The B1 Lancer is a four-engine, variable-sweep wing strategic bomber used by the United States Air Force. First envisioned in the 1960s as a supersonic bomber with sufficient range and payload to replace the Boeing B-52 Stratofortress, it developed primarily into a low-level penetrator with long range and supersonic speed capability.
The B1B entered service with the United States Air Force (USAF) in 1986.
The bomber is commonly called the "Bone" (originally from "B-One"). With the retirement of the EF-111A Raven in 1998 and the F-14 Tomcat in 2006, the B-1B is the U.S. military`s only active variable-sweep wing aircraft.
The B-1 has a blended wing body configuration, with variable-sweep wing, four turbofan engines, and triangular fin control surfaces. Forward-swept wing settings are used for takeoff, landings and high-altitude maximum cruise. Aft-swept wing settings are used in high subsonic and supersonic flight. The B-1`s variable-sweep wings and thrust-to-weight ratio provide it with better takeoff performance, allowing it to use more runways than previous bombers. The length of the aircraft presented a flexing problem due to air turbulence at low altitude. To alleviate this, the manufacturer included small triangular fin control surfaces or canards near the nose on the B-1.
Its maximum speed is Mach 1.25 (about 950 mph or 1,530 km/h at altitude), but its low-level speed increased to Mach 0.92 (700 mph, 1,130 km/h). Technically, the current version of the aircraft can exceed its speed restriction, but not without risking potential damage to its structure and air intakes. To help lower its radar cross section (RCS), the B-1B uses serpentine air intake ducts and fixed intake ramps, which limit its speed compared to the B-1A. Vanes in the intake ducts serve to deflect and shield radar emissions from the highly reflective engine fan blades.
-A delayed ERC dial on the BODY affects both the landing gear and landing gear doors.
-An ERC dial on the BODY raises or lowers both flaps.
-A second ERC dial on the BODY raises or lowers the flaps opposite each other for banking turns.
-These were included so you can have people in your aircraft without adding a fully textured and clothed M4 figure to the scene.
