    Making the most of Simulation Control Logic Some simulation models have some degree of complex conditional statements within their routing logic. SIMUL8 includes a programmable language that allows the user to develop logical statements and use various commands. Department of Electrical, Electronic, Telecommunications Engineering and Naval Architecture Design by Optimization of a is applied for the design of a Controllable Pitch (CP) propeller at different pitch settings, with the aim of reducing the cavitating phenomena and, consequently, the.   Abstract. Propellers for ships can be distinguished into two main types: fixed pitch propeller and controllable pitch propeller (CPP). The CPP design is an alternative for improved efficiency, especially in the need of a wide range of thrust and load levels, while maintaining an optimum shaft speed, as in the case of diesel or gas : L. S. Araujo, M. C. Mendes, L. H. de Almeida, M. S. Dutra, D. Cardoso. Simulation is generally referred to as computer simulation, which simulates the operation of a manufacturing system. A computer simulation or a computer model is a computer program which attempts to simulate an abstract model of a particular system. Computer simulation was developed hand-in-hand with the rapid growth of the.

A propeller is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral, that when rotated performs an action which is similar to Archimedes' transforms rotational power into linear thrust by acting upon a working fluid such as water or air. The rotational motion of the blades is converted into thrust by creating a pressure difference.

Also, Martelli () presented a propulsion control. a typical simulation application will have both controllable and uncontrollable (environmental) factors, which should be handled differently.

In these applications the aim is to manipulate the controllable factors so that the system is insensitive (robust) to changes in the uncontrollable factors. As described by Kleijnen () and Sanchez.

Aircraft Control and Simulation: Dynamics, Controls Design, and Autonomous Systems, Third Edition is a comprehensive guide to aircraft control and simulation.

This updated text covers flight control systems, flight dynamics, aircraft modeling, and flight simulation from both classical design and modern perspectives, as Cited by:   In this paper, we are going to design an aircraft autopilot to control the pitch angle by apply the state-space controller design technique.

In particular, we will attempt to place the closed-loop poles of the system by designing a controller that calculates its control based on the state of the system.

controllable pitch propeller systems are generally designed and constructed to fail in the “as is” position, in hydraulic CPP systems, the actual blade pitch may change. In this case the vessel was making considerable sternway. This was not a unique occurrence.

At speeds less than 12 knots, instead of increasing shaft rpm, the pitch on the blades is changed to take a larger or smaller bite of water.

When backing down, the blades are reversed to bite back into the water, giving an immediate slowing effect. U.S. NAVY CONTROLLABLE PITCH PROPELLER PROGRAMS.

Another thing that affects the simulation speed is the quality setting. If you suffer from slow simulations, try to adjust the "Solid buffer resolution" setting in the program settings.

A lower quality setting will give you faster simulations. The research described in this paper was carried out to predict hydrodynamic and frictional forces of controllable pitch propeller (CPP) that bring about fretting problems in a blade bearing.

The governing equations are Reynolds-averaged Navier-Stokes (RANS) and are solved by OpenFOAM solver for hydrodynamic forces behind the ship&#x;s wake.

The smaller of the two ferries which have been modeled is a multideck, single-ended type which is propelled by twin controllable-pitch propellers and has twin rudders and bow thrusters.

It is approximately meters (about feet) in length and has a. In conducting a simulation experiment the analyst selects the controllable inputs (decisions) while uncontrollable probabilistic inputs are generated randomly.

The simulation model uses these inputs, the equations and the logical relationships of the model to compute the values of the outputs (performance criteria such as cost, revenue, etc.).

It is a method that can be used to predict how a system will operate given certain choices for controllable inputs and randomly generated values for the probabilistic inputs.

Construction diagram of controllable pitch propeller A controllable pitch propeller is made up of a boss with separate blades mounted into it. An internal mechanism enables the blades to be moved simultaneously through an arc to change the pitch angle and therefore the pitch.

A typical arrangement is shown in Figure below. sand the collective pitch angle 0 at the helicopter freestream Mach number of M=without the inclusion of a cyclic pitch motion.

An additional ight case with cyclic pitch motion was examined at s= 0 and = 0. Each simulation took roughly 48 hours with a total of 96 parallel cores to compute. Experimental. About finding the pitch/rpm balance: best efficiency in a diesel is often found slightly above max torque rpm's.

This fact is used to reduce the amount of guesswork needed to find the optimum setting. So, with low to medium pitch setting, give her throttle to slightly above max torque rpm, then adjust pitch until you have the speed you want.

Several simulation studies on pitch channel autopilot of a launch vehicle considering various uncertainties, input-output disturbances and noise show the ability of the proposed controller. The rest of the paper is organized as follows.
