While relatively modern, the fact that there were four of them meant that the A380 was inherently less efficient than a twinjet like the Boeing 777, a large airliner that only needed two engines.

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 ...

For rocket engine development—with design and testing cycles measured in decades—this is incredibly ambitious. But the timeline is achievable because of how Noyron works, Kayser says.

Dubai, UAE — LEAP 71 has announced the next phase of its rocket engine program, scaling its computational engineering methodology to develop meganewton-class propulsion systems. Building on the ...

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 ...

The Mira prototype series relies on jet engines for takeoff, cruise, and landing, while incorporating an aerospike rocket engine for high-speed propulsion tests.

P&W and GE successfully passed the Detailed Design Review of their offerings for the U.S. Air Force’s next generation NGAP engine, expected to power the NGAD manned fighter. Pratt & Whitney and ...

India's IISc-incubated startup SpaceFields has successfully tested its innovative aerospike solid rocket engine, showcasing a peak thrust of 13.42 kN and peak pressure of 5 MPa. This test ...

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.

LEAP 71 has successfully hot-fired an Aerospike engine with 5,000 Newtons (1,100 lbf) of thrust, powered by cryogenic liquid oxygen and kerosene.

What’s more, the Aerospike engine represents a more efficient alternative to traditional rocket engines with bell-shaped nozzles. The MIRA II incorporates a dart-shaped nozzle, offering several ...

Aerospike engines, known for their unique design and efficiency, address a key challenge faced by traditional bell-shaped rocket nozzles.
