Rec.Models.Rockets FAQ (Frequently Asked Questions): PART 1 OF 14

GENERAL INFORMATION

This portion of the r.m.r FAQ is maintained by Buzz McDermott, at snipped-for-privacy@ix.netcom.com. Comments, criticisms, suggestions and corrections for this section should be sent to that email address.

1.1 What, exactly, is a 'model rocket' versus a 'high power' rocket? Where do liquid fueled and homemade rocket motors fit in? What about amateur rockets?

'Model', 'high power', 'advanced', and 'amateur' are all terms which have many definitions, depending to whom you are speaking. In r.m.r., and in the FAQ documents, the definitions (if any) accepted by the NFPA, National Association of Rocketry, and Tripoli High Power Rocketry Association are used. If these definitions conflict the NAR definition is used.

'Model rockets' are rockets that conform to the guidelines and restrictions defined in the NFPA 1122 document. These rockets weigh less than 1500 grams, contain less than 125 grams of total fuel, have no motor with more than 62.5 grams of fuel or more than 160 NS of total impulse, use only pre-manufactured, solid propellant motors, and do not use metal body tubes, nose cones or fins. One inconsistency with this is the CPSC definition of a model rocket motor, which by their definition must contain no more than 80NS total impulse. NFPA document 1127-94 contains the most complete definition of a model rocket and the model rocket safety code. This is the same safety code as adopted by the NAR.

'Large Model Rockets' is a term used in the FAA FAR 101 regulations. It refers to NAR/NFPA model rockets that are between 454 and 1500 grams (1 to 3.3 pounds) total liftoff weight or contains more than 113 grams but less than 125 grams of total fuel.

'High power rockets' are rockets that exceed the total weight, total propellant or single motor total impulse restrictions of model rockets, but otherwise conform to the same guidelines for construction materials and pre-manufactured, commericially made rocket motors. High power rockets also allow the use of metal structural components where such a material is necessary to insure structural integrity of the rocket. High power rockets have no total weight limits, but do have a single motor limit of no more than O power (40,960NS maximum total impulse) and have a total power limitation of 81,920NS total impulse. NFPA document 1127-1985 contains the most complete definition of a high power rocket and also the high power rocketry safety code. This safety code has been adopted by both the NAR and TRA. Metal bodied rockets are allowed by NFPA 1127 where metal is required to insure structural integrity of the rocket over all of its anticipated flight.

'Amateur' rockets covers all other non-professional rockets that do not meet the criteria for model or high power rockets. This includes metal bodied rockets, liquid or hybrid fueled rockets, and rockets with any type of homemade rocket motor.

'Experimental' rockets is an ambiguous term. In the early 1980's it was used (reportedly coined by the magazine 'California Rocketry') to describe rockets that exceeded the model rocket limit at that time (1 pound total liftoff weight and no motor above F power). More recently, it has been used by the Tripoli Rocketry Association to describe the class of rockets that use pre-manufactured solid or hybrid rocket motors but that do not qualify as high power rockets. This includes metal bodied rockets and those with more than 80,000NS of total power.

'HPR-lite' is not any type of 'official' rocket designation but has been used to refer to rockets that exceed the old NFPA model rocket limit of 1 pound but still qualify as NFPA model rocket under current guidelines. These rockets typically use E through G power and are built with much the same techniques as high power rockets. This term originated in the internet 'rec.models.rockets' newsgroup. It should be noted that this term refers to legal model rockets, not any type of high power rocket, and might therefore be misleading to many. The term 'Large Model Rocket' should be used instead.

Another term that has no formal definition but is more and more being used in the literature is 'hobby rocketry'. This term includes both model and high power rockets, but excludes amateur rockets. The term 'consumer rocketry' has also been used, and means the same thing.

The term 'non-professional rocketry' encompasses all forms of model, high power and amateur rocketry.

Finally, the editor of this document wishes to get on his soapbox for just one moment and add the term 'stupid rocketry' to cover all those who attempt to casually produce their own rocket fuel and/or motors without the benefit of very serious study, and implementation, of the processes involved and safety measures required. Especially note that this comment is NOT aimed at serious amateur rocketry organizations, college level research, etc. End of soapbox.

