The focus of this article is the pressure-control problem of gas generators employed in variable-speed rockets. The ability to change the speed during operation enables these rockets to adjust to the demands of different types of maneuvers and varying flight conditions. As a result, speed-controllable rockets provide a dramatic advantage over their alternatives with fixed speed profiles. In throttleable ducted rockets, speed variation is achieved by changing the fuel flow rate (throttleability), which requires a careful controller design. The article provides a detailed review of the current state of rocket propulsion control and the main challenges in the field. A controller (which contains a unique combination of traits such as fast adaptation, delay compensation, and provision of a smooth response) is introduced as a solution to the pressure control problem in air-breathing rocket propulsion. The superior performance of the controller, compared to existing alternatives, is demonstrated through experimental tests, using a test setup provided by Roketsan, Inc.

Adjoint based optimization of supersonic converging diverging nozzle Yerlikaya, Berkan; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2019) The nozzle produces the required thrust for the vehicle in an aircraft or rocket engine by expanding and accelerating the exhaust gas. In this study, the thrust of a supersonic converging-diverging nozzle is optimized by using SU2 software and the adjoint-based optimization tool. During the design optimization procedure, the inlet area, the exit area and the length of the nozzle are kept constant. The main objective is to obtain the maximum thrust within the geometric limitations. In order to maximize the t...
Selective Harmonic Elimination for Variable Frequency Traction Motor Drives Using Harris Hawks Optimization Nalçacı, Gamze; Yildirim, Dogan; ÇADIRCI, IŞIK; Ermiş, Muammer (2022-07-01) In this article, Harris hawks' optimization (HHO) for selective harmonic elimination method (SHEM) of a voltage source inverter has been applied to a traction motor drive for light rail transportation. The main objective of SHEM's pulsewidth modulation (PWM) strategy is to remove the low-order harmonics by solving nonlinear equations while satisfying the required fundamental component's magnitude. The HHO applied in this article to a two-level, three-phase inverter aims at solving the associated nonlinear e...
Energy and Time Optimal Autopilot for Electric Vehicles Performing Ackerman Cornering Ahiska, Kenan; Özgören, Mustafa Kemal; Leblebicioğlu, Mehmet Kemal (2022-03-01) This paper studies energy and time optimality of electric vehicles during constant Ackerman steering along a quad-circle, and proposes an autopilot assimilating the optimal results. The energy and time optimal solutions satisfying the steering and battery limitations are generated and a Pareto-front analysis is carried out with multi-objective optimization using NSGA-II algorithm. In the autopilot design, the indicators for the energy and time optimality performances are merged in a vehicle status vector. A...
Non-local stabilization of nonlinear systems using switching manifolds Banks, SP; Salamci, MU; McCaffrey, D (2000-02-01) The stabilization of nonlinear systems is considered by reducing the problem to a lower dimensional switching manifold which is made globally attracting. The switching manifold is designed using the stable manifold of the unforced system. The technique is first developed in local case and then in the global situation of nonlinear vector fields on manifolds. The method generalizes the standard Lyapunov approach.
High-speed jet flows over spillway aerators Kokpinar, MA; Göğüş, Mustafa (2002-12-01) The characteristics of high-speed air-entrained jet flow over a spillway aerator were investigated using experimental data. Three different ramp designs (as well as the case of no ramp) were tested in a channel where the bed slope was adjusted to 0, 0.17, and 0.57, respectively. The effects of aerator geometry and flow condition on the air-entrainment process within the water jet and on the pressure fluctuations in the impact region are the main focus of the investigation. An extensive data analysis was per...
