Futuristic Radar for UK’s Future Combat Aircraft

British engineers have revealed some of the newest concepts under development for the Royal Air Force’s (RAF) next generation combat air system.

The revolutionary technology is being delivered by Team Tempest, a UK technology and defence partnership formed by BAE Systems, Leonardo, MBDA, Rolls Royce and the RAF, and involving hundreds of high-tech companies, SMEs and academia across the UK.

Tempest is one of the UK’s most ambitious technological endeavours designed to deliver a highly advanced, adaptable combat air system to come into service from the mid-2030s.

This next generation combat aircraft will exploit new technologies as they evolve to respond to the changing nature of the battlespace, addressing increasingly high-tech and complex threats.

Recognising the fact that data holds the key, experts from the Team Tempest electronics lead, Leonardo UK, are developing new radar technology capable of providing over 10,000 times more data than the existing systems.

The sensor, called the ‘Multi-Function Radio Frequency System’, will collect and process unprecedented amounts of data on the battlespace – equivalent to the Internet traffic of a large city such as Edinburgh, every second.

This mammoth volume of information, processed on-board, will give Tempest a battle winning edge in combat situations, with the ability to locate and target enemies well before they are targeted themselves.

The new sensor will provide a range of abilities beyond traditional radar, with all-digital technology providing the operator with an exceptionally clear view of the battlespace and of potential targets.

Leonardo has already built complete sub-systems using the new technology and successfully tested them at the company’s site in Edinburgh with a path to airborne demonstrations in the coming years.

Split-Second Advantage

Separately, engineers at BAE Systems have begun flight testing cutting-edge concepts for Tempest’s ‘wearable cockpit’ technologies, designed to provide pilots in the cockpit or operators on the ground with split-second advantage.

The physical controls seen in current aircraft cockpits are replaced by Augmented and Virtual Reality displays projected directly inside the visor of a helmet, which can be instantly configured to suit any mission.

Concepts including human-autonomy teaming are also being developed, where a ‘virtual co-pilot’ could take on some of the pilot’s responsibilities. The virtual co-pilot concept is still under development, but could, for example, take the form of an ‘avatar’ built into the cockpit to interact with the pilot.

BAE Systems has also been trialing ‘psycho-physiological’ technologies, including eye-tracking, to study the operator’s physical and cognitive processes to better understand increasing exertion, stress, workload and fatigue.

BAE Systems test pilots are now testing these psycho-physiological technologies in controlled test flight conditions in a Typhoon aircraft.

The results will help understand a pilot’s cognitive behaviour and processes relating to brain activity, psychological rhythms and eye movement.

MBDA UK has also embedded one of its Human Factors Engineers within this wearable cockpit team, ensuring early introduction of weapons concepts that exploit these future technologies.

In another development, Rolls-Royce engineers have been developing advanced combustion system technology as part of the company’s power and propulsion work, where fuel is introduced and burned to release energy into the gas stream.

A next-generation system will need to be hotter than any previous platform, increasing the efficiency of the engine and meaning it can go further, faster, or produce less carbon dioxide.

Rolls-Royce has been exploring advanced composite materials and additive manufacturing as part of this work, producing lightweight, more power-dense components capable of operating at these higher temperatures.

These concepts are part of a wider research effort to develop technologies that could be used to create a next generation combat air system for the UK.

Collectively, the Team Tempest partners are developing more than 60 technology demonstrations in the fields of sensing, data management and autonomy.

Iain Bancroft, Director of Major Air Programmes at Leonardo in the UK, said: “The collaborative relationship between the Team Tempest alliance and our network of academic and SME partners enables us to bring together the ‘best of the best’ engineering talent from across the UK. We are embracing new ways of working as an integrated team to dramatically improve efficiency and pace – sharing intelligence and refining our concepts digitally to deliver innovations that will shape the next generation combat air system. Our new radar technology is a concrete example of the gains this approach has already brought, costing 25 per cent less to develop while providing over 10,000 times more data than existing systems.”

The ambitious military programme is expected to deliver significant benefits to the UK over the full lifetime of the programme.

It is a critical programme to ensure the UK is able to sustain its world-leading Combat Air Sector. It will also bring benefits through investment in people, early careers, technology and infrastructure, supporting the economy and long term prosperity of the nation.

In July, seven companies signed agreements to explore opportunities to work on future combat air concepts and underpinning technologies across Team Tempest including Bombardier Belfast, Collins Aerospace in the UK, GE Aviation UK, GKN Aerospace, Martin-Baker, QinetiQ, and Thales UK.

Team Tempest

The UK Combat Air Strategy and the launch of Team Tempest was announced at Farnborough Air Show in 2018. This strategy set out a bold vision for the UK’s future combat air capability and was underpinned by establishing the Team Tempest partnership.
