About the Project
A few friends and myself who are Aerospace Engineering students at Embry Riddle Aeronautical University wanted to take on a new challenge. We came up with the idea of researching and designing a thrust vectoring system that will stabilize and help land a model rocket. With this at mind we met up for a few meetings to come up with what we would have to do to accomplish this. After research and planning we have come up with the designs for the Hermes Landing TVC Model Rocket.
What is Thrust Vectoring?
Thrust vector control (TVC) is a way that we can simply control a solid propellant motor in a rocket for stability. Solid propellant motors when ignited create an impulse in acceleration to begin the lift of a rocket then continue to burn at the motors rated thrust. This does not allow us to do much but to watch the rocket fly. When we take the fins off of a given rocket that rocket now has no control surfaces to fly straight. What TVC allows us to do is to put that propellant motor in a designed housing that we can control the angles of to push the rocket how we want. This ultimately lets the rocket fly without fins as you see on most commercial rockets nowadays and correct the flight path with stabilization since the motor angles can be controlled.
How we plan to do this
Our research has led us to find ways to build a TVC mount and how to use a flight computer with electronics to control that TVC. Once flight with a TVC has been successful more code can be added to the flight computer to create a motor burn for landing the rocket back on the ground without a parachute using landing legs like that of the SpaceX Falcon Heavy boosters. For more information on our design, parts, research, and experiences you can look at our project conceptual design review (CDR) in this powerpoint.
Where your money goes
Once your funds are received the money will go to help with the project. This includes the cost of parts and materials we need to build the rocket, costs of the solid fuel propellant motors that are $30 a motor, the testing setup for the rocket, and anything else that comes along in the process.
Thank you for checking out the Hermes Landing Model Rocket and we appreciate any funds you donate.
Risks and challenges
Like anything there are risks. In the model rocket world the most common risk is where the rocket will go. For this we plan to have plenty of rocket ground tests to include motor burns while the rocket is secured and going to an open and clear field for firing.Learn about accountability on Kickstarter
