RESEARCH

Jerome's research is in Multidisciplinary Aeronautical Design.

He is a founder and the Co-ordinator of the Integrated Design Consortium (IDC), a group which principally focusses on aeronautical design; he has personally worked closely with Rolls-Royce for several years in civil jet engine conceptual design. The research programme of the IDC is currently supported by the UK Engineering and Physical Sciences Research Council, the Technology Strategy Board, Rolls-Royce and the US Office of Naval Research.

Jerome's specific research interests can be grouped into three discrete, but highly coupled and mutually reinforcing, areas:
  • AERODYNAMIC DESIGN
  • AEROTHERMAL DESIGN
  • COMPLEX SYSTEM INTEGRATION

TEACHING

Lecture courses and projects recently, currently or soon to be taught by course year - students please refer to current timetables for details.

First Year:
An Introduction to the Aerodynamic Design of Aircraft
This lecture forms part of the set of introductory lectures given in the Department of Engineering just before the formal start of the first year. It covers the basic concepts of heavier-than-air flight and follows the chronological development of aerodynamics and aircraft design.

Second Year:
Linear Algebra in Paper 7 - Mathematical Methods
This lecture course introduces Part I Engineers to a range of mathematical techniques for handling vectors and matrices including Gaussian elimination, LU factorisation, Gram-Schmidt orthogonalization and Singular Value Decomposition. The practical relevance of the methods is illustrated by application to numerous engineering examples and current research in CUED ranging from neonatal ultrasound imaging through improving mobile phones to designing airliners that can more safely fly in icing conditions.

Third Year:
Two-dimensional compressible flow in Module 3A3 - Fluid Mechanics II
This course starts with the development of linearised potential flow equations as pioneered in the 1920s with the contemporary rapid increase in attainable flight speeds by aircraft such as those competing for the Schneider Trophy. The method of characteristics for simple 2D flows and flows involving reflection / cancellation is then introduced. The origin of oblique shock waves and their reflection is then applied to practical flows via shock-expansion theory, linearised method of characteristics and linearised potential theory in the design of supersonic airfoil sections and variable geometry ramp intakes as seen on aircraft such as Concorde, Tornado and F-15.

Light Aircraft Design Project GC2
This is a group project involving the aerodynamic, mechanical and structural design of a light aircraft. Its principal aim is to explore the conflicting demands of different engineering specialisms. Students work in teams of three with one each responsible for the aerodynamic, flight stability and stuctural aspects of the design.

Fourth Year:
Advanced Aerodynamics in Module 4A7 - Aerodynamics
This course aims to provide at least some of the answers to the question "why are real aircraft the shape they are?". It primarily focusses on fully 3D viscous swept transonic wing theory, including the non-oscillatory aeroelastic behaviour of such designs and its implications for aircraft stalling stability, and ends with an introduction to separated conical flows and slender delta wings. The course makes significant use of real-world examples drawn from the aviation industry and concludes with a visit to the Imperial War Museum Duxford to view particular aircraft "in the metal".


DEMONSTRATING

Fourth Year:
Transonic Wing Section Design in Module 4A7 - Aerodynamics
This coursework section involves the interactive design of a transonic aerofoil profile on a workstation in the DPO using an industry standard CFD code. The aim is to consolidate the lecture material and illustrate how the various design constraints compete in practice.


COLLEGE TEACHING

Jerome is Fellow of Trinity Hall where he is Director of Studies in Part I Engineering. He supervises Part IA TH Engineers in Kinematics and Dynamics in Two Dimensions, Dimensional Analysis, Mechanical Vibrations, and Structural Mechanics.
