Are you new to model rocketry? Do you know what to expect when you build and fly a rocket kit? This article will try to help you by explaining what happens when you launch a model rocket. It will also point you in the right direction where you can find even more information to help make you into a rocketry expert.
Begin by looking at the picture to the right. If you are teaching others about rocketry, and you want to have a printable copy of the image, you can print out the one that appears in the Peak-of-Flight Newsletter You will find that having a poster to hand out will be helpful. Please feel free to share it with your friends. Phase 1 - Ignition and Liftoff A model rocket is always ignited by "electrical ignition. This device is called a "launch controller. You can make your own if you have some basic electrical skills.
There are plans for several different launch controllers in the booklet: Electronic Model Rocket Launcher Construction Plans. If you want to save time, you can buy a launch controller. They are usually sold as a set along with the launch pad. You can find a good one at called the Sky Launch System. Why electrical ignition? This is a common question. The answer has to do with "safety. But that would sacrifice safety. Once a fuse is lit, there is no stopping it. If the rocket should tip over, or an airplane suddenly appear in the sky, you couldn't halt the launch.
The other item shown in the picture is a launch pad. Again, many new modelers don't understand the need for a launch pad that includes a launch rod. After all, the Space Shuttle doesn't have a big launch rod The purpose of the launch rod is to guide the rocket until it reaches sufficient speed where the fins take over and keep the rocket moving in a straight path.
This is approximately 30 miles per hour. By the way, the reason the Space Shuttle, and other large rockets don't have launch rods is because they have rocket engines that are steerable. In other words, the direction the rocket engine pushes controls the path of the rocket. Our model rockets have a fixed nozzle. They will only move in one direction. So we need a rod to keep the rocket moving in the "upward" direction. Without a rod, the model can easily tip over at lift-off, and come screaming right at you.
So for safety, we have a launch rod that keeps the rocket pointed up. Starters The actual device that starts the motor burning is the "starter. These wires are hooked up to the launch controller that we discussed earlier.
When the electrical current passes through the starter, it heats it up and causes it to burst into flame. This flame is what actually starts the propellant burning in the rocket motor.
How do you hook them up? It's pretty simple. Check them out! The Rocket Lifts Off Once the motor ignites, it begins to generate thrust. It is this thrust force that pushes the rocket into the air.
While the motor is making thrust, you'll normally see a flame coming out the back of the motor. Sometime it is hard to see because the rocket moves so fast. At the same time, the rocket motor is making a loud roar and a lot of thick dark smoke. Articles Phase 1 - Ignition and Lift-off. Phase 2 - Engine Burnout The propellant inside the motor burns quickly. In most motors, the propellant is consumed in less than three seconds, at which point "burnout" occurs. This means the motor is no longer producing a thrust force.
By the time the motor burns out, the rocket has already reached its top speed. It cannot go any faster from this point on. Most people are surprised that burnout occurs at a very low altitude. While the rocket may reach hundreds or thousands of feet in the air, the burnout location on most rockets is about feet in the air. If you want to predict when the burnout occurs during the flight, you can do this with the RockSim software. Articles Phase 2 - Engine Burnout.
Phase 3 - Coasting When the motor burns out, the rocket may be traveling hundreds of miles per hour. We don't want the parachute to come out of the model while it is going this fast. Otherwise, it will be ripped to shreds. We want the model to coast upward and bleed off some speed. The period of time that starts at engine burnout, and ends when the parachute is ejected out of the rocket is called the "Coast Phase. Even though the rocket motor isn't making thrust, there is something happening inside of it.
The special composition called the delay element or delay grain is burning at a slow rate. See how model rockets work! It is obvious that something is going on, because there is still smoke coming out of the rocket motor. Maybe this is what causes confusion among new modelers that they think the motor keeps burning all the way until it reaches apogee the highest point in the flight.
