Advanced Intelligent Systems, Volume 4, Issue 5, May 2022., 2022 Existing autonomous pneumatic soft robots have a stiff fuel tank to transport the fuel and inflate the actuator. Inspired by pit membranes in trees, a chemical pump decouples the pressures of the fuel tank and actuator, while the fuel is transmitted to the actuator against the pressure difference.

Aluminized Enhanced Blast Explosive Based on Polysiloxane Binder
Propellants, Explosives, Pyrotechnics, Volume 47, Issue 2, February 2022., 2022 Abstract Drastic measures are taken in order to improve the properties of enhanced blast explosives. First, a binder with high reactivity as reducing agent is selected. The binder, platinum cure silicone, generates pyrophoric decomposition products in situ during the detonation.

IET Control Theory &Applications, Volume 15, Issue 4, Page 489-498, March 2021., 2021 Abstract For a class of conic‐type non‐linear time‐delay Markov jump systems, the asynchronous dissipative output feedback controller based on the guaranteed cost control and quantiser is designed in this study. In real applications, the system and the controller modes are always non‐synchronous, so we introduce the hidden Markov model to solve this ...

Geometrical characterization and performance optimization of monopropellant thruster injector
Egyptian Journal of Remote Sensing and Space Sciences, 2012 The function of the injector in a monopropellant thruster is to atomize the liquid hydrazine and to distribute it over the catalyst bed as uniformly as possible. A second objective is to place the maximum amount of catalyst in contact with the propellant
