If people havent seen it:

Work in preparation of the june launch of HEAT 1X is progressing steadily.

At HAB the Sputnik launch pad is being prepared. Rocket Booster is already assembled. Last Sunday we made a series of crucial tests with the notorious LOX valve which let us down last year.

HEAT 1X got up steam with - 196 C degrees cold liquid nitrogen - and all abnormalities of the valve could be tested under realistic launch conditions - just as when it is for real.

See video of the test here:

http://www.youtube.com/watch?v=52ytbD6pnLc

The short version is that the valve is now rock steady. All the times we've asked it to open, it opened exactly as it should. Insulation, new heating elements, and a complete cleaning of the valve has worked. Finally, we now use helium to operate the actuator instead of air. This gas, we have in a clean and perfectly dry form. The actuator control air valve, and helium tank kept at around 40 degrees of heating elements which only uses about 100 watts. This despite the fact that the nearby LOX tank is at - 196 C. It works!

To get to the point...

Sputnik platform has installed two engines - by using a gold transfusion from CSS, our support club, have gear and propeller. To visit them and join the force that is with us - go to http://www.raketvenner.dk

In the last week of May 2011 Sputnik will take off on its maiden vouage as self-propelled missile frigate - headed for Spaceport Nexø, Bornholm.

This transport operation is independent of the launch - the only job the crew has is to get themselves and Sputnik safely to Nexø. We expect a speed of 5 to 6 knots - equivalent to just under 24 hours journey. Sputnik will not be alone, but is escorted the whole way by a former lifeboat at 4 x 17 meters - which can take Sputnik in tow if something fails. It is a ship built for rescue operations at sea - big, solid and with 1000 Hp. Built in Germany in 1965. Now owned and under the command of one of CS's faithful yactskipper members.

(Sputnik support ship / booster recovery ship)

As of June 1, Sputnik and her escort vessel should be ready in Nexø.

Here we meet with hume guard cutter MHV 903 Hjortø. Again this year she will be assisting the operation at sea.

Launch window is set for June 1 to 15, and given the ok from SOK. Farvandsvæsnet sends notice to Mariners - and per. radio via NAVTEK - and Teletext page 428.

At the first prospect of good weather, which is within the requirements we must meet - the rest of the team will move to Nexø. We send notice of the launch 24 hours before - and it gives all the necessary CS people time to get over - and CSS can put the champagne on ice and start preheating sequence for the victory cigars. CSS will make a special event on launch day two places in the country (no details ready yet).

More on this at http://www.raketvenner.dk when the time is approaching.

The operation is covered by ing.dk and TV-2 (Denmark) who will do everything possible to make sure that everyone knows as much as possible about what is happening. All our video feeds from the rocket and Sputnik along with our radio communications - the same happens here at Ing.dk - so whether you like TV or the internet, there should be good professional media to cover what is going to happen.

Picture: http://ing.dk/modules/xphoto/cache/1/55 ... _0_0_0.jpg

(Nominal weather - Sputnik ready)

Early morning on day X, launch day, Sputnik departs with HEAT. She is under the command of Kristian Sorensen on the voyage - he is certified Yactskipper and is being assisted by a competent crew of three. Sputnik will be escorted by the same vessel as the voyage from Copenhagen.

As last time, Andre Christensen - Standard Flex / Inspection Ship man, is head of maritime operations - particularly around the fast small salvage craft.

Close to the position 55 03 N 15 36 E Sputnik meets with MVH 903. Within a safety distance of 8 M only Sputnik, her escort, and MVH903 will be located. Furthermore, we have two fast RIBs, one red, which is from MVH903 and one blue. The blue RIB is under command by Flemming Rasmussen.

Picture: http://ing.dk/modules/xphoto/cache/1/55 ... _0_0_0.jpg

(Red rib, photo Marine Home)

During launch, both the two large vessels will be located between 2500 and 3000 meters from the unmanned Sputnik, while both the two RIBs are closer. The red RIBs mission is to assist in the salvage of the capsule, while the blue RIB assists in salvage of the burned out rocket booster. RIB ensure that the booster may be under tow of Sputnik escort vessel.

