The experimental rocket reached an apogee of 278 km, achieving the targeted speed of Mach 7.5 (seven and a half times the speed of sound). The team estimates that its engine could get you from London to New York in 35 minutes, and London to Sydney in 2 hours.
The experimental flight was undertaken as part of a joint research program, HIFiRE (Hypersonic International Flight Research Experimentation Program) being conducted by the Defence Science and Technology Group and the US Air Force Research Laboratory with Boeing and the University of Queensland providing expert technical design and analysis.
“The success of this test launch takes us one step closer to the realisation of hypersonic flight,” Dr Zelinsky said.
HIFiRE 5b is one of a series of 10 flight experiments under the Australia-US collaborative project Hypersonic International Flight Research and Experimentation program aimed at investigating physical phenomena of flight at more than five times the speed of sound. The knowledge gained from these experiments will be applied to develop future flight vehicles and testing of advanced air-breathing hypersonic propulsion engines known as supersonic combustion ramjets (scramjets).

Hypersonic flight, involving speeds of more than five times the speed of sound, has the potential to provide immense social and economic benefits.
“It is a game-changing technology identified in the 2016 Defence White Paper and could revolutionise global air travel, providing cost-effective access to space,” Dr Zelinsky said.
The program is aimed at exploring the fundamental technologies critical to the realisation of sustained hypersonic flight.
Boeing’s chief scientist for hypersonics Kevin Bowcutt said the HIFiRE program will accelerate the development of operational hypersonic systems by producing valuable scientific flight data.
Professor Michael Smart from the University of Queensland praised the highly skilled individuals involved in the program and said they were placing the Australian aerospace industry on the international stage.
The HIFiRE team has already achieved some significant milestones such as the design, assembly and pre-flight testing of the hypersonic vehicles and the design of complex avionics and flight systems. More test flights are scheduled in the next two years.
