How does the B-2?

Question

fly without a rudder or vertical stabalizer? I thought of this after looking @ somebody else's question. http://sg.answers.yahoo.com/question/index;_ylt=AkSpeWSvW69QZ5DfcDbZ0cuN5Qt.;_ylv=3?qid=20080223155810AAOQXpq

Answer 1

Yaw control on a flying wing is accomplished with a differential drag control.  The classic Northrop flying wings of the 1940s had a double air brake at the outboard end of each wing; that is, a speed-brake like control with two vanes, one opening up, and one opening down.  When closed they were streamlined with the wing.

These were operated by the rudder pedals.  Press the left rudder on a B-35 or B-49, and the vanes split open on the left side only, giving that wing more drag and imposing a left yaw force on the airplane.  Same for the right side.

Those gave control forces for coordinated turns about as effective as a normal rudder.  The B-2 has a similar device, but of course it is computer controlled.

Answer 2

both stabilisation /done  by stabiliser/ and maneuvering /made by rudder/ are completed by a independentely deployed air brakes or other means of increasing drag.

computers help to manage this task, much like the computers are essential in unstable planes like the typical, though old, f16

Answer 3

It uses elevons and rudders*  in the outboard

wing section.

they are flat and act as spoilers. see link below

Answer 4

The B-2 uses its ailerons and flaps (flaperons)(sp) to control its flight path. The flying wing design is aerodynamically more efficient than a conventional design but it took todays computers to make all the minute corrections needed to control the airplane successfully.
