A method for determining and reducing transport delays in the flight simulation environment

Smith, R. Marshall 24 October 2009 (has links)
This report will describe the process of transport delay measurement along several points in the signal path for piloted flight simulators. Measurements were made in both the frequency and time domain. A new method for collecting data from video transitions was designed and tested. The accuracy and ease of use of the new method was compared to the previous data collection method. The transport delays for individual pieces of equipment were determined as well as the delays associated with the computational flow of two vehicle math models. Hardware and software was then modified to significantly improve the overall transport delay characteristics of the simulation. / Master of Science

A Microcomputer Implementation of a Flight Simulator Visual Display System

Campbell, Jerry Wayne 01 July 1979 (has links) (PDF)
The use of computer graphics has brought about a universal means of depicting phenomena or solving engineering problems. The combination of graphic and computer skills offers a solution to a number of technical needs. One major area that computer graphics can be used is in the field of flight simulation. The software packages necessary to project three-dimensional scenes for flight training are not very common. The purpose of this paper is to generate the programs necessary to allow the pilot to observe a three-dimensional scene from any location and angle. The report discusses some of the basic aspects of computer graphics and presents specific computer software for projecting simulated flight landings at Herndon Airport in Orlando, Florida. The three-dimensional projections are calculated and displayed on the video monitor in the form of two-dimensional scenes. The Southwest Terminal System hardware was used as the interface to the video monitor. A description of the various operating parameters for simulated flight landings is presented. Included in the discussion are various pictorial representations of simulated landing approaches at Herndon Airport. Suggestions for additional work that could be undertaken in this research area concludes the report.

Digital Architecture for a Computer Based Imaging System

McIntosh, John Osborn 01 January 1979 (has links) (PDF)
There is a great need for a graphic simulation system used as a training device to take the place of actual flying. A good system will greatly reduce the cost of training men as well as cut down on casualties. Several systems have been tried and are now in use. Among them are two that are worthy of more study. These are the CCTV or model board and the digital systems. Both have several disadvantages that create a need for a new system. One such system is an optically based digitally processes system that combines the best features of two previous systems. This system uses charge-coupled-device memories that are digitally accessed by a microcomputer based system. The information from the CCD's is then processed and calculations are performed on it to transform it into a form that can be displayed on a cockpit-like screen. The system also allows for interaction between the pilot and itself.

A Projectile Subsystem in a Flight Simulation System

Hodson, Robert F. 01 January 1985 (has links) (PDF)
An overview of a flight simulation system is presented with a discussion of the system components and the interaction between functional units. The functions of each unit in the visual system are described. Specifically, the projectile subsystem portion of the visual system is presented in detail. A projectile subsystem executive structure is presented with capability of controlling projectile activation and deletion. Mathematical models for missiles with linear projected impact and proportional guidance are discussed. Ballistic projectile models with and without wind and drag considerations are developed. The mathematical equations for position and attitude calculations are given. Design considerations and implementation of algorithms are also presented with other system design trade-offs.

Analog Flight Simulators to Computer Interface

Selph, William J. 01 January 1984 (has links) (PDF)
The College of Engineering at the University of Central Florida has a flight simulator. This simulator was built as a stand-alone Instrument Flight Rules (IFR) training aid. The college has attempted on several occasions to augment this simulator system with a visual (out the cockpit view) simulation for the trainee pilot. Funding and resources have restricted or limited these enhancements to non real-time simulation. This project/thesis provides the university with part of the solution to accurate real time simulation. The simulated aircraft position and direction is acquired at 9 to 40 Hertz with 10-bit resolution. This data is made available in the ubiquitous RS-232C standard format. Thus any size computer can utilize the position and direction information for the simulated aircraft. With this element completed, a future project can utilize this information for time and motion studies or visual simulation.

Image Analysis and Improvement of a Point Light Source Visual Flight Simulator

Butrimas, Steve K. 01 January 1974 (has links) (PDF)
It has long been desired to simulate a non-preprogrammed controllable visual scene of the real world in a limited area for the purpose of training, in particular for aviation training. There presently exists a point light source projection system designed to accomplish this, however due to physical limitations, the display image, as compared to the corresponding real world scene which is being simulated, is somewhat distorted and limited. This point light source system is analyzed to determine the distortions and deviations from reality and methods are proposed to improve the display by minimizing the distortions and deviations.
