Solid-fuel rocket motors are used as boosters for the space shuttle, in satel- lite launch vehicles, and in weapons systems (see Figure P8.3). The propel- lant is a solid combination of fuel and oxidizer, about the consistency of an eraser. For the space shuttle, the fuel component is aluminum and the oxi dizer is ammonium perchlorate, held together with an epoxy resin "glue." The propellant mixture is poured into a motor case, and the resin is allowed to cure under controlled conditions. Because the motors are extremely large, they are cast in segments, each requiring several "batches" of propel- lant to fill. (Each motor contains over 1.1 million pounds of propellant!) This casting-curing process is sensitive to temperature, humidity, and pres- sure. If the conditions aren't just right, the fuel could ignite or the proper- ties of the propellant grain (which means its shape; the term grain is borrowed from artillery) might be degraded. Solid-fuel rocket motors are extremely expensive as well as dangerous and clearly must work right every time, or the results will be disastrous. Failures can cause loss of human life and irreplaceable scientific data and equipment. Highly public failures can destroy a company. Actual processes are tightly monitored and controlled However, for our purposes, consider these general criteria The temperature should remain between 115 F and 125F The humidity should remain between 40% and 60% The pressure should remain between 100 and 200 torr
