Enhanced battery concept

Many battery technologies were assessed besides the conventional Ni-Cd type. The best candidate was the Nickel Metal Hydride type owing to its high energy density (and therefore, expected lower weight); however, they were finally discarded due to higher cost and excessive sensitivity to temperature operation � in particular, below cero degrees the performances are rather poor-. So, all battery sets are of Ni-Cd type, and revising and optimizing the mission requirements achieved the attained weight reduction with respect to the previous PTD battery arrangement:

- Measuring power demands under different operating conditions; it was done as testing actuators at CESA site on ground
- Specifying with more precision the flight profile and actuation times; it was assessed and finally established along Tasks 1.2 and 1.3.
- Applications: Weight/size optimisation of power supply for electrical actuation systems to be used on UAVs (Unmanned Aerial Vehicles).
