Pursuing D-He3 fusion for its off-grid possibilities such as defence, transport and space exploration.
The Direct Fusion Drive (DFD) is a compact nuclear fusion engine which could provide both thrust and electrical power for spaceships. This technology opens unprecedented possibilities to explore the solar system in a limited amount of time and with a very high payload to propellant masses ratio.
Since DFD provides power as well as propulsion in one integrated device, it would also provide as much as 2 MW of power to the payloads upon arrival. Designers think that this technology can radically expand the science capability of planetary missions.
The Direct Fusion Drive is a revolutionary steady state fusion propulsion concept, based on a compact fusion reactor. It will provide power of the order of units of MW, providing both thrust of the order of 10−101N with specific impulses between 103− 105s and auxiliary power to the space system
- Specific Impulse (s) **103 – 105 **
- Thrust (N) 10 – 101
- Propellant D – 3He
- Exhaust Speeds (km/s) 110 – 350
- Dimensions (m) 9.8 x 3.5 x 3.5
Pulsar Fusion is presently committed to the construction of its initial prototype static DFD engine. After completing a State of the Art (SoA) assessment on DFD heating technology in 2021, further analysis was carried out by a panel of experts to finally make an informed decision on an initial design point for the system.