All cameraa at Sputnik now have runtimes of more than one hour. HEAT's new cooling system allows it to be fueled and pressurized, ready for firing up to over an hour. Pressure in all tanks, LOX valve position - and a quantity of data as well as three video links can be monitored live in Mission Control at MHV903. All these downlinks is received with high gain antennas onboard MHV 903 Hjortø - and linked to TV-2 and Ing.dk.

We evacuates Sputnik when refueling and pressurization is complete. In principle, Flight then can send the signal to launch Sputnik, and sixty seconds later liftoff will happen. Flight has an hour to get the bird in the air. In principle, the touch of a button. In principle. In practice, the tracking radar, us from the booster, FIDO, weather, range safety, and a few other lights heve to be green before he can send the firing command to HEATs own mission sequencer.

FIDO covers a system which downlink data from the launcher inertial platform. It is developed by Flemming Nyboe and Steen Andersen. From these data the impact is calculated during the entire flight. Should this move outside of predetermined limits, Flight may chose to abort the mission. He can turn off the engine, he can separate the spacecraft from or deploy parachutes. All of which will limit HEAT´s downrange dramatically.

There are many uncertainties that take into account when calculating the rocket's flight. It must work in an environment that is much more changing and complex than the small solid rocket normaly by HPR perople - so it is hard to achieve the same accuracy as can be done with small rockets. Therefore it is also a big feature that we can actively intervene to change the mission while it is running.

This is quite far from what I know from launches with ordinery HPR people.

Here's HEAT nominal mission:

T-60 sec - auto sequence starts - Flight sends the launch code to HEAT.

At Sputnik an audible alarm´starts. If someone, for whatever reason is still onboard, they have 52 seconds to press an emergency stop and abort the launch. Otherwise they will be blown away when HEATs 160,000 hp are unleashed.
It is not realistic that someone is forgotten - but the code could be sent in error - and so it is possible to do a manual abort on the pad.

T-8 sec, igniters 1 to 4 is fired at 0.1 sec intervals.

T-0 sec, LOX valve opens, ignition!

Picture: http://ing.dk/modules/xphoto/cache/1/55 ... _0_0_0.jpg

(Same situation, but in static tests)

T +0.05 sec, HEAT develops nominal thrust of 65 kN, and we have liftoff.

T +0.9 sec, tower clear, speed is 27 m/s or around 100 km/h

T +1.0 sec, HEAT is now free of the guide rail

T +8.5 sec, the sound hits Mission Control.

T + 16.2 sec, HEAT goes supersonic. The altitude is 3000 meters or just over 9000 feet. The aerospike must now form a shock front so the air "sees" Tycho as a cone tipped object. At TYCHO's tip there mayl be formed a haze of air as the dramatic pressure change precipitates moisture.

Picture: http://ing.dk/modules/xphoto/cache/1/55 ... _0_0_0.jpg

(Same phenomenon in the Ares 1X test. Photo: NASA)

T + 20.7 sec. Max Q. Point of maximum dynamic pressure. This is the point where the dynamic load on HEAT 1X peeks. Here is the drag is 7400 N and if HEAT at T + 20 sec is still in one piece it should survive all the way to burnout.

T + 30 sec, MECO - burnout. The height is now 8,800 meters and the speed almost half a kilometer per second - 464 m / sec. At this rate, it takes ten seconds to get from the planetarium at Sortedams lake to HAB at Refshaleøen.

The next 40 seconds - HEAT will coast without thrust due its large inertia towards its apogee in its ballistic trejectory.

T +70 sec,the burned out HEAT booster will separate from the spacecraft Tycho Brahe.

The process can be followed with both two on board camera that sends live TV down, and with a special ground-based infrared camera which is radar guided, and is part of the package of instrumentation from Weibel Scientific.

