Thank you--I helped Dr. Edward Jones (he's deaf) get a supply of parallel-wound paper tubes for Rapier-type test jet motors several years ago. His propellant formula at the time even included red gum from a particular Australian tree (I forget which species), but he achieved long, smooth, even-thrust motor burns. He and others have been tinkering to optimize the thrust-time curves, for a family of motors (Dr. Z. had also developed a family of Rapier motors of different sizes, thrust levels, and burn times).
