Florida Legislative Intent: House Bill Florida Legislative Intent: House Bill 12371237

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 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, invited editorial, Miami Herald, July 01, 2006 and Tampa Tribune, August 27, 2006

Florida Space Grant ConsortiumESMD Competition – Hybrid Rockets

Sponsors:• Florida Space Grant Consortium • Florida Space Institute• North East Florida Association of

Rocketry (NEFAR)

 Participating Teams:1. Embry-riddle Aeronautical University2. Florida Institute of Technology3. University of Central Florida

Florida Space Grant ConsortiumHybrid 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

Florida Space Grant ConsortiumHybrid Rocket Competition

Altitude DeterminationAltimetersA recording barometric altimeter must be used to record data for competition.   Determining Actual AltitudeThe 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 altimetersAltimeters 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 DeploymentMotor delay recovery system deployment is allowed.Motor Class Total ImpulseG or less: 160 Newton-seconds or less

1. Asteroid Assay Satellite for Path Identification, Research and Investigation of the Near Earth Object Apophis (AASPRIN) (Embry-Riddle Aeronautical University)

2. Experimental Investigation of Slosh Dynamics in Low Gravity (Florida Institute of Technology)

3. Space System Design (University of Florida)

ESMD Senior Design ClassAASPRIN

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 launches.

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 hardware Engineering drawings, materials list of fabrication plan.

Space Systems Design

• 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.