The smoke serves a purpose though. It allows us to track the rocket -- in other words, to follow its progress into the air. Sometimes the rocket moves so fast, that it is hard to follow with our eyes. So the smoke gives us a visual indication where the model is. There is something worth mentioning. The smoke produced by the delay grain is not as dark or as thick as the smoke produced by the motor while it is producing thrust.
The delay smoke is whiter, and wispy. Articles Phase 3 - Coasting Phase. Phase 4 - Apogee and Ejection When the delay composition is done burning, it starts the "ejection charge" that is also built into the motor.
This ejection charge burns quickly, and is directed inside the rocket. It's goal is to push off the nose cone, and eject the parachute out of the rocket. Typically, we desire the ejection to occur right at apogee the highest point in the trajectory of the rocket.
It is at this point the rocket has slowed down to its minimum velocity. So when the chute comes out, it isn't hit by a huge gust of air.
The modeler controls when the ejection charge pushes out the parachute by proper motor selection. If you use a motor that has too long of a coast phase delay, the rocket will arc over, and will eject the chute while the rocket has built up some speed when it is coming back down to the ground. Likewise, too short of a delay will mean the rocket hasn't coasted to its highest point. Articles Phase 4 - Apogee and Ejection.
Phase 5 - Recovery After the parachute has ejected, it fully inflates, and the rocket has begun its recovery phase. Nothing much happens during the recovery phase. The model just drifts slowly to the ground under the canopy of the parachute. But it is at the mercy of any wind that is blowing.
The stronger the wind, the further the model will drift away from the launch pad. Because of this, modelers have searched for ways to keep the model from drifting out of sight. The most common thing they do is to switch from a parachute to a streamer. A streamer does the same thing as a parachute, but it falls faster, so it doesn't drift as far. There are other things a modeler can also do to prevent the rocket from drifting too far. You could cut a hole in the canopy of the chute, to make it fall faster.
Similarly, you can tie the suspension lines together to reef the chute to prevent it from opening fully. Again, this makes the rocket fall faster, so it doesn't drift as far during the recovery phase.
Articles Phase 5 - Recovery. Summary With the exception of the recovery phase, the flight of the rocket is controlled by the rocket motor.
Anti-alias of the 2D image. This package was written by Steve Roberson, who passed away in From your kids, to yourself -- each of you will gain something new and unique from using RockSim. I'm looking to get High Power Certified. With RockSim, it is even possible to simulate an unstable model, and watch it do loopy loops on the computer screen!
Model rocket flight profile. Static Fire
It adds a level of safety, because the students can check to make sure their rockets are stable before they build them. The new enhanced "flight profile" movie is an excellent teaching aid for showing new modelers what to expect when they launch their rocket. Even advanced modelers will gain more flight experience in one evening of "play" with RockSim than they'll get over an entire year of trial-and-error out at the rocket range.
More importantly, with RockSim they can determine if the rocket will land within the field with the motor they have chosen.
How many times do kids want to put the "biggest" motor into their rocket, only to find out that it is lost as it drifts away into the next county? Quickly learn the basics of RockSim by watching video instruction clips.
By running simulations prior to launch, they'll be able to see clearly what to expect when the rocket takes off, and where it could land if they choose a rocket motor that is too big. RockSim also generates a lot of data that your students can explore. It can graph out 68 different flight parameters, which includes things like: altitude, velocity, acceleration, and Mach number.
There is so much information that your students will learn a lot about rocketry and how to interpret graph data. Besides displaying the information on a graph, the data can be exported out and read into a spread sheet program. Then your students can get some practice manipulating data in spread sheet software too. You can read about all the different uses of RockSim in your classroom! Here is another link for you too; it shows how to use RockSim to specifically teach science with a sample lesson.
Do you notice that they all choose RockSim to design their rockets? Then take a look at independent web sites like www. Do you see that there are thousands of rocket designs that you can download that are only in the RockSim format? With RockSim, you have compatibility with most of the rocket flying world.
