2. Facts
After finding the coefficients of lift and drag I was finally able to calculate the glide ratio. The success of the B-2
was proved in Operation Allied Force, where it was responsible for destroying 33 percent of all Serbian
targets in the first eight weeks, by flying nonstop to Kosovo from its home base in Missouri and back..
Many aspects of the low-observability process remain classified; however, the B-2's composite materials,
special coatings and flying-wing design all contribute to its "stealthiness. At crusing speed, the engines
exert 200kN of force. , are key members of the aircraft contractor team. The B-2's low observability is
derived from a combination of reduced infrared, acoustic, electromagnetic, visual and radar signatures.
The B-2 brings massive firepower to bear, in a short time, anywhere on the globe through previously
impenetrable defenses.
3. How to Control
You have to be familiar with the aircraft to
control perfectly. On the wings there are flaps
that if you press a certain button, the flaps will
go down to go up, up to go down and 1 up
and 1 down to go side ways. There are also
flaps on the tail fin.
7. Description
The force needed to keep an airplane in the air is called ‘Lift’. Lift is produced
by forcing air to flow over the wings. The construction of the wings is such
that the air flowing over the top surface has to travel further, and it
therefore travels faster, than the air under the wing. This causes the
pressure of the air on the top of the wing to be lower, and so effectively
the wing is sucked up by this lower pressure, and flies. Lift is produced
independently of power from the engine. The engine produces ‘Thrust’,
which gets the aircraft moving along the runway, so that air flows over the
wings. Thrust also overcomes ‘Drag’, which is the force which tries to
oppose the motion of the bomber through the air. The presence of the
airplane – or any other object – causes friction; and this is a type of drag.
The other force involved is ’Weight’, and the weight of the airplane
determines how much lift is required to get it into the air. As long as there
is enough lift to overcome the aircraft’s weight, and enough thrust from
the engine to overcome the drag, then the plane will fly. Even if the
engine stops, if the bomber is allowed to descend in a glide, the air over
the wings will generate enough lift to keep it airborne, while the pilot
prepares for a landing.
