Office hour for October-December 2019: Tuesdays 2pm

My interests include rotordynamics, particularly of systems undergoing rotor stator contact, and methods to model and characterise nonlinear structural vibration both analytically and experimentally. I am also very interested in morphing aircraft, in particular morphing of helicopter rotor blades through the H2020 project Shape Adaptive Blades for Rotorcraft Efficiency (SABRE).

I am the Year Coordinator for the 1st year of the aerospace engineering course at Swansea.

Teaching

  • EG-268 Experimental Studies - Mechanical

    The course introduces the students to experimental studies in a wide range of subjects. There are four individual experiments (HEAT/JET/STRESS/VIBRATION) Each experiment is self contained and the student will be assessed via either: ¿ A lab report which will have a set of experiment specific questions to answer. ¿ An online Blackboard assessment. All students work in groups and carry out four experiments, however the assessments are all individually submitted. The students keep a log-book of the experimental observations and results, which is used for reference for the technical report from each experiment written-up in the week after the experiment.

  • EGA227 Structural Mechanics for Aerospace Engineers

    This module develops the structural concepts studied in EG166 `Engineering Mechanics¿ and EG120 `Strength of Materials¿, with an emphasis on aerospace structures. The concepts of residual stress, constitutive laws and compatibility are introduced, as are virtual work and energy theorems, which lead to the highly versatile unit load method. This enables students to obtain internal loads, reactions and deflections for complex and statically indeterminate structures.

  • EGA302A Aerospace Engineering Design 3

    The module is a group design project for year 3 aerospace engineering students. Students are required to design an aerospace vehicle from an initial set of mission requirements and constraints through concept design to detailed design and flight testing. It requires students to draw on knowledge from a range of modules across the aerospace engineering course. Each student will specialise in one of six areas: aerodynamics, structure, materials & propulsion, weight& performance, control systems or dynamics & stability. Groups will be required to submit a series of group design reports at each stage in the design process as well as deliver presentations to the rest of the class. Each student will also take a turn acting as chief engineer and a reflective essay is required after the student's time as the chief engineer. By the end of the module students should have an understanding of the process and complexities involved in designing an aerospace vehicle from scratch and appreciate the multi-disciplinary nature of this task. Note that since this module is, in part, explicitly assessing students' ability to work effectively within a team environment the group submissions and peer review components of assessment cannot be excluded for extenuating circumstances.
