Propulsion System Design
At Micro Aerospace Solutions, we specialize in propulsion design, development and testing. We are involved in a variety of systems and propellants such as monoprops, bi-props, solid, and hybrids. We can also do complete propulsion system development including engine design, tanks and valve system intrgeation. Below is example of one of our systems integrating propulsion, attitude detection and GPS sensors into one module.
Complete Small Satellite Propulsion Modules
We have demonstrated a complete thruster system that fits well within the body of a 10 cm cube cubesat configuration. This system uses a positive expulsion blowdown system to feed hydrogen peroxide to four thrusters around the base of the vehicle. The image below shows the system.
Cubesat Thruster Module With Two Inch Tank, Micro-Solenoid Valves and Thrusters
This system could be adapted to other configurations such as spacecraft with larger internal volumes and requirements for more thrusters and a larger propellant need. Below is a mass table for this system configuration.
| Components | Mass (ea) (grams) | Quantity | Total Mass |
|---|---|---|---|
| Tank | 60 | 1 | 60 |
| Thruster With Valve | 4.9 | 4 | 19.6 |
| Manifold | 3.6 | 1 | 3.6 |
| Tees | 2.1 | 1 | 2.1 |
| Stainless Connectors | 1.5 | 2 | 3 |
| Miscellaneous Tubing | 2 | 1 | 2 |
| Propellant (H2O2, mL) | 1.45 | 40 | 58 |
| Total | 148.3 Grams |
Nanosat Thruster Module Mass Summary
Below is a CAD drawing of a Cubesat with four Microthrusters.
Tank Design and Testing
We can assist in designing and integrating off-the-shelf tank systems into a variety of propulsion system designs. These include developing multi-structural elements for cubesats that use tanks as part of the structural element.
Triad Thruster Structural Design
Thrusters sometimes have to be oriented in triads or other multiple configurations. Our engineers can work with your team to design triads for a variety of spacecraft configurations. We also have pluggable thruster modules that can be readily integrated into rapid response spacecraft systems.
Integration Design
Whether you require a complete propulsion design or a simple thruster assembly we can provide custom solutions to integrate into your specific application. Our system designs and concepts are flexible and adaptable to a variety of configurations. We have built, tested and flew hydrogen peroxide systems, hydrazine systems, bi-prop hydrogen peroxide/kerosene systems and others from 50 milli-Newtons of thrust to over 10,000 Newtons
Valve Systems
We have experience recommending a variety of valve systems depending upon customer requirements and applications. Our thrusters are not tied to a single valve design which allows for flexibility.
