The aircraft's main power supply is composed of generators driven by the aircraft engines, power control and protection equipment, etc. These devices provide ample electricity during flight. Since a typical engine has 1 to 2 generators, multi-engine aircraft have multiple generators, with each generator's power output meeting the entire aircraft's needs. Normally, two generators operate together, but not at full capacity. In the event of a generator failure, the remaining one will immediately switch to full load operation.
Differing from civilian electrical systems, aircraft operate on a 115V, 400Hz power supply, with a higher system frequency leading to reduced copper and steel materials in generators and transformers. This results in lighter weight and lower costs, but it also means that the inductive resistance of electrical equipment and wiring increases, the capacitive resistance decreases, and losses rise, thereby lowering transmission efficiency. The aviation industry is known for the phrase "striving to reduce every gram of weight." Therefore, to minimize size and weight, aviation generators are required to use high frequencies. It is estimated that under the conditions of 115V and 400Hz, the power-to-weight ratio of the equipment is quite high.
The ground power system is the upper-level energy supply unit for the integrated well-bear platform. To meet the diverse needs of our customers, our company has developed a variety of single-engine power supply systems and centralized power supply systems suitable for civilian and general aviation aircraft types.
