GENERAL GUIDELINES

The Aerospace project is broken into three separate areas and the 4-Her will be enrolled in the project by their grade level in school. The 4-Her may complete the Aerospace project by entering in any one, two, or all three of the following areas: rocket construction (in grade 3 the 4-Her must do the construction option to complete the project with the poster and flight contest being optional), Aerospace posters, and rocket flight contest.

All 4-Hers must do 3 activities from the grade appropriate manual. At least 2 must be from the required activities. Manuals will be checked for completed activities at either the pre-judging workshop or at the judging when the member checks in. If these activities are not completed by judging check-in the 4-Her will be allowed to exhibit but will not be eligible for Champion or Reserve Champion in any of the aerospace categories. The member’s parent/guardian, the 4-H club leader and one of the aerospace leaders must sign the Aerospace Rocketry Record sheet AB-19. The aerospace leaders will be signing completed record sheets at all workshops and the pre-judging workshop (only completed record sheets will be signed, blank record sheets will not be signed). The aerospace leaders will not be signing record sheets the day of aerospace judging due to the busy nature of that day.

Only rockets from the construction option and posters of the aerospace project will be displayed at the county fair. There will be no flight contest rockets on display at the county fair unless they were in the construction judging also.

ROCKET CONSTRUCTION CONTEST GUIDELINES

All rockets in the construction option must be built according to the National Association of Rocketry (NAR) Model Rocket Safety Code found in the National 4-H Manuals and AB-25. “Ready-To-Fly” (RTF) or pre-finished rockets are not allowed.

The 4-Hers must bring the instructions and face card from the bag or box for the rocket they have built, in case there is a question why a certain building technique was used and to verify the skill level is correct for the grade the 4-Her is enrolled in. All rockets must be constructed and finished (painted) by the 4-Her.

In grades 8-12 the 4-Her should go through a very carefully thought out process when selecting the rocket motor(s) and impulse-ratings for their new rocket design or up-scale. Motor selection is a very serious aspect of rocketry and great care must be taken in this area since the rocket is of a new design created by the 4-Her. The 4-Her should contact the Aerospace Leaders if they have any question as to what motor(s) to use in their new design.

All rockets in grades 3-8 must have a minimum diameter airframe (body tube) of .9 inches (approximately equivalent to Estes BT-50 body tube), and must have a motor mount (including a motor hook or motor retaining system) that you assemble and install in the airframe. Information regarding the airframe diameter of your rocket is on the face card of the kit. Decals are not required in grades 3-5; decals are required in grades 6-12. Plastic fins, either individual or prefabricated fin cans, are not permitted in grades 3-8.

Stage II Juniors Grades 3-5, One rocket selected for State Fair- BU-6843 & AB-04

Grade 3, Rocket Construction, Skill Level I Rocket Kit

1. The required rocket for the construction option in grade 3 is a rocket kit named the Astro 1. The kit is a clone of a classic rocket and is available only by ordering from the Tippecanoe County Extension Office.

2. There will be a workshop held by the Aerospace Leaders to build the required rocket for grade 3. If for any reason you cannot attend the workshop you can build the required rocket on your own. This workshop is only meant to give the 4-Her the opportunity to build their rocket under expert supervision and to gain knowledge of building techniques they might not otherwise experience. The kit is a Skill Level I degree of difficulty rocket. See AB-15 for details.

Grade 4, Rocket Construction, Skill Level II Rocket Kit

1. Rockets for grade 4 must be skill level II or higher.

2. The suggested rocket for the construction option in grade 4 is a rocket kit named the Cherokee D. The kit is a Skill Level II degree of difficulty rocket. The kit is a clone of a classic rocket and is available by ordering from the Tippecanoe County Extension Office.

3. There will be a workshop held by the Aerospace Leaders to build the suggested rocket for grade 4. This workshop is only meant to give the 4-Her the opportunity to build their rocket under expert supervision and to gain knowledge of building techniques they might not otherwise experience. See AB-16 for details.

