#How to build a hypersonic airliner t is a magic aircraftthe pleasure of flying in it is almost a carnal one.
one of the world first supersonic civilian airplanes, which flew from 1976 to 2003 and became a watchword for travelling in style.
This thoroughbred airliner could fly from London to Sydney in 17 hours, three minutes and 45 seconds;
the only other civilian airliner able to break the speed of sound was the Soviet union Tupolev tu-144,
The end of the Concorde and Tupolev airliners left the supersonic market empty. But now, 12 years after the Concorde fleet last flew,
even faster airliners are taking shape in research facilities. One of those designs is by Lapcat-II,
a European-designed aeroplane capable of cruising speeds up to eight times faster than sound (8, 500 km h or 5, 280 mph) taking passengers from Brussels to Sydney in 2 hours and 55 minutes.
At the AIAA Hypersonic Space Plane conference in Glasgow in Scotland in July, a paper submitted by Lapcat-II researchers said their early airliner tests suggested such a design would be greener than current aircraft,
One is a Mach 5 plane the Lapcat-A2 powered by a precooled air-turbo ramjet;
and a promising Esa-designed Mach 8 plane, also powered by a ramjet engine. A ramjet is an air-breathing jet, with no major moving parts.
Ramjets can move a plane very fast. But how do you power them? Fuel choice is important,
In Asia, Japan aerospace exploration agency (Jaxa) is also working on a hypersonic airliner called Hytex intended to cross the Pacific ocean in two hours at speeds of Mach 5. Both Lapcat-II
says Hideyuki Taguchi, leader of Jaxa hypersonic airplane research. Hunger for hydrogen But, deriving hydrogen efficiently is one main factor for high operating costs.
Even though hydrogen-fuelled airliners would not emit greenhouse-increasing gases such as carbon dioxide, sulphur oxides or soot like today subsonic airplanes,
there is another issue. Water vapour produced by hydrogen combustion stays in the stratosphere for a long time and could be a contributing factor to global warming.
And that effect could be worse than the current fleet of long-haul airliners the longer that water vapour remains."
"Lapcat-II also plans for their Mach 8 Esa-variant airliner to fly well above 33 km, hopefully minimising the environmental impact.

and Boeing to design airplanes that break the sound barrier more quietly. From 2020 to 2025 it may be possible that airplanes could then exceed the sound barrier over populated land without causing a major disturbance.
In Europe, Steelant team tested their 300-seat design albeit a 1: 120 scale model, at speeds of Mach 8 within a wind tunnel.
While the design consumes two times more fuel per second than a Mach 4 plane, it gets to the destination in roughly half the time so the fuel consumed overall during the trip is roughly the same.
When we have a lighter airplane, we have lower fuel consumption and smaller tanks, which makes the vehicle again smaller,
The Jaxa project has studied the potential market for hypersonic airliners travelling at Mach 5 and found a 100-passenger aircraft flying two round trips per day is realistic based on market research.

#Airbus patents plane that could fly from New york to London in 1 hour A rocket-plane that could fly from Vancouver to Tokyo in three hours instead of 10 has been patented by Airbus. The U s. patent for an"ultra-rapid air vehicle
Airbus said the plane would be targeted mainly at business travel and VIP passengers"who require transcontinental return journeys within one day,
The document states that the supersonic plane could carry 20 passengers or two to three tonnes and reach up to 4. 5 times the speed of sound (Mach 4. 5) around 5 500 kilometres per hour.
the plane could cover the 5, 600-kilometre distance between New york and London, normally a seven to eight hour flight, in an hour.
However, that doesn't take into account that the plane wouldn't be at its top speed for the entire duration of the flight.
The plane would achieve its extreme speed with a combination of three sets of engines turbojets for taxiing, takeoff and landing;
The turbojets and rocket motor fold into the body of plane when not in use and the plane also has adjustable fins to make it more aerodynamic.
It would be fuelled by hydrogen and liquid oxygen. The speed of the plane would be double that of two previously built supersonic planes, neither

