Electrothermal Propulsion Concept – Conductive Water-Based System

This project investigates a conceptual electrothermal propulsion approach for small satellites, with a focus on water-based propellants and their potential for safe, low-cost, and scalable in-space propulsion.

The study explores the use of conductive additives, such as dissolved salts (e.g., sodium iodide), to enhance electrical conductivity during the heating phase. The objective is to assess whether improved conductivity can lead to more efficient resistive (Joule) heating, thereby improving energy transfer within the propulsion system.

From a thermal and propulsion standpoint, the work examines how energy input translates into propellant heating, expansion, and exhaust generation. It also considers the practical limitations of such systems, including achievable temperatures, efficiency losses, and the challenges associated with maintaining performance in low-power environments typical of small satellites.

The project is approached with an emphasis on physical realism, critically evaluating assumptions such as ionisation levels and the feasibility of additional electromagnetic effects. This ensures that the concept remains grounded in achievable engineering principles rather than theoretical overestimation.

Ultimately, the aim is to better understand the viability of simple electrothermal propulsion systems and identify where incremental improvements in efficiency may be achieved within realistic operational constraints.

Role: Concept formulation, thermal and propulsion analysis, and feasibility evaluation

UAV System Concept – Long-Endurance ISR Platform

This project explores the conceptual design of a compact electric unmanned aerial vehicle (UAV) intended for long-endurance surveillance and real-time situational awareness. The primary focus is on understanding how propulsion efficiency, onboard energy constraints, and payload integration collectively influence overall system performance and mission capability.

From a propulsion and performance perspective, the study considers the trade-offs between power consumption, endurance, and aerodynamic efficiency. Particular attention is given to how energy-limited systems can be optimised to maximise operational time while maintaining sufficient payload capability for EO/IR-based sensing.

In addition to vehicle-level design, the project adopts a system-level approach by examining how an airborne surveillance platform can integrate with ground-based systems for coordinated operations. This includes considerations around data flow, response timelines, and the practical constraints associated with real-time monitoring and decision support.

Overall, the work is aimed at developing a clearer understanding of the engineering trade-offs involved in designing efficient and practical UAV systems, particularly in applications where endurance and reliability are critical.
