Clustering of the porous
tungsten crown emitter

Achievable either on sub-systems level or on crown level.

The flexible design of the ENPULSION NANO allows for an easy clustering to various configurations. This introduces an inherent redundancy of the system, as each module is completely independent. The configuration of seven modules fits into a 15-inch (38 cm) separation ring, which allows for 2.4 mN of continuous thrust at 200 W and a total impulse of more than 35 kNs with 1.75 kg of propellant.

Clustering Individual ENPULSION Nano

Clustering individual modules is an advantage for spacecrafts that are smaller than ~150kg.

Clustering Porous Tungsten Crown Emitter

The ENPULSION MICRO R³ is engineered in a modularity approach, with units clustering easily together to form building blocks that can be arranged for various mission profiles

A highly versatile

The flexible architecture of the ENPULSION NANO allows for a large number of possible mission advantages.

Attitude Control Capabilities

With multiple modules, one can have the opportunity to perform accurate attitude control.

Orbit Life Extension Possibilites

Mission extension ranging from weeks to years, especially in low altitude orbits with increased resolution for earth remote sensing such as imaging applications.

Formation flying and constellation control

Controlling inter-satellite distance in the orbital plane.

Orbit raising made flexible for each launch

Gain flexibility in the choice of a suitable launch opportunity, including a cheap ISS deployment.

Highly efficient deorbiting

Efficiently deorbit a small satellite from a higher orbit to comply with international Space-Debris Regulations or perform an EOL maneuver putting it in a graveyard orbit.

Safe and Inert systems compliant

The thruster uses liquid metal as the propellant. The propellant is in its solid state at room temperature. Avoiding any liquid and reactive propellants as well as pressurized tanks, significantly simplifies handling, integration, and launch procedures.
