Congratulations to Copenhagen Suborbitals! And they finally got one of their rockets back by parachute.

Is anyone else concerned that so many people were milling around near the rocket as it was being fueled?

Kickoff for the BPM100 Rocket engine


Copenhagen Suborbitals
Published on Oct 4, 2018

After the successful launch of the Nex° II it's time to move on to the SPICA class rockets. In the coming years the SPICA and it's 100KN engine will be our top priority.  And now we have kickoff - we are aiming to build the first BPM100 engine in 100 days!

Will it have turbo pumps?.

Doubt it.
I hear those things are awfully loud. It glides as softly as a cloud. What's it called? Monowhale!

They dropped that idea years ago I believe, although I never heard why. Would've liked to know which aspects they thought were out of their reach. I imagine it was the prospect of needing to blow up a number of engines to get it right.

They're leaving the option open:

Orbital Machines business case is to supply battery-powered turbo pumps to New Space startups. In recent years, many small launcher launchers have been established and common to many of them is that they are not really able to start a turbopump project. Successful Eivind and Orbital Machines will now become something they can buy.

I think it's a crazy good idea to start a business, but the best part is that CS is a partner / trial canine. If it succeeds in producing a turbopump, CS will receive the first prototype available for free for our BPM100 engine and Spica! In that case, several 100 kg of Spica can shave sharpener shapes and a greatly reduced DPR section. This is something that could potentially be really interesting for CS. Since we prefer not to make the Spica project dependent on another project, Spica is designed to be a pressurized rocket like Nex° II, but if the turbopump is realized, we will be able to change and make Spica some 100 kg easier.

Nex° II debriefing part 3: Flight Dynamics and data analysis vid:

TL;DW: LOX tank pressure too low -> fuel rich operation -> lower thrust + fuel depleted too soon -> lower than expected apogee.
