There's no need for a traditional battery. The system that's still in development charges a hard composite material that could act as the structure of an aircraft, a vehicle or even a piece of soldier's gear.
Specifically, BAE Systems forsees the solar system to be used on a UAV or soldier system since weight is so crucial for both, said Darren Buckle, a manager for BAE Systems' Advanced Technology Centre. A battery usually just adds unnecessary weight.
A solar system could provide power for a long endurance UAV if the system can absorb solar rays even when it's not sunny. This is a challenge for BAE Systems engineers, Buckle said. It's one of the priorities for its development program. The engineers want to make sure the solar cells can power the UAV even on the many foggy or cloudy days here in England.
The solar cell was just one of BAE Systems' Advanced Material Technologies on display. Adaptiv Camouflage was also highlighted like it has been at other trade shows. BAE Systems has already shown it can cloak a tank with a material that uses metal pixels to alter the heat signature. It can make a tank look more like a car when viewed by its heat signature.
Thermoplastic spall liners were also seen here. BAE is not the first to make a spall liner and it's a surprise more are not in military vehicles. The idea of the spall liner is to contain blast fragments if an IED or RPG reach the inside of a vehicle. The flak that pings around a cabin is what often kills or maims the passengers. A spall liner absorbs those fragments protecting the soldiers or Marines inside.
