Hej! As you might have noticed tomorrow we are going to perform the Drop tests using an inflatable balloon that will help us to drop for the FFU (Free Falling Unit) from approximatively 500 meters.
The two prototypes of FFU are almost ready. Let me introduce you the last components manufactured: the Battery Cage and the Thermal Cutter.
The Battery Cage as you can imagine is a simple cage that will keep the battery attached to to Bottom PCB.
The Thermal Cutter is a small device that will cut a small wire that will deploy the parachute.
Here you can see the Thermal Cutter in action, this was the very first test performed.
Here you can see other pictures of the components and how we manufactured them.
After hard work the past months we are finally seeing our prototypes come to life. The team has finished soldering two bottom PCBs and one top PCB, we’ve made a few hemispheres, made thermal cutter, parachute and I could continue with this list for a very long time. So what is next. Well our drop test is next Thursday, the 19th of April. The team will go from Stockholm and drive for some hours until it reaches our test field. Then the team members will do what they are assigned to do and hopefully everything will run smoothly. The purpose of our drop test is to test our prototypes. Following are the things we intend to test in our drop test:
- Mission mode
- Rocket pin
- Release mechanism for drop test 1
- Parachute deployment
- Thermal cutter
- GPS front end
- GPS commercial
- STX 2
- Beacon transmitter
- Antenna system
- Sensor gathering
- FFU Power System
It will be very exciting to see the results and hopefully, everything works as we want it to work.
Have a nice weekend!
