Last October, a catastrophic rupture in the Aliso Canyon natural gas reservoir caused a methane gas spill that displaced more than 8,000 Californians and released an unprecedented 1.6 million pounds of methane into the atmosphere. Today, the Aliso Canyon leak is considered the worst in U.S. history, with aggregate greenhouse gas emissions said to outweigh those of the 2010 Deepwater Horizon oil spill.
NAVAL AIR STATION PATUXENT RIVER, Maryland (NNS) — Naval Air Systems Command (NAVAIR) marked its first successful flight demonstration of a flight critical aircraft component built using additive manufacturing (AM) techniques, July 29.
Did you know that even advanced gasoline engines waste roughly a fifth of their fuel? Especially at high engine speeds, some of the gasoline is used for cooling instead of for propulsion. With its new water injection, Bosch shows that it does not have to be that way. Particularly when accelerating quickly or driving on the freeway, the injection of additional water makes it possible to reduce fuel consumption by up to 13 percent. “With our water injection, we show that the combustion engine still has some tricks up its sleeve,” says Dr. Rolf Bulander, chairman of the Bosch Mobility Solutions business sector and member of the board of management of Robert Bosch GmbH. The fuel economy offered by this Bosch technology comes especially to the fore in three- and four-cylinder downsized engines: in other words, in precisely the kind of engines to be found under the hood of any average midsize car.
Siemens researchers have developed a new type of electric motor that, with a weight of just 50 kilograms, delivers a continuous output of about 260 kilowatts – five times more than comparable drive systems. This record-setting propulsion system successfully completed its first public flight today at Schwarze Heide Airport near Dinslaken, Germany, where it – almost silently – powered an Extra 330LE aerobatic airplane. The new drive system had already made its maiden flight on June 24th 2016. This advance means that hybrid-electric aircraft with four or more seats will now be possible. In addition, the company will be contributing this technology to the cooperative project that Siemens and Airbus agreed to in April 2016 for driving the development of electrically powered flight. Electric drives are scalable, and Siemens and Airbus will be using the record-setting motor as a basis for developing regional airliners powered by hybrid-electric propulsion systems. Siemens is determined to establish hybrid-electric propulsion systems for aircraft as a future area of business.