-------------------------------------------------

1.2 NFPA, FAA, DOT, ... Who are all these organizations and how do they affect the rocketry hobby?

DOT (Dept. of Transportation) regulates shipping of rocket motors and reloads. CPSC (Consumer Products Safety Commission) regulates what may and not be sold as a 'consumer' items at the retail level. FAA (Federal Aviation Administration) is responsible for airspace control and regulates flights of rockets that exceed 1 pound and enter FAA regulated airspace. NFPA (National Fire Protection Association) makes recommendations for use of non-professional rocket motors. Although the NFPA only makes recommendations, most state and local laws concerning the use of model rockets are based, at least in part, on NFPA recommendations; especially NFPA 1122. The NFPA also has a draft definition and safety code for High Power rockets, NFPA 1127. BATF (Bureau of Alcohol, Tobacco and Firearms) has responsibility for regulations concerning storage and use of explosives. This agency has taken a recent interest in looking into how high power rocket motors are stored and used. ATC (Air Traffic Control) You must notify the nearest FAA ATC center prior to flying Large Model Rockets or High Power Rockets.

-------------------------------------------------

1.3 What is the current legal status of model and high power rocketry in the U.S.?

A. FAA Regulations: * Rockets containing less than 113 grams of total fuel and weigh less and one (1) pound do not require any type of FAA notification and are not restricted by the FAA except where they pose a threat to aircraft. * FAA "large model rockets" (see the definition in #1, above) require that the nearest Air Traffic Control center (ATC) be notified of the launch between 24 and 48 hours prior to the launch. This is notification and not permission. In the U.S., try calling 1-800-WX-BRIEF to get the number of the ATC center nearest you. * FAA High power rockets (weighing more than 3.3 pounds, containing HPR motors, or containing a total of more than 125 grams of fuel) require a formal waiver be approved by the FAA and activated prior to the launch. Refer to the full r.m.r FAQ (dated 1 Oct 94 or later) for more complete details. * NOTE THAT THE FAA DOES NOT PLACE ANY RESTRICTIONS ON FUEL-PER- MOTOR OTHER THAN THE TOTAL LIMIT OF FUEL. HOWEVER, MOTORS WITH MORE THAN 62.5 GRAMS OF FUEL ARE HIGH POWER ROCKET MOTORS AND REQUIRE HIGH POWER CERTIFICATION TO FLY. This does allow HPR certified flyers to conduct low-end HPR launches (with up to about 240NS composite motors) without having to obtain a waiver. * Remember that HPR waivers, ATC notification and high power certification are all separate issues and must all be properly followed. B. CPSC Regulations/Restrictions: * G class model rocket motors (80.01-160.00NS total impulse) have been classified as high power by the CPSC. They are considered model rocket motors by the NFPA. These motors are now restricted for sale to buyers 18 years of age or older. This includes the sale of G reloadable motors. C. DOT Shipping Restrictions: * Most single use rockets motors with less than 62.5 grams of propellant are now classified as UN 1.4s and can be shipped via UPS (with a HAZMAT fee) or regular parcel post. * Most reloadable rocket motor fuel grains weighing less than 62.5 grams each are now classified as 'flammable solids' and may be shipped via UPS (with HAZMAT fee) or regular parcel post. * The UPS HAZMAT fee is now $10 * Any single use rocket motor containing more than 62.5 grams of fuel, and any reloadable motor fuel grain weighing more than 62.5 grams are classified as UN 1.3c, or Class B, explosives. These motors and reload grains may be shipped ONLY via Federal Express to certain designated shipping points. * Aerotech has announced it has received an exemption for single use motors up to K class and reload grains for at least L, and possibly M class motors, which allow these motors and reload grains to be shipped UPS ground in the same manner as motors containing less than 62.5 grams of propellant. Aerotech says these are now shippable as class 4.1 flammable solids. D. BATF Restrictions: * Any rocket motor or reloadable fuel grain containing more than 62.5 grams of propellant is now classified by the ATF as a Class B Low Explosive. This includes Aerotech reloads from J power and up. * You must have a federal Low Explosives Users Permit (LEUP) to legally purchase Class B rocket motors, reloads, and thermalite except under certain restricted circumstances. * You must have a federal LEUP to legally store rocket motors or reload grains which contain more than 62.5 grams of propellant. * You must comply with federal low explosives regulations when transporting and storing Class B rocket motors. * You must be 21 years of age to obtain an LEUP. E. Other High Power Restrictions: * You must be 'high power certified' to fly high power rockets. * The NAR and Tripoli both have programs for obtaining high power certification. You need to join one or both of these organizations if you want to fly high power rockets. * You must be at least 18 years of age to become high power certified.

-------------------------------------------------

1.4 I would like to get into Large Model Rockets. What are my options? Who has NAR certified E, F and G motors today?

The following manufacturers currently have NAR certified E, F and G motors, as indicated.

Motor Class Manufacturer Propellant Type

E Flight Systems, Inc. Black Powder E Aerotech/Apogee Composite (ammonium perchlorate) F Flight Systems, Inc. Black Powder F Aerotech/Apogee Composite (ammonium perchlorate) G Aerotech Composite (ammonium perchlorate)

There are 18, 21, 24, 27 and 29 mm diameter motors available. One manufacturer (Aerotech) has reloadable motor casings for 18, 24, and 29 mm motors.

