Research Studentship in Numerical Study of Plumes and Booster Stage Separation in HCMs

4-year D.Phil. studentship 

Project: Numerical study of plumes and booster stage separation in HCMs

Supervisors: Prof Luca Di Mare & Prof Matthew McGilvray

This project will conduct research into base flow and plume interaction during the stage separation phase in the flight of a hypersonic vehicle launcher. At the beginning of the separation manoeuvre, a plume induced separation appears on the leading vehicle, while the trailing vehicle is surrounded by the flow generated by the plume, and a generally asymmetric shock surface. The trajectories of both the leading and trailing vehicle are affected by the flow fields.

Objectives

1. The objectives of the proposed study are as follows:
2. Conduct experiments in the Oxford hypersonic wind tunnels at fixed configurations to obtain reference data for a preliminary numerical campaign
3. Conduct a preliminary campaign validating external aerodynamic predictions at mission-relevant conditions in presence of plumes, gaps and misaligned bodies in static configurations
4. Conduct wind tunnel tests with separating bodies using pyrotechnic devices to achieve separation and free flight. Image tracking techniques and onboard instrumentation will be used to obtain quantitative trajectory data.
5. Conduct a matching numerical campaign aimed at reproducing the observed trajectories
6. Generate a database of aerodynamic force and moment proximity data and demonstrate their use in a flight dynamics code to reproduce the experimental data obtained in the campaigns at points 1) and 3).
