One of our members has been struck down with the severely disabling illness M.E. which can leave him stuck in bed for months. Other symptoms include the inability to stand or sit upright due to changes in blood circulation.
He really wants to get into space, and why shouldn’t he? In weightlessness a lot of disabilities disappear.
So we were tasked with the challenge of designing a suborbital craft that could loft him safely into space and back down again, whist keeping him flat on his back during the accelerations of launch and re-
And so we conceived the ‘Spacedare’; so-
‘Spacedare’ is a one-
It is launched from a large hydrogen balloon at 35 Kilometres/115 thousand feet (near-
Modern European hydrogen ballooning is safe.
Falling vertically from an apogee of120 kilometres, our design and simulation software says that we need at least 1.0 square metres of drag area for every 45 kilos of spacecraft mass to keep the re-
As the cockpit rotates, it will cause sideways lift forces. The airbrakes on the upper and lower surfaces can be moved independently to aerodynamically counterbalance this lift force to prevent the craft pinwheeling.
To allow the pilot to get the best view when in Space, small compressed-
For landing, there are one or more stainless steel skids/skis mounted on shock-
This picture shows the Spacedare on the way up to Space. Our pilot is lying inside the lozenge-
The metal bar-
Here are the nitrous hybrid engine parameters:
Upon leaving the atmosphere, the yellow engine splits from the yellow tank to free the glider, and both are recovered by parachute.
On the way down to Earth, an electric motor slowly rotates the cockpit 180 degrees about the pilot’s middle so that he is still facing skyward. But the wings are now above him.
Now the drag of the sideways cockpit is a help rather than a hindrance, its area adds much useful drag.
There are many shapes of supersonic parachutes. Rocketeer Charles Pooley described the use of big airbrakes (barn-
Four large airbrakes deploy using electric motors to create lots more drag during re-
The underside of the cockpit has a heatshield employing a high-
The glider would be fibreglass and carbon-
