Sentence examples for ram pressure from inspiring English sources

In this system (shown in Figure 8), a turbofan engine is built into the inlet of a ramjet engine to charge the latter with a pressurized stream of air at subsonic flight speed where ram pressure is insufficient for effective ramjet operation.

When static and ram pressure are equal, the columns have the same height.

As the ram pressure increases, mercury on that side of the tube is pushed back and the columns become imbalanced.

As has been seen, ram pressure plays an increasingly important role in the thermodynamic cycle of power and thrust generation of the jet engine at supersonic flight speeds.

They are less suitable for use in vehicles that must be sufficiently self-powered for subsonic takeoff, climb, and acceleration to supersonic flight speed; the subsonic ram pressure is insufficient to produce any reasonable amount of thrust, and so alternative propulsion devices must be provided.

Airspeed indicator, instrument that measures the speed of an aircraft relative to the surrounding air, using the differential between the pressure of still air (static pressure) and that of moving air compressed by the craft's forward motion (ram pressure); as speed increases, the difference between these pressures increases as well.

This is because many ICMEs are actually magnetic clouds, and the ratio of the magnetic to ram pressures is higher inside the magnetic cloud.

To characterize the solar wind by one index, we use the quasi-invariant (QI) index (Osherovich et al. 1999) that is defined as the ratio of the solar-wind magnetic to ram pressures.

This paper investigates the variation and effects of punch and die geometry, blank-holding pressure, top-ram pressure, lubrication, and drawing speed in the deep-drawing of C.R.1 steel cups of 0.9 mm thickness.

For flight speeds above Mach 2.5 or 3, the ram-pressure ratio becomes so high that a turbocompressor is no longer necessary for efficient thrust generation.

In this presentation we show the feedback from gas which is stripped from galaxies by ram-pressure stripping.
