Aircraft starting power supply is an indispensable equipment in the aerospace field. Its main function is to provide starting power for aircraft engines to ensure smooth ignition and operation under various environmental conditions.
1. Overview of aircraft starting power supply:
Aircraft starting power supply is a power supply device specially designed to provide short-term high-current output for aircraft. It is widely used in the starting process of aircraft engines, especially when the aircraft's own power system cannot provide sufficient power or needs to reduce the burden on the onboard battery.
Aviation starting power supply is usually composed of core components such as high-performance battery modules, power management systems, output control units and safety protection circuits to ensure the stability and safety of power output.
According to the power supply method, aviation starting power supply is mainly divided into direct current (DC) starting power supply and alternating current (AC) starting power supply.
DC starting power supply is mostly used for small and medium-sized aircraft, with a typical voltage of 28V DC or 270V DC; AC starting power supply is usually used for large commercial passenger aircraft and military aircraft, and its output specifications are mostly 115V AC, 400Hz, to match the requirements of aviation power system.
In addition, according to different usage methods, aviation starting power supply can be further subdivided into portable, vehicle-mounted and fixed types, which are suitable for different operating environments and security needs.
2. Technical parameters of aviation starting power supply:
Different types of aviation starting power supplies have different technical parameters, and the main indicators are as follows: Output voltage of aviation starting power supply: Aviation DC starting power supply usually provides 28V DC or 270V DC, and AC starting power supply generally provides 115V AC, 400Hz.
Peak current of aviation starting power supply: Aviation starting power supply can reach 1500A-3000A, which meets the instantaneous starting requirements of aircraft engines. Continuous current of aviation starting power supply: Generally 500A-1000A, depending on the power requirements of specific models.
Battery type of aviation starting power supply: Common ones are lead-acid batteries, nickel-cadmium batteries and lithium-ion batteries, the latter of which are becoming increasingly popular due to their high energy density and long life.
Operating temperature range of aviation starting power supply: Usually -40℃ to +60℃ to adapt to different climatic conditions. Weight of aviation starting power supply: The weight of aviation portable starting power supply is about 10-50kg, while fixed or vehicle-mounted ones can reach 100-500kg.
Charging time of aviation starting power supply: the fast charging mode can be fully charged within 2 hours, and the normal charging mode is 4-6 hours.
