Rolls Royce Avon
One of the first highly successful axial-flow turbojets.
Powered aircraft like the English Electric Canberra and later versions of the de Havilland Comet. It helped move jet engines from experimental to reliable mainstream powerplants.
Pratt & Whitney J57/JT3C
One of the first highly successful axial-flow turbojets.
Powered aircraft like the English Electric Canberra and later versions of the de Havilland Comet. It helped move jet engines from experimental to reliable mainstream powerplants.
Mikulin AM-3
A high-thrust Soviet turbojet derived from military bomber engines. It enabled the Tu-104 to become one of the first operational jet airliners in the world. Built for power and durability, it reflected the USSR’s rapid entry into commercial jet aviation.
Rolls-Royce Conway
The world’s first production turbofan engine, introducing bypass airflow into commercial service. By routing some air around the core, it reduced noise and improved fuel efficiency compared to pure turbojets. The Conway marked the technological turning point from the first Jet Age to the turbofan era.
Pratt & Whitney JT8D
A low-bypass turbofan designed for short- and medium-haul jetliners. It powered aircraft like the Boeing 727 and Douglas DC-9, bringing jet travel to regional and high-frequency routes. The JT8D became one of the most widely produced engines of its time and defined 1960s narrow-body aviation.
