atomhajtású

Atomhajtású refers to a propulsion system that utilizes nuclear reactions to generate thrust. This concept has been explored and developed in various forms, primarily for spacecraft and, theoretically, for terrestrial transportation. The core principle involves harnessing the immense energy released from atomic processes, such as nuclear fission or fusion, to expel a working mass at high velocity.

In the context of space travel, nuclear thermal propulsion is a prominent example. This system uses a nuclear reactor to heat a propellant, typically hydrogen, to extremely high temperatures. The superheated gas is then expelled through a nozzle, generating thrust. This method offers significant advantages in terms of efficiency and specific impulse compared to conventional chemical rockets, allowing for faster transit times for long-duration missions.

Another theoretical application is nuclear pulse propulsion, famously conceptualized in Project Orion. This design envisioned propelling a spacecraft by detonating nuclear bombs behind a pusher plate. While offering immense potential for rapid interstellar travel, the technical and political challenges associated with such a system are substantial.

The development and potential deployment of atomhajtású systems are subject to ongoing research and international regulations due to safety and environmental considerations. The promise of greatly extended range and speed for space exploration continues to drive interest in this advanced propulsion technology.
