We are now 18 months into the AutoDISC project. The following update summarises the progress made since the Q5 Partner Meeting.
The Q6 Partner Meeting was held at the Plant Integrity facility in Cambridge; a demonstration of the gantry system software control was performed at InnoTecUK.
Plant Integrity and JackWeld have been collaborating on the ultrasound testing (UT) sensor development, along with the associated end-effector. JackWeld has produced a prototype end-effector comprising a number of modular interchangeable components. JackWeld has also developed a prototype water interface management system to provide the required coupling between the sensor and the test piece.
NetComposites has built a falling-weight impact rig to assist with the development of manufactured defects that accurately replicate delamination in composite materials. A new test sample (representative of a stringer section) including defects, has been produced for inspection trials.
KCC has collaborated with PI on the development of the UT probe software. KCC demonstrated wireless communication between the UT sensor and Windows/Android devices. KCC has also worked with InnoTecUK to define the point-to-point movement strategy of the gantry arm; and with BIC to process the data for visualisation of defects.
BIC has refined the filtering/processing/thresholding strategies and algorithms, and experimented with excitation frequencies and scan settings. Their work relating to signal processing and image analysis will be presented at the Aerospace Event 2016 (13-14 April 2016, Bristol), organised by the British Institute of Non-Destructive Testing (BINDT).
The AutoDISC consortium continues to strengthen links with key industrial organisations to gain interest in the project, and to reinforce the ideas behind the technology being developed.
