Welcome to UE's USLI Team Home Page

Welcome to the 2011-2012 University of Evansville USLI Rocket Team’s website! The UE Rocket Launchers, which is their unofficial team name, are looking forward to competing in the USLI competition in Huntsville, Alabama this coming spring. A few years ago, a group of senior mechanical engineering majors decided to compete in the 2009-2010 USLI competition. They were accepted into the competition and placed seventh their rookie year. This year, the team is composed of new members that are optimistic about reaching their goals. In order to accomplish their goals, the team needs to focus on teamwork, communication, and dedication. Designing, testing, and fabricating a fully functional rocket that will be capable of achieving an altitude of one mile is one of the team’s goals for this year. Each member of the team is thankful for the opportunity to compete in this competition. It will be a fun and exciting year!  


Team Log:

March 27– April 5

The team had to wait nearly a month and a half to launch the full scale rocket. They finally launched the full scale rocket on March 31 in Lafayette, IN at Thunderstruck. The rocket recovery was a success only with a few minor scratches. The team was very pleased with the results from the rocket. The only problem was that the payload did not work as planned because the microcontroller did not record the voltage from the fan. The team plans on launching the rocket one more time before they go to Huntsville.


March 11– March 26

For the past four weeks the team has been doing a lot of prep work for the launch in Huntsville. The team worked on and completed the FRR report and presentation. The team only made a few changes since the CDR report. These changes included the parachute size, a remote control for the payload circuitry, and the overall height of the rocket. The team is still waiting to launch their full scale rocket due to inclement weather, motor, the FAA waiver, and the launch site. The team plans on launching the rocket for sure on March 31 in Lafayette, IN at Thunderstruck. The team also performed one of their four educational engagement requirements. The team went to the Boys and Girls club to talk about rocketry and to perform an activity for them.


March 3 – March 10

This week the team worked on finishing the launch pad. The team finished bolting, welding, and assembling all of the components of the launch pad  during their spring break. The team plans on launching their rocket on March 17 at Launch Crue in Holland, IN. The team also performed another test on the payload. The team was able to determine the rotational velocity of the fan using an air compressor, a stroboscope, and a pressure gauge.  


February 21 – March 2

As mentioned below, the team is now working on testing the payload. The testing includes: maximum voltage output from the fan when the rocket is at maximum velocity, translating the pressure from an air compressor to a velocity, fan rotational velocity, and remote testing for turning the microcontroller on/off. The team needed to convert pressure to velocity in order to set the air compressor at the velocity of the rocket. For the rotational velocity of the fan, the team used a stroboscope and the team used a voltmeter to determine the maximum voltage the fan will produce.


February 8 – February 20

For the past few weeks the team has been working on the full-scale rocket. Once the team received all of the materials, they began constructing the rocket. Since the team already tested the full-scale rocket in January and everything worked properly, the internal components for the payload and recovery system will remain the same. The team still needed to put the bulkheads, bolts, and the Dyna-Wind tubing on each section. The team is now finished with the fabrication of the rocket. The team has also painted the rocket with its base colors: purple and orange. Since the rocket is completed, the team is now focusing on testing the payload section.


January 10 – January 24

This week the team worked on the writing the Payload and Vehicle sections of the CDR report. They also prepared and practiced for the CDR presentation. Along with working on the CDR report, the team was also preparing for the Feb. 18 full-scale launch. The team ordered the Dyna-Wind tubing for the rocket body and had them cut and slotted for the fins. The team also ordered the custom primary and secondary fins.


January 3 – January 8

This week, the payload and motor sections were completed. The test rocket was launched on January 7, and it was a successful flight. All sections of the rocket were recovered, and the payload worked. A curve was plotted, and the voltage produced by the payload fan increased as the velocity of the rocket increased.


December 19 – December 23

Construction began on the payload, recovery system, and motor section. One important modification was made to the payload: replacing the duct fan with a computer fan. The duct fan was replaced because it failed to turn when tested with the air compressor. For the test flight, a Cesaroni Technology motor L990 blue stream motor will be used, because the motor intended for launch day (L1030) was not in stock. The L990 and L1030 motors have similar impulses, burn times, and dimensions.


November 28 – December 4

The team began ordering parts for full-scale test rocket. Center rings, bulkheads, airframe, a Close Proximity Recovery system (CPR), and altimeters were among the parts ordered. On December 11, Britain plans to receive his Level 1 certification, and the team plans to launch Dr. Ungerís repaired rocket.


November 7 – November 13

The team completed the construction of both rockets this week. Cord and Taylor finished repairing Dr. Unger’s rocket and Britain completed his rocket for Level 1 certification. The team planned on launching the rockets this past weekend, but due to inclement weather conditions, the team decided not to launch. This past week the team has also been working on the construction of the payload and different ways to test the nosecone/payload. The team is going to test the nosecone physically and analytically in this coming week. ANSYS and NX-7.5 are the two modeling programs that are used to analyze the nosecone. A flow analysis is going to be performed on the nosecone with and without the payload.  


October 24 – October 30

This week the team is still focusing on the payload design and different ways to test it. Additional work still needs to be done in order to confirm that their payload design will work. The team also purchased a rocket kit for Britain to receive his Level 1 certification. He plans on launching the rocket on November 13. Some of the other members of the team are repairing Dr.Unger’s old rocket. They also plan to launch this rocket on the same date. 


October 17 – October 23

Today, the team was notified that they were selected to compete in the 2011-2012 USLI competition. Later that week, the team participated in a teleconference with the NASA officials. They got an opportunity to meet the NASA officials and receive valuable information about the competition. After the team, submitted their proposal to NASA, they decided to change their payload design. The team has been focusing all their attention on the design of the payload. Since many of the team members do not have experience with rockets, they decided to purchase a model rocket to gain knowledge and hands on experience with rocketry.
