.1 Damages of a fuselage
fuselage is the main structure in the aircraft that holds crew, passengers and cargo. An aircraft fuselage structure must be capable of withstanding many types of loads and stresses, and at the same time with low weight.damage is unexpected physical injury of an aircraft which can lead to depressurization, loss of power or improper work of an aircraft system and it is caused by external things, such as birds strike, watering (corrosion), faults of a crew or else.two most frequently types of structural damages in a fuselage are the longitudinal cracks due the pressurization cycles and the circumferential cracks due the bending and torsion of the fuselage. These damages can occur along all the shape of fuselage: in the nose, in the glass part, at the joints., Monocoque, and the semi-monocoque solutions are found for the design of this structure. Truss or ramework types of construction have wood, steel or aluminum tube, or other cross sectional shapes which may be bolted, welded, bonded, pinned, riveted or machined into a rigid assembly.principal source of the stresses in this structure is the internal pressure in high altitude caused by difference of cabin pressurization and reduction of the outside pressure with increase in altitude, but the structure is subjected to other loads, as bending, torsion, thermal loads, etc.damages of a fuselage are represented in the following pictures. There are rupture holes in the nose of a fuselage, scratches, corrosion, and cracks.

were some accidents involving the damages of a fuselage:
, August 22 - Far Eastern Air Transport Flight 103 , a Boeing 737, disintegrates during flight and crashed near Taipei , Taiwan; severe corrosion in the fuselage structure leads to explosive decompression and disintegration at high altitude; all 110 on board are killed.
, July 13 - Southwest Airlines Flight 2294 , a Boeing 737-300 from Nashville to Baltimore makes an emergency landing in Charleston, West Virginia after a 14x17 inch hole opens in the skin of the fuselage at 34,000 feet (10,000 m), causing a loss of cabin pressure; the plane lands safely with no injuries.
, April 1 - Southwest Airlines Flight 812 , a Boeing 737, ruptures a hole in the fuselage at 36,000 feet , causing the cabin to lose pressure after takeoff from Phoenix Sky Harbor. The plane lands safely at Yuma International Airport, Arizona with all 118 people aboard uninjured.
.2 Damages of an engine
An engine is a machine <# "justify"> Today's modern airplanes are powered by turbofan engines. These engines are quite reliable, providing years of trouble-free service. However, because of the rarity of turbofan engine malfunctions, and the limitations of simulating those malfunctions, many flight crews have felt unprepared to diagnose engine malfunctions that have occurred.turbo machinery in the engine uses energy stored chemically as fuel. The basic principle of the airplane turbine engine is identical to any and all engines that extract energy from chemical fuel. The basic 4 steps for any internal combustion engine are:
) Intake of air (and possibly fuel).
) Compression of the air (and possibly fuel).
) Combustion, where fuel is injected (if it was not drawn in with the intake air) and burned to convert the stored energy.
) Expansion and exhaust, where the converted energy is put to use.can be found some damages of the aircraft engine caused by overheating, birds strike, or other reasons.
Damages Caused by Overheating in Engines
220 Degrees
ТЗ When the engine reaches just above 220 degrees, combustion of the gasoline can occur in areas other than just in the combustion chamber; this is known as detonation. This deton...
