Good day All, Ok, time for some notes to go with the new pictures. The first as Jon states is the team, circa early 80's I would say maybe a year earlier. Barry at the front of the car, then from left to right; Peter Gazey, ex Blue Star project incidentally, Brian Sparrow, Mike Huggins, Mel Bettison, John Witney, Steve..erm can't recall the surname sorry; Steve was a very late addition to the team, and finally Denis Atken the "rocket man" himself. The next pic shows a better view of the rear face of the firewall and the pressure control for the propellant system, including the turbo pump. The pump, or part of it, can be seen in the bottom right of the picture; this is the turbine volute, the device just above the pump, tall and thin, is part of the steam generator that drove the turbine once the system was started. The spherical vessel was the used to start the turbo pump itself. I think these pictures will mean a little more when I get the history article finished. It covers in a little more depth the system as a whole. The next picture, looking into the tubo pump area gives a better view of the steam generator and it's controls. I now guess that the right hand pedal, in the cockpit, opened the flow valve to the starter, right centre of the pic, judging the route of the cable operating it. Just behind the control valve, the right suspension unit can just be seen, the vertically mounted screw thread etc.. Next pic is simalr to an earlier one, so I wont give any duplication on the control panel; what is interesting in this shot is the level of detail you can see of the rocket motor itself, middle right of the image, the rigid tube running around the back of the motor would have been used for the Kerosene injection in the missile, when the motor was run in the "hot" configuration. You can just about pick out the suspension units on both sides also. Next pic's of the control panel, showing the manifold to split the main pressure line from the Nitrogen tank. The following pics gives better detail of the turbo pump starter. The connection pointing outwards was where the HTP was filled from but only for the starter, a few ccm's; the other hemi-part of the vessel facing the firewall had Nitrogen gas to pressurise a diaphragm clamped around the bolt circle, the other bits hanging off of the vessel were pressure relief and other connections; all of this by the way from the origianl Black Knight missile. The pressure relief valve was used to regulate the rotational speed of the turbine.
