A jet fighter that could affect the fate of World War II
In more than 100 years of aviation history, several innovations were real milestones that totally changed the image of aviation. One such example is without doubt introducing a jet engine. Messerschmitt Me 262 was the first combat aircraft used in this type of propulsion. A machine to help Hitler win World War II.
The early beginnings of jet technology
Contrary to popular opinion, jet engines were created relatively soon after the first Wright brothers plane crashed into the air. The first type of construction that can be classified as a full fledged jet engine is the work of English builder Sir Frank Whittle. In 1930 he designed and patented the first jet engine, initially designated as WU, and then W.1. This extremely simple from today’s perspective, the design with centrifugal compressor for its first flight onboard the Gloster E.28 / 39 jet had to wait more than 10 years. Faster, as already in August 1939, his first flight was made German experimental aircraft Heinkel He 178. It became the first jet aircraft in the world. Thus the German engineers overrun their English rivals. And real development of this type of construction was supposed to come only in times of World War II.
Messerschmitt Me-262 – how was the first mass-produced jet fighter of the world?
The experience gained during the design and flight study of He 178 was later added to the design of the Messerschmitt Me 262. Conceptual work on this plane began in 1938. The first hull pattern was presented a year later. After obtaining approval of the authorities of the Third Reich, the construction and testing of the first flight was commenced. The delay in the parallel-to-air engines of the Me-262 resulted in the Messerschmitt’s self-propelled fleets having flown with a 700 hp piston-type engine. Only jet engines powered by jet engines had to wait until July 1942. Junkers engines with the designation Jumo 004 were compliant with this version (previously the BMW gas turbines were abandoned due to their serious failure).
This innovative design still needed nearly a year to be fully ready for mass production. During this time, it was tested and tested on the fly. This process lasted for an additional six months, when unexpectedly Hitler ordered a change of concept and the fighter-bomber Me-262 was …
Chinese hackers have stolen confidential US anti-missile data
Data on US missile defense systems have been stolen by Chinese hackers – the Washington Post reported Tuesday. In Australia, the media report similar cyberattacks. Stolen data is important for the security of both countries.
Cyberslides have managed to steal secret construction plans or their elements, America’s most technologically advanced US missile defense systems Patriot PAC-3, THAAD, or Aegis, according to the Pentagon’s expert report, citing “WP”.
Data on F-35 and F / A-18 fighter jets, the V-22 Osprey multi-purpose vertical launch and landing aircraft, and the Black Hawk helicopter were also stolen, the Washington daily said.
Experts warn that such data obtained by Chinese intelligence can give you a colossal strategic advantage and at the same time undermine the US military superiority in the event of armed conflict.
High-ranking Pentagon officers who commented anonymously report that the acquisition of anti-missile defense data is part of Beijing’s extensive and intensified spying on not only American military structures but also Pentecostal civilian companies such as Boeing, Lockheed Martin, Raytheon and Northrop Grumman – writes “WP”. The newspaper adds that none of the companies commented on the report, stating that some of the information was stolen from their computer systems.
Hackers treat private companies working for the Pentagon as a weak link in the security system. “In many cases, these companies do not know they have been attacked by hackers until the FBI has knocked on their doors,” he said in a high-profile Washington Post interview.
In Australia ABC television reported Monday that Chinese hackers have stolen confidential plans to build a future Australian intelligence headquarters. On Tuesday the authorities refused to comment on this information, but they were not denied.
As explained by ABC’s cyber-security expert Des Ball, the acquisition of future intelligence headquarters plans, including details such as computer network information, makes the building exceptionally vulnerable to cyber-bullying or spy surveillance.
VirnetX wants Apple to make more money
Apple has been involved in patent infringement lawsuits against companies for years, but it is not itself against the use of technology owned by various companies. One company that has long struggled in court with US corporations is VirnetX, which is asking for millions more from it.
VirnetX has been filing with Apple since 2011, accusing the company of illegally using many of its technologies and is not groundless as it draws hundreds of millions of dollars in compensation from Cupertino. In 2012, Apple paid $ 368 million for patents related to VPN technology, and this year, VirnetX received $ 625 million in damages for infringing patents related to FaceTime technology.
These gigantic compensation apparently are not enough for the VirnetX boss, because the company is again demanding money from Apple. This time, the amount of claims is $ 190 million, and the case applies to FaceTime and iMessages.
The next process can be extremely painful for Apple, as VirnetX claims not only damages, but also the prohibition of using products that use conflicting technologies. If the court agrees, this will mean that Apple will be forced to give up its two flagship products that have been used in every US device.
Britons slim the rims
In sports cars, the key factor is performance, so designers are trying to lower it in all available ways so that the car can drive even faster. The British company BAC, together with Dymag, decided to take a few extra pounds off the rim, an inherent component of each car.
The enemy of racing cars is mass, because every kilogram you need to put on the move and stop, and the more they have, the more power they need. When constructing high-performance cars, unnecessary components are thrown away and lightweight composites are used to lower the weight.
Quite a few pounds in the rims, so Ford announced recently that his Shelby GT350R model will be equipped with carbon fiber wheels. The American giant is not the only company that goes in that direction and the same idea came from the British company BAC. The problem is that the carbon fiber rims are extremely expensive, so the British have developed hybrid wheels that are slightly cheaper, and at the same time 20% lighter than standard aluminum alloy wheels.
BAC wheels are therefore not made entirely of carbon but of aluminum, and of carbon fiber formed rims. Thanks to that, the 17 “wheels in size 7.5 x 17″ for the front axle weigh only 5.7 kg each, which is 23% less than traditional wheels. In the case of the rim, on the rear axle size 9 x 17 “, the weight savings are slightly larger and amount to 6 kg per piece. For even greater weight reduction, titanium screws were used, each weighing 30.2 grams, allowing each wheel to save another 212.5 grams.
