Do perpendicular planes exist?
Geometry is quite a large part in mathematics and it includes a lot of things. After algebra, geometry comprises the rest of the mathematics. Many calculations in higher studies are done using geometry. The plane is a part of geometry. When four lines are joined in such a way that four of them are non-collinear, then a plane is formed. All the four angles formed are equal in a plane. A plane is actually a two dimensional figure if considered theoretically. But it is easier when considered in three dimensions. When we are dealing with two planes, considering it in three dimensions will be better.

The advent of technology has left its imprint on every sector and defense cannot be ignored. With most of the armed forces in the world going in for modernization of their air forces, a lot of innovative fighter jets have cropped up. Designed to hit the enemy with precision, these fighter jets not only leave one amazed but also have the capability of causing large scale destruction.
Below are listed some of the top fighter jets in the world. Read on to have a better understanding on how these fighter planes have changed the pace of war across the world.

Airbus A 380 is undoubtedly the most expensive aircraft in the world. The aircraft since its days of inception made great news as the media was abuzz about the facilities and the price tag with which the aircraft would come. The unit cost comes out to US $389.9 million making the Airbus A 380 the costliest of all the aircraft ever produced.

We all generally have an interest in things that flies in the sky. That thing might a living creature like birds or human made machine like an aircraft or spacecraft. We always wonder how they fly and always seem curious about facts related to aircraft. The history of aircraft is long and started when two Wright brothers tried to make a machine that can fly in the sky. Things started from there and now aircraft are one of the major means of transport we use to travel to different places.

Both the Eurofighter Typhoon and Dassault Rafale are among the high performing war machines, which has a history of serving the aerial battlefield landscapes. Eurofighter was seen entering the war arena by different defense forces from Australia, Germany, Spain and Saudi Arabia and British Royal air force. Similarly, Rafle too was seen being the part of the big and small nations’ air forces. The following are the comparison of the two.

The auto giant that has a renowned name in field of car design has come up with some thing sporty car hire spain. They have a concept design for a personal chopper that features a sports car like seating arrangement and has a glass body to provide an ultimate view. This luxurious design can revolutionize the way of flying a helicopter.
Fuel Cell Aircraft Technology Tested Successfully
A novel aircraft designed by European flight engineers has made it to the annals of history by taking the first flight with its engines powered with fuel cell aircraft technology. It was observed that the aircraft displayed zero CO2 emission during its entire flight period.
The aircraft, known as the Antares DLR-42 is the brainchild of four collaborating organizations, namely, DLR( German Aerospace Center), Lange Aviation, BASF Fuel Cells and Serenergy. One of the developers from DLR, Johann-Dietrich Woerner proudly stated that they had improved the performance functionalities considerably and increased the efficiency of the fuel cells to such an extent, that a piloted aircraft could easily take off powered by only fuel cells. He also reiterated the potential of fuel cell technology in aerospace and applied fields.
Electricity with Hydrogen
The fuel cell technology worked on the principle that transfers hydrogen into electricity. The Antares made use of this principle to take flight successfully. The process takes place with a simple reaction involving air and there is no involvement of combustion in this process. The developers claim that a fuel cell powered aircraft could cover distances as far as 465 miles and remain in the air for up to five hours. Water is the other product obtained during this reaction.
Fuel Cell Technology
Fuel cells using hydrogen have zero percent carbon dioxide emission if renewable resources are used. This is great news for environmentalists as there will be no carbon footprints left. It can now be considered as a serious alternative to other forms of energy systems. However, hydrogen fuel cell technology is still in its nascent stage and may take a while before becoming applicable to wide areas in the aerospace sector. One thing is clear- the stability is sound even if the hydrogen is carried in external pods. This was well proven by The Antares that flew up to 170 km per hour.
The next focus would be in improving the service life of the fuel cells along with their efficiency. Josef Kallio, project manager at Antares was confident that the hydrogen fuel cell technology would be one of the popular technologies to reckon with, in the near future.
Eurofighter Typhoon Fighter-Bomber
The Eurofighter Typhoon has clearly established itself as the world’s leading Medium Multi-Role Combat Aircraft (MMRCA) or fighter-bomber, often triumphing over more stealth oriented bombers and fighters. The Typhoon is manufactured by an aviation consortium that goes by the name of Eurofighter led by the revered European Aeronautic Defense and Space Company (EADS). Introduced in 2003 after nearly 10 years of flight testing, the Typhoon has already found favor with the defense outfits of most leading nations, including Italy, Germany, Britain, and Austria.
The Typhoon’s state-of-the-art features
With cutting edge fly-by-wire features that prevent manual operations to exceed safety parameters, the Typhoon is also equipped with advanced and automatic air-to-air and air-to-surface threat monitoring systems. The Typhoon also incorporates one of the first speech recognition systems for non-critical cockpit functions which is validated and confirmed by visual and audio feedback. Armed with Sidewinders and AIM-132 missiles, the Typhoon can carry six of the Paveway series laser guided bombs. With a small radar signature and infra-red search and track features, the Typhoon manages to give conventional stealth fighters a run for their money.
A hot favorite with defense buyers
The Typhoon is most frequently compared to the Lockheed Martin’s F22 Raptor and the Rafale from Dassault of France. The F22 is now out of production, while the Rafale is nearly two decades old. Thus, it should not be a surprise that the Typhoon seems to show up on the shopping list of defense outfits from across the globe. Even though some nations have opted for the Rafale, the Typhoon clearly outranks it on every count. Many of the nations who have gone with Typhoon’s competitors are rumored to be renegotiating with Eurofighter too. With the Typhoon continuing to create records not only in sales, adoption and deployment, but also in endurance and fly-times, it is clear that the other players have something to worry about.
The Small Unit Space Transport and Insertion system also named as Sustain may come into existence in 2030. Roosevelt Lafontant, a former Marine lieutenant colonel now employed by the Schafer Corporation, a military-technology consulting firm working with the Marines, leads the effort. As we all know due to some political reasons it is not possible to fly in other nation’s air space that extend 50 miles from the Earth’s surface until a proper permission is granted. This big hurdle consumes a lot’s of time and makes it impossible for emergency troops to be transported at desired place instantaneously. Sustain is expected to insert troops any where on earth with in two hours and will not need any permission from other countries as a spacecraft would allow the U.S. to step over other countries and insert forces where they’re needed. The military labs are making efforts to explore new technologies necessary to make it happen, from hypersonic propulsion systems to new composite materials needed to make the vehicle lightweight yet strong.
