To achieve MicroPyros objectives, we
propose a three-years program of work based on technological works in
parallel of a theoretical program leading up to the demo phase. The
demo phase will: (1) serve as a guide for the basic research program,
(2) validate technological and designing tools, (3) demonstrate the
potential of mPyros and open it to new fields of application.
The project is built around 4 main work axes related to the project
objectives:
- 1. Technological
developments from the microfabrication towards the assembling and
filling.
To get very precise and reliable
mechanical performance as well as to enhance the integration
scale, we intend to develop advanced technological process to
micromachine the silicon bulk with extreme precision as well as to
assemble each part with high accuracy. The fabrication development
will be performed with the care of a low-cost approach. An
assessment of advanced prototyping equipment (for small volume)
will be considered.
To complete the fabrication development, we plan to implement a
reliable and cost effective technology and develop a specific
equipment to inject the propellant into micronodes. The injection
accuracy, reliability and reproducibility are crucial
parameters.
- 2. Theoretical modelling
and system simulation.
New basic models are necessary to
understand and then predict the processes that occur inside the
chamber during the combustion as well as to calculate the
theoretical performance of the systems. The results of calculation
will serve to build a full system design software with a support
infrastructure.
- 3. Experimental tool
set-up.
The characterization of
"Impulse-bit" micro force or pressure requires an assessment of
the potential technique. Then those best suited will be set up.
The characterisation tools will serve to validate theoretical
models as well as to have expertise tools for further
development.
- 4. Demonstrate the space
application.
We will fabricate a fully
autonomous MicroPyroSystem on the same chip with integrated
command circuitry and power supply. This last task will lead to a
concrete object for a concrete application that will validate the
entire program and will open new perspectives of mPyros. The space
application will be regarded in particular.
