Aircraft Entry Door Scuff Plate


An aircraft structure carry different load during different phases of flight.The modern aircraft structure design are  based on semi monocoque construction. In semi monocoque construction  all structural member of structures such as stringers,frame ,bulkhead and skin carries the loads.Fuselage skin is the principle load carrying member of semi monocoque construction design.All the loads acting on fuselage is  transferred from skin to internal member of fuselage structure.The integrity of fuselage skin is important for transferring the load efficiently from fuselage skin to internal member of fuselage structure.

Fuselage has number of opening in the fuselage structure for window,door,servicing panels,inspection access hole etc for access and servicing.Passenger/cargo door opening for passengers boarding/deboarding, cargo loading / off loading and inspection access hole for carryout  inspection of system components. Passenger and cargo door opening area in fuselage where external equipment such as aerobridge,step ladder and Baggage freight loader ( BFL ) come in contact with fuselage skin.During aircraft ground service operation such as alignment of aerobridge or BFl it may accidentally hit the fuselage skin cause damage to skin.In order to prevent skin damage in such prone area skin protection provided by scuff plate.

Fig 04 Replaceable Scuff Plate

Scuff plate is metallic and non structural parts.It is usually installed below passenger and cargo door opening area and protect door surrounding skin from accidental damage.Scuff plate is replaceable part and many aircraft operator replaces the scuff plate for cosmetic reason because it has many dents and scratches on it.

Flap and Slat Wing Tip Brake Location

Why Wing Tip Brake of Flap and Slat Installed at outboard of wing? The function of wing tip brake to hold and stop rotation of flap/slat transmission shaft when slat/flap control computer sense asymmetry, uncommanded or runways condition of flap/slat. Wing tip brake(WTB) work similar to pressure  off brake(POB).Pressure off brake installed in power control unit (PCU) and wing tip brake separately placed at wing tip. The contraction of WTB and POB similar to brake of an aircraft. As the brake has stator, rotor and piston housing similarly we have stator, rotor and piston housing  in WTB and POB . Pressure Off Brake                                                               Fig 1  Pressure  Off Brake POB consist of friction disc, spring and piston assembly for actuation of spring. When hydraulic pressure available spring compressed. Spring pressure removed from friction disc and transmission shaft turns freely. In absence of hydraulic pressure spring pressure acting on friction disc w

Aircraft Insulation Blanket

  Insulation blanket is heat and acoustic barrier.It is made of fiberglass wool.Fiberglass wool filled between waterproof polyurethane covers and edges are sealed to prevent water ingress.                                    Fig 1 Insulation Blanket on Fuselage Structure Aircraft necessarily create a lot of unwanted noise. The main source of noise in aircraft are engines and air flow, which transits through the fuselage and overall structure. In order to make aircraft interior quieter, an insulation blanket used. When aircraft at high altitude, the outside temperature is about -60-degree Fahrenheit. In combination with pressurization, aircraft insulation material helps keep the cabin warm by filling the space between the interior wall and the aircraft fuselage.   As we know that fire retardant material is must for all aircraft. The reason of choosing fire retardant material is to minimize the potential for a fire and help to prevent or slow flame spreads if a fire occur, which will pro
