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.
The air impacts dynamic pressure on the aircraft, the faster the plane, the higher this pressure—up to the design limitations. What causes structural failure when the aircraft is merely flown fast? High speed induces vibrations, flutters , etc., all would likely cause loss of control and/or structural damage/failure.
• When an airplane stalls at a higher indicated airspeed due to excessive maneuvering loads. • Airplane stall speed increases in proportion to the square root of the load factor.
The important findings of the study are that the risk of having a weight and balance related accident with cargo flights is 8.5 times higher than with passenger flights; that there are various factors involved in weight and balance accidents/incidents such as errors in the load sheet, shifting of cargo, incorrect loading etc.; and that automatic...
To "feel" the aircraft response through the flight controls as being "heavier or lighter" than anticipated at take-off can result from a weight & balance inaccuracy. In fact, when the CG is out of the operational limits, the safety consequences can be far more critical than just a strange feeling.
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.
28 cze 2015 · Causes include old wiring and frayed insulation, failed or overheated avionics or a short circuit. Once detected, the pilot should identify the faulty circuit by checking fuses and circuit breakers. If an open circuit breaker is hot, don’t reset it—it tripped for a reason.
