Rolls-Royce was initially founded in 1906 by Charles Rolls and Henry Royce. The company initially focused on the development of luxury automobiles, but as the First World War began, Rolls and Royce pivoted the company to focus on a new endeavor, aircraft engines. In 1914, as the war began, Rolls-Royce responded to a call from the British government seeking a dependable power plant for its expanding fleet of military aircraft.

This led to the development of the company’s first aircraft engine, initially known as the Eagle. This engine was a 12-cylinder liquid-cooled piston engine. The Eagle was an instant success in the market, powering several important military aircraft, such as the Handley Page bomber and the Vickers Vimy. The success of the Eagle led to the company’s reputation as a major player in the rapidly developing aviation world.

Rolls-Royce built on the success of the Eagle with the introduction of its most famous engine of the era, known as the Merlin. This engine, which was a liquid-cooled V-12 four-stroke piston engine, powered iconic aircraft like the Supermarine Spitfire, the Hawker Hurricane, and the Avro Lancaster. Nearly 150,000 total Merlin engines were built, beginning in the early 1930s.

The success of the Merlin engine, alongside other popular piston engines, brought Rolls-Royce into the 1940s. By the end of the decade, the jet age was beginning to arrive. Rolls-Royce followed this trend with the introduction of its first turbojet engine, the Welland. This was possible after the company acquired the jet engine development project from Power Jets Ltd, a company founded by Frank Whittle. This aircraft engine marked the start of a new era for aircraft propulsion. Overall, according to Rolls-Royce, the Welland had the following performance specifications:

The Welland powered the Gloster Meteor, the Royal Air Force’s first jet fighter, which entered service during the final years of World War II. However, after the success of the Welland, Rolls-Royce continued to rapidly develop its jet engine technology. This includes the development of iconic engines, such as the Derwent engine, which would power later Gloster Meteors.

By the early 1950s, Rolls-Royce began introducing engines with axial-flow compressors, which allowed for higher efficiency and thrust than older engines. This led to the development of the Avon, which would later become one of the company’s most successful engines, powering both military and civil aircraft. In the 1960s, Rolls-Royce introduced its first production turbofan engine, the Conway. This legendary engine powered the Boeing 707 and Douglas DC-8 in the commercial industry.

Additionally, in the early 1970s, Rolls-Royce introduced the groundbreaking RB211 series, which utilized a unique three-spool design. The RB211 was a modern turbofan engine which, although it is no longer produced, continues to power a large portion of commercial aircraft around the world. The RB211 was also the foundation for the widely used Trent family of turbofan engines.

Rolls-Royce has remained a major player in the commercial aviation market. The company’s flagship engine, the Trent XWB, was first introduced in the early 2010s. This powerful engine powers the Airbus A350 family, one of the most advanced widebody airliners. The Trent 1000, another efficient engine in the Trent family, also powers the Boeing 787 Dreamliner, another widebody aircraft focused on long-haul operations.

Beyond the Trent family, Rolls-Royce also produces engines for regional airliners and private jets. Specifically, the Rolls-Royce Pearl and Rolls-Royce BR700 are widely utilized by popular aircraft manufacturers. The company continues to invest heavily in research and development, which reflects the company’s commitment to supporting the entirety of the aviation industry.
