A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:
Proof of Concept
Explorations that test ideas and functionality.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.
We are a team of Virginia Tech students whose goal is simple: to put a rocket in space. Specifically, we want to be able to place 5U of CubeSat (7 kg) into Low Earth Orbit with our orbital launch vehicle called Hokie 1. Something like this has never been done before by an amateur organization and it will have huge implications for low-cost access to space. Colleges across the country could follow our lead and develop a method to put satellites and small experiments into space themselves.
This will give a serious boost to the space industry and give students who are, like us, extremely passionate about space an opportunity to gain hands-on experience on a project that is directly relevant to their future careers. Initially, our plan of action was not to reach space with our next rocket; however, we are confident in our propulsion system and are going for the space shot with Hokie 0.6.

The funding we receive here will go specifically to the design and building of our current two-stage rocket, Hokie 0.6, capable of reaching space. If successfully launched in September at BALLS 27 in Nevada, OLVT will become the first undergraduate body to reach space. Hokie 0.6 is a two staged Q to P rocket intended to test avionics, parachute deployment, and structures up to the Karman line.
We are using a conical nose cone due to its ease of manufacturing. Avionics and telemetry will not be stored inside the nosecone, so it is optimized for speed and drag reduction.
Avionics and Telemetry
The brains of Hokie 0.6 consist of two Arduino Megas and two Raspberry Pis for a double redundant avionics system. 9 DOF inertial measurement units, accelerators, barometers, thermometers, and GPS units will collect accurate flight information describing the rocket's trajectory. Hokie 0.6 will use a telemetry system located below the nosecone to send this data back to a ground station during flight.
With a two stage rocket we want as straight of flight path as possible to decrease wind tilt during interstage coasting. We are using trapezoidal wings to decrease overall drag contribution. A 1/3 degree fin will generate a 3-4 Hz spin rate for added stability.
We are developing an ammonium perchlorate based propellant following proper safety regulations and precautions. This includes: safety equipment, handling of chemicals, disposing of chemicals, and safely testing any final product. All propellants, formulas, and processes are critiqued by professionals in the field of solid rocket motor propulsion. Furthermore, OLVT strictly adheres to ITAR 120.15.
Funding Needed: $5,838
The purpose of this Kickstarter is to fund the parts listed. The rest of our budget has already been funded through Virginia Tech and other companies such as Orbital ATK, SolidWorks, AMW Pro-X, and BurnSim.
We have been accomplishing our goals through a stepping stone approach to build up our credibility. The rocket we plan to design and build that will be placed into low earth orbit will be called Hokie 1. Before we can make Hokie 1, we have to prove that our team is capable of launching a rocket into low earth orbit. To prove this, we have started small with Hokie 0.25, 0.5, and now we are making Hokie 0.6.
A small single stage rocket that was launched multiple times in Blacksburg, Virginia and Maryland with J and K motors. The purpose of these launches were to get members on the team Tripoli high power rocketry certified. This single-stage rocket reached a maximum altitude of 5000 ft and had an installed impulse of 676 Ns.
A two stage rocket that is similar to our design for Hokie 0.6. The sustainer was launched in Nevada in September of 2017 at BALLS 26 and then both stages were launched in November of 2017 at Kloudbusters. This double-stage rocket reached a maximum altitude of 17,000 ft with an installed impulse of 15,000 N-s.
Risks and challenges
The risks are those related to the rocket launch: it is a very complex procedure whereby every single detail is critical to a successful launch.
However, we have many mentors that are guiding us through the process, teaching us, and checking our work along the way. These mentors consist of Virginia Tech faculty member advisers, high-power rocketry vendors, and professional engineers from Orbital ATK and Ulyssix Technologies, Inc.
