Lateral Autonomous Performance Maximization of Tactical Unmanned Aerial Vehicles by Integrated Passive and Active Morphing

Abstract

Abstract-In this conference article, combined passive and active morphing approach is applied on tactical unmanned aerial vehicles (TUAVs) for autonomous flight performance maximization. For this intention lateral dynamic modeling of TUAVs manufactured in Erciyes University, Faculty of Aeronautics and Astronautics, Model Aircraft Laboratory is investigated in order to obtain lateral statespace model and a simulation model. Our manufactured TUAV is named as ZANKA-III which has weight of 50 kg, range of around 3000 km, endurance of around 28 hour, and ceiling altitude of around 12500 m. Von-Karman turbulence modeling is applied in order to capture atmospheric turbulence in lateral simulation environment. A stochastic optimization method called as simultaneous perturbation stochastic approximation (i.e. SPSA) is used in order to get optimum dimensions morphing parameters (i.e. extension ratios of wingspan and tailspan, assembly positions of wing and tailplane to fuselage).

Investigation of the Effect of Differential Morphing on Forward Flight by Using PID Algorithm in Quadrotors

“…As a control algorithm, they used proportional integral derivative (PID). T. Oktay and S. Coban [7] applied active and passive morphing for lateral movement on TUAV. They created the TUAV model in Matlab / Simulink environment.…”

Combined active flow and flight control systems design for morphing unmanned aerial vehicles

“…There is a common reality that for fixed-wing aircraft, lateral and longitudinal motions are strongly uncoupled in the literature. 16,17 In previous studies, 18,19 this situation is taken into account and both motions are evaluated independently from each other. First time, in this article this drawback is regarded, and longitudinal and lateral autopilot systems are simultaneously designed in order to obtain best magnitudes of blower position and morphing parameters and so combined design approach is also regarded for the first time in the literature.…”

Determination of the Optimum Flight Parameters for Maximum Range and Minimum Power Requirement of a Vertical Take-Off and Landing UAV

“…Bu sorunu ortadan kaldırmak için dikey iniş kalkış yapabilen İHA'lar geliştirilmiştir. İHA'ların uçuş performansını arttırmak için birçok çalışma yapılmıştır [2][3][4][5][6][7][8][9]. Dikey iniş kalkış yapabilen (VTOL) İHA bir quadrotor helikopterin hassas vurgulu yeteneklerini ve sabit kanatlı bir uçağın yüksek menzilini, dayanıklılığını ve yüksek seyir hızı özelliklerini birleştirir [10].…”
