Updated at. 14:46: Emerald wing, but the nose cone, with all the electronic equipment broke apart shortly after takeoff, probably at a speed of 1650 km / h. In the area rained down on different parts. By Thomas Djursing July 27, 2012 at. 13:26
Shortly after the new parts observed by surveillance aircraft, some in water other in the air. Moieties consist essentially of the residues of the inflatable life jacket to be inflated by a reduction in the water, as well as residues crawler transporter of the parachute.
Data from the flight also shows that all electronics are turned off shortly after the start, crawler transporter then CS people can already likely to say that the rocket's payload, so the important nose cone, crashed crawler transporter shortly after takeoff.
"I can not say with certainty how high the rocket reached, but my assessment is six kilometers. Judging from the rocket's trajectory and engine pressure, so it should follow the calculations we have made in advance, "says crawler transporter Peter Madsen.
Since the payload from the rocket has been lost, the data on height crawler transporter and speed not possible to get verified, but the assessment is that the rocket reached a top speed of 1650 km / h in 690 meters in height, and it's probably the moment that the joint between the rotating the nose cone and the second step is broken.
"Next time we have to build a nose cone in much stronger materials. It may be something to put it on powerful crawler transporter ball bearings or completely drop the rotating top, "says Peter Madsen, who also believes that the electronics people have a job ahead of them to get full control of the communication to the rocket.

Is it worth spending much effort to develop a new nose cone? They obviously missed a lot of telemetry, but as far as I understood was Emerald primarily a test of totrinskonstruktionen crawler transporter and recovery crawler transporter process?
Now I do not know how much they use CAD in CS, but otherwise should cone could probably reinforced with a grid structure without increasing weight. The question is whether it is too much of a digression in terms of helping the main mission on the way.
If the cause is rupture of the cone element due to an own resonance problem, a possible solution be to dampen / change the unwanted crawler transporter eigenmodes with weight rings placed in the right places inside the cone. Mass balancing is sometimes a more efficient solution than bracing.
No. Carbon fiber has nothing to do with baking to do. It is only the epoxy used as a binder crawler transporter which has a bearing on whether it is to be baked to cure. You can easily mold carbon fiber with epoxy that is cured at room temperature. In addition, the nose cone is so small that it will not be any problem to stack an autoclave of the legs that is large enough to harden it. What is interesting here is how hot is nose cone at launch. West system epoxy that may harden as low as 5 degrees begin to lose strength when it reaches 80 degrees.

Yes, it is resin (epoxy) that gives strength, but the strongest and most resistant type of carbon fiber material is probably still that is baked at high temperature - it is also the most expensive. In addition, the fiber direction of great importance.