Several manufacturers sell rockets designed for E through G powered flight. Refer to the previous list of addresses and get a few catalogs. R.m.r readers have recommended kits from NCR, THOY, LOC, Aerotech, Vaughn Brothers, and others. Look for the following minimum features in E through G powered kits: - plywood or fiber centering rings rather than paper or cardstock - plywood, thick plastic, or G10 fins rather than balsa - thicker motor tubes - cloth rather than plastic parachutes - thicker-walled body tubes

Remember to build these models stronger than smaller model rockets. Use CA and epoxy rather than white or yellow glue. These rockets will have to survive much higher stresses than smaller model rockets.

-------------------------------------------------

1.5 Is the proper term rocket 'engine' or rocket 'motor'?

I don't know. I don't really care. And neither should you! In this document 'motor' and 'engine' are taken to mean the same thing and both refer to "the thing in the rocket which makes it go 'whoosh!!' (or 'roar', if flying high power :-)". If you want a sure way to start a fight with a fellow rocketeer, just argue that whatever term he/she uses is the wrong one.

-------------------------------------------------

1.6 What do the letters and numbers on a model rocket motor mean?

The NAR has developed a motors classification scheme which has been mandated by NFPA 1122 and most state regulations. This system specifies the motors total impulse class, average thrust, and ejection charge delay. This is printed on any motors certified by the NAR. the pieces are as follows, given the example:

E15-10W

The first letter indicates the power range, as specified in the table below. The number to the left of the dash is the average thrust of the motor, in newtons. The number to the right of the dash is the approximate ejection delay in seconds starting at the time of motor burnout. The final letter is an optional manufacturer designation for motor or fuel type. Note that letter designating total impulse of the motor specifies an impulse *range*, not an exact total impulse. For example, there are G motors that have anywhere from 90 to 160 NS of total impulse....an Aerotech G42 is rated at 90NS and a G40 is rated at 120NS. Motors with more than either 62.5 grams of total propellant or have more than 160NS of total impulse are considered High Power motors. You must be certified to purchase and fly these motors. Soon, it may also become necessary to have a license to store high power motors.

Andrew Mossberg ( snipped-for-privacy@hypertek.com) recently posted this chart to rmr, which includes approximate propellant weights for maximum impulse motors for each class:

P O W Low High Low High 200 ISP Propellant E Limit Limit Limit Limit Weight R (NtSec) (NtSec) (lbsSec) (lbsSec) (grams) (lbs) = ======= ======== ========= ========= ======== ======= A 1.26 2.5 0.28 0.56 1.3 0.0028 B 2.51 5.0 0.56 1.12 2.5 0.0056 C 5.01 10.0 1.13 2.25 5 0.0112 D 10.01 20.0 2.25 4.5 10 0.02 E 20.01 40.0 4.5 9 20 0.04 F 40.01 80.0 9 18 41 0.09 G 80.01 160.0 18 36 82 0.18 H 160.01 320.0 36 72 163 0.36 I 320.01 640.0 72 144 326 0.72 J 640.01 1,280.0 144 288 652 1.44 K 1280.01 2,560.0 288 575 1,305 2.88 L 2560.01 5,120.0 575 1,151 2,609 5.75 M 5120.01 10,240.0 1,151 2,301 5,219 11.5 N 10240.01 20,480.0 2,301 4,602 10,438 23.0 O 20480.01 40,960.0 4,602 9,204 20,875 46.0 P 40960.01 81,920.0 9,204 18,409 41,751 92.0

Currently, consumer rocketry stops at rockets with a total of no more than 81,920NS of total impulse. Anything larger than that is by definition an amateur rocket.

-------------------------------------------------

1.7 What is a CATO? Is it CATO pronounced KAY-TO or CAT-O?

The following definition has been posted to r.m.r. by Jack Hagerty, ( snipped-for-privacy@rml.com) editor of the excellent r.m.r Glossary. For even more complete information on the term CATO, refer to the glossary.

A motor failure, generally explosive, where all the propellant is burned in a much shorter time than planned. This can be a nozzle blow-out (loud, but basically harmless), an end-cap blow-out (where all of the pyrotechnic force blows FORWARD which usually does a pretty good job of removing any internal structure including the recovery system) or a casing rupture which has unpredictable, but usually devastating, effects. Another form of CATO is an ejection failure caused by either the delay train failing to burn or the ejection charge not firing, but the result is the same: the model prangs.

