Maryland Delaware Rocketry
Association Inc.(MDRA)
| Liberty has flown. MDRA's Liberty Project was launched Saturday May 15, 2004 |
MDRA Group Project
Purpose:
To establish High Power Rocketry firsts by successfully
and safely launching
the largest rocket this side of the Mississippi. This will not be a Tripoli
Sanctioned
Launch. This rocket is an independent, privately sponsored project.
Requirements:
Vehicle weight in excess of 600 pounds. This should be a first.
Launch vehicle from Higgs Farm in Price, Maryland
Recover vehicle in two-stage recover configuration.
Drogue at apogee and mains around 2500 feet.
Nose cone will be recovered under it's own chute. This should be a first
Include onboard video and possibly ATV, Amateur Television.
This has been done before, but it should be included in the project.
Design:
Due to the size of this project I had originally envisioned looking at
and evaluating
designs from anyone in the group who wanted to submit one. The more
I thought
about it though the less inclined to I was to go that route. Because
I am providing
the tube and many of the components that will be integrated in the
rocket I made
my first command decision. I will design
the basic rocket. The design will be
original and will not be a scale of any existing rockets.The reason I am
proceeding
down this path is that I want to avoid any in fighting concerning the design.
I came
to realize that there were not many safe options to go
with on a project of this
magnitude. The only thing to argue about is the shape of the fins and I
want what
ever will give the rocket the most stability off the tower. As information
concerning
the motor is becoming available, the rocket and the weight associated with
it will
be designed around the motor. My goal is to build the rocket
as tall as possible.
The limitation is the weight of the airframe. The fiberglass tube weighs
between 25
and 30 pounds per foot. I want to keep the lift
off weight to about 600 pounds.
Presently there is a design that looks like a big Mini Magg. This design
will suit our
purposes of launching a safe, recoverable vehicle. Though it appears that
we may
be able to increase the length of the airframe with little penalty on performance
and
altitude. The rocket will be basically 4 fins and a nose cone.
Participants:
This project is open to all members of The Maryland Delaware Rocketry Association.
However in the interest of consolidating time, money and effort
I will be the Project
Manager. As the Project Manager I will coordinate all activities related
to the project.
I also have some specific people in mind to head up certain aspects
of the project.
In the next couple of weeks I will be contacting various people to act
as team leaders
to head up the many facets of construction and flight preparation that
will need to take
place. I believe that it will be in our interest to put Level 3
members in some of the
critical aspects of the project, as they already have big rocket experience.
Once they
agree their names and responsibilities will be posted. There are many people
in the
club that possess a great deal of skill and expertise in one or more of
the following
areas. Take a look at the list and see where you would like to help out.
Even if you
do not feel 100% qualified in an area, this may be a good opportunity to
gain that
knowledge.
Nose Cone
Construction:
Build a 24" diameter X 8' long Nose Cone. Dave Bullis to build the rough
Nose Cone, Bob Utley to finish, Neil McGilvray to provide Coupler.
Sanding
and Finishing the Air Frame Tubes:
Jeff Potter to head this up. We will need lots of help
with this portion of the project. We want it to be a showpiece.
Painting:
A project all in it self. The finished rocket will stand about 23' to 25'
tall. This is going
to take lots paint.
Assembly
of the rocket:
This area may need to broken down into smaller groups. I want Lester Sherman
to build the fins, centering rings and bulk plates at a minimum. Assembly
of these
components should be a group activity.
Electronics
and recovery:
Fred Wallace to head this up. This will be a small group, to be determined.
Written
Documentation:
I will be doing some of this and could use help.
Photo and
Video Documentation:
Open to all. This project is designed to be on the cover of Extreme
Rocketry
and High Power, (if they will have us).
Web Documentation:
You busy Bob??
Tower Construction:
Dave Bullis will be heading this up.
Transportation:
Someone has to move this beast.
Media coverage:
This should be on television.
Treasurer:
Does anyone know how to spell Dave Weber's name? I think that all interested
people
should start by contributing $50.00. This will give us some working capital.
I hope that
among the members we can keep the costs down but I don't want to sacrifice
quality
for cost. We have one chance to show the world that we can make this work.
Let's
do it right!
Tee Shirts:
We have to have shirts to commemorate the event and I am sure we can supplement
the costs by selling them.
This is the first pass at formal
documentation for the project so bear with me. Success will be a function
of many people working in the same
direction for the same goal. The real reason that we are doing this is
because it will be cool. Fun is the
main objective here after safety. Safety is number one and the rest is
details.
Stay tuned.
