Dear readers

We really need your help with an important thing. You can read more about it further down the page.

Parachute test this Saturday

We are planning a new manned parachute test this Saturday morning at Center Jump, Odense Airport.

This time we are testing an (obvious) modification we made to the reefing system.

In previous tests, the box containing the timer/cutter was hanging loosely on the reefing line it was supposed to cut.

This gave the us the risk of an entanglement, which we would of course like to minimize. Therefore, we have now added a pocket on the parachute for each of the two boxes, which is meant to minimize the risk, and it is this modification that we aim to test.

Furthermore, we have been donated a parachute, which in its design is very close to what we are aiming at using on the manned space capsule. furthermore, we got two mechanical reefing systems that we would also like to test. Unfortunately, the versions we got were only with a timed delay at 4.5 seconds. This means that the parachute will not have stabilized its descent speed before continuing its inflation. This will certainly make for a – let’s call it interesting – opening for our skydiver. But he has most like tried things that are worse than this.

The Ring-slot parachute that we are testing this Saturday

We invite you to drop by and watch when we prepare the equipment, take off and land again. Perhaps we could also use a couple of extra eyes when we are trying to locate the parachute on its lonely way back to Earth, after our skydiver has released at 1,500 metres altitude.

After landing, we will certainly also show the video from the jump in the club house to all who are present.

The first time we went to Center Jump, we had some difficulties finding the club house, so here’s a little help for you: Map to the club house.

The weather forecast is still changing a bit with regards to cloud cover, but at the time of writing, it looks to be okay for the two planned jumps.

The predicted direction and speed of the winds at various altitudes have been pretty constant over the last many days, so here’s a guesstimate on the course over ground, if the wind remains as currently predicted.

The predicted course over ground for the two parachutes.

The red line shows the predicted path for the first jump with the C9 parachute – the one we have used many times before. The yellow line is the predicted path for the ring-slot parachute, which we expect to have a higher descent rate, and thereby a shorter path. There is quite a bit of uncertainty related to this particular calculation, since we don’t yet know the exact characteristics of this parachute.

 

Support this summer’s rocket launch!

We REALLY need your help with an important thing.

You see, we have started an indiegogo campaign, which will finance the costs related to the launch of the Nexø II rocket. the primary focus of the campaign is that you can get your portrait on the rocket, thereby indirectly fly with it yourself. There are also other opportunities, all the way up to paying for your own payload on the rocket and to become the main sponsor of the live stream!

Our monthly donors are pre-qualified to get their portrait on the rocket, as long has they have supported us for at least three months by 15 June. Our supporters will get a mail on how to proceed.

Nexø I and Nexø II

we kindly ask you to mention, like, share and USE the Indiegogo-campaign, so that we can get the word out, that Copenhagen Suborbitals is still launching rockets from the island of Bornholm in the Baltic Sea, working towards launching an amateur astronaut to space in a home built rocket -built in the member’s spare time, crowd funded and supported by companies helping and donating.

ad astra,

Mads
