Technology for maximum safety and power The Construction manufacturing Hawker safety plus power THE WORLD IS BECOMING SMALLER. AIRCRAT TRAVEL THOUSANDS O KILOMETRES IN A MATTER O HOURS. AIR ROUTES CONNECT ENTIRE CONTINENTS. A AILURE IN THE AIRBORNE ENERGY SUPPLY SYSTEM CAN RESULT IN CATASTROPHE. IT IS VITAL THAT ALL INSTRUMENTS ARE IN CONSTANT OPERATIONAL READINESS The cell is the basic component of the nickel cadmium battery, as with other accumulators, and consists of positive and negative electrodes, with a sinter plate design, separators, electrolyte, cell container and a vent. Sintered metal, made using nickel powder with a porosity of around 80%, acts as a carrier for the active mass in the negative and positive electrodes. This structure is stiffened by inserting a perforated nickel plate. The active material is introduced into the highly porous composite carrier in a liquid state, with the positive electrodes immersed in a nickel salt solution and the negative electrodes immersed in a cadmium salt solution. Extremely thin separators segregate the positive and negative electrodes. Each separator incorporates a gas barrier which is very temperature- resistant, preventing thermal damage to the cell even at high ambient temperatures or excessive charging voltages (known as thermal run-away). The positive and negative electrodes are combined, with alternate layers of separators, into a plate block containing the appropriate terminals. The plate block is then inserted into a cell container and cover formed from heat resistant plastic (Polyamide). inally, the container and cover are welded together using a special process to form a sealed unit. As an added safety measure, each cell is fitted with a special vent to ensure that the gases produced during charging can escape before excessive pressure builds as well as prevent the leakage of electrolyte should the battery be inverted.
Aircraft batteries for every application The Battery The battery typically consists of 20 cells housed inside a battery case. All hardware, including the container and cover, is made from stainless steel while the interior of the battery container is lined with heat resistant plastic. Soft rubber, which acts as a retainer for the cells, lines the cover and high conductivity nickel plated copper connectors are used for inter-cell connections. Tubes attached to the battery s side allow venting to take place, and a plug mounted on the front of the battery container connects it to the aircraft s electrical system. In addition, all batteries may be fitted with temperature sensors for thermal monitoring. The Design The Advantages 1. Negative electrode 2. Positive electrode 3. Separator 4. Plate block 5.

Cell container Low internal resistance allows a high current discharge, giving excellent power output for Auxiliary Power Unit (APU) operating in temperatures between -30 C and +70 C. High capacity at low temperatures and rapid recharge with constant voltage to 100% capacity ensures exceptional reliability even in emergency conditions. Initial high current and a constant voltage supply, resulting from Hawker s exclusive technology of thin electrodes with a very low internal resistance, delivers optimum charge during flight. The specially designed separator material remains stable even in high temperatures, ensuring a high level of safety and producing no thermal run-away. (Overcharging tests [28,5 V / 50 C / 500h] show no defects to the separator material as well as to the complete cells.) Optimum storage conditions of +10 C to +35 C and 45% to 75% humidity facilitate a long life expectancy. The cell design, with its high electrolyte content, gives rise to very low levels of self-discharge. Low water consumption, a plentiful supply of electrolyte and no decrease in useable capacity results in longer periods without maintenance.
Expertise you can depend on The Expertise Hawker has a reputation for unbeatable experience and unrivalled expertise in the manufacture of aircraft batteries. Hawker batteries ensure the utmost reliability for both commercial aircrafts and military fighter jets. Hawker safety plus power is the result of many years research into creating a battery that delivers a perfect power supply to all monitoring and control instruments; one that can be relied upon to operate at optimum capacity even under extreme conditions. The materials used in Hawker batteries are subject to stringent laboratory tests, and every stage of the manufacturing process meets the criteria set out in the ISO 9001 quality standard. inally, the Hawker nickel cadmium aircraft batteries comply with the highest requirements of airworthiness as set out by EASA / AA / AR IAC / OEMs and Ministry of Defence.
