I am now working on the Liquid Oxygen (LOX) supply while I give my missile lots of time to dry between coats.
The LOX was stored in a double skinned tank with a vacuum kept between the two, hence the need for a vacuum pump to maintain this vacuum. The vacuum pump was scratch built from the spares box and is totally fictitious - sorry.
The LOX was supplied by British Oxygen.
As the LOX boils at -183 oC problems occurred with expansion and contraction of the pipes, to overcome this the supply lines were suspended on brackets, thus allowing movement as the liquid oxygen progressed down the pipe.
The LOX is not a fuel but provided the oxygen for the fuel to burn.
The fuel was supplied from the opposite side of the missile RP-1 (high grade kerosene), again on suspended pipes.
To avoid contamination nitrogen was used to push the LOX along the pipe, the two nitrogen trailers were scratch built.
Although LOX does not combust, if it comes into contact with combustible material it cause instant combustion to occur, great care and protective clothing were used.
An onsite shower was also provided. The last picture shows this, it looks to have a water tank above it.
