The Business Plan has 3 Stages:


Stage 1:

Testing of a ramjet-powered vehicle to establish altitude and velocity limits for its operation under the aegis of the Department of Aeronautical Engineering, Swansea University (Dr Zoran Jelic)


Stage 2 at Machrihanish Airport, Campeltown, Scotland: 

This is the full-scale operation using the 3km long taxiway there.


  1. A linear motor launch track on the taxiway; a delta-winged space-plane, the Swala OSV, mounted on a carriage on this track

    Stage 1 - take-off

  2. A ramjet under each wing, to take it to +/- 30km and perhaps as much as Mach 5

    Stage 2 - ramjets boost

  3. The ramjets are detachable and are parachuted back into the sea (as with the Space Shuttle solid fuel boosters)

    Stage 3 - ramjets jettisoned

  4. A solid fuel main motor to take it to low earth orbit and cold gas or hydrazine thrusters for precise positioning as used on the International Space Station

    Stage 4 - solid fuel motor to LEO

  5. The payload being placed into orbit

    Sage 5 - payload dropped

  6. Re-entry drawing on space shuttle experience, but probably using high temperature alloys in place of heat shielding because of the vehicle’s low ballistic coefficient


  7. Landing by gliding back onto the launch or similar carriage speeding down the linear motor track, using systems developed for autonomous landings on aircraft carriers.

    7 stages of Swala Flight

Stage 3 – Flotation of Swala Aerospace plc
