NASA followed last week's low-key engine test with the test-firing of a solid-fueled booster at Northrop Grumman's rocket ...

The rest of the hot exhaust is used to produce thrust by increasing its velocity through the nozzle. Since the exit velocity is greater than the free stream, thrust is created.

A basic ramjet has three components: an air intake, a combustor, and a nozzle. Hot exhaust from fuel combustion flows through the nozzle.

While the fate of NASA’s Space Launch System (SLS) rocket hangs in the balance, the agency is pushing ahead with tests of new ...

The typical time for first stage nozzle segments go into a service shop can be anywhere from 24,000 to 36,000 hours – about three to five years when running primarily in baseload service.

Instead, it is pumped into a separate reservoir through a separate nozzle at diesel gas pumps and injected into hot exhaust, ...

From the particulate filter, the exhaust gas travels past a nozzle which sprays diesel exhaust fluid into the stream of gases. DEF is made from deionized water and a very pure form of urea.

Unlike previous aircraft, the most advanced jets like the F-35 travel slower, which cuts down on the amount of hot exhaust it generates. The F-35 Lightning and F-22 Raptor are actually built with ...

An upgraded version of one of the solid rocket boosters being used for NASA's Space Launch System (SLS) experienced an ...

If it wasn’t already apparent, all rockets need to use a nozzle of some type to accelerate hot exhaust to produce thrust. The nozzle itself is nothing more than a specially shaped tube, which ...

So far, the new nozzle designs have been tested in the laboratory with exhaust as hot as 1100 degrees Fahrenheit. The scale model jet engine used in testing is a scale version of the F-18 F404 engine.

A nozzle is a relatively simple device, just a specially shaped tube through which hot gases flow. However, the mathematics which describe the operation of the nozzle takes some careful thought.
