摘要

Abstract

Energetic nanofluid fuel has caught the attention of the field of aerospace liquid propellant for its high energy density (HED)

but it suffers from the inevitable solideliquid phase separation problem. To resolve this problem

herein we synthesized the high-Al-/B-containing (up to 30% (mass)) HED gelled fuels

with low-molecular-mass organic gellant Z

which show high net heat of combustion (NHOC)

density

storage stability

and thixotropic properties. The characterizations indicate that the application of energetic particles to the gelled fuels obviously destroys their fibrous network structures but can provide the new particleegellant gelation microstructures

resulting in the comparable stability between 1.0% (mass) Z/JP- 10 + 30% (mass) Al or B and pure JP-10 gelled fuel. Moreover

the gelled fuels with high-content Al or B exhibit high shear-thinning property

recovery capability

and mechanical strength

which are favorable for their storage and utilization. Importantly

the prepared 1.0% (mass) Z/JP-10 + 30% (mass) B (or 1.0% (mass) Z/JP-10 + 30% (mass) Al) shows the density and NHOC 1.27 times (1.30) and 1.43 times (1.21) higher than pure JP-10

respectively. This work provides a facile and valid approach to the manufacturing of HED gelled fuels with high content of energetic particles for gel propellants.
