Fluid thrust control system [PDF]

, 1968
A pure fluid thrust control system is described for a pump-fed, regeneratively cooled liquid propellant rocket engine. A proportional fluid amplifier and a bistable fluid amplifier control overshoot in the starting of the engine and take it to a ...

AI‐Powered Advancements in Food Analysis and Safety: Ensuring Quality, Protection, and Precision in Modern Food Systems: A Review

eFood, Volume 6, Issue 4, August 2025.
The role of AI in contaminant detection and spoilage prediction is underlined. One of the applications is using near‐infrared spectroscopy on a machine learning algorithm sample to determine if it contains any adulterants in olive oil. Also, trying to develop computer vision techniques that can soon be widely deployed to detect defects in the automated

Amine‐AlH3 Adducts as Energetic Materials for a New Generation of Solid Fuels

Chemistry – A European Journal, Volume 31, Issue 40, July 17, 2025.
New amine‐AlH₃ adducts offer a more environmentally friendly, high‐energy alternative to conventional rocket propellants, and exhibit ultra‐fast ignition. They can be synthesized by mechanochemical method under hydrogen pressure starting from aluminum metal directly or by wet chemical processes with AlH3.

Hypergolic droplet‒film interaction dynamics at high temperatures

Droplet, Volume 4, Issue 3, July 2025.
The whole reaction process can be distinctly identified as three stages based on the corona size and the temperature temporal evolution. In the coalescence regime, T* maintains quasi‐stationary values during initial contact, corresponding to hydrodynamic coalescence process. Consequently, the first stage is defined as the inertia‐dominant stage. In the
