What is hydraulic energy in airplane and how generate that? |
|
Answer» Hydraulic ENERGY systems PROVIDE hydraulic energy for hydraulic components in aircraft. Redundancy design is commonly used in modern aircraft to ensure safety and reliability. Several independent hydraulic energy systems are used to ensure the safety and reliability of SUPPLY hydraulic energy. The independent hydraulic energy system means each hydraulic source has independent hydraulic components, and can provide hydraulic power to the oil expensing system independently. Twin-engined aircraft, such as the Airbus A320, Boeing 737, Boeing 757 and Boeing 767 normally have three independent hydraulic energy systems. The Boeing 747 has four engines and has four independent hydraulic energy systems. The NAMES of hydraulic energy systems in different types of aircraft are different. Table 4.1 shows the distribution situations of hydraulic pumps in hydraulic energy systems in several COMMON passenger aircraft. |