We also have three GoPro camera on board filming the process inside the capsule, on the side of the booster and the launch pad.

In the two RIBs we have several cameras, both still picture and high speed cameras filming the lliftoff up close.
At the moment the booster is separated, it will deploy a 30 meters long black and white streamer - which generates so much air drag that it will slow the booster down and turn it into a tail first direction. This reduces the boosters ballistic coefficient, and means its trajectory will be slightly shorter than Tycho's

T + 72 sec, both rocket parts is passing the trajectorys highest point - 17,800 feet above sea level - 53,000 feet - high up into Earth's stratosphere.

Picture: http://ing.dk/modules/xphoto/cache/1/55 ... jpg(always good weather, nice views)

T + 80 sec, Tycho currently flying solo deploying a small pilotchute of only 0.15 m2, this draws a drogechute of 2 m2 out of its chamber on the side of Tycho's parachute module. This is specially built for unfolding at extremely high airspeed.

T + 90 sec. The three big orange parachutes are now deployed from the Tycho capsule. This all happens in very thin air high up the atmosphere, so speed is reduced gradually. The next minute Tycho gradually slows down to just 10 m/sec

At the same time the boosters three chutes are also unfolded - it happens at the same time - but somewhere else in airspace.

Picture: http://ing.dk/modules/xphoto/cache/1/55 ... _0_0_0.jpg

(Same principle as this. Photo: NASA)

The booster has a significantly higher descent rate and impact on the ocean with fins first around T +5 min. Tycho takes longer, but should make a beautiful touchdown with its three large orange and white chutes.

G-load at impact - and all the way up and down, is measured together but a lot of other data onboard. Based on the measurements we can assess whether a person could have the trip.

The two rib boats will find and secure both the capsule and the booster. Touchdown of these objects will happen roughly in the same area, so we hope that the radar tracking of Tycho will help the booster recovery people as well. Both booster and spacecraft are built so they have plenty of buoyancy.

Sputnik crew returns to the platform right after launch to prepare it for the return to Nexø.

Sputnik escort will tow HEAT to port and we hope it can be brought aboard Sputnik on the return trip to the HAB.

Tycho is salvaged by MHV903. According to tradition we should use an aircraft carrier task force - but we think MVH903 according to Danish standards is about the same.

I hope you cross your fingers for us - we need all the luck you can get in this world.

Thanks,

Peter Madsen

I cant help but wonder about the name "Copenhagen Suborbitals" Surely this will need to be addressed if they are to ever go orbital?!

What if they move to New Mexico and go Orbital or something?

Well, the only item made by Microsoft that I'm currently using is a mouse, which is not software, and it's not made by a small company. So they could just keep the name. And anyway, this seems to me to be more of an art/engineering project than an attempt at starting a commercial enterprise, so I'd be very surprised if they ended up launching an orbital rocket from New Mexico...

Hi

CS has just had a perfect full countown test of all systems except fuel. The valves and other keay components are now monitored and their status is shown on the control screens. LOX was loaded and testet, ignition was tested and all camera downlink etc. performed well too. All persons involved in the launch have gotten a small laminated card telling them all their tasks.

They are now ready to go to Bornholm this weekend.

The only major worrys now is the loss of the follow ship for the weekend due to an engine faliure and the always changing wether in Denmark. The rocket cant launch in rainy wether because of ice buildup and because the downlink antenna is manualy guided and the rocket trajectory cant be followed in clouds.

Right now there is a lot of guessing but you can follow the mission live at this link (in Danish). There is a live chat and news from the mission.

http://ing.dk/live

The weather report is looking good for friday but nothing is certan.

from the live chat:

'We expect the launch to take place between 12:00 and 16:00 GMT+2
by Martin Højriis Kristensen at 6/1/2011 8:37:32 AM10:37 AM

The target launch date right now is Friday. The launch will be postponed if the weather conditions are not suitable for launch, but right now it is our best guess.
