As a Civil Engineer myself, I just have to chime in.
 
Master Builders does not make concrete, they make concrete better. They make chemicals (called admixtures) that are added to concrete as it is mixed at the batch plant. Some of these chemicals may also be added to the transit mixer (cement truck as you non-Engineers call it) after it arrives at the job site. These chemicals can be used to speed up the time it takes concrete to cure (no it does not dry, the water in it chemically bonds with the cement in a fashion not dissimilar to 2-part epoxy), slow down the time it takes to cure, improve the fluidity of the mix (so that less water can be used but the stuff still flows), increase the amount of entrained air (very important for sidewalks and driveways in climates such as ours to prevent surface distresses), and a multitude of other things.
 
I'm sure Fred will let us know all the other things Master Builders does, these are just the ones I am familiar with.
 
BTW, I was a member of the Akron U. Drinking Team (we just called ourselves the Concrete Canoe Team in public). We did not use Sonotubes, plastic hose fits in the mouth much better! Oh, you mean to make the canoe? Shucks, we had a mold.

Mark Recktenwald <m_reckt@...>
 

Paul R. Bixler wrote:

<snip> I guess no experts on adding new files into the motor
file with the Wrasp software.
I am not a wRASP expert, just a frequent user and tinkerer (hacker?).
This is a lengthy reply that I contemplated sending only to Paul and
not to the group, but felt that others here may like to see it.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

First, some general notes on wRASP engine database files:

1. You can have more than one engine database file, but only one at a
time can be loaded into wRASP. It is best to place all of the engine
database files in the same directory as all of the other wRASP files.
You can load a different engine database file from the menu: "File",
"Motor Data File...".

2. The copy of wRASP v2.0 that I downloaded on 7/31/1998 was distributed
with two data files: Mick.eng (dated 7/22/1996) and Rasp.eng (dated
1/22/1997).

3. The copy of wRASP v2.1- that I downloaded on 6/29/1999 was
distributed with two data files: Nar_0298.eng and Rasp.eng, both
dated 6/28/1998. As of 1/15/2001, the wRASP site
(http://www.wrasp.com) had a slightly newer version of Rasp.eng
(dated 1/24/1999) at http://www.wrasp.com/data.html.

4. On 11/28/2000 I downloaded a new data file from the ThrustCurve.org
site: All.eng. This file has a date of 8/23/2000 and appears to
contain only Tripoli-certified high-power motors. As of 1/15/2001,
this same file was still available on ThrustCurve.org.

5. The data for the D11, F20, and G35 are in Nar_0298.eng.

6. The data for the F20 and G35 are also in Rasp.eng for v2.1-.

7. The data for the F20, F23, G35, and G38 motors are all in a file on a
site maintained by Jeff Davenport (JDCluster). Go to
http://www.users.nac.net/jdcluster/download.htm and get
Motorfiles.zip. That ZIP file contains a file named 2ap.eng with a
date of 12/14/1999. I had problems getting that file to run in wRASP
v2.1- on a Windows 98 machine (the only test I ran so far).

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Here on some notes on the structure of the wRASP engine database files:

1. The help file included with wRASP v2.0 contains the following:

Databases
wRASP stores its data in several files that are separate from the
program itself. These data files are in ASCII format which means
they may be changed with a text editor and used with wRASP without
recompiling the program or getting a new version.

WARNING: You are on your own if you change these files and then
run wRASP with them!

Motor (Engine) Database
wRASP uses the same basic motor database (RASP.ENG) that was
supplied with Mark Johnsons RASP v2.5b which included some Aerotech
RMS motor entries that were converted from the Rogers Aeroscience
(RAS) ALT4 motor database which was so graciously donated by the
RAS folks to the CompuServe MODELNET Library (LIB 8). A couple of
minor additions were made but the content and format of the ASCII
file is the same. This file can be loaded into a text editor and
modified to suit the rocketeer. wRASP loads this file by default
but allows the loading of a different file through the File menu
item, Motor Data File....

