MAIN LANDING GEAR (MLG)

Aircraft main landing gear

Figure 1-11 Main landing gear. conventional  type.

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.

JAGUAR – Aircraft For Men

French Air Force SEPECAT Jaguars fighter aircraft

This photo especially for Michel « Riri » (Hi, mate!).

Some called this fighter a/c « flat-bottom boat » with amusement, some said that the Earth was round to let the Jaguar take-off, and some others called the Jaguar an « aircraft for men ». Having worked on Mirage F1CRs and Jaguars as well, I was used to using the latter phrase. I loved the F1CR though I’ve always been captivated by the Jaguars’ way of working. This fighter was rough but efficient, and I even dare say « multirole in advance » for the RP36P photo pod fielded Jaguars’ squadrons many times in France and abroad.

Jaguars regularly carried out war missions, and I can easily understand why their pilots and mechanics were proud of having worked on such aircraft. (a special thought for the former 7th and 11th Fighter Wings)

Have a good day Riri, see you, mate!

DEW and FROST

Dew and frost - C-17 Globemaster III de-icing in Alaska

U.S. Air Force photo by Master Sgt. Keith Brown

ELMENDORF AIR FORCE BASE, Alaska – Members of the 703rd Aircraft Maintenance Squadron de-ice a C-17 Globemaster III from the 517th Airlift Squadron before a training mission. Heavy snow and weeks of sub-zero temperatures require extra effort from maintenance crews to keep the aircraft clear of ice and snow. The training mission included dropping Army Airborne Soldiers from Fort Richardson, Alaska, and conducting air drops of training bundles that simulate the Soldier’s equipment. (from AIR FORCE LINK)

DEW

Dew does not actually fall; rather the moisture condenses from air that is in direct contact with the cool surface. During clear, still nights, vegetation often cools by radiation to a temperature at or below the dew point of the adjacent air. Moisture then collects on the leaves just as it does on a pitcher of ice water in a warm room. Heavy dew is often observed on grass and plants when there is none on the pavements or on large, solid objects. These objects absorb so much heat during the day or give up heat so slowly, they may not cool below the dew point of the surrounding air during the night. Another type of dew is white dew. White dew is a deposit of white, frozen dew drops. It first forms as liquid dew, then freezes.

FROST

Frost, or hoarfrost, is formed by the process of sublimation. It is a deposit of ice having a crystalline appearance and generally assumes the form of scales, needles, feathers, or fans. Hoarfrost is the solid equivalent of dew and should not be confused with white dew, which is dew frozen after it forms.
