GE patents pulse-detonation core for a turbofan

On the subject of PDEs – pulse detonation engines – General Electric has just been assigned a US patent for a turbofan that uses a rotating pulse-detonation system, rather than low- and high-pressure turbines, to drive the fan and compressor. Basically, each turbine stage is replaced by a radial array of raked and angled pulse-detonation […]

GE Honda’s very small engine for very light jets

Does General Electric now have the widest range of aircraft engines in the industry, in thrust terms at least, following the first full engine run of a GE Honda HF120 in Japan? The HF120 demonstrator reached its maximum 2,095lb thrust on the first run. That is less than 2% of the power output of the […]

GE finds a Czech mate

Acquiring companies in Eastern Europe is becoming fashionable, it seems. Now GE is buying Walter Engines, the Czech company known for its low-cost PT6 alternative, the M601 turboprop.
