What is PAYWARE

How PAYWARE works for you

Thrust

Weight

Drag

Payware sales info


Weight

Heavy rockets need more engine power or thrust to propel them. If two rockets have the same engine power  and the same drag, the lighter one will fly highest.


Thrust

Is the amount of power a rocket engine has. The thrust pushes the rocket along.

If you were given two rockets, both with the same weight and drag factors but each having a different thrust, the one with the most thrust would fly highest.


Drag

When a rocket flies through the air it needs to push that air out of its path. A thin, sharp rocket can cut through the air easily but a fat rocket with a round nose will not.

The force that the air places on a rocket is called drag. If you have two rockets, both with identical weight and thrust, the one with the least drag will fly best.


How rockets work
How rockets work.

Rockets come in two sorts, solid fuel rockets and liquid fuel rockets. Solid fuel rockets have one fuel container which holds a powdered or solid chemical mixture. This mixture will burn on its own and does not need to use air or oxygen in its combustion.  Well known solid fuel rockets include fireworks, most modern toy or model rockets and the boosters on the Space Shuttle. Liquid fuel rockets have two tanks, one for the fuel and one for an oxidising agent. This oxidising agent is needed so that the rocket can work in space where there is no atmosphere .

In both cases the rocket motor burns the fuel in a combustion chamber to produce large amounts of very hot gas. This gas escapes from a nozzle under pressure blowing the rocket along in much the same way as a balloon is blown along when you release it without sealing the neck.

Notes for Parents or Teachers

This program has been carefully designed to provide educational information while also providing a source of amusement. Your students learn while they think they are playing a computer game.

Extensive testing of this software has shown that children particularly enjoy the rocket race and are able to understand the basic physics involved. No attempt has been made to offer specific statistical information or to involve the student in complex mathematical calculations.

In a normal session start off by allowing the student to play with the rockets. Then after a few minutes point out that adjustments to the force factors make changes in the rocket flight characteristics. As the students understanding grows try and find out if you can make two or more rockets fly to the same height by balancing the forces differently. For example show that a rocket with medium thrust but a large drag factor will behave in a similar manner to a rocket with less thrust and a very small drag factor.

In all cases remember that experimentation is the key especially for very young students.

This software has actually been tested by users ranging from 4 to 14 years of age. In the case of the youngest it provides a usefull tool to promote computer literacy and mouse coordination skills. Children of 7 to 10 enjoy the races and experiment extensively with the forces involved. and for the older student it provides an amusing yet informative diversion from run of the mill studies.


How to register this program
Pricing information

This program is PAYWARE. This means that you can try it out, show your friends and even give them a copy if they like it. This software is not however free. We hope that we have provided you with a valuable program and, after you decide to keep it, you should register it.

1..if you are a private user you will require the printed documentation which comes as a teaching pack. The fee is 85 French Francs (around $15 U.S. ).

2..if you represent a school or college then you will require the full teachers pack. This contains a licence for 15 copies of the software (enough for most classes) You will also receive in the teachers pack, photocopy worksheet masters, marking information, a short historical guide to rockets and rocketry, AND a FREE version of the program which has not 3 but 5 rockets in the race, This option costs 150 French Francs. (around $25 U.S. )

The menu bar

The menu bar holds three selections Rocket, View and Help. To find out more select one of these.

Rocket

Help


The rocket menu
Rocket

This menu holds three options

Design, will allow you to choose a rocket and then change the way that rocket flies.

First choose one of the rockets. You can use all of them if you are on your own or if you have company let a friend choose one.

After you choose one you can alter the way that the rocket works with this control panel. Move the slider controls to change the weight, drag and thrust of your rocket.

Fly gives you a countdown and then begins the rocket race.

Speed Allows you to change the rate at which the rockets move. Younger users may wish to slow the rockets down so that the telemetry data is easier to read.

Exit lets you leave the program

Some of the functions in the Rocket menu are also duplicated in the tool bar.

The Individual controls perform these tasks

Change the rocket flight parameters

Race the rockets

Change the rocket speed

View the version number of the software


View menu

Has two options.

Toolbar lets you turn the toolbar on or off. The toolbar has push buttons which perform the same functions as Design and Fly in the Rocket menu

Status bar lets you turn the status bar at the bottom of the screen on or off.

Sales information
Rockets. Sales information.

Rockets is a simple educational program to demonstrate the principles of forces acting upon a rocket. Without resorting to complex calculation the program conveys the basic information that a student requires to understand how a rocket works.

This software is intended to supplement the educational resources of parents or schools who instruct students, particularly children, in basic physics.

If you have registered this software for your children you should introduce it to their school. The school may be able to integrate the package with the Physics, computer literacy or games library.

If you have registered this software for a school or college distribute your serial numbered copy to other schools or to parents interested in assisting in their children's education at home.
