Software and Hardware Description of the Helicopter Motion Equations for VAX Computers.

摘要

The Human Factors Cockpit Research, Experimentation, and Workload (CREW) Simulator is a fixed base, generic helicopter simulator that provides the flexibility to explore state-of-the-art aircrew/display/control interaction. The CREW simulator involves four major components: the visual system, the graphics system, the data collection, and the flight equations. HEL uses the UH60 Blackhawk version of the standard kinematic equations for an aircraft (herein called HAC equations) when conducting experiments on the CREW simulator. The HAC equations were acquired from NASA Ames, in Mountain View, California, with the objective of simulating aerodynamic characteristics of a helicopter in a part-task simulator for human factors studies related to displays and controls. The HAC equations also allow us to simulate nap-of-the-earth (NOE) flight. This report describes the software design and the hardware configuration used to execute the HAC equations on a MicroVAX II VAXLab computer under the VMS operating system using VAX FORTRAN. The HAC equations are not described in detail in this report. For more detailed information, refer to McFarland (1975). The objective of this report is to provide internal documentation and also to provide a description of design for others desiring to implement these or similar equations of motion under the VAX/VMS (Virtual Address extension/Virtual Memory System) operating system in a real-time, manned interactive simulation.
