    IEP AD 01 Aerospace Fisherman's Bend, Victoria

    Vibration energy harvesting for airframes

    The position is located within the Airframe Diagnostic Systems group in the Aerospace Division, at Fishermans Bend, Melbourne. The successful applicant will be expected to be a significant contributor to a programme of research investigating potential diagnostic health monitoring systems for use on Australian Defence Force air vehicles. In particular, the successful applicant will be involved in the development of techniques for parasitic energy harvesting from vibrating aircraft structures. These energy harvesting devices should be capable of harvesting power from airframe accelerations using novel piezoelectric materials, with the goal of powering structural health monitoring devices. The job itself will involve assisting DST Melbourne personnel in the development, manufacture and evaluation of vibration energy harvesting devices. The applicant will be required to carry out a variety of different tasks. Tasks include mechanical and electronic design, code/script development, model development, and experimental validation. The experimental studies will require taking measurements under laboratory conditions and then analysing the data where necessary and reporting on the findings. The applicant can expect to develop various specific skills during the 12 month posting e.g. MatlabTM scripting may be used for COMSOLTM finite element Multiphysics modelling. MatlabTM may also be used for automation of various laboratory tests. SolidworksTM may be used for the development of mechanical design ideas for 3D printing of devices. The applicant may be exposed to C, C++, required for low power embedded microcontrollers, and high power Digital Signal Processing. Other scripting approaches may be implemented for LTspiceTM electronic simulations (PerlTM, VBATM). Additionally, the applicant has the option of developing their technical communication skills by presenting their research findings at an Australian scientific/engineering conference.

    (i) Under the direction of DST Melbourne staff, develop mechanical and electronic designs, including software for acceleration based energy harvesting devices to provide power to aerospace structural health monitoring devices, using novel piezoelectric materials. (ii) As required, assist in manufacture of the components developed in part (i) using 3D printing and design. (iii) Laboratory based experimental validation. (iv) Recording and analysis of data from experiments and reporting on the findings.

    Aerospace and mechanical engineering, electronics engineering, materials engineering, physics, mathematics and software development.

    12 month project. Excellent academic results throughout undergraduate degree.

    Flight demonstration of autonomous airframe diagnostic sensor systems

    The position is located within the Airframe Diagnostic Systems group in the Aerospace Division, at Fishermans Bend, Melbourne. The successful applicant will be expected to be a significant contributor to a programme of research investigating potential diagnostic health monitoring systems for use on the Australian Defence Force aircraft fleets. In particular, the successful applicant will be involved in developing a laboratory flight demonstration of autonomous airframe diagnostic sensor systems, including vibration energy harvesting approaches and airframe sensors. The flight demonstration involves the development and validation of an Airframe Sensor Testbed based on a tethered DJI S900 hexacopter drone. The job itself will involve assisting DST Melbourne personnel in development and validation of an Airframe Sensor Testbed, and the testing and validation of vibration energy harvesting devices and airframe sensor systems with a focus on ultrasonic and thermal/infra-red based interrogation approaches for cylindrical composite beams. The applicant will be required to carry out a variety of different tasks. Tasks include mechanical and electronic design, code/script development, model development, and experimental validation. The experimental studies will require taking measurements under laboratory conditions and then analysing the data where necessary and reporting on the findings. The applicant can expect to develop

    Development of baseline EC135 helicopter flight dynamic model and integration into simulation environment.

    This project is in support of project AIR9000 Phase 7. The successful candidate will use FLIGHTLAB to develop an EC135 helicopter flight dynamic model. The model developed will be integrated into a pre-existing Human-in-the-Loop simulation environment. DST Group develops high fidelity helicopter flight dynamic models for the whole range of aircraft available in the ADF fleet. These models are used to support deliverables involving helicopter simulation tasks. The models that are developed are engineering simulation models, rather than training simulation models. The engineering models allow DST Group to re- configure and measure all aspects of the helicopter simulation, such as measuring control system forces or investigating specific failures in the control system. This ability is crucial when DST Group supports a helicopter incident or accident investigation.

    - Learn FLIGHTLAB software - Develop flight model using FLIGHTLAB - Modify and develop a PID based control system - Integrate flight model into a pre- existing simulation environment using MATLAB and C++

    - Helicopter flight dynamic modelling - Control Systems

    Familiarity with the following - Linux - MATLAB - C, C++ programming

    12 month project. Successful candidate will be trained on the FLIGHTLAB flight model development environment.

    Autonomous Diagnostic Thermal Imaging for High Performance Engineering Structures

    The position is located within the Airframe Diagnostic Systems group in the Aerospace Division, at Fishermans Bend, Melbourne. The successful applicant will contribute to the development and testing of a new technology for autonomous diagnostic thermal imaging of high performance airframe structures using miniature infrared microbolometer cores. It represents the next generation of the MiTE system, a breakthrough developed by the Defence Science and Technology Group and successfully applied to all three variants of the Joint Strike Fighter aircraft, the most advanced fifth generation fighter in the world. As part of an ongoing effort to broaden awareness of this powerful full-field diagnostic technique, DSTO has created a freeware version that can be downloaded from its public web site at http://www.dsto.defence.gov.au/opportunity/mite. Interested applicants can find relevant information about the capability at this site.The role itself will involve assisting DST staff in a laboratory evaluation of the next generation of this technology. The successful application will work with miniature microbolometer thermal imaging cores, mems accelerometers, laser displacement sensors, wireless communications and be exposed to a range of concepts in image and signal processing, structural and thermal finite element modelling, and fatigue and structural mechanics. The tasks will include experimental investigation of system performance, designing and developing hardware packaging solutions and using C++, Matlab and
