GENERAL INFORMATION AND INSTALLATION INSTRUCTIONS FOR:
FRASCA ROTARY ENGINE DESIGN PROGRAMS.  Version 98-2e.   Copyr., 1986-2000 by Joseph F. Frasca
!!! THE PROGRAMS WILL NOT FUNCTION OUTSIDE OF THE DIRECTORY (FOLDER) FRASCA. !!!
 Heat transfer program sections ares not included.
THE PROGRAM SECTIONS AND A BRIEF EXPLANATION OF THEIR PURPOSE.
RUN PROGRAMS SEQUENTIALLY.
1FRASCA This program is used to indicate the engine's basic physical characteristics.
2FRASCA  This program is used for partition design and acquisition of the cam-partition hydrodynamic interaction data. 
This program need not be run for the other programs to function properly; i.e. its data is not needed. 
3FRASCA  This program is used for the engine's basic compressor and operating environment data andmust be run before programs
4FRASCA and 5FRASCA.  Program 8FRASCA can be used immediately after this program for the graph of  its  data.
4FRASCA This program generates the basic thermodynamic data for the engine.  Program 8FRASCA can be used immediately after this program to graph the generated data. 
5FRASCA This program generates the engine's performance data.   Program 8FRASCA can be used immediately after this program to graph the generated data. 
6FRASCA  This program  determines the engines axial bearing loads, annular cavity circumferences, and the annular cavty  and its sections entroid radii and their location.
8FRASCA This progam can be used after the programs 3FRASCA, 4FRASCA, and 5FRASCA to graph the VVC  temperature and pressure data generated by the respective program sections.
CRFRASCA This programis used to generate the basic design data for an engine with a circular section annular cavity profile and the engine's VVC volume polynomials.

PROGRAM   6FRASCA
In single undulation and 4 cycle engines, ganging ( i.e. sharing the same power shaft) two rotors will cancel all bearing loading moments and power shaft  directed forces ( Z-axis forces) leaving only a force perpendicular to and rotating with the rotor shaft when:
the rotors'  power cycles are in phase, 
the rotors'  wave surfaces are directed towards the opposite ends of the power shaft,
the  X-Z  and Y-Z planes of the 2  rotor coordinate  systems are coincident, and
the positive X and Y axii  of the 2 rotor coordinate systems  point in the same direction.
