BERNOULLI’S PRINCIPLE

Bernoulli's principle and Venturi tubeBernoulli’s principle  states that when  a fluid flowing through a tube reaches a constriction or narrowing  of the  tube  the speed  of  the  fluid  passing through the constriction is increased and its pressure is decreased.

MAIN LANDING GEAR (MLG)

The tricycle gear is more stable during ground operations and makes landing easier, especially in crosswinds. It also maintains the fuselage in a level position that increases the pilot’s visibility. Nearly all Navy aircraft are equipped with tricycle landing gear.

A main landing gear assembly is shown in figure 1-11. The major components of the assembly are the shock strut, tire, tube, wheel, brake assembly, retracting and extending mechanism, and side struts and supports. The shock strut absorbs the shock that otherwise would be sustained by the airframe structure during takeoff, taxiing, and landing. The air-oil shock strut is used on all Navy aircraft. This type of strut is composed essentially of two telescoping cylinders filled with hydraulic fluid and compressed air or nitrogen.

Air Force officials have scheduled to deploy two contingents of F-22A Raptors to the Pacific theater in January 2009 for approximately three months. Current plans call for 12 of the fighters to deploy to Kadena Air Base, Japan, from Langley Air Force Base, Va., and another 12 to deploy to Andersen Air Force Base, Guam, from Elmendorf Air Force Base, Alaska. The deployments support U.S. Pacific Command’s theater security packages in the Western Pacific.

12/16/2008 – HICKAM AIR FORCE BASE, Hawaii (AFNS)– Air Force officials have scheduled to deploy two contingents of F-22A Raptors to the Pacific theater in January 2009 for approximately three months.

Current plans call for 12 of the fighters to deploy to Kadena Air Base, Japan, from Langley Air Force Base, Va., and another 12 to deploy to Andersen Air Force Base, Guam, from Elmendorf Air Force Base, Alaska. The deployments support U.S. Pacific Command’s theater security packages in the Western Pacific.

The F-22A is a transformational combat aircraft that can avoid enemy detection, cruises at supersonic speeds, is highly maneuverable, and provides the joint force an unprecedented level of integrated situational awareness.

As part of continuing force posture adjustments to address worldwide requirements, the Defense leaders continue to deploy additional forces throughout the Western Pacific. This is the latest example of the flexibility U.S. forces have to meet their ongoing commitments and security obligations throughout the Pacific region.
