Pressure bulkhead to support the landing gear system Research Paper

Pressure bulkhead to support the landing gear system - Research Paper Example In ideal embodiments, pressure bulkheads diffuse excessive overpressure and underpressure exerted by the aircraft’s cabin load, thus avoiding cases of hard landing that can result in instability. According to Parker (2005), all structures of the creation, both the horizontal and vertical bulkhead can be achieved through the installation of an anticlastic exterior; that is, a double-curved structure complete with the depressions in opposite ways. An anticlastic surface is normally used for landing gear to its symmetry and balancing of the cabin load for stability. Pressure bulkheads are important to the landing gear architecture, mainly for stability purposes during landing and take-off (Bahrami, 2012; Currey, 1988). The portion of an airplane constituting the wheels, tyres, braking system, drag brace, and pressure absorption and distribution mechanisms is referred to as the landing gear or undercarriage. Additional parts connected to and working in tandem with the undercarriage may encompass retracting mechanisms, door panels, steering devices, and shimmy dampers (Canaday, 2012). Centrally-placed landing gear provides symmetric support to the aircraft, and ensures its uniform movement on the ground (Canaday, 2012). It also serves as the main proportionate means of diffusing any accumulations of energy created in the changeover from flight to landing roll, thus prevents the aircraft from landing by its side (Wright, & Cooper, 2008). Mair and Birdsall (1996) aver that the brakes, usually connected to the main wheels, came handy when the forward movement of the aircraft needs retarding: in light of this, a centrally placed gear provides stability in the navigation of the aircraft during retracting. According to Currey (1988), the popular structure of modern aircraft landing gear come in the form of a tricycle, with the primary gear fixed aft of a front nose
