How a Rocket Engine Works

A great easy to follow video from CS for those not familiar with how a liquid-fueled rocket engine works.

Video Caption: This video describes how the regeneratively cooled LOX / Ethanol engine used in the HEAT-2X rocket works.

CS Kick Off Work on Full Size Capsule

The team have started the year with the build of a boilerplate capsule in order to help with hatch and window placement and optimal astronaut position.

The first iteration of the capsule model has two purposes: The first is to experiment with how the astronaut will be positioned in the capsule. Before Christmas we held a meeting in the capsule group. Our own “Space Historian” Carsten Olsen gave us a lecture on the history of astronauts from the earliest space missions (Gemini, Mercury) to the current (Soyuz) and to the future (Blue Origin, Dragon, Space X). We learned how the different missions have solved the challenges of getting an astronaut safely into space and back to earth (or the ocean as it was on US missions).

Once we’ve placed the astronaut, we can investigate what will be the best location for the hatch, as well as the location and size of “windows”. This gives us a good starting point for the next iteration, where we will look into the right materials and manufacturing processes.

And of course to help get the public behind the project.

The other primary purpose is to provide a PR platform, which will give us the opportunity to show the public what we’re working towards. Now that we will have something that is the right size, we might as well paint it and make it look “real”.

Hopefully, an increased public awareness will inject some interest and dollars so we can see the ball start rolling faster.

CS 3-Cluster Parachute Test

Nexø II Swing Test

No Nexø II Flight This Year

The Nexø II rocket remains grounded on land until summer of 2018, the board of Copenhagen Suborbitals has just decided.

Launching a rocket is a large-scale project. A lot of different parameters must be fulfilled in order for the Nexø II mission to be optimum, and this year it has simply not been possible due to both internal and external delays combined with bad weather conditions.

Next week was our last launch window but one of our stakeholders was not able to be there
during the launch and we couldn’t get the airspace cleared.
That’s why we have now finally decided to exercise due diligence around the project, hence postponing the launch of Nexø II for weather conditions again to be favorable.
The mission is still on, and we are launching Nexø II in the summer of 2018.
Until then, you can see the Nexø II rocket in the Copenhagen Suborbitals headquarter at Refshaleøen in Copenhagen.

Disappointing to read this, and is not the first time this has happened, Nexø I was delayed from 2015 to 2016. Being constrained to one season of the year with an ocean-based launch infrastructure does not really help the flight rate.

I do not doubt the team’s long-term commitment to putting a person into space but the pace will have to change to keep the general public interested for the long haul.

Cop Sub to Launch Nexø II this Weekend

Updated 5/9/2017 – Dates updated

Copenhagen Suborbitals will launch their Nexø II rocket this weekend, 9-10th September.  23rd September with the 24th as a backup.

The original press kit post can be found here.

The rocket differs from Nexø I, launched last year, in the fact of having an onboard pressurization system rather than a blowdown system.
The rocket is 0.3m in diameter and 6.7m long and is expected to reach approximately 14km in altitude.

Altitude though is not the primary objective, a successful flight, and recovery, thus testing all systems will be seen as a win.

You can follow the launch here making sure to connect with the team on social media where updates will be more thorough.

Good luck to the team and wishing for a successful launch and recovery.

Status in Copenhagen Suborbitals

Copenhagen Suborbitals is the world’s only manned, amateur space program, 100% crowdfunded and nonprofit. In the future, one of us will fly to space on a home built rocket.
