With their capability to fly higher, farther, and more efficiently, jet engines have transformed air travel since their introduction. From its origins in the 1930s, the jet engine was a substantial ...

Five years ago, in 2021, American space agency NASA announced it is working on yet another project that doesn’t involve, well, space: the Hybrid Thermally Efficient Core (HyTEC). Since then, NASA’s ...

GE and Lockheed ground tested a new air-breathing hypersonic jet engine capable of powering missiles to speeds well in excess of Mach 5 in a smaller, cheaper, lighter, and more efficient package than ...

Rim-driven thrusters turn the normal propeller-motor arrangement inside out; rather than mounting the motor at the center of the propeller, they use a large hollow motor, with the blades attached to ...

Tests have shown that the existing engine architecture can accommodate 100% SAF, but for now the limit remains 50%. Why is ...

This was not a one-off experiment built for a headline. The hydrogen work followed a staged path, beginning in 2022 when easyJet and Rolls-Royce ran a modern AE2100 aircraft engine on 100% green ...
