When cutting out the rocket fins, it is not important to cut out the notch.

True
False

Correct Answer

A. False

Explanation

Cutting out the notch is important when cutting out the rocket fins. The notch helps to stabilize the rocket during flight by creating a surface for the air to flow smoothly over. Without the notch, the rocket may experience instability and unpredictable flight patterns. Therefore, it is necessary to cut out the notch when cutting out the rocket fins.

The chute wadding protects the parachute from burning when the engine ignites.

True
False

Correct Answer

A. True

Explanation

The chute wadding is a material that is placed between the engine and the parachute. Its purpose is to protect the parachute from the intense heat and flames that are generated when the engine ignites. Without the chute wadding, the parachute could be damaged or even burned, rendering it ineffective. Therefore, it is true that the chute wadding protects the parachute from burning when the engine ignites.

Rockets were first used as

Ceremonial fireworks
A form of transportation
Instruments of war
Hunting tools

Correct Answer

A. Ceremonial fireworks

Explanation

Rockets were first used as ceremonial fireworks because they were invented in ancient China during the Tang Dynasty for entertainment purposes. These early rockets were filled with gunpowder and launched into the sky to create colorful explosions and loud noises, adding excitement to festivals and celebrations. Over time, the technology of rockets advanced, leading to their use in transportation, warfare, and scientific exploration. However, their initial purpose was to bring joy and awe to special occasions.

When constructing the air frame, the paper should be glued to the plastic tube.

True
False

Correct Answer

A. False

Explanation

The correct answer is False because when constructing the air frame, the paper should not be glued to the plastic tube. Gluing the paper to the plastic tube would not provide a strong and secure connection. Instead, other methods such as using tape or adhesive specifically designed for bonding paper and plastic should be used to ensure a proper construction of the air frame.

The shroud line needs to be cut into

Fourteen 6" pieces
Four 6" pieces
Six 14" pieces
Six 4" pieces

Correct Answer

A. Six 14" pieces

Explanation

The shroud line needs to be cut into six 14" pieces. This means that the shroud line should be divided into six equal parts, with each part measuring 14 inches in length.

The shock cord will be attached to the nose cone using the

Air frame
Launch lug
Parachute
Screw eye

Correct Answer

A. Screw eye

Explanation

The shock cord will be attached to the nose cone using a screw eye. A screw eye is a small metal loop with a screw thread that can be easily screwed into the nose cone. This provides a secure attachment point for the shock cord, allowing it to absorb the shock and tension during the launch and descent of the rocket. The screw eye ensures that the shock cord remains firmly attached to the nose cone, preventing any potential damage or loss of the rocket components.

The purpose of the shock cord is to

Launch the rocket
Recover the nose cone
Hold the fins in place
Attach the parachute to the nose cone

Correct Answer

A. Recover the nose cone

Explanation

The purpose of the shock cord is to recover the nose cone. When a rocket is launched, the nose cone separates from the rocket body and falls back to the ground. The shock cord is attached to both the nose cone and the rocket body, allowing the nose cone to be safely recovered. The shock cord absorbs the impact of landing and prevents the nose cone from being damaged. This ensures that the nose cone can be reused for future launches.

In order for the igniter to work properly, the 2 wires should touch each other.

True
False

Correct Answer

A. False

Explanation

The statement is false because for the igniter to work properly, the 2 wires should not touch each other. If the wires touch, it can cause a short circuit and prevent the igniter from functioning correctly. The igniter requires a small gap between the wires to create a spark or heat that will ignite the fuel or start a flame.

The engine lock should extend about 3/8" from the top of the engine mount when finished.

True
False

Correct Answer

A. False

Explanation

The statement is false because the engine lock should not extend about 3/8" from the top of the engine mount when finished. The engine lock should be properly secured and flush with the top of the engine mount to ensure stability and proper functioning of the engine.

Where should the anchor be attached to the rocket?

2" from the top on the inside of the airframe
2" from the top on the outside of the airframe
2" from the bottom on the inside of the airframe
2" from the bottom on the outside of the airframe

Correct Answer

A. 2" from the top on the inside of the airframe

Explanation

The anchor should be attached 2" from the top on the inside of the airframe because this position will provide the most stability and balance to the rocket during its flight. Attaching the anchor on the inside of the airframe ensures that it is securely fastened and will not come loose during launch. Placing it 2" from the top ensures that the weight distribution is optimal, allowing the rocket to maintain its trajectory and stability. Attaching the anchor on the outside or at the bottom of the airframe may result in unbalanced weight distribution and compromise the rocket's performance.

Read through the safety code and check each box indicating that you agree with the statement.

I will use a countdown before launch and make sure everyone is at least 15 feet behind the rocket before launching.
I will launch my rocket at a slight angle from the vertical, pointed away from all observers.
I will wait until the ejection charge has ignited before attempting to retrieve my rocket.

Correct Answer(s)

A. I will use a countdown before launch and make sure everyone is at least 15 feet behind the rocket before launching.
A. I will launch my rocket at a slight angle from the vertical, pointed away from all observers.
A. I will wait until the ejection charge has ignited before attempting to retrieve my rocket.

Explanation

The given answer is correct because it includes all the necessary safety measures for launching a rocket. Using a countdown before launch ensures that everyone is aware of the impending launch and can move to a safe distance. Launching the rocket at a slight angle away from observers reduces the risk of accidents or injury. Waiting for the ejection charge to ignite before retrieving the rocket ensures that it has safely deployed its parachute or recovery system. These measures prioritize the safety of both the launch participants and any observers.