NOTE: The term motor and engine are used by rocketeers to
describe the whoosh generator used to propel their rockets.

The format of the ASCII file is:
; semi-colon in the first column followed by text is a comment and is not
processed.
type diameter length delays propellant_wt total_wt mfg notes
time1 thrust1
time2 thrust2
...
timeN thrustN
;next motor

Where:
type specifies the motor designation, like A8.
diameter specifies the motor diameter in millimeters, like 18.
length specifies the motor length in millimeters, like 70.
delays specifies the ejection delay list separated by dashes, like 0-3-5.
propellant_wt specifies the propellant weight in kilograms, like 0.00330.
total_wt specifies the total motor weight in kilograms, like 0.0162.
mfg specifies the motor manufacturer, like E for Estes, AT for Aerotech,
etc.
notes are additional comments, if needed.
time1/thrust1 define the thrust curve for the motor (0 thrust at time 0 is
assumed):
timeN specifies the time in seconds for point N.
thrustN specifies the thrust in Newtons for point N.

NOTE: There is not a final carriage return character at the end
of this file.

The table entry for the Estes A8 motor would then be:
A8 18 70 0-3-5 0.00330 0.0162 E
0.150 8.300
0.180 9.600
0.200 9.700
0.224 9.600
0.229 8.900
0.250 6.200
0.314 3.970
0.335 3.850
0.415 3.750
0.450 0.000
;

2. The following appears in the documentation notes at the top of
Nar_0298.eng:

; NAR S&T Motor Test Data
; Available from NARTS (received 02/98)
; REQUIRES wRASP v2.1- to load properly.
;
; NOTE: heaviest motor of each type is used for basic mass.
;
; ALSO: Plugged motors use a delay of 37 as a space filler (and plug code).
;
; Basic format (linear measure in mm, mass in kg, time in sec, thrust in
N):
; designation diameter length delay-list propellant_mass total_mass
vendor
; 0.0 0.0 (assumed if not present)
; time thrust
; ...
; burn-time 0.0
;
; thrust Time-curve restrictions:
; DOS RASP89 and wRASP up to v1.6: 32 time/thrust entries (64 values) per
motor
; wRASP v1.61, v2.0 and v2.1BW: 64 time/thrust entries per motor
; wRASP v2.1: 16384 time/thrust entries for entire motor database (no
limit per motor)
;
; Chuck Gibke 25 June 1998
; CGibke@...
; http://ourworld.compuserve.com/homepages/CGibke/wrasp.htm
; http://www.geocities.com/TimesSquare/Alley/9118/wrasp.html

3. The whatsnew.txt included with wRASP v2.1- contains the following
line: "PLEASE NOTE that the NAR motor database WILL NOT run on any
version of wRASP prior to version 2.1-!"

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Here on some notes on editing the wRASP engine database files:

1. If you edit one of the existing database files, I would suggest
saving it with a new name to preserve the original.

2. The data files are plain text files (ASCII) with an extension of ENG.
They can be edited with any text file editor.

3. Most data files begin with a section of comment lines describing the
source(s) and the contributors.

4. A comment line begins with a semicolon (;). In its simplest form, a
comment line is nothing more than a semicolon on a line by itself.
Some authors have placed a space after the semicolon even if there is
no text after that. Some authors describe the source of the data for
each motor on this comment line. More than one comment line can be
used if needed to keep the comment from running off the edge of the
page when viewed. There may be a line length limit. To be safe, keep
the length of each comment line under 80 characters total (semicolon
and space included).

