Objective: To perform CFD analysis of the preliminary design of the Firehorn II Launch Vhicle in order to better understand the flight loads it will experience.
Project: Firehorn
Work Package Manager: Michaël Fuser (Firehorn FD SE)
Start: Start of fall 24 semester (09/09/2024)
End: Friday of the second week folllowing the end of the fall semester (03/01/2025)
- Fluid Domain Creation
Create the quarter fluid domain surrounding the Rocket.
- Initial mesh creation
Create a first version of the mesh.
- Initial Setup Creation
Create the setup used in Fluent (BCs, models, convergence, ...).
- Mesh correction
After having run the simulation for the first time, go back to the meshing stage and perform necessary corrections to get acceptable results.
- Mesh and domain study
Perform a mesh and domain study, and rerun previous simulations if previous results were not mesh or domain independent.
- Postprocessing activities
Perform postprocessing activities (quantitative and qualitative verification, extraction of required results).

- In-depth analysis of the dynamic flight loads experienced during flight
Get a deeper understanding of the types of loads encountered during flight and the way to model them using CFD.
- Simulation with the engine plume interaction
Rerun a previous simulation, but this time include the engine combustion chamber in the fluid domain. This will likely not change the measured loads, but could give some nice images for external communication.
- Transient simulation
Rerun a previous simulation but this time in the transient regime. This will likely not change the measured loads, but could give some nice animations for external communication.
- LES simulation
Rerun a previous simulation but this timeusing LES. This will likely not change the measured loads, but could give some nice animations for external communication.
- Image generation using ParaView
Use ParaView to generate quality images from the previously generated simulation data, which could then be used for external communication.
- Report Writing (W15)
Write a report to be handed to the professor and graded.
- Documentation Writing (W15)
Write the required documentation as described in the end of this document.
- Launch Vehicle Dimensions
The dimensions of the Launch Vehicle will be provided by the supervising SE and are necessary for the creation of the fluid domain.
- Variables for the Boundary and Operating conditions
Variables such as the air velocity, the air pressure and the air tempaerature needed to be used for the simulation boundary conditions will be provided by the supervising SE.
- Semester Project on FH30 CFD
There might be some slight interfaces with the other semester project of the CFD analysis of the FH30 Launch Vehicle.
- Simulation data
All data of the final versions of the CFD simulations must be stored on the ERT drive.
- Summary of flight loads
A summary of the main flight thermomecanical loads (forces on fins, bending moment, temperature distribution, ...) encountered during flight must be provided at the end of the project so that it can be used by the structural engineers.
- Semester project report
A report describing the unfolding of the semester project. (EPFL Requirement)
- CFD Analysis Report
Wiki document to document the CFD simulations.
- Launch vehicle sizing activities
This project is only about the analysis of the already provided preliminary sizing of the Firehorn II Launch Vehicle. The sizing of the vehicle and the dimensioning of the aerodynamical parts of the LV will be done by other members.
