Today I started work on AIA’s Big Dumb Booster, a launcher designed for the company’s future Toehold Project Space Station Modules.
The Launcher is loosely based on the 2 stage BDB from Stephen Baxter’s “Space” novel. It’s design utilises decomissioned shuttle components following the program’s end in 2010. The basic principle is to use the existing technology in an altered format in order to lift large payloads to LEO. Designed as one shot, cheap launch systems with no unnecessary components, they are unlikely to be reusable (except SRBs).
In short, 4 SSMEs are attached to the bottom of a modified ET with a second stage payload mounted on top. 2 standard SRBs are bolted to the side for additional launch lift. The thrust and fuel numbers are similar to the current shuttle, so the second stage payload mass will be comparable to the total mass of the existing orbiter.