5. A comment line separates data for each different engine in the file.

6. For each engine, the first line of data contains seven elements.
6.1 Engine type (i.e.: A8, F50W, etc.)
6.2 Engine diameter in millimeters
6.3 Engine length in millimeters
6.4 Available delays separated by hyphens and no spaces (for an
Estes C6 it would be 0-3-5-7)
6.5 Weight of propellant in engine in Kilograms
6.6 Total weight of engine in Kilograms
6.7 Engine manufacturer or other notes
These seven elements must be separated by at least one space. It is
common to see them separated by three spaces. Although the v2.0 help
file indicates "notes" as an eighth element on this first line, I
have never seen an engine database file with notes separate from the
manufacturer. It is typical to see a propellant code or some
abbreviation for "single use" or "reload" appended to the
manufacturer abbreviation (i.e.: AT-RMS). The type and manufacturer
fields are what actually appear in the "Motor Type" list in the
"First Stage" Dialog Box that displays from the menu:
"Data", "Stage 1...".

7. For each engine, the remaining lines of data contain two elements
each.
7.1 Time in seconds
7.2 Thrust in Newtons
These two elements are coordinate points taken from the thrust curve.
These two elements must be separated by at least one space. It is
common to see three leading spaces in front of the first element and
three to five spaces between the two. For compatibility with DigiTrak
(an optional calculation function built into wRASP), do not input a
non-zero thrust value for time zero. If you have a non-zero initial
thrust value, enter it at a time of 0.000001 instead of zero. You can
enter "0.0 0.0" for the first time/thrust pair. The last time/thrust
pair must show a thrust of zero.

8. I will repeat a line from the help file for emphasis: "There is not a
final carriage return character at the end of this file." The file
can end with the last time/thrust pair for the last engine or with a
comment line, but again, do not put a carriage return at the end of
this last line.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Here is an example of the simplest form:

;
C6 18 70 0-3-5-7 0.0108 0.0222 E
0.054 2.0
0.107 8.0
0.155 13.3
0.181 13.3
0.196 10.5
0.214 8.5
0.25 7.5
0.268 6.5
0.339 6.0
0.446 5.65
1.393 5.65
1.45 0.0

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Here is the same data in a much more readable form, with documentation:

; C6 modified 8/11 to match NAR published delivered impulse,as tested 10/78
C6 18 70 0-3-5-7 0.0108 0.0222 E
0.054 2.000
0.107 8.000
0.155 13.300
0.181 13.300
0.196 10.500
0.214 8.500
0.250 7.500
0.268 6.500
0.339 6.000
0.446 5.650
1.393 5.650
1.450 0.000

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

See how padding the spaces helps spread out the data making it easier to
read? See how indenting the time/thrust pairs sets them apart and makes
the engine type stand out? This data also has padded zeros in the
time/thrust pairs to make their columns uniform.

You *can* vote often, only thing is, your subsequent votes cancel your

Yikes...saw "Superlube" and thought I was signed up for one of those "other"
E-Group communities.

Hey everyone, I went to the Superlube site and ordered an info packet
and a small sample, (Superlube is the stuff you get when you buy
Aerotech casings) they sent me a Superlube aerosol can, 2 3oz tubes,2
special grease pens (they look a little bit like pens)and a huge 400
gram canister of Superlube. This stuff is great for using on your o-
rings, hunting, household, everything. I will bring some for everbody
at the next meeting.

Thanks, Harry Weiss

Hi Paul,

I have a picture of the Viper, but the distance was a bit far. Go to the
MTMA E-Groups web page and look under files, it's under the MTMA Nov 24th.
launch section, one of the 99XXXXXX files.

Subject: [MTMA] WRasp software


I'm new at using the Rasp software and I wish to run a simulation with 3
motors that are not listed in the motor list. The D-11-P, the F20 and the
G35 which I have seen thrust curves posted on the web at thrustcurve.org.
Also the F-23 and the G-38, but I haven't been able to find a posted
thrustcurve from anybody but aerotech. How do you create a rasp file and put
it in the program? Anybody had experience with this?

Also my brother and I joined the launch the day after Thanksgiving and I
launched my Viper IV. We are the guys from Pittsburgh. One of the guys
said he got a good picture of it and was wondering how I might find that
picture which he said he would post somewhere.

Thanks

Paul
