|Active Control Stabilization of High Power Rocket |
High power rockets could become dynamically unstable due to outside disturbances after take
off. The instability is augmented when the rocket is "slow" off the launch rail, which happens when the thrust-to-weight ratio is less than 5:1. Due to these reasons, the objective of this
project was to design and build an active control system that will make sure the rocket follows a
straight path all the way to apogee. This will be done through a model-based design approach in which a 6DOF mathematical model of the ?ight dynamics will be created.
|Adventures in Rocket Science|
This guide was prepared by NASA as a tool useful for informal education venues (4-H, Boys and Girls Clubs, Boy Scouts, Girl Scouts, etc.), science clubs and related programs, and can be adopted for formal education settings. An exciting and productive study in rocket science can be implemented using the selected activities for the above-mentioned settings. The guide’s activities can be correlated to meet formal education’s core curriculum objectives or used for ancillary enrichment and extension activities.
|An Actively Stabilised Model Rocket
The goal of this project is the design and construction of a small (hobby-scale) actively-stabilised rocket that uses non-aerodynamic means to effect stabilisation about the pitch and yaw axes; control of the roll axis of the rocket was not required as that axis does not affect its stability in flight. Commercially-available components and materials were used wherever possible, both for reasons of cost and to allow this project's achievements to be replicated elsewhere. Maximising apogee height was not be considered; instead, the aim is to maintain a long stable flight at a low altitude.
|Building a Model Rocket Parachute Recovery System|
Discusses the math used to determine the correct size and type of parachute to use for a given model rocket. You will need a copy of Adobe Reader to view and print the document.
|Building a Model Rocket Parachute Recovery System|
This letter was written to a student interested in recovering his rocket with a parachute after the rocket's powered flight. The question was: "How large should the parachute be?"
We based our answer on the following design philosophy: Since rocket payload needs to be kept small, the parachute should be designed as small as possible. Also, using a small chute implies a more vertical and faster descent. In other words, using a large parachute usually leads to more horizontal drift due to winds aloft... i.e. more chances to lose the rocket in neighbor McNasty's backyard.

|Electrical Current Requirements of Model Rocket Igniters |
Every model or high power rocket flight begins with a single event. An igniter or electric match is electrically initiated which in turn ignites the blackpowder or composite propellant. For such a critical role, little technical information is available regarding the electrical characteristics of these devices. Some manufacturers of electric matches provide "no fire'" and "all fire" current. Ratings for their devices. While important from a safety perspective, this information conveys nothing as to the devices true electrical characteristics. This document sheds some much needed light on the electrical characteristics of electric matches

|Estimating the dynamic and aerodynamic paramters of passively controlled high power rockets for flight simulaton
High power rockets are essentially large unguided model rockets that can fly to altitudes as high as 13km and recover to earth by parachute. A rocket flight simulator can be used to predict the flight path of the rocket during the ascent. To do this the simulator requires certain input parameters. This paper summarizes some simple methods for estimating these parameters from very basic information such as the geometry of the rocket and the thrust curve. Methods for estimating the mass, centre of mass, moments of inertia, thrust damping, center of pressure, drag force and normal force are given in this paper. The methodology described in this paper has been used in conjunction with a rocket flight simulator to predict the flight path of a high power rocket. Some results are given in the summary of the paper.
|Exploring in aerospace rocketry: An introduction to the fundamentals of rocketry|
Developed at the NASA Lewis Research Center, Cleveland, Ohio, "Exploring in Aerospace Rocketry" is an educational publication based on the lectures and projects conducted during two years of the NASA-Lewis Aerospace Explorer program. This publication is intended not only to provide a basic explanation of some of the fundamentals of
rocketry but also to stimulate other government agencies, educational institutions, private industry, and business to establish career-motivation programs within their own
particular fields of activity.
|Forty Years of Model Rocketry: A Safety Report|
G. Harry Stine's 1997 report on safety for the National Association of Rocketry.
|High Power Rocket Design and Fabrication|
Cal Poly entered the scene in 1989 with its club, Cal Poly Space Systems. CPSS started out as a small group of aerospace engineering students aiming to apply some of their knowledge to space related experiments. They grew in number, and in the late 1990's, were asked by NASA to participate in their StarBooster project, whose goal it was to investigate if the Space Shuttle's solid rocket boosters could be remotely controlled and fly back for a soft landing, rather than falling into the ocean and having to be fished out. The project was successful and sparked the club's interest in high powered rocketry, an interest the club has pursued ever since. Through the years, several different projects have been completed, progressively improving the club's methods of fabricating rockets.
Until now, CPSS' fabrication methods haven't been documented, and have instead been passed down from experienced members to younger members throughout the years. This senior project documents those methods, providing the basis for a solid understanding of the elements of high powered rocket design and fabrication. It is also the intended that this documentation can provide the foundation for a class to offer practical application of the principles leamed during a student's aerospace career. Leaming the variety of skills required to build a rocket has helped me immeasurably, providing me with a wealth of knowledge that I've applied in the classroom, the workplace, and in real life, and it is my hope that this knowledge can be passed on and can benefit future generations of college students like it has benefitted me.
|How to Fold an Octagonal Parachute|
There are many ways to pack a parachute to fit into a rocket airframe. Some people have success with the scrunch-roll-and-stuff approach. Other people just cram the parachute into the airframe any old way they feel like at the time. Here is a step-by-step approach to turn your bulky parachute into a compact bundle and still give you reliable deployment.

|Modeling Model Rockets: A Study in Optimizing Model Rocketry|
Although rocket science involves advanced mathematics and meticulous calculations, model rocketry is a useful segue into the world of rockets. For this project, the team built eleven unique rockets from different model kits. After measuring the rockets's dimensions, they recreated their rockets in OpenRocket, a program used to simulate model rocket flight. After launching the rockets, experimental apogee was compared to a simulated apogee from OpenRocket and to a calculated theoretical apogee.
|Modeling Rocket Flight in the Low-Friction Approximation |
In a realistic model for rocket dynamics, in the presence of atmospheric drag and altitude-dependent gravity, the exact kinematic equation cannot be integrated in closed form; even when neglecting friction, the exact solution is a combination of elliptic functions of Jacobi type, which are not easy to use in a computational sense. This project provides a precise analysis of the various terms in the full equation (such as gravity, drag, and exhaust momentum), and the numerical ranges for which various approximations are accurate to within 1%. The analysis leads to optimal approximations expressed through elementary functions, which can be implemented for efficient flight prediction on simple computational devices, such as smartphone applications.
