Proactive Robotic Grasp Stability via Tactile Safety Margin Feedback
Advanced Intelligent Systems, EarlyView.We introduce the tactile safety margin (TSM), defined as the ratio between applied friction force (Ffric) and maximum friction (Fmax) derived from grip force. A bilayer E‐skin with decoupled temperature, strain, and pressure sensing enables real‐time grasp stability monitoring through measured TSM values, allowing robots to proactively adjust grip ...

Advanced Intelligent Systems, EarlyView.This study introduces a data‐driven framework that combines deep reinforcement learning with classical path planning to achieve adaptive microrobot navigation. By training a surrogate neural network to emulate microrobot dynamics, the approach improves learning efficiency, reduces training time, and enables robust real‐time obstacle avoidance in ...

Liquid propellant combustion waves
27th Joint Propulsion Conference, 1991Design of efficient and stable combustors depends on accurate analysis of flowfields. In the present study, we examine combustion waves aIlSIng from hydrogen-air reactions In the scramjet flame holders with various ramp angles. TWo-iltep Taylor-Galerkin finite element methods are used to solve the Navier-Stokes system of equations.

Abstract : Liquid propellants have been the focus of periodic research efforts since just after the Second World War. Early efforts centered on the mechanically simple bulk loaded liquid propellant gun. A large number of experimental gun firings were conducted, and semi-quantitative models of the bulk loaded interior ballistic process were developed ...

Liquid Propellant Rocket Motors
The Journal of the Royal Aeronautical Society, 1953It has been said that a rocket motor is the simplest “ prime mover.” This is correct in theory, since fundamentally a rocket consists of a chamber containing a gas under pressure, having a nozzle at one end through which the gas expands, forming a propulsive jet. Since the pressure ratio of the rocket is always greater than the critical pressure ratio,

Liquid-Propellant Rocket Power Plants
Journal of Fluids Engineering, 1947Abstract This paper discusses some of the general features of liquid-propellant rocket power plants, and the propellant systems which have been developed. The object of the discussion is to call attention to problems requiring solution in order to improve the reliability and performance of liquid-propellant rocket power plants.
