This article presents the detailed methodology developed for the vulnerability assessment of the military aircraft against fragmentation warhead. Vulnerability assessment methodology consists of calculation of the dispersion of the fragments, determination of the hit locations, penetration calculations and probability of kill calculations for the aircraft utilizing the fault tree established for the particular aircraft studied. Based on the developed methodology, vulnerability assessment and survivability analysis of a generic aircraft is performed for different predefined approach angles of the missile threat. For the measure of the vulnerability, mean volume of effectiveness of the warhead is proposed as the metric which is defined as the volume integral of the probability of kill distribution around the aircraft for different intercept directions of the missile. Through the case study, it is shown that mean volume of effectiveness can be used as the single measure of the overall vulnerability assessment of the aircraft. (C) 2017 Elsevier Masson SAS.

Analysis of Aircraft Survivability Against Fragmenting Warhead Threat
Konokman, Hüseyin Emrah; Kayran, Altan; KAYA, MUSTAFA (2014-01-17)
The article presents the methodology of the aircraft survivability analysis considering vulnerability of the aircraft against fragmenting warhead threat. The initial step of the survivability analysis against a fragmenting warhead threat is to position the target and the warhead in proper coordinate systems for the calculation of warhead-target engagement. Once the warhead detonates at a miss distance from the target, the motions of the fragments are calculated considering the drag and the gravity forces an...
Radar cross section reduction of cylindrical cavities using ray-tracing method
Sezgin, Yusuf; Dural Ünver, Mevlüde Gülbin; Department of Electrical and Electronics Engineering (2022-5-16)
Low observability technology, which aims to make it difficult to be detected, tracked, and hit by the enemy forces is one of the most critical technologies for 5th generation fighter aircraft. Low observability in Radio Frequency (RF) band is achieved by minimizing the Radar Cross Section (RCS) of the aircraft at specific angular zones and frequencies. RCS is a quantity related to the amount of reflection of the incoming electromagnetic wave by the aircraft and it is generated by different scattering mechan...
Flight control system design for an over actuated UAV against actuator failures
Işık, Sinem; Tekinalp, Ozan; Department of Aerospace Engineering (2010)
This thesis describes the automatic flight control systems designed for a conventional and an over actuated unmanned air vehicle (UAV). A nonlinear simulation model including the flight mechanics equations together with the interpolated nonlinear aerodynamics, environmental effects, mass-inertia properties, thrust calculations and actuator dynamics is created; trim and linearization codes are developed. Automatic flight control system of the conventional UAV is designed by using both classical and robust co...

In this study, a software that is utilized after the pre-design phase of the missile design is presented. This software consists of computational domain modeller and multi-block structured mesh generator. Geometrical design variables of the missile used in the software are based on Missile DATCOM and the presented software eliminates the time consumed between the preliminary design and the CFD analysis by automating the computational domain generation. In order to model the different orientations of the fin...
High-alpha flight maneuverability enhancement of a fighter aircraft using thrust-vectoring control
Atesoglu, Oezguer; Oezgoeren, M. Kemal (American Institute of Aeronautics and Astronautics (AIAA), 2007-09-01)
This study focuses on high-alpha flight maneuverability enhancement of a fighter-bomber aircraft for air combat superiority using thrust-vectoring control. Two basic air superiority maneuvers are studied as test cases, which are the Cobra maneuver with longitudinal motion and the Herbst maneuver with both longitudinal and lateral motions. The necessary mathematical models are built to describe the nonlinear 6-degree-of-freedom flight dynamics, the nonlinear aerodynamics, the engine, and the thrust-vectoring...
