Identifying and explaining the factors affecting the design of safe structures of Nahaja fighter aircraft with physical defense approach

Objective: By using effective factors in the design of safe structures, it is possible to create a suitable level of protection for Nahaja fighter planes in the environment of future battles; in such a way that they are hidden and safe from detection and damage sensors and advanced weapons of the enemy. Therefore, in this research, the factors affecting the design of the safe structures of Nahaja fighter planes have been identified and explained with the approach of physical defense.Method: The type of applied-developmental research is a descriptive-case study method with a mixed approach. The statistical population of the study included all experts and experts of the military apparatus who are familiar with the topics of passive defense. Using purposive sampling method, 30 people were selected as the sample. Data collection tools included interviews, questionnaires, and standard documents whose validity was confirmed by content validity and their reliability by Cronbach's alpha.Findings: Based on the data analysis, the most influential components of the independent variable are location; Related to territorial planning with an average of 4/533 and a variance of 0/315, and the lowest impact related to technical and engineering factors with an average of 4/1 and a variance of 0.83, the highest impact of independent variable components of architectural principles and techniques related to interior architecture design with an average of 47 4.4 and variance 0.38 and the lowest effect related to multi-purpose use with an average of 3.13 and variance 1.18, the highest effect of the component in the field of using electrical facilities with an average of 4.43 and variance 0.57 and the lowest effect related to using the fire alarm system with a mean of 4.33 and a variance of 0.56.Conclusion: Failure to observe the factors affecting the design of safe structures of Nahaja fighter jets with the physical defense approach, in addition to the vulnerability of these places during the threat, leads to irreparable damage
