FRACTURE IN ROCKET PROPELLANT

open access: yesLe Journal de Physique IV, 1991
As part of a safety program, we studied the fracture of several rocket propellants under plate impacts and Taylor tests, thus examining fracture under both one- dimensional planar and two-dimensional axisymmetric loadings. Here we outline the experimental results for one propellant (termed Propellant B), describe the constitutive model developed, and ...

Composite solid rocket propellant based on GAP polyurethane matrix with different plasticizers

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Glycidyl azide polymer (GAP) has been prepared and studied for its application as polymeric matrix for composite solid rocket propellants (CSRP). Different CSRP based on GAP polymeric matrix with different plasticizers were prepared. A cross-linker based

Use of cryogenic components of propellants for liquid-propellant rocket engines and in life support systems of manned space vehicles [PDF]

open access: yesMATEC Web of Conferences, 2020
The cited materials show the use of oxygen, hydrogen, liquefied natural gases (methane) and fluorine as components of the fuel for liquid-propellant rocket engines (LRE). The reasons for the need to use oxygen as an oxidizing agent are indicated.

The design and performance on 200N-class bipropellant rocket engine using decomposed H2O2 and Kerosene [PDF]

open access: yesINCAS Bulletin, 2019
Mono-propellant thrusters are widely utilized in satellites and space launchers. In many cases, they are using hydrazine as a propellant. However, hydrazine has high toxicity and high risks in using for launch campaign.
