Reaction Engines has proved its revolutionary engine technologies to withstand high hypersonic speeds, marking a significant breakthrough in hypersonic flight production and for planes, which could carry travelers from earth to around the world one day.
Oxfordshire has demonstrated the feasibility of its method of precooling in conditions equal to a speed of Mach 5, creating a new type of hybrid engine known as Sabre incorporating conventional jet and rocket technology.
The air that entered a jet engine would reach 1,000 ° C at that point, adequate that components would be badly affected. In less than a 20th of a second, the precooler of the reaction lowers the air to minus 150 degrees C.
The project at the Reaction test site in Colorado completed two weeks ago, marked the first world test and paved the way for the hypersonic flight, Chief Executive Mark Thomas said.
“This is the first time that cooling technology has been taken at these stages and the promise for a high-speed precooled jet engine has really been plausible,” he said. “It’s rare.” Rocket engine technology was the basis of the previous hypersonic aircraft, said Mr. Thomas.
The Mach 5 is more than twice as high as Concorde’s cruise speed and is almost 50% higher than the SR-71 Blackbird, the world’s most powered jet engine. An airplane could cross the Atlantic in two hours at that pace.
The Sabre motor was planned as part of a Skyline model for a spacecraft.
Sabre uses jet engine technology which effectively “respires” air to 20% of the orbit journey before switching to rocket mode to finish its journey. Since then, the company has focused on the propulsion and pre-cooling systems that it claims to be even larger. The reaction should begin building and testing a demo engine next year
The coolers he said to use to increase the speed and fuel consumption of current jet engines, would be commercialized by Mr. Thomas. He also said that the precooler will consider applications in the automobile and energy industries. He added that next year he was hoping to start earning his first export revenue.
The positive cooling test has been extremely significant in the aerospace industry, said Mark Scully, technical chief for advanced systems and propulsion, Aerospace Technical Institute.
“Major focus areas of manufacturers are the control that aircraft engines withstand extraordinarily high temperatures during service, and this is even more critical for engines that operate at very high speed,” he said. “Not only will this deliver a world-class capability for the air-breathing rocket engine but it could also enable future jet engine designs with even greater efficiency and reduced environmental impact.
In order to counter the rising commercial space industry, the UK Government emphasized the value of technological Reaction to its own ambitions.
“The Sabre engine is one of the most innovative technology ventures in Britain that will forever transform our way of launching satellites and of flying around the globe,” Science Minister Chris Skidmore said.
The Reaction Engines were developed in 1989 in order to fulfill their visions of space exploration, in the name of Alan Bond, Richard Varvill, and later John Scott-Scott, known as the three rocketers. Such three were able to address the difficulties posed with the pre-cooling concept by long-time experts at Nasa and Rolls-Royce.
The positive test is considered to be a “momentous milestone” in the production of the Sabre engine by Mr Varvill, Reaction’s co-founder and chief technical officer. Sabre has “the ability to revolutionize both space and high-speed flight exposure by moving aircraft at five times the sound level.
It takes us closer to achieving our goal of developing a first air respirator capable of accelerating from 0 to Mach 5. “The cumulative sum of GBP 100 m from public and private donors, including the Boeing, Rolls-Royce and BAE Systems has been collected over the last three years.
