PhD Studentship: Development of methods for simulation of fuel jettison

University of Bristol

The project:

An exciting opportunity exists to develop and test CFD simulation for modelling aircraft fuel jettison.

In the event that a heavily laden aircraft needs to make a landing shortly after departure, the aircraft weight must be brought down to the maximum landing weight (MLW), which is often significantly below the maximum takeoff weight (MTOW). This is achieved by dumping fuel through nozzles located near the trailing edge of the wings, and the safe conduct of this process is an important certification requirement usually proven through flight test. Flight testing is an expensive process, so in order to minimise the hours flown to prove a safe fuel dump capability it is beneficial to support this activity with numerical modelling of the jettison process.

Work will focus on integrating methods that can calculate the trajectory of the exiting fuel alongside existing CFD strategies, and is likely to involve substantial development and verification of new methodologies. International conference travel should be expected.
