Dr Christie Maddock


Mechanical and Aerospace Engineering

Personal statement

Dr Maddock is an expert in mathematical modelling and system design optimisation for transatmospheric flight vehicles, including spaceplane-based launch systems. 

Dr Maddock received her undergraduate honours degree in 2002 in Aerospace Engineering with a concentration in Electronics and Systems from Carleton University in Canada. Her thesis was on the design of an optical inter-satellite link for a LEO-GEO data relay satellite system. Her doctoral research was conducted at the University of Glasgow on the dynamics, navigation and control of a spacecraft formation of solar concentrators in the proximity of an asteroid. Prior to obtaining her PhD, Dr Maddock worked for the Canadian Spectrum Engineering Division analysing and designing future communications satellites, and sitting on a number of working parties within the Radiocommunications bureau of the International Telecommunications Union (ITU).


Has expertise in:

    • Earth-to-space vehicle design
    • Spacecraft formation flying
    • Modelling and simulation of engineering systems
    • Satellite telecommunications
    • Evaluation and analysis of trajectory design for air/space vehicles
    • Design and analysis of proximal motion dynamics, open and closed loop control
    • Analysis and/or the development and simulation of software models
    • Consultation on the regulatory process for satellite frequency and orbital location

This collaborative project between the University of Strathclyde and Reaction Engines Ltd.\ builds on initial research within the Centre for Future Air-Space Transportation Technology (FASTT) at the University of Strathclyde developing an integrated design platform for quickly assessing design parameters based on optimised performance and operations for space access vehicles. This project extends upper atmosphere re-entry models developed at FASTT, targeting at assessing the trajectory from atmospheric entry to the end of the hypersonic phase, to include de-orbiting and gliding phase and to implement a number of numerical tools to improve the convergence rate of the optimisation approach. Reaction Engines' Skylon vehicle is used as a test case to analyse optimised descent trajectories for their standard mission profiles. Reduced order models were used, calibrated by high fidelity simulations, for the vehicle disciplinary models. The final code is able to optimise the descent trajectory, from de-orbiting to final approach. For this project, as well as for the entire design platform, importance was given to developing a consistent and robust software framework that will facilitate the use of the spaceplane integrated design platform as an open source tool in the future.
