  • Vibration analysis of FGM cylindrical shells under various boundary conditions 

    ansari, reza؛ Darvizeh, M.؛ Hemmatnezhad, Milad (Iranian Aerospace Society, 2008-07-01)
    In this paper, a unified analytical approach is proposed to investigate vibrational behavior of functionally graded shells. Theoretical formulation is established based on Sanders’ thin shell theory. The modal forms are ...

  • VISCOUS NUTATION DAMPER, MODELING AND ANALYSIS 

    Abedi, hasan؛ Sohrabian, M. (Iranian Aerospace Society, 2008-07-01)
    In some aerospace vehicles, the tracking sensors which act in a tracking loop as stabilizer are mounted on a two degree of freedom gyro. The gyro must align its rotor axis with the line of sight in order to remove tracking ...

  • Aircraft Visual Identification by Neural Networks 

    saghafi, fariborz؛ Khansari Zadeh, Seyed Mohammad (Iranian Aerospace Society, 2008-07-01)
    In the present paper, an efficient method for three dimensional aircraft pattern recognition is introduced. In this method, a set of simple area based features extracted from silhouette of aerial vehicles are used to ...

  • Gravity-Compensated Robust Control for Micro-Macro Space Manipulators During a Rest to Rest Maneuver 

    Sadigh, Mohammad J.؛ Salehi, Ali (Iranian Aerospace Society, 2008-07-01)
    Many space applications require robotic manipulators which have large workspace and are capable of precise motion. Micro-macro manipulators are considered as the best solution to this demand. Such systems consist of a long ...

  • OPTIMUM DESIGN OF FILAMENT–WOUND LAMINATED CONICAL SHELLS FOR BUCKLING USING THE PENALTY FUNCTION 

    Kabir, Mohammad Zaman؛ Rojhani, Arash (Iranian Aerospace Society, 2008-07-01)
    Optimum laminate configuration for minimum weight of filament–wound laminated conical shells subject to buckling load constraint is investigated. In the case of a laminated conical shell the thickness and the ply orientation ...

  • Incremental Predictive Command of Velocity to Be Gained Guidance Method 

    Ghahramani, Nematollah؛ Naghash, Abolqasem؛ Towhidkhah, Farzad (Iranian Aerospace Society, 2008-07-01)
    In this paper, a new incremental predictive guidance method based on implicit form of velocity to be gained algorithm is proposed. In this approach, the generalized incremental predictive control (GIPC) approach is applied ...
