First Claim
Patent Images
1. A launch vehicle comprising:
- a casing;
a solid propellant located within the casing;
a channel through the solid propellant;
a geometric feature in the channel; and
a suppression structure, comprising a rod, located around a centerline for the channel and located entirely forward of the geometric feature with respect to a direction of travel of the launch vehicle, wherein the suppression structure is configured to reduce or eliminate an interaction of perturbations with the geometric feature in a manner that reduces or eliminates oscillations in thrust.

Abstract
A launch vehicle comprising a casing, a solid propellant, a channel, a geometric feature, and a suppression structure. The solid propellant is located within the casing. The channel is through the solid propellant, and the geometric feature is in the channel. The suppression structure is located around a centerline for the channel and located upstream in a flow path from the geometric feature.
