Procedure of designing a pilot operated gas pressure regulator for launch vehicle fuel tanks

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016
The paper presents a calculation procedure based on the mathematical model of a pilot operated gas pressure regulator. The model takes into account the parameters of the feedback channel, the gas damper, the flow force at the main valve poppet and the ...

Transient Temperature Effects on the Aerothermoelastic Response of a Simple Wing

Aerospace, 2018
Aerothermoelasticity plays a vital role in the design and optimisation of hypersonic aircraft. Furthermore, the transient and nonlinear effects of the harsh thermal and aerodynamic environment a lifting surface is in cannot be ignored.

Semi-analytical solutions for transient response of one-dimensional saturated single-layer porous media under various permeable boundary conditions

Yantu gongcheng xuebao, 2023
Based on the one-dimensional basic equations for waves in saturated porous media proposed by Biot, a mathematical model for one-dimensional transient response of single-layer saturated porous media is established under various permeable boundary ...

Steady-state visual evoked potentials can be explained by temporal superposition of transient event-related responses [PDF]

, 2011
<p><b>Background:</b> One common criterion for classifying electrophysiological brain responses is based on the distinction between transient (i.e. event-related potentials, ERPs) and steady-state responses (SSRs).

Testing fluvial erosion models using the transient response of bedrock rivers to tectonic forcing in the Apennines, Italy [PDF]

, 2011
The transient response of bedrock rivers to a drop in base level can be used to discriminate between competing fluvial erosion models. However, some recent studies of bedrock erosion conclude that transient river long profiles can be approximately ...

Meshfree model for earthquake-induced transient response in a porous seabed

, 2021
The earthquake-induced seabed instability is one of critical issues that need to be considered in the offshore structure design procedure. However, the investigations of the earthquake-induced seabed behaviour are limited. Most previous studies regard to

Non-Monotonic Effect of Substrate Inhibition in Conjunction with Diffusion Limitation on the Response of Amperometric Biosensors

Biosensors
The non-monotonic behavior of amperometric enzyme-based biosensors under uncompetitive and noncompetitive (mixed) substrate inhibition is investigated computationally using a two-compartment model consisting of an enzyme layer and an outer diffusion ...

N₂O Decomposition over Fe-ZSM-5: A Systematic Study in the Generation of Active Sites

Molecules, 2020
We have carried out a systematic investigation of the critical activation parameters (i.e., final temperature (673–1273 K), atmosphere (He vs. O2/He), and final isothermal hold (1 min–15 h) on the generation of “α-sites”, responsible for the direct N2O ...
