Mission design at rocket speed

Planning space missions is traditionally a time-consuming and costly process. But the new Australian National Concurrent Design Facility (ANCDF), housed at UNSW’s Canberra campus, speeds things up so a mission can be planned in weeks rather than months.

Harnessing the expertise, design processes and software of the French Space Agency CNES (Centre National d’Etudes Spatiales), the UNSW team has created Australia’s first concurrent design facility.

The ANCDF allows engineers and scientists—both professionals and students—to design different parts of a mission in parallel rather than one after the other, which is the traditional approach. Read More about Mission design at rocket speed

Wheat that’s good for guts

A new kind of wheat high in resistant starch can improve intestinal health

Bowel cancer is the world’s third most common cancer. A diet that includes more resistant starch, a kind of fibre that feeds good bacteria in the large intestine, can make it less common. Resistant starch helps improve gut health and reduces the risk of conditions such as diabetes, obesity, heart disease and cancer.

Since 2006, CSIRO scientists have been working in a joint venture with French company Limagrain Céréales Ingrédients and the Grains Research and Development Corporation to develop wheat with more resistant starch. Read More about Wheat that’s good for guts

Improving rail safety in Indonesia and Australia

The sweet spot for rail repair vs efficiency

Computer models to predict how railcars will respond to different track conditions are being developed by Indonesian and Australian researchers, to improve rail safety and efficiency in both countries.

They’ve already created a successful model for passenger carriages, which has been validated against the performance of trains in Indonesia. Now the researchers are working on models for freight trains.

“For railways, it’s standard practice to measure the conditions of the track periodically,” says Dr Nithurshan Nadarajah, a research engineer at the Institute of Railway Technology at Monash University.

3D printed rocket engine – backgrounder and links

Quick facts

  • A joint Monash University/Amaero team of engineers successfully designed, built, and tested a rocket engine in just four months
  • The engine is a complex multi-chamber aerospike design
  • Additively manufactured with selective laser melting on an EOS M280
  • Built from Hasteloy X; a high strength nickel based superalloy
  • Fuel: compressed natural gas (methane); oxidiser: compressed oxygen
  • Design thrust of 4kN (about 1,000 pounds), enough to hover the equivalent of five people (about 400 kg)

The 3D printed or Additive Manufactured aerospike rocket engine is the result of a collaboration between a group of Monash University engineers and Amaero Engineering, supported by Woodside Energy and Monash University.

Engineers at Amaero approached a team of Monash engineering PhD students, giving them the opportunity to create a new rocket design that could fully utilise the near limitless geometric complexity of 3D printing.
