Review of DC Circuit Breakers for Submarine Applications

This review is conducted to as part of the evaluation of dc circuit breaker options for future submarines.

Assessment of Governor Control Parameter Settings of a Submarine Diesel Engine

This paper develops a low order engine model which is then used to investigate the performance benefits that can be obtained through proper tuning of the governor control parameters.

An Investigation into Performance Modelling of a Small Gas Turbine Engine

The purpose of this project was to enhance DSTO's capability in understanding and modelling the thermodynamic and performance characteristics of gas turbine engines. An engine performance modelling tool was developed and validated and different tools and techniques were evaluated. Infrared suppression related studies were also conducted

Improvements to Filter Debris Analysis in Aviation Propulsion Systems

This report describes the application of two DSTO initiatives to improve the analysis of oil filter wear debris to be used as a valuable adjunct to existing condition monitoring techniques.

HIFiRE program

DST Group and the US Air Force Research Laboratory (AFRL) are collaborating on the Hypersonic International Flight Research Experimentation (HIFiRE) program.

Effect of ageing on munitions safety

DSTG is leading an international collaboration that has conducted world-first full-scale experiments to investigate how aged warheads respond to external stimuli such as shock and bullet impact.

Engine health monitoring for the Joint Strike Fighter

Vibration-based prognostics and health monitoring (VPHM) technologies enable early identification and isolation of faults in the F-35 Joint Strike Fighter (JSF).

Propulsion and energy

Our propulsion and energy research covers engine, drive-system technologies and power systems for land, air, maritime and space platforms. 

Efficient power systems involves fuels, batteries, materials, other devices, architectures and power management to increase efficiency and power density for platforms, facilities and reduce weight for personal power. 

Engine and drive-system technologies incorporates hydrodynamics, thermodynamics, combustion research activities.
