The UK Ministry of Defence’s (MoD) Defence Science and Technology Laboratory (Dstl) has completed test flights of the open-architecture integrated defensive aids system (DAS) at Salisbury Plain training area, UK.

Carried out as part of the Common Defensive Aids System (CDAS) Technology Demonstrator Programme (TDP), the testing was aimed at demonstrating how different components can be better integrated to provide a coherent approach across various aircraft types.

A £24m, three-year partnership between the MoD and Selex Es-led industry team comprising Thales, QinetiQ, and BAE Systems North America, the CDAS TDAP is focused at enabling easy integration of sensors and countermeasures into frontline aircraft to enhance protection against future threats.

An integrated infrared, laser, ultraviolet sensors and directed infrared countermeasure (CDIRCM) effector-equipped architecture was used for testing, which was also supported by VFX’s ground-based advanced multi-axis motion platform and a Lynx helicopter from the UK Army Air Corps Development and Trials (D&T) Squadron.

"The platform enables scientists to identify motion-based issues before actual test flights, which saves time and money."

The multi-axis motion platform replicated the aircraft’s movements, while Dstl scientists stimulated sensors at representative ranges, resulting in generation of numerous hours of test data, which has been used for CDAS development and also to de-risk the flight trials.

Dstl Sensors and Countermeasures Department source Barry Knight said the platform would enable scientists to identify motion-based issues before actual test flights, which saves time and money.

DAS system is made three components, in sensors for threat identification, effectors for subsequent destruction, and a DAS controller (DASC) for intelligent processing.

The flight data is currently being evaluated by the project team, as the Dstl considers the methods for utilising the systems for other defence benefits such as land and maritime projects.
