|Pintle injector designer is a beta version of a small throttleable liquid rocket engine design software. It is currently being beta tested and will be available free of cost within 3 months. Currently,this software is used for Face Shut Off type pintle injector, final product will be capable of providing design data for Slit type as well. Future versions will have results of calculation for dimensions of the injectors in CAD software recognizable format.|
Calculating the mass flow rates of a rocket engine is a time consuming process. Pintle injector design software eases the calculation process. This software reduces mass flow rate and discharge area calculation for a liquid fueld combustion chamber to just 5 minutes.
You can use the current version of pintle injector design software to calculate the mass flow rate and discharge are needed for a pintle injector to be used in liquid rocket engines.
The resulting data is printed to a file called "myfile.txt".
How to use the pintle injector design software to calculate the mass flow rate and discharge ?
|Pintle injector Design software- entering inputs such as Thrust of rocket engine, Mixture ratio etc|
- STEP 13- Enter the discharge co-efficients of fuel and oxidizer exits. They can be reasonably approximated to 0.7 or exact value can be found after the fabrication.
- STEP 14- Enter the pressure drop of fuel and oxidizer in the next. A good approximation is 20% drop from the combustion chamber pressure as noted from SP-125 NASA rocket design book.
- STEP 15- Enter the Density of fuel and oxidizer in kg/metre cube.

Special thanks to Albin Shaji (Computer Science Department-Karunya University) for writing the code for this software.
|The full data required for the pintle injector will be written to "myfile.txt" file created on the same folder where this software is installed.|
