Monash Aerospike

This deserved a post on its own.
I found a couple more video’s of this 3D printed aerospike online which go into a bit more detail.

Of note, the engine has multiple internal chambers, which in the future could be used for thrust vector control, as well as the regen cooled chamber, the spike is also cooled. The engine burns Methane and Gaseous Oxygen producing a thrust of 4kN or 1000lbf, the video below shows a burn time of 60sec.

More info on the project can be found here and here.

Galactic Aztec Mk II Launch This Weekend

Students of the SDSU Rocket Project will be launching their Galactic Aztec Mk.II rocket this weekend, September 16th.

Powered by an Atlas LR101 vernier engine, the rocket is expected to reach 31,000ft.

You can follow the team and launch on Facebook and Instagram.

Monash Students Test 3D Printed Aerospike

Although Aerospikes are not new, what is different about this is the fact that it has been 3D printed where the builder is able to play around with complex geometries not able to be manufactured using conventional methods.

Click the picture below to see the testing video.

This particular engine has made use of printing for the nozzle geometry and embedded cooling network as stated in this article.

Launch of Skybolt 2

The rocket was restricted to 4000ft altitude but looks like it all went off without a hitch. Not sure about successful chute deployment, the slow-mo video appears to show the chute shred from the fin can stage.

The Guardian also did a nice article which can be found here.

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.
