In the last lesson, we discussed the ideas of using flat-hulled boats and round with keel hull boats for balloon-powered boats. These designs were explored as options for maximizing efficiency and speed in a balloon-powered boat.
For my potential design, I would like to create a round with keel hull boat. This design allows for better maneuverability and stability in the water. It also helps with reducing drag and increasing speed.
To modify the design, I plan to add a smaller, removable keel at the bottom of the boat to ensure better stability and keel effect. I will also make sure that the round shape of the hull is streamlined to minimize the resistance of water.
The materials I have readily available are cardboard, duct tape, a few small wooden dowels, a thin plastic sheet, a balloon, and a pair of scissors.
To build my boat, I will need the following equipment:
1. Scissors for cutting the cardboard and plastic sheet.
2. Duct tape to securely connect all the components.
3. A ruler or any straight edge to help create straight lines for cutting.
4. A marker or pen to mark measurements on the materials.
Using these materials and equipment, I will construct a round with keel hull boat by cutting out circular shapes from the cardboard for the top and bottom of the boat. I will attach the two circular pieces together using adhesive and tape to create the rounded shape. Then, I will cut a small rectangular keel shape from the cardboard and attach it underneath the bottom of the boat, ensuring it is securely placed in the center.
To ensure the boat can move forward, I will attach a small wooden dowel to the rear of the boat, creating a place for the balloon to be attached. The wooden dowel will act as a guide for the balloon's propulsion.
Once the basic structure is ready, I will cover the boat with a thin plastic sheet to make it more waterproof and reduce friction with the water.
Overall, this design aims to combine the round with keel hull concept with the available materials to create a lightweight and streamlined boat for efficient balloon-powered propulsion.
To review the ideas of a flat-hulled boat and a round with keel hull for balloon-powered boats, let's first understand their basic characteristics:
1. Flat-hulled boat: This design features a flat bottom hull, which provides stability and ensures that the boat can move in a straight line. It is suitable for calm waters and is simple to build.
2. Round with keel hull: This design consists of a rounded hull with a keel at the bottom. The keel provides stability and prevents the boat from tipping over. It allows for better maneuverability in rough waters and allows the boat to go against the wind.
Both designs utilize the power of a balloon to propel the boat forward. By releasing the air from the balloon, it creates a force that moves the boat in the opposite direction.
Considering a potential design based on these ideas, the following is a sample description:
Design: Round with keel hull
Modification: Add a rudder for better steering control. This can be accomplished by attaching a small fin-like structure at the aft end of the boat, which can be adjusted to direct the boat's course.
Materials:
1. Lightweight and water-resistant material for the hull, such as foam board, plastic sheet, or lightweight wood.
2. Balloons of various sizes.
3. Adhesive, such as glue or tape.
4. A small piece of metal or plastic for the keel.
5. Wire or string for the rudder.
Equipment:
1. Scissors or a craft knife to cut the materials.
2. Measuring tape or ruler for precise measurements.
3. A marker or pencil for marking the measurements on the materials.
4. A heat source, such as a hairdryer or heat gun, to inflate the balloons.
With these materials and equipment, you can achieve a round with keel hull design and modify it with a rudder for better steering control. Remember to adjust the materials and design according to what is readily available to you.
