This project “Manipulation of Flow Characteristics using Laser Energy Deposition” is supported by European Commission.
Objective of this project
Travelling at high speeds entails overcoming adverse effects, such as regions of high heat transfer and surface pressures, unsteady shock waves, fluid-structure interactions, together with the requirement of drag reduction. One method of flow and flight control is energy addition. It is the objective of the study to utilise this technique for the development of:
- Mitigation schemes for the avoidance or modification of localised regions of high heat transfer and surface pressure of high-speed vehicles.
- Methods for controlling local flowfield characteristics and the location of shocks e.g., in engine inlets, and wing-fuselage junctions.
The research program combines both branches of research, namely, experimental and numerical. It aims to advance the frontiers of supersonic and hypersonic aerothermodynamics and propulsion and it will firmly establish a UK/European lead in research on laser energy systems for flight and flow control of high-speed vehicles.
