(Continued from the previous issue)Power to drive the shuttle and its aircraft load comes from expanding steam piped to the catapult from the main steam system(Figure 3.8.2).This steam is placed under pressure in large tanks(called accumulators or receivers)located under the launching engine.Steam is admitted to the receivers through the flow control valve(sometimes called steam charging valves).From the receivers,the steam is transferred at the moment of launch into the power cylinders.Steam acts directly on the pistons and propels the piston-shuttle assembly through the cylinders.A
