the study of flight vehicle structures reveals the importance of obtaining the most suitable accuracy compatible with construction. for this purpose, several experiments were conducted at the agard institute. in this paper the results of one such experiment performed on a sample airplane wing are presented. aircraft structural engineers use several methods to model these structures. specifing h...
This article proposes a new approach for centralized path planning of multiple aircraft in presence of the obstacle-laden environment under low flying rules. The problem considers as a unified nonlinear constraint optimization problem. The minimum time and control investigate as the cost functions and the maximum velocity and power consider as the constraints. The pseudospectral method applies ...
Public reliance on air transport industry as one of burgeoning factors of world economy is based on aviation safety. But the current challenge of aviation industry is the lax surveillance of safety standards by related governments which is basically due to illegal registration of aircraft. This article with reliance to the position of legal elements in achieving aviation safety has analyz...
Wing rock phenomenon is an undesired motion appears in high angles of attack where a rolling in the aircraft in positive and negative roll angles with specified amplitude and frequency is occurred. In this paper two adaptive controllers suggested to control the rolling dynamics under wing rock phenomenon for a delta wing aircraft with presence of disturbance. Disturbance was considered as unmat...
ice can form on aircraft surface at 0° c or colder temperatures when liquid water is present. this can happen both on the ground and at the flight levels of the aircraft. aircraft icing has not only an impact on flight safety but has also an economic impact. according to the report of research department of the faa (federal aviation administration), from 1982 to 2001, 13% of accidents due to ai...
Experience of the Armed Forces Institute of Pathology in aircraft accident investigation, 1956-1960.
In spite of technology developments in aviation industry, the world is beholder of every day air incidents and casualties in different –especially developing- countries. Experts' reports show that aircraft product defect is definitely making part of the cause. In this regard the liability of aircraft manufacturers in view of liability elements (negligence, product defect, causal relationship an...
