Florida Legislative Intent: House Bill
1237
The Legislature finds that diversifying this state's
economy requires a focus on building a growing
base of high-wage jobs and on nurturing those
technologies and clusters that will be the
foundation of Florida's growing economic
diversity and prosperity.
“Growing Florida’s economy through the space
and aerospace industries is critical to the state’s
long-term prosperity.”
Governor Jeb Bush’s remarks at the first
meeting of the new Space Florida Board of
Directors - July 10, 2006
Florida Space Grant Consortium
“….Florida must take a more substantial role in
the intellectual activity surrounding space
missions……. scientists, engineers and industry
partners must play a more central and
prominent role in future spacecraft missions, and
to achieve that goal, the State of Florida must
invest in both the engineering technology and in
the science of space missions.”
Dr. Stanley Dermott, Chair of Astronomy at UF,

ESMD Competition – Hybrid Rockets
Sponsors:
• Florida Space Grant Consortium
• Florida Space Institute
• North East Florida Association of
Rocketry (NEFAR)
Participating Teams:

Hybrid Rocket Competition
• The objective of the competition was to design and
build a hybrid powered rocket.
• There were two categories of competition to choose
from; the first would be to reach the maximum
altitude and the second would be to fly the rocket
closest to 2000 feet in altitude.
• Competition Rules:
 The rocket can be scratch built or from a kit.
 The engine must be a hybrid motor rated “G”
or from a lower class
 Points awarded for the flight and engineering
notebook

Altitude Determination
Altimeters
A recording barometric altimeter must be used to record data for
competition.
Determining Actual Altitude
The actual flight profile will be determined by the competition judges.
The graph or other flight profile display provided by a recording device
will be examined for accuracy.
Other altimeters
Altimeters with altitude sensors other than barometric sensors, such as
accelerometers or magnetic apogee detection, may be used to deploy
the recovery systems. However, they are prohibited from use in
determining the actual altitude.
Recovery System Deployment
Motor delay recovery system deployment is allowed.
Motor Class Total Impulse
G or less: 160 Newton-seconds or less

ESMD Senior Design Class
AASPRIN
1. The primary purpose of the research was to
design a satellite, named AASPRIN, which
will rendezvous with Apophis and precisely
determine its orbit. This knowledge of
Apophis' orbit would make possible more
accurate estimations of any collision threat
posed to Earth.

2. The secondary mission was to collect scientific
data concerning the physical properties of
Apophis. Data on Apophis’ properties such
as absolute magnitude, tri-axial body
dimensions, gravitational mass, bulk density,
rotational period, and spectral type, will be
required if a deflection design is necessary

Experimental Investigation of Slosh Dynamics in Low Gravity
•
The NASA Kennedy Launch Services
Program (LSP) has recently received funding
to conduct a series of never before
investigated low gravity rocket propellant
slosh dynamics experiments.
•
These experiments will be flown on a special
KC-135 aircraft to simulate the gravitational
conditions relevant to the upper-stages of
launch vehicles, and the collected data will be
used to develop improved sloshing and
thermodynamics models to enhance the
LSP’s Independent Verification and
Validation (IV&V) capabilities for all future
ESMD Senior Design Class
Experimental Investigation of Slosh Dynamics in Low Gravity
•
The overall goal of the student project is to design a
sub-scale slosh experiment, develop an associated data
acquisition and reduction system, and to prepare the
data for suitable comparison to a computational fluid
dynamics (CFD) model that will be completed as a
parallel effort on the same research contract.
•
Specific tasks of the project are:
 Literature review
 Design of a scaled propellant
tank
 Accelerometer and associated
instrumentation selection
 Development of data reduction
simulation
 Integration of Sierra Lobo, Inc.’s
Cryo-Tracker® tape with tank

OVERVIEW: MOTIVATION
• During LEO → GEO, stage coasts for several hours
• Engine must re-start at end of coast for insertion

Potential Senior Design Topics
OVERVIEW: WHAT CAN HAPPEN INSIDE TANKS?
• Stage exposed to solar heating
• Propellant T&P must be within
narrow range for engine operation
– If propellants outside range engine
may not restart!
– Orbit cannot be circularized!

WHAT IS IMPACT OF BBQ ROLL ROTATION?
Shape at g/g0=1, w~850º/sec
Typical rotation rate, w~1º/sec
• Does 1º/sec matter?
• Not at g/g0=1 but coast at g/g0~10-4 → significant dishing effect

This design course involved a discussion of
the component systems of a spacecraft and
typical mission's requirements.
The operation and character of different
spacecraft hardware were presented, as well
as typical mission time lines from early
conception to final operations.
The students in this course participated in a
pico-satellite design competition
