He invested £ 60 million in the Skylon space project

The British government recently announced a £ 60m investment for the Skylon space project of the Reaction Engine. The amount of investment approved by the British government is a positive response to the event that the European Aviation Authority (ESA) successfully tested the advanced SABRE engine and the entire amount of capital will be used for open development. wide motor.

Skylon is the design of a space engine using advanced engines called SABRE - considered the biggest breakthrough ever in jet engines.

According to the Gizmag website, the advanced engine referred to here is Synergistic Air-Breathing Rocket Engine (abbreviated as SABRE), an ultrasound static jet engine (scramjet). The engine consumes less propellant fuel due to its versatility, both as a jet engine in an atmospheric environment and as a rocket in a space environment. Therefore, the engine does not need to carry much oxygen to burn liquid hydrogen fuel. This is an idea that has been formed since the 1950s but until now, new technology allows realization.

The limit problem when building an engine is to solve the very high temperatures that the engine emits, especially for engines operating in the highest region of the atmosphere. The engine requires the air flow to be compressed at a pressure of 140 atm, so the air will become very hot, which can melt all kinds of best heat-resistant materials. However, this limit has been solved very well thanks to the most unique point on the SABRE engine which is the pre-cooler "pre-cooler" technology. Before being burned, the inlet air must be suddenly cooled by heat converters. Engineers at Reaction Engine used a closed helium circulatory system consisting of small, impending spiral-shaped tubes containing dense helium gas. The system is designed to quickly cool air flow from 1000 degrees Celsius to -150 degrees Celsius in only 1/100 seconds.

Besides pre-cooler cooling technology , SABRE also has high flexibility when it is capable of operating as a jet or as a rocket, SABRE can help aircraft or missiles reach big speed. five times the speed of sound in the Earth's atmosphere, or 25 times the speed of sound when flying into orbit in outer space. Thanks to its versatile, fuel-efficient operation, the SABRE engine will help Skylon carry out and return flights in one flight without the need for a spare fuel tank or auxiliary propulsion. At the same time, the compact design of the engine will help Skylone space aircraft to be able to store / land at regular runways.