Grade 5, Rocket Construction, Skill Level II or III Rocket Kit

1. Rockets for grade 5 can be either skill level II or III, skill level III rockets will generally score higher because of the increased difficulty in construction.

2. Rockets for grade 5 can be either a commercially packaged kit, or a replica of a rocket from an old catalog.

3. Single stage or multi stage rockets are allowed in grade 5.

4. When exhibiting rockets that use D or E impulse-rating motors, the rocket must meet the following criteria. The rocket must be single stage. No multi stage rockets using D or E impulse-rating motors. The rocket must have a minimum diameter airframe of 1.3” (approximately equivalent to Estes BT-55) with a minimum main airframe total length of 18 inches including nose cone, and tail cone, but not including fins. Rockets using a cluster of A, B, C, and D motors are allowed.

Stage III Intermediates Grades 6-8, One rocket selected for State Fair- BU6844 & AB-05

Grades 6-7, Rocket Construction, Skill Level III, IV or V Rocket Kit

1. Rockets for grade 6 can be either skill level III or IV, and for grade 7 can be either skill level IV or V. The higher skill level in each grade will generally score higher because of the increased difficulty in

2. Rocket kits for grades 6-7 can be either a commercially packaged kit or a replica of a rocket from an old catalog. Multi stage and rockets using a cluster of motors are allowed. Upscale versions of lower skill level kits such as skill levels I, II or III are allowed and will be considered as a skill level IV or higher rocket.

Grade 8, Rocket Construction, No Skill Level

1. The objective in grade 8 is for the 4-Her to design, and fly a Model Rocket of their own creation. The rocket should not look like any actual rocket or missile (example those built by NASA). This rocket is to be constructed from a package of materials, called The “Bag-O-Parts”. This package is available only by ordering from the Tippecanoe County Extension Office. Use your imagination, your rocket should be more than just fins and a nose cone on an airframe, and should not bear much resemblance to rocket kits available in stores. The 4-Her must use only the materials supplied in the parts kit, and the rocket built must be for the construction judging first with the flight contest being optional. See AB-05 Stage III the grade 8 section for more information. Also see AB-29 for instruction, and guidelines for designing a new rocket for grade 8.

2. The 4-Her should develop a very simple a set of basic instructions that another rocketeer could follow and build the new rocket design. These instructions must accompany their rocket for construction judging.

Stage IV Seniors Grades 9-12, One rocket selected for State Fair- Bu-6845 & AB-06

Grades 9-12, Rocket Construction - Skill levels vary see description below

1. In grades 9-12 the 4-Her may do any one of the following: a rocket design created by the 4-Her, a commercially packaged kit skill level III or higher, a scratch built replica of a rocket from an old catalog skill level III or higher, or an up-scale replica of another commercial rocket kit.

2. The use of balsa wood, basswood, light plywood, high strength plastics such as G10, or any structurally sound, non-metallic material is suitable for fins or wings.

3. Multi-stage and rockets using a cluster of motors are allowed.

FLIGHT CONTEST GUIDELINES

All launches in the flight contest will be done in accordance with the NAR (National Association of Rocketry) Model Rocket Safety Code found in the 4-H Manuals and AB-25. All rockets in the flight contest must have been built by the 4-Her and in grades 3-5 must meet the construction criteria for the grade in which the 4-Her is enrolled. The 4-Her does not have to fly the same rocket that they exhibit for the construction option of the project (except grades 3 & 8, please see below). “Ready to Fly” (RTF) or pre-finished rockets are not allowed in the flight contest. The 4-Her must perform their own launch in the flight contest.

A variety of items will be needed for participation in the flight contest, such as igniters, parachute wadding, baby powder and rocket motors, just to name a few. The aerospace leaders will provide the launch pads and controllers for flying.

There are no State Fair selections in the Flight Contest. Information about the State Fair Aerospace Challenge is available from the County Extension Office or the Aerospace superintendents.

If the 4-Her has any questions as to what motor(s) to use in any portion of the flight contest they should contact the Aerospace Leaders for advice, information, and suggestions on motor selection. Their phone numbers and email addresses are at the beginning of this project section.
