British engineers completed their new high-speed spacecraft test



Hypersonic elevation across the Atlantic advanced a step closer after scientists successfully tested technology to stop the melting of jet engines at speeds up to 25 times the speed of sound.

Researchers at Reaction Engines have been able to make a "pre-cooler" work at an simulated speed of 3.3 mkg or 2 500 mph (4,023 mph) – which means that large-scale hypersonic engines that can be installed on passenger aircraft, a step closer to realization. Their experimental synergistic airborne rocket engine (Saber) is designed to be installed on large aircraft for the transportation of passengers around the world for several hours and delivery of goods to orbit less.

"Pre-cooler", which allows the aircraft to move at high speed without hot air inflow, and forcing the engine to melt, was tested on at simulated speeds more than three times the speed of sound.

The next test stage will allow checking technology at Mach 5.5 (4.200 mph), and one day may result in flights between London and New York that take less than an hour.

  British engineers completed checking out their new high-speed

British engineers completed their new high-speed "space plane" test, which they could fly 25 times the speed of sound (max 25). Reaction engines have tested the technology of "pre-cooling" – which allows planes to move faster than ever.

The reaction built a test facility on the ground in Colorado and used the General Electric J79 turbojet engine to repeat the conditions that the car will feel at hypersonic speeds.

The company hopes to create a reusable vehicle that combines the efficiency of a jet engine fuel with the power and speed of the rocket.

A Oxfordshire based response suggests that aircraft can travel from New York to London in less than an hour when it operates at the proposed maximum speed.

The company also wants to take people and useful cargo into space and

A representative of reaction machines told MailOnline that even though this technology has been used for decades on passenger aircraft, the technology can be used in more direct applications. The technology of the heat exchanger has a wide range of potential commercial applications and the ability to revolutionize the approach to thermal management in various industries; from aerospace to motorsport, industrial processes and the oil and gas industry.

The breakthrough test was carried out at the newly created Colorado Air and Space Port TF2 Test Center

. The UK around the engine cycle concept to allow access to space and hypersonic air-breathing flight from the starting start. The pre-cooling technology is designed to reduce the temperature of the air entering the engine from more than 1000 ° C (1832 ° F) to room temperature for one twenty second.

The team developed a heat exchanger for controlling very high temperature air flows.

  Reaction Engines has tested the "pre-cooling" technology, which allows aircraft to move faster than ever. The Synergetic Air Breathing - Saber pilot rocket engine designed to attract space planes to orbit and receive airplanes worldwide in just a few hours.

and ultimately will form the basis for the Saber engine for inexpensive, recurrent access to space.

The goal is to turn this technology into its Saber engine, which would work as an "air breathing air engine". This would be much less oxidizing fuel than a conventional missile, which would make it much easier.

From take-off to 5.5 Mach (5.5 times the speed of sound), it takes oxygen from the atmosphere that will be fed into the rocket combustion chamber.

  During tests, at modeling speeds of 3.3 Mach, or more than three times the speed of sound. In order to repeat the conditions that it will experience at hypersonic speeds, Reaction built a test facility on the ground in Colorado and used the General Electric J79 turbojet engine.

Here it will be ignited with accumulated liquid hydrogen and then switch to high altitude, burning liquid oxygen and liquid hydrogen. from onboard fuel tanks.

Mark Thomas, executive director of Reaction Engines, told The Times: "If you can pull it out, it's a game change. It strikes ordinary rocket engines.

He did this by successfully extinguishing a gas flow of 420 ° C (788 ° F) in less than 1/20 seconds.

At low altitude and low speeds, he behaves like a jet, burning his fuel in the air flow drew from the atmosphere.

At high speeds and at high altitudes, he would switch to full rocket mode, combining fuel with oxygen entering the inside.

  They predict it will be a capable airplane that could travel the distance between New York and London in less than an hour. They also want to take people or cargo to space and return to Earth

HOW TO DO REACTIVITY ENGINES & # 39; & # 39; SABER & # 39; & # 39; It combines both jet and rocket technology.

The Saber engine works by combustion of atmospheric air in combustion chambers.

At the moment, the missiles should carry liquid oxygen and liquid hydrogen to feed them, and the cost of transporting this heavy fuel is expensive.

The new engine creates its liquid oxygen by cooling the air entering the engine from 1000 ° C to minus 150 ° C in a hundredth of a second – six times faster than the eye of the eye – without [19659002] This new class of aerospace engine is designed to allow planes to operate from shutdown to runway at speeds in excess of about ten times the speed of sound in the atmosphere.

Then he can switch to flight mode of the rocket, allowing space flight at speeds up to orbital speed, which is equivalent to 25 times the speed of sound.
