© 2017, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.Guided munitions are air-to-air or air-to-surface weapons which have enhanced target hit capabilities with laser seekers or similar guidance utilities. The additional components enhance the target hit capability of the munition significantly but they bring along some aerodynamic challenges as well. The cross-coupled interactions are triggered with the sharp maneuvers and the stabilization of the roll channel is aggravated consequently. The decoupled aerodynamics assumption which is put forward for linear controller design holds no more and a significant amount of roll angle is induced with the presence of angle of attack on the munition. The dynamic interferences in nonlinear regions of the flight envelope, leads the studies on control of guided munitions to search for adaptive solutions. This paper presents an adaptive roll control scheme for guided munitions. The control algorithm includes a concurrent learning model reference adaptive controller (CL-MRAC) with state independent uncertainty parameterization.

Adaptive model predictive control of uncertain systems with input constraints
Yayla, Metehan; Kutay, Ali Türker (2017-01-01)
© 2017, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.This paper introduces a new hybrid adaptive model predictive control approach to control of uncertain dynamical systems where the matched uncertainty can be linearly parameterized by known basis functions. Introduced control framework respects the actuator position limit and actuator rate limit. Initially, an integration method in adaptive control is employed to identify the matched uncertainty in conjunction with Pseu...
High strain rate material characterization of Al 7075-T651 by modified Taylor impact test and velocity interferometry
Kesemen, Latif; Kayran, Altan (2017-01-01)
© 2017, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.Metallic materials in aerospace structures are exposed to impact loading depending on their usage area. High strain rate material characterization of metallic materials is very crucial to properly prepare finite element models to be used in impact loading situations. Aluminum alloys are widely used in aerospace structures in variety of areas. Johnson-Cook material model is a suitable material model to represent the beh...
Extended kalman filter based robust altitude controller for sea skimming missiles
Dülgar, Özgün; Gezer, Rüştü Berk; Kutay, Ali Türker (2016-01-01)
© 2016, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.A sea skimming missile is needed to be flown above mean sea level as low as it can, in order to decrease detectability; so that, survivability of the missile against counter attacks of the target ships is maximized. On the other hand, flying at very low height is a tough task under disturbances due to sea waves and measurement errors of various sensors used in height control loop. Thus, a robust altitude control system...
Modification of the extended messinger model for mixed phase icing and industrial applications with TAICE
Ayan, Erdem; Özgen, Serkan (2017-01-01)
© 2017, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.Computational studies have been performed in order to predict mixed phase ice accretion on aircraft components. In-house developed TAICE tool has been used in this study. Previously, TAICE was already validated for icing cases due to water droplets only. In addition, in the framework of High Altitude Ice Crystals (HAIC) FP7 European project, mixed phase ice accretion prediction capability has been added to TAICE. Up to...
Analysis of effects of different diffusion models in hypersonic flow regimes
Gur, H. Berk; Eyi, Sinan (2017-01-01)
© 2017, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.Hypersonic flows become popular due to its use in space explorations and military applications. It occurs normally, when a space craft re-enter to the atmosphere. Space crafts are exposed to high temperatures and high pressures because of Earth’s atmosphere and gravity. In addition in high temperatures, gases tend to react with each other. These reactions also have effects on space craft’s surface. In order to calculat...
