PROP93
Joe McCarty
PROP93 is a "C" language
version
of PROPPC [1,2] that provides an input editor and both graphical and
printed
output. PROP93 performs wind turbine calculations only. The propeller
mode is
turned off. The rotor radius in PROPPC has been redefined as blade
length in
PROP93. The rotor radius in PROP93 consist of the sum of two terms,
blade
length and hub extension. With a hub extension of zero, PROP93 is
identical to
PROPPC. The hub extension term allows the client to model the effects
of hub
extension on an existing blade without having to redefine the blade
geometry. A
yaw angle has been added.
PROP93 will accept the old
PROPPC input
files as well as a new AEI input file. The AEI files rep;ace the
coefficients
of lift and drag (CL, CD) data with filenames. The CL, CD data are
stored in
separate files with AIR file extensions. The AEI files allow the client
to
easily change the airfoil at a blade station.
A mouse driven menu system
allows the
client to read input files (PROPPC or AEI), edit the input data, run
PROP code,
and produce graphical output. The input and output data can be viewed
on the screen,
sent to a printer or saved in a file. When the input data is saved to a
file,
that file can be used as an input file to PROP93.
PROP93 produces two styles
of graphs, X-Y
and color sector. The X-Y style of graph allows the selection of blade
station,
wind speed, tip speed ratio, or pitch angle for the X axis. The Y axis
parameter can be selected from the PROP output parameters.
