Analysis of the design suggests that rockets utilizing an aerospike engine can save around 40% in fuel usage. The improved thrust efficiency across the entire journey of a rocket's trajectory ...

So this design is not only tried and true, ... The aerospike engine—specifically the conical aerospike—looks quite similar to a conventional rocket and functions using largely the same ...

This isn’t the only generative design headed to space, and we’ve covered a few projects if you’re interested in building your own 3D printed rocket nozzles or aerospike engines.

In the ’60s, rocket engine design and manufacturing company Rocketdyne had tried to make the J-2T Aerospike, a toroidal aerospike concept intended as an improvement over the Rocketdyne J-2 ...

Since at least the 1950s, rocket engineers have wondered whether another nozzle design, known as the aerospike, could be a more efficient way to send humans to the stars.

Showing how far AI engineering has come, a new aerospike engine burning oxygen and kerosene capable of 1,100 lb (5,000 N) of thrust has successfully been hot-fired. It was designed from front to ...

The aerospike engine holds great promise for spaceflight, but for various reasons, has remained slightly out of reach for decades. But thanks to Leap 71, the technology has moved one step closer to… ...

LEAP71’s aerospike engine was manufactured as a monolithic piece of copper using industrial 3D printing, and the entire process—from design to testing—was completed in just a few weeks.

Aerospike rocket engines are the stuff of legend in the space industry. Conceived in the 1960s, their unique spiked-nozzle design promises better efficiency, reusability, and performance at all ...

Leap 71’s aerospike engine, printed as a single copper block with internal cooling channels, could not be inspected internally before firing. “We had to test blind,” Kayser says.

Theoretically, the design of aerospike engines maintains high efficiency across a wide range of altitudes, making it ideal for rockets that can go from surface to orbit on a single spaceship.