Airbus files patent for a hypersonic jet more than double the speed of Concorde A trip from London to New york could take just one hour
The aerospace manufacturer is designing a hypersonic jet that it hopes will take people between the two major cities faster than most daily commutes.
The US Patent and Trademark Office recently approved an application from Airbus for the new jet,
The jet is described as'an air vehicle including a fuselage a gothic delta wing distributed on either side of the fuselage,
and a system of motors able to propel the air vehicle.''The patent describes how three different types of engine,
powered by different forms of hydrogen, would work together to propel the vehicle at speeds of 3, 425mph (5,
500km/h). Two turbo jets would allow the aircraft to climb vertically at takeoff, before retracting into the fuselage just before it reaches the speed of sound.
A rocket motor would take it to an altitude of 100, 000ft (30,000 metres. The wing-mounted ramjets would then take control to push the jet to its final speed.
Airbus says it has designed the craft's aerodynamics to limit sonic boom, which was a major problem for Concorde
Passengers on the aircraft will be limited to 20.''In the case of civil applications, the market envisaged is principally that of business travel and VIP passengers,
Airbus thinks the jet would be able to complete trips such as Tokyo to Los angeles in just three hours.
The aircraft manufacturer says the hypersonic jet could also be for military applications, working to transport soldiers at rapid speeds.
But Airbus isn't the only one vying to create hypersonic aircraft technology. Last month, Air force bosses revealed they hope to have a hypersonic plane capable of crossing countries in minutes by 2023.
Several tests of hypersonic projectiles have already been carried out. Air force Chief Scientist Mica Endsley told Military. com that the Air Force and Darpa,
the Pentagon's research entity, plan to have a new and improved hypersonic air vehicle by 2023.
Experimental unmanned aircraft developed for the U s. Air force have gone already hypersonic during tests off the Southern California coast,
The new air vehicle could be used to transport sensors equipment or weaponry in the future, depending upon how the technology develops.

Reduced risk of damage during hard landings, by as much as a factor of five, compared to conventional landing gear Stable landing and takeoff on sloping terrain of up to 20 degrees, more than twice current limits and on craggy,
the landing gear is designed to let a helicopter touch down on sloping terrain up to 20 degrees, which is not currently possible,
compared to conventional landing gear. As well as working on new landing systems, Darpa is developing swarms of reusable drone aircraft that can work together to perform a mission,
which it has called the Gremlins program. The idea is to replace the expensive and increasingly vulnerable multi-function combat aircraft
Instead, they propose deploying from the air smaller unmanned aircraft, each with different capabilities, to perform a mission before retrieving them mid-air
fitting somewhere between missiles and conventional aircraft. The agency is hoping to build on its automated mid-air refuelling technology alongside the sea based platforms for capturing drones as they come into land.

A concept aircraft named Skreemr could reach speeds exceeding Mach 10-that's 10 times the speed of sound.
Liquid-oxygen or kerosene rockets would be fired to enable the plane to rapidly climb higher in the sky

and there is no suggestion the designs for Skreemr will ever become reality. Craft using scramjet propulsion systems are set to be smaller, lighter and faster,
Bombardier Skreemr's sleek design, with four wings and two large rockets on the rear, is intended to be used as a commercial aircraft to carry 75 passengers in luxury.
Airbus hopes its planned hypersonic jet which would travel at 4. 5 times the speed of sound,
Standard airliners take around eight hours to complete the journey. Airbus'jet is described as'an air vehicle including a fuselage,
a gothic delta wing distributed on either side of the fuselage, and a system of motors able to propel the air vehicle'.

#Solar-powered plane lands in Ahmedabad on second leg of world trip A Swiss-made solar powered aircraft landed in Ahmedabad on Tuesday night,
The world's first aircraft powered by solar energy was to remain in Ahmedabad for two days before flying to the holy city of Varanasi on Saturday.
Bertrand Piccard and Andre Boschberg, are taking turns at the controls of the aircraft during their 35,000-kilometer (21,700-mile) journey.
The aircraft's wings are covered by more than 17,000 solar cells that recharge the plane's batteries.
On Monday, Borschberg, who co-founded the Solar impulse company that built the plane, flew the Si2 from Abu dhabi, the capital of United arab emirates, to nearby Oman in the first leg of the epic journey.
Neither pilot will be able to stand in the cockpit while flying but the seat reclines for stretching
if the plane isn't flying level. The SI2 aircraft has a wingspan of 72 meters (236 feet),
spanning larger than a Boeing 747 jumbo jet. At about 2, 300 kilograms (5, 070 pounds), the Si2 weighs about as much as a minivan or mid-sized truck.
