Parts / Assembly - PARACHUTE
Like a protective parent you only want the best for your payload, so when it comes to dropping it from over 30 thousand metres it’s important that a bumpy landing isn’t on the cards. Worry not you’ll find exactly what you need here. Our parachutes are designed and tested with near space flight in mind; now used on all our launches they give us peace of mind regardless of our payload spec.
When it comes to parachute deployment the SentIntoSpace mantra still applies as appropriately as ever – ‘the simpler the better’. We adopt a 3 stage system: balloon, parachute, payload – see image below.
During the ascent the parachute is pulled taught by the balloon and therefore has a relatively narrow profile, making it less susceptible to crosswinds. When the balloon bursts the parachute is released and the canopy able to open and spread. All in all the assembly is simple, all that really needs to be considered is the distance used between the payload and the parachute and the parachute and the balloon.
LAUNCHING IN LOW TO NO WIND (RECOMMENDED)
Wind conditions on the day significantly affect both the ease of launch and the likelihood of you encountering a problem. We recommend launching in very low wind conditions but understand this is not always possible.
Ultimately we want to try and maximise the suspension line from the balloon to the parachute (see above image). This means that any movement by the balloon is dissipated before it reaches the parachute and payload. In short the longer the line the less jerky the footage. Of course we don’t want to go too long as this can reduce control when launching.
LAUNCHING IN HIGHER WINDS (NOT RECOMMENDED)
If wind is not of your side on the day don’t be afraid to postpone the launch! If you’re going to plough on regardless then you might want to think about shortening some of the suspension lines. This makes the payload less likely to swing uncontrollably into the ground when you release it.
- Securing lines can be as simple as knotting them together – just make sure they’re secure (no rushing!).
- Ensure the payload is level when suspended – shorten or lengthen lines to get the angle you want for your camera.
