Aspirespace experimental rocketry society
Ever since the Xprize competition was running, We've been inspired to design craft that could perform a suborbital flight to greater than 100 Kilometres apogee (the highest height achieved in the up-
100 Kilometres marks the official boundary of Space.
In order to design something that had a chance of ever being built, we simplified the mission to a single-
Our initial goal is to launch a radio-

The Swift model glided gently to the ground in a shallow turn. Despite the anhedral (negative dihedral) the turn was stable: the angle of bank remained constant as predicted (spiral neutrality).
More details of the Swift project can be found in the following downloadable Powerpoint presentation (updated April 2017): Swift_project

The craft will use an uprated version of our nitrous oxide hybrids and will be launched off the North coast of Scotland, to re-
Simulations show that 600 litres of nitrous oxide, which equates to a tank one metre in diameter, is enough to reach Space! (120 Kilometres apogee).
The craft incorporates a sharp nose, and underside concavity, and the forward part of the wings slides forwards to reveal sharp leading-
As you can see, we've incorporated stabilising 'feathers' as on Spaceship One and Two which was designed by Burt Rutan (my hero since childbirth). We didn't invent the parachute either, but it would be foolish not to have one; both Rutan's feathers and the parachute are fundamental additions that greatly enhance safety on this type of vehicle.
Swift Mk 5 has now been designed as shown above: it features a larger cockpit with smaller windows (but the same view), redesigned feathers, and a lower drag fuselage and nose. It also features a more rearward vehicle C.G. which reduces C.G. travel during the rocket burn as propellant is ejected out the nozzle.
