Launch News MSC Tycho Brahe on Copenhagen Suborbitals HAET1X, Baltic Sea launch - Attempt 2

[C3PO]

The dummies head was banging around alot :headbang: .Is there a doctor here because I think this astronaut would be injured in some way, maybe a concussion?

Have a look at a cockpit video of a shuttle launch. If they had helmet cams, the video would have been a bit shaky too.

The capsule experienced a force of 26G on impact with the surface (and 9G on the second and final impact). I don't know how long that force lasted, but I'm guessing it was short.

It's been confirmed that the next model will have some kind of control system to keep the flight profile (more) vertical.

Ok so 26G's on impact doesnt sound so good as a person can pass out at 5G's and die at 9G's.

Edit:A person can die at 9G's if it is for a long period of time.An untrained person can handle 5G's for a few seconds.

Human tolerances depend on the magnitude of the g-force, the length of time it is applied, the direction it acts, the location of application, and the posture of the body.

The human body is flexible and deformable, particularly the softer tissues. A hard slap on the face may briefly impose hundreds of g locally but not produce any real damage; a constant 16 g for a minute, however, may be deadly. When vibration is experienced, relatively low peak g levels can be severely damaging if they are at the resonance frequency of organs and connective tissues.

To some degree, g-tolerance can be trainable, and there is also considerable variation in innate ability between individuals. In addition, some illnesses, particularly cardiovascular problems, reduce g-tolerance."

An untrained human can withstand about 5g of sustained acceleration (about 20 to 40 of instantaneous acceleration lasting only short period of time), although modern pilots can go up to 9 (using special g-suits and efforts to strain muscles and pushing thus blood back to the brain)

Negative G's are even worse - the limit here is about -3g.

Human body can handle much higher G's if the force is perpendicular to the spine.

Formula One drivers usually experience 5G's while braking, 2G's while accelerating, and 4G's while cornering. Every Formula One car has an ADR (Accident Data Recovery) device installed, which records speed and G-force. According to the FIA Robert Kubica of BMW Sauber experienced 75 ''g'' during his 2007 Montreal GP crash.

Car crashes at about 30mph can result in forces around 30g. The landing of this is likely to be akin to a car crash. Survivable, but not ideal. Also don't forget that the parachutes weren't properly active, so the target splashdown was a lot more unpleasant than expected

The 26g would have been for a fraction of a second.
