Jet propulsion technology hybridized the rocket into reality

The jet-stopping jet technology at supersonic speeds was successfully tested, reducing the flight time from London to New York by one hour.

The next step is to test the technology at Mach 5.5, equivalent to 6,800 km / h, which can shorten the flight time between London and New York to less than an hour. The technology will serve as a jet engine to cross Synergetic Air Breathing Rocket Engine (Saber) rocket , mounted on large planes to transport passengers around the world for several hours and transport cargo to orbit. from UK's Reaction Engines successfully fabricated the pre-cooling unit at a simulation speed of Mach 3,3, equivalent to 4,075km / h, helping to install large supersonic engines on passenger jets. so more feasible. The preliminary cooling unit allows the aircraft to travel at high speeds without contacting the hot air causing the engine to melt. The device has been tested at a simulation speed greater than twice the speed of sound.

Reaction builds the TF2 test facility at the Colorado Aerospace Airport, and uses the General Electric J79 turbojet engine to simulate the conditions that aircraft will experience at supersonic speeds. The company hopes to create a reusable vehicle that combines the fuel economy of jet engines with rocket power and speed.

Oxfordshire-based Reaction said the aircraft could cross London and New York in less than an hour when traveling at full speed. The company also wants to bring passengers and cargo to the universe and return to Earth. Reaction spokesman shared that although it took decades to complete before operating on passenger jets, the new heat exchange technology had many potential applications from aerospace to fast sports. industrial process and process and oil and gas industry.

Preliminary cooling technology is designed to lower the air temperature through an engine from more than 1,000 degrees Celsius to room temperature in 0.05 seconds. To do this, the team developed a heat exchanger to control extremely high temperature air flow. The technology will cool the air in the intake manifold of a high-speed jet turbine engine on supersonic aircraft.

From the takeoff to the speed of Mach 5.5, the Saber engine will load oxygen in the air into the rocket combustion chamber. Here, the engine will fire with liquid hydrogen available. After reaching a high level, it will burn liquid oxygen and liquid hydrogen from the fuel tank. Saber does this by cooling the airflow in less than 0.05 seconds. At low altitudes and velocities, the Saber acts like a jet engine, igniting fuel in a stream of air taken from the atmosphere. At high altitudes and velocities, the Saber will shift to rocket mode, combining fuel with oxygen inside.
