Kazan, Russia’s most dangerous nuclear attack submarine – an annotated infographic

April 19, 2017

Russia has floated its newest nuclear-powered multi-purpose attack submarine. The launch of Kazan, considered a counterpart to U.S. Seawolf and Virginia-class, comes as Moscow claims its submarine fleet has increased combat patrols to levels last seen during the Cold War.

The Kazan is the first upgraded Project 885M Yasen-class attack submarine.

Equipped with eight vertical missile launchers, it can deliver Kalibr or Oniks anti-ship and land-attack cruise missiles – significant after Russian ships and submarines fired long-range missiles from the Caspian and the Black Sea into Syria in 2016.

For the first time in Russian shipbuilding, the torpedo tubes are located not in the bow but just forward of the sail or fin, making room for a large Irtysh-Amfora spherical sonar system in the bow.

The Yasen subs also have six 650mm and two 533mm torpedo tubes that can also deploy mines and launch underwater drones.

Russia plans to build a total of seven Project 885M submarines. Goody, goody gumdrops.


#GreatBarrierReef off coast of #Australia hit by mass bleaching – an annotated infographic

April 18, 2017

Australia’s Great Barrier Reef is suffering from another massive bleaching event, the first time in memory such episodes have hit in back-to-back calendar years.

Experts fear the proximity of the two events gives the coral little chance to recover.

Key areas of the Reef suffered severe coral bleaching in 2016 and 2017.

Stream-ripping threatens music industry, as companies struggle to make streaming profitable – annotated infographics

April 18, 2017

As if a beleaguered music industry didn’t already have enough to contend with, the rise of streaming services like Spotify, Apple Music, Google Play Music, Pandora, Deezer and Tidal –  yes! even Tidal! – have changed the way many people listen to music. It has also brought about a new form of piracy, known as “stream ripping”.

This new type of copyright infringement has overtaken conventional music download piracy.

It’s not all days of wine and roses at the streaming companies, either. Spotify is the most successful streaming music service in the world and streaming is the music industry’s fastest-growing revenue source, yet none of the popular services has yet turned a profit.

Spotify has reportedly been in talks to acquire SoundCloud for some months now, but still no decisive action.


Fuels for life found on moon of Saturn – an annotated infographic

IET events this April – #engineering and technology dates for your diary

April 5, 2017


Throughout April the IET’s Local Networks are hosting a myriad of events, covering topics as varied as VLC applications through to the consequences of Brexit on innovation in the UK.

For those looking to hone their soft skills there are a number of lifeskills workshops taking place across Great Britain, but there’s also a wide variety of technical seminars and conferences if you’re looking to enhance your engineering knowledge.

When it comes to technical visits you’re spoilt for choice: with engineers in Asia invited to visit sites such as the DHL Asia-Pacific Innovation Centre and Qianhai Free Trade Zone. In the UK you can check out the Typhoon jet at RAF Coningsby or perhaps Tata Llanwern’s automotive finishing line.

Finally, for those looking for a bit of fun, why not go along to one of the network’s quiz nights? And for those in Cardiff, there’s an IET takeover of Techniquest!

#Aliens abound as Americans report record #UFO sightings 70 years after Roswell – an annotated infographic

March 14, 2017

The 1947 Roswell UFO incident took place 70 years ago this year.

Initially reported as a crashed weather balloon, it was later confirmed as a military surveillance balloon, but conspiracy theories of alien spacecraft persist and reports of UFO sightings have soared in recent years – peaking in 2014 with 8,621 reports.

The truth is still out there.

India’s AMCA stealth fighter – an annotated infographic

March 14, 2017

Preliminary design of India’s proposed Advanced Medium Combat Aircraft (AMCA) will begin in March, with a target of flying the aircraft in 2024 and making it ready for service as early as 2030. The twin-engine stealth warplane will likely feature an upgraded version of the General Electric F414 powerplant.

The AMCA is aimed at replacing much smaller ground attack jets such as the Mirage-2000, Jaguar and Mig-27. Russian technology includes Sukhoi stealth, active electronically scanned array or AESA radar and three-dimensional thrust vectoring for the AMCA’s engines.

#Formula1 #F1 2017 new rules – bigger, faster, more – an annotated infographic

March 10, 2017

New rules introduced for the 2017 Formula One season will bring the biggest changes to the cars in almost two decades, with revised aerodynamics and improved grip leading to faster racing.

The Formula One World Championship commences with the Australian GP in March and concludes in Abu Dhabi in November.

The new rules focus on bodywork changes which increase aerodynamic grip, the downforce, and new tyres which provide greater mechanical grip.

Africa’s Kariba Dam at risk of collapse – an annotated infographic

March 10, 2017

Work is underway to repair the Kariba Dam between Zambia and Zimbabwe, which is at risk of collapse due to eroding foundations.

Many problems are facing French engineering firm Razel-Bec, which is repairing the dam. The dam was first opened in 1959 and is holding back 180 billion cubic metres of water. We’d better hope the fix holds, eh?

Seven-planet extrasolar system discovered – an annotated infographic

February 24, 2017

We are not alone. Possibly.

Astronomers have discovered seven Earth-sized planets orbiting a star just 40 light-years away. At least three of them could harbour oceans of water, increasing the possibility they could host life.

This system has the largest number of Earth-sized planets yet found, making it a key object for future study.
