This is the principle of operation of a de Laval nozzle.

The hydrodynamics of a de Laval nozzle may also give a hint to the mechanisms involved.

Very nearly all modern rocket engines that employ hot gas combustion use de Laval nozzles.

Main article de Laval nozzle.

The fluorescence signal is captured by a photomultiplier a known distance downstream of the de Laval nozzle.

The nozzle, now known as a de Laval nozzle, is used in modern rocket engine nozzles.

The analysis of gas flow through de Laval nozzles involves a number of concepts and assumptions:

At this point he applied de Laval nozzles, which were generally used with steam turbine engines, and these greatly improved thrust efficiency.

The de Laval nozzle allows the most efficient ("isentropic") conversion of the energy of hot gases into forward motion.

Finally, the exhaust speed (and thus the efficiency) could be greatly increased to beyond the speed of sound by using a De Laval nozzle.

The gas flow through a de Laval nozzle is isentropic (gas entropy is nearly constant).

This work was one of the earliest discussions of the diverging nozzle, later known as the de Laval nozzle.

However, most spacecraft today are propelled by forcing a gas from the back/rear of the vehicle at very high speed through a supersonic de Laval nozzle.

The nozzle is a bell-shaped extension bolted to the main combustion chamber, referred to as a de Laval nozzle.

It is speculated that foam acts as a compressible liquid and enhances the thrust when used with De Laval nozzles.

The technique involves the expansion of a gas or mixture of gases through a de Laval nozzle from a high pressure reservoir into a vacuum chamber.

On a De Laval nozzle, exhaust gas flow detachment will occur in a grossly over-expanded nozzle.

Such an arrangement is called a de Laval nozzle, and is commonly used in propulsion systems such as rocket and supersonic jet engines.

Turbojets accelerate a much smaller mass of the air and burned fuel, but they emit it at the much higher speeds possible with a de Laval nozzle.

The device consisted of a cylindrical shell filled with solid propellant, with a number of de Laval nozzles installed in the nose cone.

Overnight, someone steals his de Laval nozzle, as well as his autographed picture of Wernher von Braun.

Modern rockets were born when Goddard attached a supersonic (de Laval nozzle) nozzle to a liquid-fueled rocket engine's combustion chamber.

A de Laval nozzle has a convergent section followed by a divergent section and is often called a convergent-divergent nozzle ("con-di nozzle").

Goddard first used a De Laval nozzle on a solid-propellant (gunpowder) rocket engine, doubling the thrust and increasing the efficiency by a factor of about twenty-five.
