Mae Dr Shaw yn Uwch-ddarlithydd yn y portffolio Awyrofod ym Mhrifysgol Abertawe ac mae’n rhan o’r grŵp Peirianneg Awyrofod a Strwythurau yng Nghanolfan Peirianneg Gyfrifiadol Zienkiewicz. Mae’n addysgu cyrsiau mewn dadansoddi strwythurol a dylunio awyrennau.

Mae diddordebau ymchwil Dr Shaw yn cynnwys dirgryniad strwythurol a strwythurau addasol. Ym maes dirgryniad strwythurol, mae ei ymchwil yn ymwneud yn bennaf ag aflinoledd, sy’n cyflwyno rhai ffenomena tra diddorol a chain, gan gynnwys ymatebion anhrefnus a lled-gyfnodol. Mae diwydiant yn ymdrin â dirgryniad mewn modd llinol yn bennaf, felly mae’n colli ffiseg hanfodol a gall hyn roi rhagfynegiadau gwael. Drwy ddulliau arbrofol a dadansoddol, y nod yw cyflawni offer a fydd yn caniatáu modelu aflinoldeb yn effeithlon a’i ddefnyddio mwn strwythurau statig a pheirianwaith sy’n cylchdroi.

Mae awyrennau addasol yn gallu addasu eu siâp allanol i ymateb i newid mewn gofynion hedfan ac felly wella effeithlonrwydd cyffredinol y genhadaeth. Fodd bynnag, maent yn peri heriau sylweddol i strwythurau awyrennau. Ar hyn o bryd, mae Dr Shaw yn ymchwilydd ar y rhaglen H2020, Shape Adaptive Blades for Rotorcraft Efficiency (SABRE) sy’n cymhwyso cysyniadau addasu i lafnau rotorau hofrennydd.

EG-2002 Aerospace Structures

This module develops the structural concepts studied in EG166 `Engineering Mechanics¿ and EG120 `Strength of Materials¿, with an emphasis on aerospace structures.
EG-2002TX Aerospace Structures (Texas)

This TB2 module is only to be taken by students who have been on the Texas exchange programme. It is taught in the same sessions as EG2002. The module develops the fundamental skills of an aerospace structural engineer, and also introduces a range of advanced analysis techniques.
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, structures, 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 their peers and supervisors. 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 to include ethics, operational and EDI aspects. Group planning statement will include a pass/fail element for team ethics and EDI considerations. 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.