You'll be able to email files to your friends, and offer them advice on their own rocket designs. RockSim is made in the USA , and was developed by a real aerospace engineer that actually worked at Cape Canaveral in Florida launching the big rockets into space. That experience has lead to a program that can do the things that other manufacturers have come to trust. That is why you should consider it for your projects too. But I'm going to tell you another secret. As much as it can do, RockSim can't do "everything.
That is what has made RockSim what it is today -- great ideas from people just like you. Instead of letting those users feel frustrated, we've made it possible for other computer programmers to write software that interacts with RockSim. We started this process in version 6, when we switched to a XML file format I'm sorry for the techie-talk, but if you know what XML is, you'll appreciate the advantages.
Allowing other programs to interact with RockSim has a lot of benefits. You get new and sophisticated features faster, and the independent computer programmers are not trying to re-invent all the features that RockSim already has.
If you are a programmer yourself, you may want to tie into RockSim's advanced features to save programming time. Here is a listing of programs that interact with RockSim. I'm sure that there are more to come, but take a look at this list:.
Well over 4, people have invested their own money in RockSim. That includes nearly all of the Level 3 certified fliers, hundreds of aerospace engineers, all the champions in the Team America Rocketry Challenge, hundreds of teachers, and also the innovative modelers that know a great value when they see it. Plus, nearly every major model rocketry company uses RockSim to design their own kits and they've paid to use it!
When you invest in RockSim today, you'll be joining a select group of people, educators, engineers, and companies that are concerned about the future of rocketry. They know the value of rocketry as an educational tool, and they want to pass it down to future generations of modelers.
So they are investing in RockSim because it allows them to teach others about rocketry, and it keeps their own rocketry projects safe and legal. Based on this information, take a brief moment and answer this question: "What would you do if a fellow rocketeer or teacher told you that RockSim is a bargain and you should invest in it? Compared to what? Think about what you get with RockSim that you can't get anywhere else.
Here is a very quick review of some of what you get when you invest in RockSim:. But I want all modelers to design, build and fly the safest and most spectacular rockets. So I am allowing people to invest in RockSim at a tiny fraction of what it is actually worth. I want you to imagine something for me. Pause for a moment, and please describe how much fun it would be for you to be sitting in front of your computer running RockSim. Then ask yourself out loud, "What would happen if I did invest in RockSim to help with my next project?
You have no obligation to buy; just try it out for 30 days and see if it fits your needs. If you are ready to invest in RockSim, you can place your order by choosing your version and clicking on the "Add to Cart" button below. But before you do, here are some special items you'll also receive if you invest in the CD-ROM edition:.

How does RockSim differ from other programs? How easy is it to learn RockSim? What are the educational benefits to using RockSim? How is RockSim compatible with maunfacturers and other software? Who else uses RockSim? Is RockSim Expensive?
So, you're designing a rocket. You have several options for judging stability of a design. RockSim Design Software See below! Here is what our customer's say about RockSim: "I am really impressed with your software program, not only for the ability to design a rocket, but also the information that can be obtained with launching the rocket under various conditions, etc.
RockSim allows you to take your cool rocketry ideas, and flush out the concept to see if they'll be stable when you launch them. This is important, because you want to make sure all your homebrew creations are safe. This process of selecting parts, and arranging them into a rocket to see if it will work is called "designing" a rocket. I'm sure you'll be interested in a multitude of statistics: How fast it will zoom?
How high it will soar? How long it will hang in the air after the recovery device is deployed? This is accomplished with a rocket "simulation" program. I changed the shape or the number of fins on my rocket? What if I changed the length of the rocket? I added pods to the rocket? I use a 38mm motor instead of an 29mm?
I use a streamer instead of a parachute? The coefficient-of-drag is broken down into various contributors: nose cone and body profile drag, base drag, launch lug drag, and fin drag.
You can use this feature to tweak your rocket for optimum altitude performance. Again, RockSim was the first, and is still the only, design program that has this feature. Without it, you can't really tell with any certainty how high or how fast the rocket will travel, let alone what the trajectory will look like. That is a very simple question to answer once you have RockSim. Just imagine people coming to you for that answer.
