Rockwell B-1B Bomber - Rod Conklin 76525, 3706

Files In This Package:

B1B_____ - These are the aircraft files. To use the plane
B1B_____.SIM simply copy them to your FS4 directory and
select the B1B like any other FS4 aircraft.
Nothing else is required.

B1B.AFX - This contains the packed assembly to use if you
have AFX.

REF-B1B.ZIP - This is the source SIM file that I used to
create the final aircraft.

Detailed Fuselage with USAF markings.
Working Flaps and leading Slats.
Working landing gear.
Working variable sweep wings.

Aircraft History and Specifications:

The Rockwell B-1 bomber actually was conceived and started in the
early 1970's as a replacement for the B-52. The program was cancelled
by the Carter administration and then reinstated in the early 1980's
by the Reagan administration. The B-1B, as the bomber was called after
the program was reinstated, was redesigned to fullfill a dual role.
It was to be a strategic bomber that could deliver nuclear cruise missiles,
and carry a conventional weapons load as well for non-nuclear conflicts.
One of its unique features is that it can fly at altitudes of 200 feet
and below at subsonic speeds utilizing a Terrain Following Radar (TFR)
system to control and fly the aircraft. This low altitude capability
allows the bomber to evade most enemy radar while delivering its payload
to the target. The B-1B became part of the Air Force's operational
inventory in 1986.

It might be noted that the low-level, high speed (just below Mach 1)
missions that this aircraft are designed for can be extremely dangerous.
Atleast one B-1B has crashed due to a bird strike while flying at low levels.
Fortunately, we have no such problems in FS4, unless somebody comes up with
a simulated flight of Whooping Cranes.


Type: Strategic/Tactical Bomber

Dimensions: Length: 144 Feet.
Wing Span: 137 Feet (Extended), 78 Feet (Swept Back)
Height: 34 Feet.

Weight: 477,000 (Maximum Takeoff Weight)

Power: 4 General Electric F101 Engines.


1) This aircraft is designed to fly at supersonic speeds at higher
altitudes and subsonic speeds at extremely low altitude. The FS4
version will also do this. In the actual aircraft, the wings are
swept back or extended to meet lift and speed requirements for
any given altitude and attitude (pitch). I have attempted to
simulate this variable sweep by making the wings swing back into
their fully swept-back position at speeds of 350 KNOTs and faster
and to remain extended below that speed. AAF would not allow varible
condition tests to sweep the wings differantly for differant speeds.

2) At speeds of 350 KNOTS or greater, if you extend the flaps, they will
appear to float beside the plane. This is because they are designed
to only be used with the wing in its fully extended position.
The variable sweep wing effect is made by defining two
wings for the aircraft in AAF and setting a test for 350 knots to
tell it which wing to display. In actual practice, the flaps would
probably never be used with the aircraft travelling faster than
350 knots.

3) The aircraft has two "LARCS VANES" (That is Low Altitude Ride Control
System in english) located at the front of the
fuselage. In the FS4 model, these are fixed, but in real life
these vanes act as "shock absorbers" to reduce pitch/yaw
oscillations or buffeting when the aircaft is travelling at
500 Mph at an altitude of 200 feet, otherwise the crew would feel
more like they were riding in a truck than an aircraft.

4) Finally, I patterned the performance of the SIM file for this
aircraft after the Concord SIM file parameters. It is similar in
top speed and handling, except that it does not have as high a
ceiling as the Concord and the B-1B can takeoff on a 4000 foot
runway. To approximate the actual instrumentation used by the
B-1B, I suggest using the EFIS panel when you fly it.
