Singapore Special

The Concept

The Singapore Special is a hypersonic business scramjet concept that would fly at an altitude of 90,000 feet at Mach 2.5. It could transport 18 passengers from New York to Singapore under 6 hours using hydrogen as a fuel source.

Origin of the Concept

The Singapore Special concept was created to inspire future engineers and designers to create the next generation of faster business jets powered by greener fuels.

How It Works

The Singapore Special is a fixed-wing aircraft with scramjet motors strong enough to push a medium-sized rocket into orbit. In normal trans-oceanic flight it would be less taxed, making it more efficient and placing less stress on the engine at hypersonic velocity.

The Singapore Special will be able to fly at speeds of 1,650 mph at an altitude of 90,000 feet. This aircraft also reduces weight by having a lighter landing envelope. At Mach 2.5 and with a 10,000+ mile range, the aircraft could be on the other side of the planet in less than 6 hours. This is beneficial not only for commercial travel, but also during emergencies. The Singapore Special will be able to transport people away from areas of danger or deliver relief supplies faster.

In subsonic, The Singapore Special could cruise at Mach 0.95-0.99, which would result in 20% faster regional flights and thus lower operating costs. The main gear will use load-tensioning brakes (similar to train locomotives), which reverse polarity. This provides rapid braking capability without the possibility of catching fire.

Potential Market

Flight time alone would make The Singapore Special very attractive to potential buyers. Its ability to burn hydrogen would also be a key selling point. This type of super-fast aircraft could also be adapted to transport patients or organs around the earth when speed is a crucial factor.


The Singapore Special concept was imagined in February 2019. It was designed by Martin Rico, who studied design at the University of Buenos Aires and who also created the PDM25 urban airport for Imaginactive.
