A380 Hydraulic System
The Airbus A380 four-engine airliner became the first commercial application of a 5000-psi system when it entered service in 2007. There are three continuously operating hydraulic systems designated green yellow and blue.
Boarding and deboarding passengers and.
. If the priamry fails the aircraft is still fully flyable. 2 Hydraulic Systems Green Yellow conventional hydraulics 12 tons lighter than triple hydraulic systems 2 Electro-Hydraulic Systems for critical flight applications Andrew Eccles in the Concorde simulator at Brooklands UK Photo RDC. The A380s hydraulic system is called 2H 2E meaning that is consists of.
The hydraulic system generates forces up to 5000 psi. The project is also intended at discussing and investigating about the new electro- hydrostatic actuators which uses this high hydraulic pressure. The A380 has two hydraulic systems.
And the normal system operating pressure for each system is 3000 psi. The Abex Division Kalamazoo Mich supplied hydraulic motors and the Abex Aerohydraul Division Mainz-Kastel Germany supplied variable-displacement hydraulic motors for the A380s flap system. Some extra things like slats dont work anymore but those arent critical for flight and landing.
The term hydrostatic refers to the transfer of. Read customer reviews find best sellers. Each system has its own hydraulic fluid reservoir and accumulator but fluids cant be transferred from one system to another.
Hydraulic systems pump reservoir filters plumbing and the replacement of the associated hydraulic actuators by electrically powered actuators results in weight savings. However the power depends on the design of the aircraft. It has hydraulic pump control and an efficient turbine design.
It will begin commercial flights in 2006. Toulouse France-Overall weight and fuel efficiency are important to an aircrafts performance so Airbus engineers looked past the 3000-psi systems typically used in large aircraft and designed the first-ever commercial 5000-psi hydraulic system for use in the A380 aircraftThe new high-pressure system provides the fluid power needed for controlling the. The A380 More Electric flight control actuation concept consists in eliminating one hydraulic system and replacing it with a set of.
The A380 Ram Air Turbine system has an axial-piston pressure compensating pump. A380 Hydraulic System 11049513. Although the A380 will certainly be more electric it will also be a much more hydraulic aircraft.
Every control surface has its electrically driven hydraulic self contained actuator. A380 AIRCRAFT CHARACTERISTICS - AIRPORT AND MAINTENANCE PLANNING HIGHLIGHTS Revision No. Ad Browse discover thousands of brands.
A hydraulic drive system is a quasi-hydrostatic drive or transmission system that uses pressurized hydraulic fluid to power hydraulic machinery. Rolls-Royce said Friday November 12 2010 the failure of a specific component of its Trent 900 engine caused a fire on a Qantas A380 superjumbo that forced the Australian airline into an emergency landing. Each hydraulic system has its own reservoir.
High Lift system Flaps inner mid and outer flap droop nose Slats Flaps Lever SFCC 2 SFCC Wing Tip Brake Wing Tip Brake Motor Control Electronics Slat PCU Flap PCU T-gearbox Asymmetry Position Pick-off unit A380 High Lift movables and system mechanical components similar concept as A340 Long Range AIRBUS SAS. It is designed to reduce time at the gate during critical stages for airlines. 4All hydraulic back-up functions ensured by local hydraulic generation system LEHGS owned by the function system.
The A380 is the widebody which can fly with all ship-wide hydraulic circuits failed With both ship-wide hyd systems failed there is sufficient hyd power to control the aircraft. The integration of the 5000-psi system on the worlds largest passenger aircraft contributed significantly to critical component weight and volume reduction in overall system design. The A380 is a completely new very high capacity very long range commercial transport aircraft powered by 4 RR Trent 900 or Engine Alliance GP7200 engines.
If the secondary hydraulics fail there are still extra electric actuators to move the control surfaces. How is the design of the RAT system. The reservoirs are pressurized by bleed air to prevent cavitation.
VC10 has a similar system. The major aim of the project is to investigate about the new hydraulic system of a380 and the reasons for increasing the hydraulic pressure from 3000 psi to 5 000 psi. However hydraulic power which has been used for decades and is well understood is the primary power source for A380 flight control says Dominique van den Bossche Airbus department head for.
You may find three types of pump control in this RAT. Rolls said in a statement that the failure was confined to a specific component in the turbine area of the engine. The eight engine-driven pumps rated at 5000 psi will deliver 48 gal of hydraulic fluid per minute producing a 1120-hp system - more than three times the hydraulic system horsepower generated on an Airbus A340.
The two-deck four-aisle A380 will seat 555 passengers. The normal source is engine 1 but if pressure becomes low bleed air is taken from the cross-bleed duct. 17 - Nov 0120 LOCATIONS CHG CODE DESCRIPTIONS OF CHANGE CHAPTER 1 Section 1-1 Subject 1-1-0 Introduction R CHAPTER 3 Section 3-3 R Subject 3-3-3 N Aerodrome Reference Code N CHAPTER 4 Section 4-5 Subject 4-5-4 R 135.
The A380 is highly compatible with existing airport infrastructure allowing for smooth airline operations and services for passengers.
