Welcome to AeroMOC’s documentation!

AeroMOC is a open-sourced Method of Characteristic program based on Python. Currently it is 2-D, and it is able to deal with non-isentropic flow. Below is functions available now:

• 2-D non-isentropic flowfield simulation via MOC

• nozzle profile design

  • axisymmetric / 2-D planer maximum thrust nozzle (ideal nozzle)

  • nonsymmetric planer maximum thrust nozzle

  • axisymmetric / 2-D planer minimum length nozzle (Rao nozzle) (issued)

• boundary layer correction

The program is based on references below:

• Three-Dimensional-Nozzle-Design-Code by NASA

• Rice, T., “2D and 3D Method of Characteristic Tools for Complex Nozzle Development,” JHU/APL Report RTDC-TPS-481. 2003.

• 莫建伟., “TBCC排气系统设计方法及流场特性研究”, 南京航天航空大学博士学位论文. 2015.

The program is initially developed by Yunjia Yang (yyj980401@126.com). It is also a option of the assignment of Prof. Yufei Zhang’s (zhangyufei@tsinghua.edu.cn) curriculum “Advanced Aerodynamics”.

The program is open to further development. Please follow the instruction to fork and raise pull request.
