For the aeroplane starter system and unplugged ground power (and in some newer aeroplanes for a form of battery APU), as backups to ensure continued operation in the event of power interruption, and in a few cases as the primary power source. Once upon a time, this was something like “lead-acid” – the sort of batteries you learned about in school, with lead and lead oxide anode and cathode, sat in a container of liquid or gel (usually sulphuric) acid. One unit of that was a “cell”, and groups of them joined together became a “battery”. By controlling the arrangements of cells within a battery, we could control voltage, and to a fair extent current. By using an acid gel, we could make the battery able to be used in an aircraft (or other applications such as a motorcycle) without spraying acid all over the place. To recharge the battery, you connected an external direct current source the other way around and the chemical balance would be restored.

Taking Flight On Another World
The Mars Helicopter, Ingenuity, is a technology demonstration model to test powered, controlled flight on another world for the first time. It hitched a ride to Mars on the Perseverance rover. Once the rover reached a suitable "airfield" location, it released Ingenuity to the surface so it could perform a series of test flights over a 30-Martian-day experimental window.
Thales Completes Successful First Flight Of New UAS With Range Capabilities Of Over 100 Km
• With a hybrid propulsion system for optimum safety, endurance and discretion, Thales's UAS 100 long-range unmanned air system for civil, government and military users will be able to operate at ranges of more than 100 km. • UAS 100 combines world-class flight safety performance with the compact design required for unmanned air systems, and complies with future European regulations for drone flights over populated areas. • The system will meet the requirements of a broad range of missions, including infrastructure inspection, coastal surveillance, border surveillance, event security, search-and-rescue and military operations.
Dutch Squadron Finalises F-16 Operations
