We recently had one of our guys go over to Sydney to fly on the A380.
He had some interesting facts to present on his return.
MTOW (Maximum take off weight) 562 tonnes vs a 747-400 at 397 tonnes
73 m long (3 metres longer than a 747)
Vert fin 24.1 m (7 stories) 5m taller than a 747
Wing span 79.8 m (15 m more than 747 at 64.9m)
Wing area an incredible 845m2 which is 54% more than a 747!!!!!!!
How big is your section?????
Believe it or not it is a group C aeroplane (along with 737's, A320's etc). 747 is group D.
Max landing weight of 386000 kg (almost MTOW for a 747) 747 max ldg weight of 285,750kg
At max landing weight it has a VREF of only 138 kts which is 20 kts slower than a 747 at some 100,000 kg lighter.
It only needs 2010m to land vs a 747 at 2260m at their respective max ldg weights.
ISA + 15 SL takeoff of 2940m (590m less than 747) at MTOW's.
It has a truly amazing wing.
At MTOW it can climb direct to FL350 in 28 min. A 747 can only get to FL310. It will take the 747 about 7 hours and some 3600nm before it can get to FL350. At that time the A380 will have stepped up to FL390. The 747-8I is going to be even worse only just getting to FL 350 after some 9.5 hrs!!!! At that time the A380 will be at FL410. Big weather and economy advantage being up there!
46% less noise footprint than a 747
Other facts
- The most complex engineering project ever undertaken.
- 10,000 bolts hold the 3 main fuselage parts together.
- 8000 to attach each wing.
- APU can provide enough power and heat to supply 800 family homes.
- Cruising at 42,000 ft the cabin alt is only 6000 ft
- Carries 310000 litres of fuel or 248000 kg(equiv of 21 tankers). 747 has 172,000 kg approx.
- RR Trent 900 Engines produce 80,000 lb thrust
- Fan diameter 3.05m or 10 ft.
- Fan turns at max of 3000 RPM. Tip speed Mach 1.3
- Each eng sucks in 1.25 tonnes of air per second.
- 50 to 1 compression ratio
- gas nozzle speed 1600 kmh
- The 70 blades in engines high pressure section rotate at 12,500 rpm on takeoff and each blade produces and incredible 900HP!!!!!
- If you applied the same blade cooling technology to an ice cube you could place it in an oven at 200 degrees C and it would never melt!
- Each engine has 20,000 components and weighs in at 6350 Kg.
- With an aircraft of this size you could only just imagine the amount of electrical wiring involved..some 500 KM worth of wiring looms. This is where it all went wrong for Airbus. They had a problem with their CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) at Hamburg. When the wiring harnesses were laid out it was found that some were too short and others too long....bugger. As the wires cannot be sliced they had to start all over.
- These production setbacks have pushed the projected break even number out from the initial 270 to 420.
- Current orders are for 165.
- 13 are scheduled for delivery in 2008, 25 in 2009 and full annual production of 45 aircraft reached by 2010.
Clever wee Frenchmen!!!!!
