Wärtsilä's new 31 becomes the most efficient 4-stroke diesel engine in the world

By - June 22, 2015 4 Pictures

Finnish engine manufacturer Wärtsilä must be a fascinating place to visit. The company manufactures some of the most mind-bendingly enormous marine diesel engines in the world, like the record-breaking, 89-foot high, 44-foot long, 110,000 horsepower RTA96-C we wrote about more than 10 years ago. Now, Wärtsilä has another entry in the Guinness Book of Records ... for the world's most efficient 4-stroke diesel engine.

The European Space Agency (ESA) has successfully test fired a 3D printed platinum alloy thruster combustion chamber and nozzle. The world first test is further evidence that the 3D printing approach is a viable one for the aerospace industry, with the potential to cut costs by streamlining production methods and adding a greater level of flexibility in terms of supply and demand construction.

Retrofittable electric engine adds power and safety to light aircraft

By - June 10, 2015 5 Pictures

Small, single-engine aircraft are the mainstay of recreational flying, and provide many hours of generally safe enjoyment for hundreds of thousands of enthusiasts worldwide. However, with only one engine on-board, they are also often only a small malfunction away from becoming a heavy, unpowered glider in dire need of somewhere to land. To help improve this situation, researchers at Universidad Carlos III de Madrid (UC3M) and AXTER Aerospace have created an auxiliary electric propulsion unit designed to be installed in conventionally-powered light aircraft to both increase available power and provide extra range in the event of an engine failure.

Porsche working on variable-compression engine

By - April 26, 2015 2 Pictures
While the fashion in high-tech automotive developments might lean towards hybrids and electric vehicles at the moment, there’s still plenty of scope to improve the good old internal combustion engine and one of the holy grails of such development is the creation of a viable variable-compression-ratio system. Now Porsche is working on just such an engine, revealed in the form of a newly-published patent, which will be able to alter its compression ratio. Read More

GE announces first FAA approved 3D-printed engine part

By - April 19, 2015 5 Pictures
We've only just begun to see the huge impact 3D-printing technology will have on manufacturing, and the aerospace industry is a prime example. Earlier this year we saw the first example of a 3D-printed jet engine, now GE has announced the first 3D-printed part certified by the US Federal Aviation Administration (FAA) for a commercial jet engine. The fist-sized T25 housing for a compressor inlet temperature sensor was fabricated by GE Aviation and will be retrofitted to over 400 GE90-94B jet engines on Boeing 777 aircraft. Read More

Engine running on frozen carbon dioxide may power mission to Mars

By - March 10, 2015 1 Picture
Future missions to Mars may well be powered by carbon dioxide fueled engines, thanks to a recent prototype developed by Northumbria and Edinburgh Universities. Exploiting a phenomenon known as the Leidenfrost effect, researchers hope that their engine could be powered by the vast amount of dry-ice deposits found on the red planet, thereby reducing the need to transport fuel on interplanetary missions.
