The simple, low-cost, and reliable way for the United Kingdom to develop a reusable space shuttle into space is critical to the development of the global space market. It is estimated that its value worldwide exceeds 150 billion US dollars. Today, British aerospace engineering experts are developing a reusable space shuttle-Skylon, which can carry 12 tons, can enter orbit from a conventional aircraft runway, and can return to the ground on the same runway, all in just 10 years Can become a reality. The project is led by the British company REL, which is part of a multi-million pound public and private sector joint project and has received funding from the European Space Agency (ESA) of 1 million euros. This technology, developed by a group of European experts including scholars from the Department of Aeronautical Engineering at the University of Bristol, uses Sabre aspirated rocket engines to power the Skylon space shuttle. The Sabre is a special hybrid engine. When it is in the atmosphere, it can inhale air and operate like a jet engine; when it enters space, it turns into a rocket engine. In suction mode, before being compressed, the air is first cooled by a heat exchanger pre-cooling device and burned with hydrogen fuel to provide power for the rocket engine. In rocket mode, hydrogen will burn with liquid oxygen. Alan Bond, the head of REL, believes that the ultimate goal of this project is to "use a truly reusable space shuttle that can take off at an airport and go directly into space, launch a payload satellite and return to Earth safely and automatically." He added: "The cost of a traditional single-use rocket per launch is more than $ 100 million, which has dragged down the development of the space market. REL has planned and researched Skylon tools for many years and its unique Sabre aspirated engine. It means that we are in a good position to achieve this goal. Skylon can reduce the cost of entering space to 1/10 of the original. "The demonstration project will focus on three key areas of the engine. The first area is the responsibility of REL, which focuses on a revolutionary pre-cooling device that cools air as it enters the engine. The second key area is the cooling of the combustion chamber. The combustion chamber is where the propellant mixes and burns and produces water vapor at about 3000 degrees Celsius. Sabre engines use air or liquid oxygen as a coolant, which is an important and unusual design feature, because most rocket engines use hydrogen fuel for cooling. The third area is to explore advanced exhaust nozzles that can adapt to the surrounding atmospheric pressure. The goal of this demonstration project is to eliminate the obvious technical worries of all Sabre engines. This will pave the way for the entire engine development project as part of the Skylon development project. Lord Drayson, Secretary of State for Science and Innovation, said: "This is an example of technology that can bring exciting results to the future development of space and shock the world. REL, Bristol University and the European Space Agency have successfully reached a cooperation agreement. An excellent thing, I look forward to the project.
