Rolls-Royce's Most Notable Engines That Changed Long-Haul Flying Forever

In the late 1950s, intercontinental air travel was a noisy, expensive, and fuel-thirsty endeavor. Early transatlantic jetliners used pure turbojet engines that forced every cubic foot of air through a white-hot combustion core, consuming massive quantities of kerosene while screaming across the skies at maximum power. The fundamental challenge of long-haul aviation was clear: to make global flight economically accessible, propulsion systems needed to generate far greater thrust and burn significantly less fuel per mile.
