Tycho Brahe (spacecraft)
Encyclopedia
HEAT 1X Tycho Brahe is a rocket and spacecraft project which is being built by Copenhagen Suborbitals
, a Danish
organization attempting to perform the first amateur
manned spaceflight.
The project exists of a rocket called HEAT 1X with a spacecraft Tycho Brahe attached on top of the rocket. It's being launched from a self-made floating ramp called Sputnik. Both HEAT-1X and Tycho Brahe are designed and built by Danish
non-profit rocket
group Copenhagen Suborbitals
with the co-designer of the spacecraft Kristian von Bengtson
.
to avoid blackout
. The heat shield is made of floor cork
. Life support will consist of a diving rebreather derived CO2 scrubber and breathing O2 system. Another compartment will contain both the high-speed drogue parachute and the low-speed main parachutes for deceleration. The sheer volume of the MSC will provide the buoyancy in the water. Pressurized nitrogen will be used for attitude control. The attitude thrusters are part of the non-pressurized volume of the spacecraft.
The first MSC has been christened "Tycho Brahe 1" and its first flight will be unmanned using a crash test dummy
. The man-rated Tycho Brahe will maintain the 640-mm diameter.
and the liquid oxidizer nitrous oxide
, which was used in their hybrid rocket
HATV (Hybrid Atmospheric Test Vehicle). The HATV rocket is only 1/3 size of the final rocket, HEAT. This HEAT rocket (Hybrid Exo Atmospheric Transporter) with liquid oxygen
and polyurethane
, will carry the MSC (the micro-spacecraft) above the 100 km boundary and into space. The MSC is named after Tycho Brahe
, and the combination is known as the HEAT-1X TYCHO BRAHE.
Gravity will then pull the MSC back to the atmosphere, where the MSC will land on water using parachutes.
The first HATV rocket was tested in a test stand on 8 March 2009.
Originally HEAT should have been fueled with paraffin wax but a ground test 28 February 2010 revealed that some of the paraffin wax only partially melted, instead of evaporating. The result was that HEAT-1X had less power than expected. A ground test firing of HEAT-1X-P (P for polyurethane) was conducted 16 May 2010. The results have not yet been released.
Stabilization of the rocket is by rolleron
s, a rather simple mechanism also used by missiles.
Ben Brockert, rocket builder of Armadillo Aerospace
and formerly of Masten Space Systems
, prefers the liquid oxygen
in HEAT-1X over the nitrous oxide

's rockets.
The first version of the HEAT hybrid rocket booster, is build from ordinary construction steel, with the exception of the cryogenic liquid oxygen tank. It is build from AISI 304 type stainless steel. The fuel is a polyurethane synthetic rubber, and the oxidizer is liquid oxygen. The oxygen is pressurized with helium gas. The booster can be shut down by radio signal from earth. Total cost is around $50,000.

They preferred another area and then gave a formal and written permission to launch from a firing range in the Baltic Sea
. Launch will be from a platform built for the purpose. The first full-scale test-launch to 30km is planned to be off the coast of Bornholm
sometime between 30 August and 13 September 2010 depending on the weather.
The launch will carry a crash test dummy "Rescue Randy" instead of a human pilot. Manned flight is still some years away.
Success criteria is completing the sea voyage and counting down - launch and recovery is a bonus.
On Tuesday 31 August 2010, the UC3 Nautilus
pushed the launch platform Sputnik carrying the rocket and spacecraft from Copenhagen towards the launch area near Nexø
, Bornholm
.
A launch attempt was made on Sunday 5 September 2010 14:43 CET
, 12 UTC+02:00, but this was a failure due to a stuck LOX
valve.
A test flight was attempted on 5 September 2010, using the HEAT-1X rocket.
The vehicle on board launch platform Sputnik, sometimes pushed by homebuilt submarine UC3 Nautilus
and sometimes towed by M/V Flora, moved from Copenhagen on Tuesday 31 August 2010 to Nexø
on Wednesday 1 September 2010.
Launch was initiated Sunday 5 September 2010 from Home Guard vessel Hjortø at co-ordinates: 55°02′57"N 15°36′11"E
The oxygen tank was filled, and the rocket was nearing launch.
First attempt did not fire, attention is focused around oxygen valve and electronics. The oxygen valve jammed. It had not been tested, the previous one was stolen along with the oxygen tank at the construction yard in June 2010.
The next launch attempt has been pushed to June 2011, beyond current launch window ending 17 September 2010, because the rocket might need to be taken apart to check the LOX valve, and ignition rods and LOX need to be replaced. Power to the hairdryer was supplied by Nautilus until the platform was evacuated, but the 20 minutes from then to launch drained the batteries and left the LOX valve unheated so it froze.
The new launch attempt was on June 3rd, 2011. Hjortø was once again used for Mission Control. The submarine was left behind as the Sputnik has been outfitted with its own diesel engines during the winter 2010-11.
After again experiencing a technical problem with the auto-sequence, the rocket and spacecraft went up in the air. After lift-off, HEAT 1X Tycho Brahe achieved supersonic speed but its flight path became less vertical, so Mission Control had to shut the engine off after 21 seconds. Maximum altitude is estimated to 2.8 km and the ground track was 8.5 km. Booster and spacecraft separated but a parachute was torn of the booster due to excessive air drag. Tycho Brahe's parachutes didn't unfold correctly either, so the spacecraft received a large bulge at the 26 G
impact. It is reported that it was water-filled when it was salvaged. The booster sank to a depth of 80-90 meters in the Baltic Sea A film of the launch from the pilot's point of view has been released.
