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, the mission was simplified to a single-
The craft incorporates a sharp nose, and underside concavity, and the forward part of the wings slides forwards to reveal sharp leading-
Stabilising 'feathers' as on SpaceshipOne and SpaceshipTwo have been added to the wingtips; an autostable re-
One would envision the Swift’s lifting balloon being launched off the North coast of Scotland, allowing the Swift to re-
The craft was originally designed to use an uprated version of our nitrous oxide hybrids. Simulations showed that 600 litres of nitrous oxide was enough to reach Space (120 Kilometres apogee). The craft shown below used this propulsion system:
Swift Mark 5 variant:
The maiden flight of a small Swift Mk 3 test model can be seen here (double-
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 (neutral spiral stability).
More details of the Swift project can be found in the following downloadable Powerpoint presentation (updated April 2017): Swift_project

Swift Mark 6 variant:
It was decided to move the propulsion system offboard as with Spacedare, to allow different propulsion system choices. This also greatly reduces the re-
This redesign features a new cockpit, and a wrap-
By removing the nitrous tank from the fuselage, the fuselage is now effectively empty, which allows re-
To misquote Thomas More: “See me safe up: for in my coming down, I can shift (the C.G.) for myself.”
A vacant fuselage also allows a rear hatch.
Haven’t quite settled on the cockpit window material: flat panels or curved; seeking expert advice.
