Husker Rocketry


Husker Rocketry is a student-led design team that takes high-powered rockets from design to launch. Every year we compete at a new and exciting competition. The team works together in order build rockets that improve on a yearly basis. Husker Rocketry launches from the fields and aims for the stars.

2018-19 Husker Rocketry Team Progress Report

—————————2018-19 Competition: Midwest High-Power at North Branch, MN]———————

Objective: Design an “Efficient Supersonic” rocket.

First Flight: Fly as close to supersonic as possible on a Cesaroni 491-I-218-14A, 1-grain 54 mm diameter motor.

Second Flight: Fly supersonic with an I or J motor of choice.

Design/Manufacturing

The team has been researching new and more efficient methods to create their own carbon fiber tubes. Last year, the team tried making their own rocket carbon fiber tubes. However, they were not able to perfect the process. Now, the carbon fiber sub-team is experimenting by using the process outlined here.

The team has now finalized their OpenRocket design of the rocket and currently modeling the rocket using SolidWorks.

 
 

Above is one of the carbon fiber tube tests. The inside was rich with resin whereas the outside did not have enough.

Epoxy fillets with shredded carbon fiber strands allow for maximum strength while using minimum diameter.

2017-18 Husker rocketry team Competition Summary

About

This year's competition took place at Midwest High Power and the competition challenge was active roll control. The rocket needed to be able to control the rate at which it spins. The team incorporated a gyroscopic roll-control mechanism (a flywheel) inside of the rocket to control and manipulate rocket roll.

During the competition, each team launched their rocket twice. During the first launch, the objective was to control or minimize roll. The next launch was about manipulating roll; before the competition began, all teams were given specific roll orientation instructions for the second flight.

Midwest High Power Rules


Competition

On May 20th, 2018, the Husker Rocketry team competed at Midwest High Power in North Branch, MN. The rocket, ACROBAT (Angular Conservation Roll Oriented Body with Active Transmission) traveled 4124 ft on during the first flight and 4333 ft on the second flight. Launch and recovery for both attempts were successful.

The rocket was unstable right after takeoff during the first launch and there was no recorded video of the flight. The second flight proved to be more successful; the rocket came off the pad rather stable and video of the flight was received.

Overall, the team placed 3rd at the Midwest High Power competition. 


At the beginning the the year, the team experimentally made their own carbon fiber tubes. However, the carbon fiber tubes were not as aerodynamic as the team desired due to imperfections on the outside of the finished tubes. Therefore, the main carbon fiber body tubes of the rocket were purchased. Nevertheless, experience was gained from the work done with the carbon fiber building process.

The video above is this year's test launch of the rocket "ACROBAT." Launch and retrieval was successful despite complications with the internal roll-stability mechanism. The expected apogee was 4,500 feet and the rocket actually traveled 4,509 feet. A Cesaroni J760 motor was also used.


On May 20, 2018, the University of Nebraska-Lincoln's Husker Rocketry team competed at the annual Midwest High Power competition located in North Branch, MN.

Members


Members


The team has a place for anyone interested in building their knowledge about rocketry and aerospace engineering. Members who like crunching numbers and predicting the future find their niche in the design of our rockets’ brains: the payload. Members who prefer a more tactile focus can put their skills to the test through the precision construction of rockets that must withstand extreme flight conditions. And, a love for making things that go fast and high is the common bond that all team members share. However, Husker Rocketry is much more than a club for enthusiasts. We are proud of the considerable number of our members who can say they have interned for NASA, in part due to their hands-on experience gained from the team.
