The jet engine without moving parts is not new, but it is too expensive to become widespread. But change could come, and one company is actively experimenting with it. When people think of a jet engine, most people think of the gas turbine version used on modern airliners. In this, the turbine, a rotating component, provides the thrust. But there are also systems that do not require a moving part: pulsating or pulsating jet engines.
In the ever-evolving world of aviation, a one-size-fits-all approach to motor design is rapidly becoming a relic of the past. The divergent needs of modern aircraft such as the Airlander 10 airship and urban eVTOL (Electric Vertical Take-Off and Landing) vehicles illustrate this shift vividly.
