Personal profile


Dr Juliana Early is a Reader in the School of Mechanical and Aerospace Engineering, Deputy Head of School and Deputy Director of the Sir William Wright Technology Centre (WTech) at Queen's University Belfast. She was awarded her PhD from the University of Glasgow in 2006, and joined the academic staff in the School of Mechanical and Aerospace Engineering at Queen’s University Belfast in 2007. She is a Member of the Royal Aeronautical Society (MRAeS), a Fellow of the Higher Education Academy (FHEA) and achieved Chartered Engineer (CEng) status in 2010.   She is a regular reviewer for a number of leading international journals (AIAA Journal, The Aeronautical Journal, Journal of Aerospace Engineering, Aerospace Science and Technology, etc).

Her research interests in clean propulsion technologies and optimisation have generated over 70 publications in peer reviewed journal, international conferences, technical report and book chapters. in 2017 was appointed as the Deputy Director of the £6m William Wright Technnology Centre at Queen's University Belfast. She has successfully supervised 8 PhDs to completion in the field of applied aerodynamics and clean energy, as well as mentoring 15 postdoctoral research fellows in a range of FP6/7, Technology Strategy Board, EPSRC and direct industrially funded research programmes.  She was Queen’s University Belfast Principle Investigator (PI) on the FP6 funded Unsteady Effects in Shockwave Induced Separation (UFAST 2007-2008), QUB PI on the Technology Strategy Board/Bombardier co-funded Environmentally Friendly Engine programme (EFE 2007-2012), QUB PI on the €5m FP7 funded REsearch on a CRuiser Enabled Air Transport Environment (Recreate 2011-2015) and QUB PI on the €1.8m H2020 Clean Sky 2 Adaptive Area Nozzle for Ultra High Bypass Nacelle Technology (AvAUNT 2016-2020) as well as securing funding through the NI Department of Employment and Learning (DEL) for a range of PhD scholarships.  She is the QUB CI on the £3.2m Innovate UK IDP13 funded Next Generation Hybrid Electric Vehicle (NextGenHEV 2017-2020) and QUB CI on the £3.99m Innovate UK IDP14 funded Next Generation Battery Electric Vehicle (NextGenBEV 2018-2021) programmes, and leading the £2.62m EPSRC funded StreetZero programme (2019-2024).

MEE1035 Introduction to Aerospace Engineering

Students are introduced to the concepts of aircraft flight mechanics, performance and design by engaging in the actual practice of engineering through participation in two active learning projects, each of which involve working in teams:

Flight Experience Project, which involves designing a small light aircraft using simple analytical analysis using MS Excel and practical flight simulation;
Structural Design Project, which involves the structural design, analysis and testing of an idealised aircraft component , complimenting a number of additional Stage 1 modules

AER2007 Aircraft Aerodynamics and Performance 2 (Module Coordinator)

The course reviews fundamentals of aircraft performance  considering cruise, climb, take-off, landing  and accelerating flight considerations.  Basic principles of stability and control are introduced, with the distinction between static and dynamic stability discussed. Methods for calculation of forces on thin wing sections and finite-span wings in low-speed flow are developed from fundamental fluid principles, introducing concepts of stream functions, velocity potentials, vorticity and circulation for flow analysis.  Laminar, turbulent and transitional boundary layer development are discussed with relation to aircraft performance, and methods for their preliminary analysis established. 

AER2008 Compressible Flow and Propulsion 2 (Module Coordinator)

The course introduces students to the study of compressible flows and high speed aerodynamics.  The basic theory behind compressible flow is first introduced reviewing fundamentals of gas dynamics, thermodynamics and one dimensional isentropic flows.  The principles behind the development of the shockwave (normal/oblique) and Prandtl-Meyer Expansion fan are introduced, extended to analysis of nozzle and diffuser configurations.  Shock-Expansion theory and Ackeret’s theory are also introduced.  Focus is placed on where these phenomena are encountered in aerospace engineering, with specific relevance to aircraft engine intakes and external supersonic aerodynamics. The design of the jet engine is then introduced, alongside methods for analysis to understand performance characteristics which are typically associated with high performance aerospace applications.
