dynamic pressure
Noun
Meaning
dynamic pressure (plural dynamic pressures)
(hydrodynamics) The pressure exerted upon a body in contact with a fluid due to the relative motion between the two.
The high speed of a rocket during its ascent through the atmosphere generates considerable levels of dynamic pressure that the rocket's structure has to withstand without buckling.
Synonyms
Examples
A low density TPS material might lack the tensile strength to resist spallation if the dynamic pressure is too high.
For a sail in the solar wind one AU away from the Sun, the field strength required to resist the dynamic pressure of the solar wind is 50 nT.
He had learned three essential things, Matthiessen sums up: * To rely on verbs of action, "which lend their dynamic pressure to both movement and meaning."
If the air on one side of the diaphragm is at the static pressure, and the other at the stagnation pressure, then the deflection of the diaphragm is proportional to the dynamic pressure.
Most rocket payloads are fitted within a payload fairing to protect them against dynamic pressure of high-velocity travel through the atmosphere, and to improve the overall aerodynamics of the launch vehicle.
Peak dynamic pressure can also influence the selection of the outermost TPS material if spallation is an issue.
