved items.

  1. Sellers should focus on providing high-quality used goods at attractive prices to buyers.
  2. It’s important to use clear and appealing photos, with catchy titles and detailed descriptions to capture the attention of prospective buyers.
  3. Try to advertise a realistic price to attract buyers looking for good deals, especially in the current environment where consumers are significantly more price-sensitive.
  4. Be creative and look around your home for valuable items that you no longer need but might be useful to others.
