how does a b2 bomber acheive flight?

Question

thrust
lift
yaw
roll

Answer 1

sticky is a moron

It is capable of all-altitude attack missions up to 50,000ft, with a range of more than 6,000nm unrefuelled and over 10,000nm with one refuelling, giving it the ability to fly to any point in the world within hours.

Its distinctive profile comes from the unique 'flying wing' construction. The leading edges of the wings are angled at 33° and the trailing edge has a double-W shape. It is manufactured at the Northrop Grumman facilities in Pico Rivera and Palmdale in California.



The B-2 is a low-observable, strategic, long-range, heavy bomber capable of penetrating sophisticated and dense air-defence shields.

The aircraft carries all its weapons internally and is fitted with two separate weapons bays in the centre of the aircraft. The B-2 has the capacity to carry up to 40,000lb of weapons, including conventional and nuclear weapons, precision-guided munitions, gravity bombs and a range of maritime weapons.

Each weapons bay is equipped with a rotary launcher and two bomb-rack assemblies. In tests, the B-2 successfully released B-61 and B-83 nuclear and Mk 84 conventional bombs from the rotary rocket launcher, and Mk-82 and CBU-87 conventional weapons from the bomb racks. The B61-11 is an earth-penetrating nuclear bomb for use against deeply buried and hardened targets. The B83 is a strategic free-fall nuclear bomb. The B-2 can also carry the AGM-129 advanced cruise missile, which is a strategic cruise missile with a range estimated at up to 1,500 miles.

16 satellite-guided JDAM (Joint Direct Attack Munition) missiles can be carried. Northrop Grumman is converting the B-2 bomb rack assembly to a new 'smart' configuration, which will increase the number of JDAMs which can be carried to a maximum of 80. The aircraft will also be fitted with the Joint Stand-Off Weapon (JSOW), Joint Air-to-Surface Stand-off Missiles (JASSM) and the Wind Compensated Munitions Dispenser (WCMD) and will be able to carry up to 80 115kg Small Diameter Bombs (SDB).

A Generic Weapons Interface System (GWIS) has been fitted as part of the block 30 upgrade. The GWIS is an integrated digital software package, which allows the B-2 to carry different mixes of stand-off weapons and direct attack munitions on a single sortie, enabling the aircraft to attack up to four different types of targets on a single mission.

The B-2's navigation suite includes a Rockwell Collins TCN-250 Tactical Air Navigation system (TACAN) and a VIR-130A instument landing system.

The B-2 Spirit stealth bomber has the capacity to carry up to 40,000lb of weapons, including conventional and nuclear weapons. The communications equipment is supplied by Rockwell Collins. A Milstar military strategic and tactical relay satellite communications system is installed in block 30 aircraft.

The aircraft have been upgraded with Link 16 communications link.

The aircraft is powered by four General Electric F118-GE-100 turbofan engines internally mounted in the body of the wings. The engines have an exhaust temperature control system to minimise thermal signature.

The engines, rated at 77kN, provide a high subsonic speed and a maximum gross take-off weight of 336,500lb. In-flight refuelling gear is installed in the top centre line of the aircraft behind the cockpit.

Answer 2

The B2 is a flying wing design. The entire body of the aircraft produces lift. The tricky part with this kind of design is the inherent instability. But with today's technology they have a way around that. There are five flight control computers on a B2. Three operating at a time, with two back ups. These computers make tiny control corrections many times per second in order to force the aircraft to fly smoothly.

Answer 3

It flies pretty much like anything else but with computers doing some smart stuff to make up for the apparently missing surfaces. The controls are much easier with computers, however there have been flying wings for many years, so the computers make it easy, but it was already possible.

thrust - 4 General Electric F118-GE-100 turbofan jet engines producing 17,300lb.st each, burried in the wing with the inlets and exhausts shielded as much as practical

lift - in the usual way, the air goes further to get over the top of the wing than under the bottom so it develops a pressure difference due to the Bernoulli principle.

yaw - that's the interesting one, you increase drag on the wing you want to yaw towards. Mostly you want to roll whilst avoiding yaw, but the principal is the same, you opperate upper and lower control surfaces in opposition so that you increase lift and drag but also dump the increased lift leaving just the drag which induces yaw.

roll - Same as any aircraft, increase lift on one side and decrease it on the other.

Answer 4

The B2 achieves flight just like any other airplane. It is shaped like a wing and generates lift by moving thru the air. Its unique characteristics require different control surfaces and techniques and the use of tremendous computer power made it all possible.

Answer 5

Just like the F-4 Phantom, if you put big enough engines in it, anything can fly. But once those are gone, it falls like a rock.

Answer 6

....be it the B-2, the B-1 a B52 a Sopworth Camel... they all become air-born the same way... wind over the wings.... different take off speeds...yes...

Answer 7

The b2 is proof that anything can fly if you give it enough thrust......
