Realistic Designs AG Atomic Rockets
A new technology, the Fission Fragment Rocket Engine (FFRE), requires small amounts of readily available, energy dense, long lasting fuel, significant thrust at specific impulse of a million seconds, and increases safety by charging the reactor after arrival in LEO.

Fission Fragment Rocket Engine (FFRE). This NIAC study addresses the FFRE as well as its impact on Exploration Spacecraft design and operation. It uses the common physics of the relativistic speed of fission fragments to produce thrust. It radiatively cools the fissioning dusty
Fission Fragment Nuclear Propulsion Variants and Technical Details
The fission core is located within the bore of an electromagnet and external neutron moderator material. The low-density aerogel allows for radiative cooling of fuel particles while minimizing collisional losses with the fission fragments, leading to a more efficient use of fissile fuel in producing thrust compared to previous concepts.

Fission fragment rocket Alchetron, the free social encyclopedia
From FY11 through FY14, the NASA Institute for Advanced Concepts studied the Fission Fragment Rocket Engine (FFRE). ( Werka et al., 2012; Chapline, 1988; Chapline et al., 1988; Chapline and Matsuda, 1991 ). The FFRE would directly convert the momentum of fission fragments into spacecraft momentum at extremely high specific impulse ( ISP ).
Fission Fragment Rocket Engine Thrust Velocity at 1.7 of light speed
What Is a Fission Fragment Rocket Engine? FFREs are not a new concept in themselves, but many have massive technical hurdles to overcome before they can be considered useful. Their advantages.

Fission Fragment Rocket Engine Thrust Velocity at 1.7 of light speed
Similar to how the fission-fragment rocket produces thrust, a fission fragment reactor is a nuclear reactor that generates electricity by decelerating an ion beam of fission byproducts instead of using nuclear reactions to generate heat.
Fission Fragment Nuclear Propulsion Variants and Technical Details
The NASA Office of Chief Technologist has funded from FY11 through FY14 successive studies of the physics, design, and spacecraft integration of a Fission Fragment Rocket Engine (FFRE) that directly converts the momentum of fission fragments continuously into spacecraft momentum at a theoretical specific impulse above one million seconds. While others have promised future propulsion advances.
Fission Fragment Rocket Engine Concept Puts 100 Light Years
The FFRE geniuses of Grassmere Dynamics who created this engine for the first time spent many hours, including their own time, in the complex effort to create, analyze, design, estimate performance and figure out how a real engine could be developed and tested.

Introduction: The Dusty Plasma Fission Fragment Rocket Engine DPFFRE,[1],[2] is a promising solution to the difficulty of using the highest energy density fuel in the vacuum of space, where ordinary planetary reac-tors would overheat and melt. Surprisingly, the limits on space nuclear propulsion are not feasibility or safety related, but thermal.
Fission fragment rocket
Current proposed designs for Fission Fragment Rocket Engines are prohibitively massive, have significant thermal constraints, or require implementing complex designs, such as dusty plasma levitation, which limits the near-term viability.
Juno New Origins Afterburner Fission Fragment Rocket Engine
The fission fragment rocket (FFR) is a theoretical engine design that uses the products of nuclear fission (" fission fragments ") to generate thrust. These fission fragments cannot normally escape from the fuel, but in an FFR this is designed to be not only possible but likely. A number of different designs have been proposed, but perhaps.
Fission Fragment Nuclear Propulsion Variants and Technical Details
The fission sail is a type of spacecraft propulsion proposed by Robert Forward that uses fission fragments to propel a large solar sail -like craft. It is similar in concept to the fission-fragment rocket in that the fission by-products are directly harnessed as working mass, and differs primarily in the way that the fragments are used for thrust.
Fission Fragment Rocket Engine Thrust Velocity at 1.7 of light speed
The fission-fragment rocket is a rocket engine design that directly harnesses hot nuclear fission products for thrust, as opposed to using a separate fluid as working mass. The design can, in theory, produce very high specific impulse while still being well within the abilities of current technologies.
