The small helicopters would be remotely controlled and would be able to send back pictures and data to a central command post. They would also be able to communicate with each other to co-ordinate their operations.
Professor Gerard Parr, Professor of Telecommunications Engineering at Ulster said the unmanned aerial vehicles (UAVs) could be used in a number of scenarios including to:
* Search for people lost in isolated areas like mountains, forests or moors.
* Monitor disasters like floods or forest fires which could cover thousands of acres.
* Survey biological disasters such as chemical factory fires and sample gas emissions.
* Act as a communications platform where normal radio or mobile telephone transmissions are impossible or disrupted.
Professor Parr and his colleague Professor Sally McClean, Professor of Mathematics at Ulster, are working with scientists from University College London and the University of Oxford on the project. The teams have been awarded a prestigious £2.2m grant from the Engineering and Physical Sciences Research Council, the UK government’s leading funding agency for research in engineering and physical sciences, to investigate the development of the innovative systems and control technology.
Ulster’s expertise lies in the fields of telecommunications protocolds, radio communications, control and optimization of data management. The project runs from September this year until February 2012.
Professor Parr said: “We intend to use helicopter models as the platform for the new technology. We need a vehicle that can carry cameras and various sensors as well as the control mechanisms. A helicopter-type unmanned vehicle would be able to hover and would be more stable than an aeroplane for specific operations.
“Ultimately, the intention would be to send several of these unmanned vehicles, a swarm, out at one time to enable them to cover a very large area in the shortest possible time. Using infra-red and other sensors they could scan large areas like Dartmoor, the Mournes or the Lake District using intelligent search algorithms to identify a target whilst at the same time avoiding collision with one another if someone was reported missing.
“They would be controlled from a command base, which could be a jeep roving about the area or possibly airborne, but they would also be able to act autonomously. For example, if one UAV detected a signal such as a heat source, or a radio pulse from clothing or a mobile phone call, it could leave the other vehicles to investigate and then return and relay its information back to base.” There are many engineering and research challenges to be addressed as part of the project, not least to design adequate energy awareness protocols that will optimise in-situ operations as long as possible in support of a particular mission.
The UAVs could stay aloft for up to half a hour, flying at 20-30mph or even faster over a range of 5000 metres or more depending on payload, mission function and power levels.
The vehicles could be equipped with application specific sensors, including heat sensitive cameras and video, gas particulate filters, wireless radio communications and GPS technology. They could organize their own search, determine if the object found was what they were looking for and then report back to the ground controller.
As well as Professors Parr and McClean, the multi-disciplinary team consists of Professor Steve Hailes and Dr Simon Julier from the Department of Computer Science at UCL and Dr Niki Trigoni and Dr Stephen Cameron from the Oxford University Computing Laboratory who have international reputations in the areas of hardware sensor design and helicoptor platforms.
The team were awarded the grant following a highly competitive process for funding under the EPSRC WINES III (Wireless and Wireless Intelligent Networked Systems) Research Programme. A total of 61 consortia proposals were originally submitted, with 15 shortlisted and four going through to the final selection.
The scientists will build prototypes of the unmanned vehicles with external partners including BAE Systems Operations Ltd, Thales Research and Technology UK Ltd, Communications Research Centre, Canada, BT Research Laboratories UK, Boeing Co, USA and the UK Home Office Science Development Branch.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