Opinions on the meaning of the acronym range widely. Some say it's not an acronym at all, but simply a contraction of 'catastrophic' and should be pronounced 'Cat-o' (which sounds better than 'cata' over PA systems :-). Others maintain that it is an acronym but disagree on the meaning, offering a broad spectrum of 'CAtastrophic Take Off,' 'Catastrophically Aborted Take Off,' 'Catastrophe At Take Off' and the self referential 'CATO At Take Off.' The acronym crowd pronounces it 'Kay-Tow', like the Green Hornet's side kick. It has been pointed out, though, that all of the above are 'post-hoc' definitions since LCO's were using the term over range PA systems long before any formal acronym was established.

-------------------------------------------------

1.8 When a consumer rocket motor fails (i.e., CATOs) does it explode or detonate?

To be precise, consumer rocket motors do NOT 'detonate'. Black powder rocket motors 'deflagrate'. Detonation involves the creation of super- sonic shock waves. Use the term 'explode' when discussing CATOs involving split motor casings, holes blown out the sides of models, etc.

-------------------------------------------------

1.9 Why don't I just make my own model rocket motors? Shouldn't I be able to custom-make better, more powerful motors at a cheaper price?

This subject has been hotly debated on r.m.r. It is one of those 'emotional' subjects that find people either firmly for or against.

The bottom line is that rec.models.rockets is primarily a newsgroup for discussing *consumer* rocketry (which covers model rocketry and high power rocketry). Some amateur issues are discussed, but these are not the primary focus of the group. Manufacturing your own rocket motors can be a very dangerous thing to do, unless done properly, and with extreme care. The odds are you will not make motors that are of any higher quality, total impulse, reliability, or cost less than pre-manufactured consumer rocket motors.

It is the opinion of the editor(s) of this FAQ that you should NOT try to manufacture your own motors. If, however, you insist on partaking in amateur rocketry, then the editor(s) of this FAQ urge you to get in contact with an established amateur rocketry group for guidance and assistance.

2.2.3 Miscellaneous suppliers

For those of you who like to buy their tubing, balsa, and other materials in bulk, this section may have the supplier that you are looking for. Also included are suppliers of the kind of goods that many of us find useful for model and high power rocketry. While there are very many sources of materials from which one can build rockets, and there is no way that a list can completely cover this broad category. Here is a list of companies that have been mentioned on r.m.r., or have been recommended to the author. No company listed in this section is a rocketry specialty company. Many of the companies in the preceding sections also sell "raw materials," so rocketry-related questions are best directed to them.

What are some good books to read to learn more about model and high power rocketry?

Handbook of Model Rocketry, Sixth Edition G. Harry Stine Synopsis: THE handbook on model rocketry. Covers just about everything you need to get started. Good tips for experienced modelers as well. Sixth edition was published March 1994. Available from several sources, including NARTS.

Basics of Model Rocketry, 2nd edition Douglas R. Pratt Kalmbach Books, 1993 Synopsis: A general introduction to model rocketry. The 2nd edition is highly revised and has become available as of Jan. 1993. The first edition is very Estes/Centuri/FSI oriented. The second edition includes sections on composite motors, Aerotech, NCR and other more recent manufacturers.

Model Rocket Design and Construction Timothy S. Van Milligan ( snipped-for-privacy@compuserve.com) Kalmbach Books, 1995 Synopsis: 120 pages, 16 chapters, 240 illustrations, 40 photographs; This book is geared towards modelers wanting to know more about the art and science of building better rockets. Includes chapters on design, improving performance, constructions and other topics. The coverage of glider and helicopter recovery, the glossary, and construction and repoir techniques is very good.

69 Simple Science Fair Projects with Model Rockets: Aeronautics Timothy S. Van Milligan ( snipped-for-privacy@compuserve.com) Published by Apogee Components ISBN 0-9653620-0-0 Synopsis: 104 pages pages consisting of 5 chapters and 3 appendicies; including 83 illustrations. Soft cover with 4-color artwork. This book contains topic ideas for rocketry related science fair projects from very simple experiments that can be done in an afternoon, to some complex ones that require more sophisticated measuring equipment. Each project begins with some background information that explains why the topic is important and should be researched. Most projects also give a starting point that tell what type of equipment may be needed, and also where the experimenter should go for additional background research. This is not a cookbook approach, as the actual experiment must be designed by the researcher.

The Model Rocketry Handbook Stuart Lodge Argus Books 1990 ISBN 1-85486-047-X Synopsis: British handbook on model rocketry. Geared towards beginners, but some good tips for more experienced rocketeers.

Stu's Space: The Gospel According to Stuart Lodge Stuart Lodge 25 Huntington Drive Castle Donington Derby DE74 2SR U.K. Synopsis: A more advanced book than his "The Model Rocketry Handbook".
