Design principle
To build a successful blimp, you need to follow some basic design principles.
Design principle involves two aspects:
- Payload estimate and checking: Whether the designed airship can be effectively suspended in the air.
- Motion primitives checking: Whether the designed blimp can effectively move in the 3D space
Please use following checkbox to see if your design satisfy these principles:
Principle 1: To allow the designed airship to maintain neutral buoyancy in the air. You need to make sure the following equation satisfied:
where,
-
\(F_B\) is the buoyancy produced by your designed airship
-
\(m_{total}\) is the total lifting capacity of your designed airship
-
\(m_{total} = m_{elec} + m_{envelop} + m_{sup} + m_{payload}\)
The lifting capacity can be divided into the weight of electronics, balloon envelope(Note: this is not something you can ignore), support materials and payload.
Principle 2: To satisfy the needs of exploring the space, your design needs to satisfy the basic motion primitives:
- Maintaining forward speed. The blimp should be able to maintain a desired constant forward speed while having zero vertical speed and zero yaw angular speed.
- Changing altitude: The blimp should be able to ascend or descend to the desired height.
- Changing orientation: The blimp should be able to spin in place so that its yaw angle can be stabilized at any desired value.