With it, you can: Print out fin templates. RockSim's fin templates can be highly complex and include the through-the-wall fin tab and curvature matching of the boat tail. If the fin is huge, RockSim tiles the template onto several sheets of paper with corner marks so you can assemble them like a puzzle. These templates can be transferred to wood or fiberglass, and cut out to make actual rocket components.
Print out transition-section pattern sheets which you can assemble into an actual part in your real rocket. To use this feature, you simply need to print out the transition template from the print menu. However, there are a few conditions you have to set up prior to printing it out: 1. The transition cannot have shoulder inserts specified. The transition must be set to "hollow. The transition shape must be set to "Conical. Note: That if any of these conditions are not as specified above, you will get the default "side view" of the transition when you print out the template.
Rocket Tip: Do you need help in assembling your transition? Click here to watch a movie on how to make the perfect transition. Print out nose cone templates that you can use as an aid in turning or carving your own component. Print out 2D blueprint-like drawings of your rocket.
These serve as a guide, so that you position the components properly when assembling the rocket. Print out a 3D picture of your rocket, including the paint scheme and your own custom decals.
From this, you'll have a guide for painting and decorating your rocket design. And it is something you can share with your friends to prove you designed the rocket yourself, and it really isn't a kit you've built.
Print out a parts list, so you can check them off as you order them from your favorite vendors. Print out exact centering ring templates, that can be transferred to wood sheets, from which you can cut actual rings. You can email your completed RockSim design to vendors like Balsa Machining Service, who can custom make nose cones, centering rings, and fins directly from your design file.
So you can buy many of the custom parts you've made in your design. Also, with the RockSim9 update, the following features were added: External Pods can be added to the outside of the main body Strap-on Booster Pods are ejectable during flight Fins can be attached to other fins Ability to scale your design up or down Scale custom fin shapes up or down New plot graph screen.
You can zoom in on any area of the graph for a closer look at the data. Anti-alias of the 2D image. New 2D top-view to go with the existing side and base view. New stability overlay to see if your asymmetrical designs are stable in all axis.
Incorporated engine search feature to find new motor data files on the web site www. Tell Me More About This Thing Called "Dynamic Stability" For nearly 40 years, modelers have used "static" stability methods to find out if their rockets will travel in safe manner. Is That True? You can view some of them here: Quickly learn the basics of RockSim by watching video instructions Requires QuickTime Player These step-by-step videos walk you through creating a designs, running simple simulations, modifying the user settings, creating asymmetrical fins, playing with the competition settings, and viewing the flight profiles.
Educational Aspects of RockSim RockSim is a "Certified Educational Product," which is a special recognition given by the Space Foundation to products used in educational environments that stimulate interest and knowledge about space. You have to ask yourself, "Why did these other companies choose RockSim?
I'm sure that there are more to come, but take a look at this list: FinsFun - Allows you to create fin alignment templates and positioning guides to aid you when it comes time to attach the fins on your rocket. RS-PRO - A 6-degree of freedom launch simulation program that is used to determine the landing zone for high altitude rockets. Laser Cut Fins - You can send a RockSim design file right now to Balsa Machining Service, and without any other instructions, they can cut all the flat parts for your rocket using their laser-cutter.
That means you can get fins, and centering rings, and even your body tube slotted to accept the fins tabs. As you can see, if you don't use RockSim, you will not be compatible with the rest of the rocketry world. So stop and ask yourself: "What would happen, and how would you feel if you didn't get RockSim today? Here is a very quick review of some of what you get when you invest in RockSim: Tried, Tested and True: People that spend thousands of dollars on big rocketry projects trust the results of RockSim.
For them, it is very cheap insurance on making sure their expensive rockets will work correctly. Compatibility: More people use RockSim than all other programs combined. Nearly all the major rocketry manufacturers use RockSim too. This allows you to swap and download RockSim designs to save you even more time and money.
