A simulation of the helicopter/ship dynamic interface has been developed and applied to simulate a UH-60A operating from an LHA class ship. Time accurate CFD solutions of the LHA airwake are interfaced with a flight dynamics simulation based on the GENHEL model. The flight dynamics model was updated to include improved inflow modeling and gust penetration effects of the ship airwake. An optimal control model of a human pilot was used to simulate pilot control activity for a specified approach trajectory. The pilot model was designed so that the tracking performance could be tuned based on a desired crossover frequency in each control axis. The model was used to predict pilot workload for shipboard approaches in two different wind-over-deck conditions. Although further validation is needed, preliminary results show that the simulation results in similar workload trends as recent flight test studies.

Simulation of helicopter shipboard launch and recovery with time-accurate airwakes
Lee, Dooyong; Sezer Uzol, Nilay; Horn, Joseph F.; Long, Lyle N. (2005-01-01)
A simulation of the helicopter/ship dynamic interface has been developed and applied to simulate a UH-60A operating from a landing helicopter assault (LHA) class ship. Steady and time-accurate inviscid computational-fluid-dynamics (CFD) simulations are performed over a full-scale LHA class ship using the parallel flow solver PUMA2 to predict the unsteady vortical ship airwake. Time-accurate CFD solutions of the LHA airwake are interfaced with a flight dynamics simulation based on the GENHEL model. The fligh...
Evaluation of rotorcraft system identification approaches
Kaymak, Serkan; Tekinalp, Ozan; Kutay, Ali Türker; Department of Aerospace Engineering (2013)
This thesis addresses rotorcraft system identification approaches and estimating the stability and control parameters for linear system identification of a helicopter in hover. Output error and least square methods are used for the system identification. Inputs of the system identification analysis are obtained from the nonlinear helicopter model written in FLIGHTLAB commercial software environment. A linear helicopter model is used for identification. For validation, results obtained from identified helico...
Real-time hardware-in-the-loop simulation of electrical machine systems using FPGAs
Üşenme, Serdar; Dilan, R.A.; Dölen, Melik; Koku, Ahmet Buğra (2009-11-18)
This study focuses on the development an integrated software and hardware platform that is capable of performing real-time simulation of dynamic systems, including electrical machinery, for the purpose of hardware-in-the-loop simulation (HILS). The system to be controlled is first defined using a block diagram editor. The defined model is then compiled and downloaded onto an FPGA (¿Field Programmable Gate Array¿) based hardware platform, which is to interface with the controller under test and carry out the...
Scalable computational steering system for vizualization of large scale CFD simulations
Tonkal, Ozan Çağrı; Pehlivan, Sercan; Sezer Uzol, Nilay; İşler, Veysi (2002-06-27)
A general-purpose computational steering system (POSSE) which can be coupled to any C/C++ simulation code, has been developed and tested with a 3-D Navier-Stokes flow solver (PUMA2). This paper illustrates how to use “computational steering” with PUMA2 to visualize CFD solutions while they are being computed, and even change the input data while it is running. In addition, the visualizations can be displayed using virtual reality facilities (such as CAVEs and RAVEs) to better understand the 3-D nature of th...
