A scrub for Copenhagen Orbitals

 

Tweeting from their home made submarine has confirmed their initial suborbital launch has been scrubbed due to a blocked oxidizer nozzle.  The oxidizer nozzle controls the flow of oxidizer on its way to mix with liquid fuel before combustion.  It is common with liquid oxygen as an oxidizer to have this nozzle "freeze up" and become blocked.  Usually, some kind of heating element is generally used to "de-ice" the nozzle before launch.  Rumor is those crafty Danes were using a simple hair dryer to accomplish this task.  This could possibly be cause of the failure.  Keep an eye on their website for further developments.

    Launch is most likely going to be delayed until 2011.

The Engineer's Dream Lives: Copenhagen Suborbitals















Look at this picture.  What do you see?  I see a rocket, a water launch pad and a submarine.  Obviously, the submarine is towing a rocket and launch pad out to sea for liftoff.  Who would be undertaking this endeavor?  North Korea?  Iran?  Some other sovereign nation?  Maybe a company?  A large defense contractor somewhere in the world?

The answer is none of the above...all of what you see has been 100% built by hobbyests.  While you and I tinker with our cars in the garage, or add on to our houses, these guys were building a freaking space rocket.

Oh, and that submarine?  They built that too...that was last year's project...and its been to the bottom of the sea off the coast of Sweden quite a few times...they named it "The Nautilus" ofcourse...


It really is impossible not to be impressed by what engineers, on their own, with no management, company or government backing can do.  A typical defense contractor would probably charge billions to make all this...they built this test rocket with $70k.

In 6 days they will be launching a test dummy into suborbital space, hopefully a human in 3 years...the same feat Burt Rutan pulled off a couple of years ago...Keep in mind, Rutan's Scaled Composites is a company, which has received significant funding from the US gov that enabled it to exist in the first place.

These guys work in a shed.  On their own time.  Why?  Because they freaking can!

A lesson all too lost in today's companies where powerpoint engineering is the rule, and actually doing, or making something, anything is deemed too big a risk.

These guys are an inspiration to engineers everywhere.  Will the rocket blow up?  Scrub launch?  Ditch in the ocean?  Be 100% successful? We'll find out in about 6 days...stay tuned...
