The test result shows that maximum tolerance of the simulated ambient pressure deviation is about 14% under which the engine thrust uncertainty remains less than 1.0%.
Based on the results, analyses of mechanisms of the flame spread across solid fuel surfaces in various ambient pressures were suggested in this paper.
A fluid dynamic polymer-based contact sensor (100) measures ambient pressure (103) based on the resistivity changes across the sensor under different ambient pressures.
Experiments indicate that the ammonia catalyst reduced under low or ambient pressure is more active at lower temperature and stable in performance.
DEPRESSURIZATION valve, a valve in the hydraulic system for decreasing hydraulic reservoir air pressure to ambient pressure.
At 800 meters, the ambient pressure is 80 times that of the atmosphere, high enough that the pressurized injected CO2 is in a “supercritical” phase—one that is nearly as dense as the brine it replaces in geologic formations.
The equipment for underwater abrasive water jet under high ambient pressure and a study of eroding properties
The sc-C20 is metastable under ambient pressure, and is more stable than graphite at high-pressure (100 GPa), indicating that it can be synthesized through high-pressure.
Based on experimental data and numerical simulation results, effects of ambient pressure and base bleed on aerospike nozzle base behaviour are investigated.
The results show that flame-spread rates are sensitive to ambient pressure and decreases as the ambient pressure decreases in a lower range of ambient pressures.
But in a higher ambient pressure, the flame-spread rates are independent of ambient pressure.
