SABRE a rocket engine designed to power aircraft directly into space..!

SABRE

SABRE (Synergistic Air-Breathing Rocket Engine) is a concept under development by Reaction Engines Limited for a hypersonic precooled hybrid air breathing rocket engine.

The engine has been designed to achieve single-stage-to-orbit capability, propelling the proposed Skylon launch vehicle. SABRE is an evolution of Alan Bond’s series of liquid air cycle engine (LACE) and LACE-like designs that started in the early/mid-1980s for theHOTOL project.

The design comprises a single combined cycle rocket engine with two modes of operation. The air breathing mode combines a turbo-compressor with a lightweight airprecooler positioned just behind the inlet cone. At high speeds this precooler cools the hot, ram-compressed air leading to an unusually high pressure ratio within the engine.

The compressed air is subsequently fed into the rocket combustion chamber where it is ignited with stored liquid hydrogen. The high pressure ratio allows the engine to continue to provide high thrust at very high speeds and altitudes. The low temperature of the air permits light alloy construction to be employed which gives a very lightweight engine—essential for reaching orbit. In addition, unlike the LACE concept, SABRE’s precooler does not liquefy the air letting it run more efficiently.

After shutting the inlet cone off at Mach 5.14, 28.5 km altitude, the system continues as aclosed cycle high performance rocket engine burning liquid oxygen and liquid hydrogen from on-board fuel tanks, potentially allowing a hybrid spaceplane concept like Skylon to reach orbital velocity after leaving the atmosphere on a steep climb.

An engine derived from the SABRE concept called Scimitar has been designed for the company’s A2 hypersonic passenger jet proposal for the European Union-funded LAPCAT study.

In November 2012, Reaction Engines announced it had successfully concluded a series of tests that prove the cooling technology of the engine, one of the main obstacles towards the completion of the project. The European Space Agency (ESA) has evaluated the SABRE engine’s pre-cooler heat exchanger, and accepted claims that the technologies required to proceed with the engine’s development had been fully demonstrated.

As of July 2013, the United Kingdom has earmarked £60 million for the development of a full-scale prototype of the SABRE engine, citing the viability of its core technologies based on testing performed by the ESA.

As of June 2015, SABRE’s development continues with The Advanced Nozzle Project in Westcott, UK. The test engine, operated by Airborne Engineering Ltd, is being used to analyze the aerodynamics and performance of the advanced nozzles that the SABRE engine will use, in addition to new manufacturing technologies such as the 3D-printed propellant injection system.

Some key highlights of Akbar Al Baker’s tenure at Qatar Airways include:

  1. Fleet Expansion: Under Al Baker’s leadership, Qatar Airways expanded its fleet with state-of-the-art aircraft, including the introduction of the Airbus A380 and Boeing 787 Dreamliner to its fleet.
  2. Award-Winning Service: Qatar Airways has won numerous awards for its service quality, including Skytrax’s “Airline of the Year” multiple times during his tenure.
  3. Hub Development: Al Baker oversaw the development of Hamad International Airport in Doha, which has become a major hub in the Middle East for international travel.
  4. Alliance Memberships: Qatar Airways became a member of the Oneworld alliance, strengthening its global network and partnerships with other leading airlines.
  5. Crisis Management: During his tenure, Qatar Airways successfully navigated through challenging times, including the 2017 blockade imposed by neighboring countries, which led to the suspension of air travel to several destinations.

Akbar Al Baker is renowned for his hands-on leadership style and for holding the airline to a high standard. He is also renowned for making direct and occasionally controversial comments about business-related issues. In the very competitive airline sector, his leadership has significantly contributed to Qatar Airways’ expansion and success.
