HyShot Scramjet Project

• University of Queensland, Australia

What is a Scramjet?

• Engine which breathes oxygen at hypersonic speed
• Supersonic fuel combustion
• Needs hydrogen to run
• Gives off water as only byproduct
• Lighter than conventional engine while producing
  same power
• Reduce fuel load significantly by using oxygen
  from atmosphere

Scramjet History

• NASA X-43A (Hyper-X)
• 185 million
• Phase I unmanned
• 2 Jun 01 flight failure
• destruct
• U of Q HyShot
• 1.5 million
• 3 yr design and construction
• COTS
• International assistance

So what?

• Flight at virtually any speed and altitude
• Escape inner atmosphere and coast in near
  permanent orbit
• Flight from Sydney to London in 2 hours
• Lower cost of launching small payloads
• (e.g. Comm satellites)
• Technology revolution?
• Uses atmospheric oxygen compressed during ascent
