Mission One: Drop Tests From Tethered Balloon
Components
Payload Construction
- Restrung Parafoil Kite (bought off ebay) using design and measurements from The Black Rainbow. As can be seen the parafoil lines are brought up to 2 wooden bars which have servo horns glued on allow it to be attached to the payload. Therefore by turning this bars you actually change the parafoil's angle of attack.
- Built payload
- Blue foam cut with hot wire cutter into T shape to lower the centre of gravity
- Servos added to the cross bar, battery pack and radio receiver placed lower down.
- Adapted R/C Transmitter so that both sticks were in the vertical plane (as each controls one servo). This was achieved by hacking up the controller and gluing the stick in place.
- Test video can be seen here
Testing
- Drop tests from a tethered balloon.
- Changed Parafoil to Steve's and instead of adjusting the angle of attack we directly attached most of the lines to the payload and used the servo + bar to control the break lines.
- Managed to get some degree of control
