I'd be interested to learn if the range-safety package had to be scaled up or down for the material change. The range-safety package is (usually) an explosive designed to rip open the booster in a controlled manner in case of loss of control. This permits the propellant to burn at altitude and at zero pressure (instead of in the thrust chamber).
Is it easier or more difficult to split the side of a composite booster?
Wow! I have many years experience in the aerospace industry. I have seen composites used, long ago, for upper stages, which operate in space. I have not seen that done for the while launcher. It should not be suprising considering what is being done for aircraft. This is really interesting and a real breakthrough.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
