PECULIARITIES OF COOLING COMBUSTION CHAMBER OF ROCKET ENGINE, WHICH UTILIZE HIGH-TEST PEROXIDE AS AN OXIDIZER

open access: yesАвіаційно-космічна техніка та технологія, 2017
Interest in storable ecologically friendly propellant has increased recently. One of the reasons for that is convenience in storage, handle and delivery. The most interesting storable propellant for launch vehicles is high-test peroxide with kerosene.  A

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...

Assessment of the Interaction between Ammonium Dinitramide and Isocyanurate Bonding Agents for Application on Technologies of Composite Solid Propellants

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
This work investigates the interaction of two isocyanurate‐based bonding agents with ammonium dinitramide: triallyl isocyanurate and 1,3,5‐tris(2‐hydroxyethyl) isocyanurate, which contain alkene and hydroxyl functional groups in their side chains, respectively.

Liquid-Propellant Rocket Engine Throttling: A Comprehensive Review [PDF]

open access: yesJournal of Propulsion and Power, 2009
Liquid-propellant rocket engines are capable of on-command variable thrust or thrust modulation, an operability advantage that has been studied intermittently since the late 1930s. Throttleable liquid-propellant rocket engines can be used for planetary entry and descent, space rendezvous, orbital maneuvering including orientation and stabilization in ...

Characterization of Structure, Properties, and Energetic Performance of a 1:1 Ammonium Dinitramide‐3,4‐Diaminofurazan Cocrystal

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...
