1 kwi 2018 · Fuselage frames provide a significant contribution to the resistance to crash landings and dissipate a large portion of the kinetic energy of the aircraft. A number of experimental and analytical studies consider composite frames with various cross-sectional shapes.
New electric powerplant technolo-gies and the increased use of flammable fibre composite materials in aircraft structures have directed more attention to fire protection. Great effort was made in developing materials for improving the fire resistance of fibre composites.
Realities and related fallacy. WFP operations are very demanding, take place in difficult areas with little flight support, this in very dynamic environements and changing conditions. The laws of mechanics and aerodynamics governing the safe operation on an aircraft are fixed and inalterable.
The load and resistance factor design (LRFD) approach judiciously combines these two approaches by intensive calibration studies on loads and strength to result in structures that are efficient and reliable.
30 sie 2023 · The main objective of this paper is to analyze the typical failure features that aircraft polymer composite exhibit when they fail due to tension, compression, bending loading conditions, fatigue, impact loading and fire.
1 lis 2002 · The investigation of defects and failures in aircraft structures is, thus, of vital importance in preventing further incidents. This review discusses the common failure modes observed in aircraft structures, with examples drawn from case histories.
Loss of control can occur if the aircraft is loaded for flight in such way that it is outside of the flight envelope or is mis-trimmed because the actual loading of the aircraft is not as documented. Flight outside the flight envelope may also arise after take off because of in-flight load shift or fuel transfer effects.
