High Propellant Mass Fraction Highly Stress Relieved End-Burning Grain Structure
US Patent:
4696233, Sep 29, 1987
Filed:
Jan 31, 1986
Appl. No.:
6/824806
Inventors:
Ronald B. Paxton - Brigham City UT
Assignee:
Morton Thiokol, Inc. - Chicago IL
International Classification:
C06D 506
US Classification:
102287
Abstract:
An end-burning grain structural arrangement for a solid rocket propellant is formed by two parallel inhibited grain components formed into an "S" shaped cross section. The components form a fully case bonded system and the two components are separated from each other along the "S" which provides stress relief.
Process For Assessing The Effect Of Propellant Strain On Propellant Burn Rate
US Patent:
4815315, Mar 28, 1989
Filed:
Oct 13, 1987
Appl. No.:
7/107184
Inventors:
Ronald B. Paxton - Brigham City UT
Assignee:
The United States of America as represented by the Secretary of the Air
Force - Washington DC
Force - Washington DC
International Classification:
G01N 3322
US Classification:
73 35
Abstract:
The present invention describes a process for relating burn rate in a sample propellant to a strain field imposed therein by bending the sample propellant by a determined amount. The propellant is cast upon an initially flat plate having a single pair of fixed parallel walls. The plate is bent parallel to the walls before the test burn. Measurements of the thickness of the propellant before the burn and after the burn are related to the strain placed in the propellant by the bending. All measurements occur when the plate is flat.
